Don't tell my wife Like I tell other people. some like to fish, some like to bowl, I like to make.

3 years later... took ages to find a good painter willing to take on the project. These days insurance jobs with small panel fixes seem to be more profitable. Luckily I found someone willing to do it in the summer months of this year while the insurance workload is reduced. Prepping... Overall quite happy with the result. Couldn't contain myself and started puzzling together the undercarriage the first chance I got. Pulled lines in the trans tunnel and assembled the suspension component. On the wheel first the first time since 2017!

More pis of it finished up The bottom plate was beat up a bit and bent from floor jacks. So I took off the old one by drilling out the spot welds. I then drew up the shape and had a new one laser cut. The center plate that is welded to this plate, I re-made it as well, but out of 304 stainless steel. This way I can leave it a brushed stainless finish after powder coating and it is a good place to use a floor jack. I then spot welded on the larger plate in the original locations I then tigged the seam between the spot welds Then tigged on the center stainless plate Then blasted the entire cross member and powder coated it in a super black semi gloss powder coat. Powder coated the motor mounts as well I always first do a primer powder coat that is sandable I sand most off this off to fill the small blemeshes Then final coat Finally the brushed stainless plate for the floor jack Next up is getting a new transmission, then finishing the exhaust

Been a while since I posted any updates. Been moving along. For the Turbo car I decided to build my own wheels. Ill CNC machine the center sections myself and have the lips and barrels spun for me. I really like the old SSR RS8 wheels but finding them in the correct bolt pattern, offset, and caliper clearance is impossible. I fould a set close, from Japan and had them shipped over. Since this car uses Z31 hubs and such, the spacing is out much more than a standard Z so I need a bit more positive offset. I dissasembled the wheels and scanned the center section into my computer and reverse engineered the shape. Next I re-assembled them and had the 245-45-16 tires Im going to use mounted. I test fitted them to the car, and close, but not good enough. This is the fist time this chassis has been rolling on its own wheels in 27 years. Its been on a cart or a lift. Felt good to see some progress now that the suspension, brakes, and cross-memeber are finally complete Scanned this complete assembly and put it in CAD. Now I have the exact shape of the tire on the rim. Cool cross section of it. Finally I scanned the side of the car, put it into CAD. Now I can adjust my wheel center offset for caliper clearance, and adjust it to work with new Lips and Barrels I will order for the proper offset and fit to the car. Having it in CAD alowed me to look at it from every angle and check all clearances, for calipers, springs wheels lip, ect. Even compressing the suspension to make sure I have fender clearance at full travel Final wheel spec is: Rear - 5 lug = 245-45-16 on 8.5" width rim- 27mm positive offset, 2.25" outer lip on the rim Front - 5 lug = 245-45-16 on 8.5" width rim - 31mm positive offset 1.75" outer lip on the rim Next I need to find some time to program the CNC and start cutting chips. But I got distracted on the NA car, so that update is next.

Three weeks until I'm home and properly working on the car before a long road trip. I've been creating a detailed list on some Google notes of everything I hope to accomplish. I'll update once I truly get to it, but for now just wanted to share my excitement for my new brakes. Was in Utah about two weeks ago for a handful of days for a music conference and my brother was kind enough to let me borrow his truck to drive up to Logan just for one evening to have a quick dinner with the siblings up there and I took a quick trip to my folks' place late in the evening and opened up some of the parts to keep my motivation haha. Also had a big box of new seals from Resurrected Classics. They were kind enough to give me a steep discount on their weatherstripping kit when I asked if I could get it without the door seals since I had already purchased the S30 world seals before they released their kit. Looks like they were kind enough to give me the discount and kept the door seals anyway! I'll be making a thorough comparison of it against the Precision kit I have, mostly to see if it's truly far better for some of the worst fitting parts.

I have two heads in stock as I type this so the head can actually be purchased. I can't help that you can't afford it. That's a feature not a bug. For the very beginning my goal was to provide the components so that talented engine builders could make the decisions on the types of components they wanted to use. Based on what I've seen and taking the pricing of the relatively simple L6 head as the baseline I highly doubt it. I'm not really sure what I did to put a burr under your saddle but you remind me of the guy that starts a fight in the line to get into the club because he can't afford the cover charge. Just get out of line and go somewhere else.

He's saying although we are launching a DOHC head in 2024 we readily admit it will be pale in comparison the mighty KN20 from Datsunworks. At least that's what I'm hearing.

