  1. FPR and Fuel Pressure Help

    So I am doing a Megasquirt EFI swap as well as a Turbo motor swap, using Green Giant 440cc injectors. I have a brand new stock replacement fuel pump already installed on the car, and I know the stock FPR is around 35-38psi if I remember correctly. What is the maximum fuel pressure the stock pump can put out? I am looking at getting a new FPR as I will need more fuel pressure for this setup, but I am trying to figure out exactly how much I will be needing and also if my stock fuel pump needs to be replaced in order to achieve higher pressure. Any suggestions on a good FPR would be great as well. (and fuel pump if needed) 1.Can I use my stock replacement fuel pump? 2. How much fuel pressure should the turbo motor and megasquirt setup have? (green giant 440cc injectors, p90 head, dished pistons 7.31:1 cr, base tune of 220-230hp apox. will be tuned to 300whp) 3. FPR reccomendations?
  2. Looking for l28et

    I've got a turbo manifold if you're interested.
  3. LY28 crossflow L Series Cylinder head

    Pictures dont show up.
  4. FPR and Fuel Pressure Help

    stock replacement from a new manufacturer, looks identical to the original. I couldn't find any specs on what the fuel pump put out from the listing.
  5. FPR and Fuel Pressure Help

    1. I have no problem with buying a higher pressure fuel pump, I just couldn't find what the stock one is rated at to see if it is needed in the first place. (What would be a good aftermarket alternative?) 2. Okay cool, that gives me a general idea of where I need to be at least. 3. Thats exactly what I was looking at, good to know. Thanks for your input, you've been extremely helpful!
  6. Hello everyone! Im new to the Hybrid Z forums so I thought I would start a build thread for my build on my 1975 280z. Current car: 1975 Datsun 280z Mods: Subaru Power Steering conversion, Full Eibach suspension, aftermarket swaybar + full polyurethane bushing conversion, Toyota front disc conversion, aftermarket A/C installed, 240z driveline, (im probably missing some things so I'll update it as I go.) I have roughly 20 years of receipts of all the work done to the car. I just recently acquired the car so everything listed above was done by the previous owner. Now here is my plans for the rest of the car: [Key --> Green = Acquired Crossed Out = No longer using ] Rebuilt Turbo Spec Motor 7.31:1 Compression (N42 block/P90 Head) Either T3 Precision Turbo or T3 Turbonetics Arp Head Studs External Wastegate + Blowoff Valve + AFR + Boost Gauge Oil Cooler Turbo dizzy 82/83 280zx + shaft Megasquirt EFI kit from Softopz Green Giant Injectors / 440 cc Supra Injectors (For Sale, Message me if interested I will ship at no extra cost) Turbo Oil pump (thoughts?) 240sx throttle body + Sensor Intercooler + Piping Oil Pressure T for oil lines to turbo (in & dump) 2mm head gasket to lower compression to 7.8/1 wastegate Downpipe (need a dump tube as well for the wastegate) Turbo Manifold(x2 anybody want to purchase my extra?) + wastegate adapter 2.5" exhuast / black widow widowmaker Upgraded Ignition System (not sure which to go with yet, suggestions??) NGK Plugs Pallnet Fuel Rail Kit + Throttle Body Spacer Electric fuel pump upgrade + New Pressure Regulator ------------------------------------------------- UPDATES: Update 11/3/2017 - With some great info/advice from the comments, I am highly considering going with a megasquirt plug in play kit made by softopz (just waiting on his reply at the moment). I've also decided I definitely DO want a bigger cam, so any suggestions on that front are helpful as well. Also I have added that if I go the megasquirt route I am ordering a pallnet fuel rail to compliment it. Update 11/4/2017 - Alright after meticulous research, hours of comparing prices and talking back and forth to people who have done the cam/turbo builds and the potential power gain (and I do mean COUNTLESS hours of this haha), I have decided to completely ditch the whole cam and head upgrade idea and go the turbo build route. For almost the same price (actually a bit cheaper) I can get alot more smiles per gallon with the turbo build. There just isn't enough power to be had on the N/A build for the amount being spent. So as of right now this is the game plan. I will continue to add to this as I see fit, everything will be updated on this original thread post. Part 2 11/4/2017 Just went through the receipts on the car (dating back to the late 90's) and boy was I in for surprise! All of the tedious work to maintain the stock L28 has been completely gone through by the PO! For example the timing chain kit from Z Motorsport has been installed, Tune up kits routinely done, fuel pump and filters / lines replaced, harmonic balancer replaced, and the list goes on. I couldnt be more happy with this purchase!! Did I mention the PO gave me a close ratio 5-speed for the car?! This car amazes me and I am very thankful that it has had such meticulous care over the years. Update 11/7/17 Added some parts to the list. Also purchased a turbo manifold on facebook for 150 bucks! ***Update 11/10/17**** I have purchased a complete rebuilt L28 turbo motor setup at a very very good price! Here are the engine specs: L28 N42 Block with dished pistons, P90 Head, N47 intake, turbo manifold, Pallnet fuel rail + Fuel pressure gauge, 440cc supra injectors, rebuilt chinese housing turbo with turbonetics internals, turbo dizzy, and assembled with ARP studs. Came with some other misc parts as well. Update 11/13/17 Link to spreadsheet for parts list: https://docs.google.com/spreadsheets/d/1iOiWBJyjQH3KEkLnBor0snwgOvXaUo4I0qIo1ZDYFZo/edit?usp=sharing
  7. Turbo Dizzy (82/82)

    Looking for a turbo dizzy out of a 82/83 along with the oil pump shaft. Please let me know if you have one and would like to sell it.
  8. FS: Aluminum Radiator + Fan & Temp Switch - CA

    I'll buy it if you're willing to ship it. I'll pay shipping.
  9. So you may have seen my build thread. I am converting my N/A L28 to turbo using the stock N42/N42 motor with a 2mm HKS head gasket and a compression ratio of 7.65:1. Upon my research I have found that finding the exact turbo for this build is alot harder than I though. And requires some pretty good knowledge of how turbos work, compressor maps etc.. I've done some searching here and there but havent seen anyone doing my setup so far with the N42 combo with the 2mm gasket. Feel free to chime in and I'm curios to know what turbos you guys are running, and also if you have some helpful advice to steer me in the right direction that would be very helpful as well. I will continue my research either way. Here is what my goals are: Full spool by 3k-4k rpms. 300whp capable. 500-900 dollar price range (preferably around 700-800 if possible) These are the things I can think of at the moment, I am probably forgetting something. but a 3-4k spool seems like the best for the rpm range of this build (6500). Feel free to chime in with any advice, criticism, or whatever you'd like! I am wanting to learn, and wanting to make sure my setup is right the first time. Like I said earlier I will continue this research but I figured I'd put this post out here so I can see what people have to say. Shameless build plug >Click Me<
  10. L28 N42/N42 NEED HELP CHOOSING TURBO!

    Hmm that definitely gives me a lot to think about, I've asked around on some different pages and was pretty surprised to see that more than a few people got some pretty high numbers out of the N42 combo. 350 whp out of a n42 head and block with dished pistons and all, with a blow through triple webber setup! Now that I know it can be done, I