Thanks for the replies and comments. Time is always an issue, however Im at the age now where my daughter is 26 years old and working full time. Been married 30 years so the wife is obviously understanding of my hobbies. Hopefully continuing to make progress regularily. Hoping more people come back to the forum and participate in the community. Here is a picture of me and my daughter when she was probably 2ish years old, same car Im working on now. I need to get her back in the shop for a new photo - Time flies

Hi everyone, I am at a good point with my build and wanted to share its history since its one of the few running and driving VQ37 swapped Zs in the country. I am going on over a decade of ownership. I originally bought the car from New Mexico and brought it over to Colorado. Come to find out, it was once a Colorado car also. I picked it up in primer with a rebuilt engine but not really knowing too much about it since all I had were photos and the owners word. The previous owner used it for autocross. The entire interior was missing and it had a rats nest for wiring. I remember it had a switch to manually turn on the fans. It also had a full radiator support and driver side frame rail replacement from a donor Z. I got lucky that this was done really well, I have had no problems getting the car aligned over the years and it drives straight! I saved some money and got the car painted in black, the car was originally a yellow car. The painter actually welded in floor boards and frame rails and closed up the wheel wells from where they were cut for the ZG flares. The rear hatch had to get replaced since it had an inch of bondo over the key hole. Luckily, I was able to track a hatch from a 240Z in the junk yard (when is the last time you have seen that haha). I added sound deadner to the interior and then took the car to an upholstery shop to get the interior put it. I also added some nice gauges. I was able to source some cheap Watanabe 16 inch wheels from yahoo auction Japan. They were different colors but I ended up paying around 900 usd after air shipping them spent another 300 getting them powder coated. I also picked up my Recaro seats from Japan. To this day I have no idea what car they came from but they are one of my favorite parts of the car. The SUs where swapped out for a triple Mikuni 44s. I drove with those and even had them tuned but they were too finnicky at altitude. During this time I got into flipping carbs for resale. I didn't want to deal with the Mikunis and decided to swap to fuel injection. I ended going Jenvey ITBs on Haltech. This setup actually worked great for about a year and even made it to the main page of my local Cars and Coffee. Around that summer I started to develop some running problems where I was running too rich. On my way to the tuner the worst thing happened. The car caught fire. From what I could tell, the itbs backfired and caught the fuel line on fire. If anyone is running itbs on an L Series, I highly recommend an airbox. I got really lucky since a guy like 2 cars back behind me had a fire extinguisher and that the radiator hose blew and stopped the fire. I sent the car over to my tuner/builder and waited on my insurance adjuster to visit the car. I was able to get a full payout through Hagerty and that kickstarted the funds to get my Z back on the road again. I knew I was done with L series. I never really wanted to build something that close to race car since I mostly drive my Z on the streets and occasional canyons. I wanted to stick something Nissan that could remain relatively stock. Something I could start up and just drive. In the past I almost swapped VQ35HR motor and have always had that build in the back on my mind but I noticed that the engines were almost the same price as the bigger brother VQ37. So I went with a VQ37 out of an automatic AWD G37. The reason I chose that engine was to avoid 370z's had been driven hard and the auto engines were cheaper with less mileage. The only change to the block that I needed was a lower oil pan from a RWD VQ and its bolts. I sourced a transmission directly from Nissan since at that time it was actually only about 500 dollars more compared to a used transmission. I looked recently and it seems like the transmission have doubled in price since 2021 when I bought mine. Here are the photos of when I got her back. We ended up putting some flake in the engine bay since I grew up loving lowriders. I also installed a GTR intake conversion. It ended up being a bit of a hassle since the custom fuel rail didn't clear the injectors. We had to extend the fuel ports on the fuel rail to make them taller so that it could clear. I added a catch can since the car is set to vent to atmosphere. I pulled the headers and stripped them and cerakoted them also. The custom hood didn't make it out of the fire so I went carbon fiber. Next I ended up getting the intakes extended to the front of the car to make it a true cold air intake. I recently took the Z engine harness apart and reloomed it and fixed one of my turn signals. Come to find out one of the wires was cut off. With the help of Dave Irwin, I was able to track down all of my missing grounds and also why both lights would blink at the same time (bad switch). I had an extra parts turn signal switch which I harvested and was able to get everything to work out. I recently tackled getting my horn to work. I have never got it to work since my entire ownership. The guys at classiczcar forum really helped me trouble shoot it. Come to find out, my only horn didn't work and for some reason my steering rack wasn't grounded. This is pretty much where the car is now. I took her to a local car meet today and I am hoping to just get more seat time with her. If anyone has any questions about the car or the swap feel free to message me.

if anyone's still tracking this build I have what might be a last update since the car is mostly done (lol is it ever done?). I finally cad-designed the front fenders and then had a local shop 3D print the parts, then took that to a bodyshop to integrate into the existing fender part and paint it. After that I overlayed the inside walls of it with carbon fiber for added stiffness and protection. I also cut the lower part of the rear fenders and put in a horizontal cf winglet to better extract air. Overall I think it looks great and the resulting new parts helps downforce a ton by extracting air from the wheel wells.

Since that broken rear differential a lot has happened.

Next order of business was electric fan and shroud, and radiator hoses. I chose the 2016-2019 Camaro single SPAL 18" fan. it will be PWM controlled and is a very popular choice according to the internet as it can flow 5000CFM. Although I cut up the factory shroud to "work" I felt like I needed something fancier. modeled up a base to start working from and had my friends at laserbros in NC laser cut and bend it up. Should have gone one or two AWG thicker so added some bracing as well as some mounts and very happy with the final product. Cut down the radiator and inlets and outlets on the engine and welded on some -16an bungs, made up a couple hoses. in the last photo of the "hose installed" you can see the end of the pipe for the intake I welded into the chassis I mentioned in the previous post. Also decided to move the alternator to the other side of the engine to get it away from the heat. When i pull the engine to paint the bay i'll design and make a bracket to permanently mount it over there.

I just wanted to share something pretty exciting in my world. 5 weeks ago I overheard a friend talking about how hard it was to get any machine work done. And it hit me..... I know how to rebuild heads I just need equipment. Did some research and found that 4 of the main shops in the area have sold out or retired. Told the idea to my father in law. And was just spit balling with him. I dont have the cash to start anything and it was just an idea.. well he gave me and my wife a rather large gift and I have now bought a storm vulcan 85b blockmaster and a winona van norman Ph-2000L valve ane seat machine. Still need a valve grinder and obviously tons of tooling. But im excited to see where God takes this. Been 25 years since ive done and work but am excited to get back into it. Plan to get the surfacer going and try to drum up some buisness to make some income to buy more tooling. I onoe they are not the best machines bit they are functional. Just wanted to share

Hi,guys, after one year off with other work, i put back the engine with reground camshafts, and ready for new start !😅 Wait and see ,and Happy new year

My custom made 3d printed aero hood latches are mounted.

Went out for some Auto-x this weekend, and had a proper blast. Highly recommended for anyone here who still hasn't gone to try it. Enjoy a slow lap, some V8 noises and straight cut gearbox whine. I have a handful of things to think about and address moving forward, but overall I'm very happy with where this sits. Next up is OnGrid at the Ridge in late July for more testing, and maybe, just maaaaybe a little redemption.

Good progress over the long weekend. Paint, bondo and fiberglass is mostly a waiting game which is pretty annoying. Got the duct glued together and painted so it looks like something. Trimmed it up a little and we are in great shape! The holes in the hood are a little bit large, but that's ok, and will likely get solved with a new hood (fiberglass) or something on top. Also got the transition piece painted which is exciting! This will help blend the splitter into the air dam, and will get taped onto the splitter once I put some trim on top of it. Need to get to work on the new intake pipe as well, going to put the filter over near the wheel for now. In the future, I'll flip the manifold and pull air from the cowl/wiper box area, but that's a bigger lift in terms of fabrication. Can't tell you how excited I am to have a metal fabrication project after 10 months of composites.

Meh, he's a paid supporter of the site. I figured I'll give him his moneys worth

I started typing a number of snarky responses and have settled on Wow what a shitty thing to say.

well old story , but MAG58 was right, mercedes M104 head is possible on a datsun L28 stroked , build is not over but we will see what happens soon bye bye Didier

**UPDATE Went to court yesterday and basically played dumb. Told the judge that "I went to the state ref and he told me since the car is so old that he couldn't do anything to certify it. So how do I go about taking car of this ticket. The vehicle is a pre smog vehicle so I've never had to SMOG it" The judge said "Ok so what Im going to do here is dismiss the case cuz it seems like your car doesn't qualify for an inspection. Sorry about the inconvenience Mr. Soto" I tried to play it cool but I was so happy. After reading all the horror stories from other people about having to revert to stock and all that I was lucky I guess Hope this thread helps someone going through something similar

Greetings Everyone, Due to the increase in spammers HybridZ, registration has changed from being automatic to manual. That means one of the Admins will need to approve any new registrants. If you ask or tell someone about HybridZ (please do) let them know registration isn't automatic anymore. We'll do our best to stay on top of any additions and hopefully you all will see a lot less spam. Thanks, The HybridZ moderation team

Love the way this is coming out. its been a challenging balance to thread between making everything neat and tidy and making sure I remember its a race car and needs to be functional. decided to polish the intake manifold and turbo, which looks great but upkeep is gonna be a challenge. exhaust is mostly done and welded. need to make a fancy tip for the back. wrapped the downpipe and mid pipe. need to pull the manifold and wrap that too. originally made a open dump wastegate but then changed it up to recirc it because we have a couple tracks with some noise restrictions. I'll order another v band and wastegate outlet so i can cap the exhaust and run it open if the track doesn't have a dB restriction. Fuel system is done. bulkheaded thru the floor. 3d printed some mounts and have it mounted along the floor. injectors are in. got most of the turbo lines made up. opted for the turbosmart oil pressure regulator for the turbo. i've never dealt with a turbo this small and man its a challenge to fit everything. drain is really tight. hits v band and clamp but think i may have the puzzle solved to make it work. fuel fill is welded up. went with stainless to mitigate the risk of corrosion with ethanol.

Was not implying that the only way to get work done on a project is to not have a wife and daughter!!! I can see how that could have come across. Mine is 14 and will be a freshman this year. Ive got 4 years..... Then who knows. As she has gotten older I've been telling the stories of her helping me in the shop when she was little. Her stepping into a drain pan full of oil in ugg boots that I promptly threw away with out telling mom, Me hearing a pppsshhhh noise and I turn around to see her with a my blow torch pointed at her face, Praise the Lord she didnt click the igniter She would have been around 2 also at those times.

Long week number like 200 but happy with the my progress. Made a tweak to a color based off a cadillac cts5 v blackwing. Its a bit more "copper" tone of orange than I was picturing with the modifications but I am very happy with it. As soon as I started pulling the masked off areas and was seeing the contrast with the grey I loved it. Did get some fisheye on one door so I'll have to fix and respray that at some point and a couple sags/runs in the clear to sand out, but I can make some serious progress on the build now. did get the engine stripped down as well. Bearings, rings, valve springs and a gasket kit have been ordered to freshen it up. but otherwise everything measured out good and seems like a good starting point.

Hi everybody, long time for updates. Been quite busy with kids and a very nasty divorce going on. The good news is my garage and cars are still intact and I am still making progress, although very slowly. Car is very close to track testing. I decided to have a new pair of steering arms machined to match the front geometry. I will post more when they are finished. In the interim, I took the time to catch up on some side projects I wanted to do. With the advancement of AI, some of the projects I considered impossible a couple years ago have turned out to be quite easy now and very inexpensive. Based on Arduino technology, I have integrated a motion sensor into my data acquisition system. I use a Race Technology DL1 Club box which is limited to 8 analog sensor inputs, but can decode an almost unlimited amount of CAN signals. So I built a circuit that decodes the motion sensor and outputs a CAN signal. I now have 3-axis roll, pitch, and yaw angles along with speeds and acceleration live data. It will all be packaged in a small box that mounts in the car. Next is a infrared tire temperature monitor. A 16x4 temperature array sensor once again combined with Arduino and CAN output board. I am trying to package this as small as possible so it can be mounted on brackets roughly 4" above the tire. Again real time data of inner, middle, and outer tire temps while driving. Hopefully saves a lot of time when dialing in the camber and pressures. More to come...........

Been a long week but got everything completely stripped and got some epoxy primer layed down on all the metal surfaces. have plenty of body work to do but atleast its sealed and protected now. Hopefully in the next week or two i can get the bodywork done and get some color on it. I did talk to john and his comment is "I don’t claim to be an expert on bonding. But in my experience cracking at a bond line is often due to inadequate surface prep both the underside of the fiberglass and the underlying metal), poor bonding agent, not enough bonding agent, cheap body filler, and/or excessive flexing of the unibody. On the other hand, I know a lot of guys who do the bolt-on installation. For performance applications, it can be an advantage for working inside the wheel well". With that said I think I will spend the time to make the fitment as good as possible and make a last minute decision based on how well it fits/looks.

Carbon fiber door and door cards came in, these things are super sexy 🥰

Without the oil cooler, my water temps were never an issue. Never over 200 on track. When I put the Aviaid Mangusta pan on the car it had a provision for an oil temperature sender. Even though my water temps never got too hot on track, once I installed an oil temp gauge, I discovered that my oil temps were getting near 300F. I added the Setrab 34 row cooler, and my oil temps stay below 250F.

03-25-2026 ATLAS Z UPDATE: I got some of the fittings in I need for my crankcase pressure to catch can to intake setup. Also tall of my carbon fiber panels have been cut, final polishing on roof section then ready to ship to me and bond them on! Then make the borders shiny!

That has got to be the best balance of Form and Function of a Datsun that i have EVER Seen!! Absolutely amazing!!

Got it off Amazon: https://amzn.to/4aS32Br And picked up a male pigtail off eBay: https://www.ebay.com/itm/134129914749 I actually replaced the wiper arms too. I used 93 miata arms which bolt up to the stock datsun wipers mechanism. Passenger arm is a little long so I may shorten it. For wiring, I followed this guide: https://www.electronixandmore.com/resources/automobiles/datsun/index.html Note this is very specific to the later wiring for 1978(maybe 1977 too) and would not be applicable to earlier years.

Great work so far! I’m sure this will be an awesome build. I suspect you will be running fender flares or a wide body kit seeing as your wheels are poking out a bit?

Yes, still working on then, just have not posted anything. Bought some expensive components that take time to recover from. A blank PAMS head, that I then designed and has DelWest make me titanium intake valves, Inconel mnemonic stainless steel exhaust valves, also MoldStar 90 seats and guides. Had it assembled, and ports cleaned up for some nice flow numbers. Also purchased a Nismo 6 Speed Trans that was also strengthened and modified by HPI in Japan. I take some progress pics soon.

Picked this up from local hot rod shop for my 240z SBC 350 project about 13 years ago. Circuits: Electric fan relay Fuel pump Radio and amplifier Power windows Summit Racing/parts store etc probably have this fuse box.

The hairlines weren't that bad, it was the handful that were going through the edge of the rotor that I was worried about. Friday marked my first return to the track in almost 2 years. Knocked off a bunch of rust, the car worked the whole time, and I made a couple changes that were impactful and improved the car. I went pretty slow, so y'all could enjoy some v8 sounds for longer than normal

It was a good idea not to wait on rebuilding the 3.54 diff. The new LSD arrived weeks after I expected it and there's no shot I would have been able to swap it into the spare R200 before my trip. I'm excited to get this together in the winter though!

Some of their stuff is good and some is hot garbage. Max the owner doesn't stand behind his product and has a tendency to try and blame "modifications" to your car as the reason. I have a lengthly (4 page) post on classic z car about my problems with his door assemblies. Resurrected Classics door problems I have their door weather strips and their fuel filler neck and the are excellent. My advice is no matter what you buy test fit as soon as it arrives and go from there. The doors were so bad that I ended up not using them. Max refuses to refund my money so I make sure to take the time to tell people about my experience. Do not trust what he says as he says whatever he needs to to get out of doing the right thing. Caveat Emptor with this guy for sure.

You should really just post on FB because they love trolls and useless posting there

For a street car I think the rails make sense. For a race car that has a cage perhaps not. For a similar amount of weight you can triangulate the cage with tubing on top of the floor that extends to the suspension pickup points.

2.0 is coming along.

My opinion: Flares because your tires are fat and need room = cool. Skinny tires that should fit stock but spaced way out anyway = not cool. It's in the same vein as camber to me. Negative camber for better handling? Awesome. Crazy negative camber because you want people to know how much camber you have? Stupid.

After almost 25 years, still together.

My shirts arrived today, with the wait - huge thanks to Ryan for tackling this big job that benefits all of us and HybridZ! It was difficult to choose amongst all of the colors but very happy with my choices!

Unfortunately, it is too late. Maybe for round 6 in a couple of years Got the shirts in and will start breaking things down and shipping things out next week. This week is busy with work travel, so appreciate your patience while I get a few out each day on my lunch breaks.

They received all of the shirts without backorders and are starting on printing this afternoon!

I really wish things would swing back towards the forums. I can't tell you how many times I know the answer to or could add to a post on FB but I don't since it really has no longevity. I always felt like I was adding to the overall knowledge base when I posted here. I can go on and on but I really hate it.

I want to thank all of you here for giving me inspiration for my build. I have adopted the Hybrid Z name for my build years ago since this site provided a lot of information that I consider priceless. I was able to meet some great people at ZCON, some that know my build and others that just wanted to say hello and compliment me on my build. When I built this car I built it as my version of what a Z should be therefore I know a lot of people were not going to like it since it was my vision and nothing else. Taking my car to ZCON for the 1st time and walking out of there with these awards it’s just incredible, especially with all the awesome cars I was competing against. It’s great to see the judges appreciate all the hard work and effort that has gone into it. These are the awards I received. 1st Place in Ultra Modified Best Engine Gold Cup- This was totally unexpected and shocking it was given to a Z with and LS3 since most of these guys are Nissan purists. Again, thank you all for your support and keeping this site alive.

an LS is also vastly more expensive then a traditional 350 swap. He should do whatever he wants to do.
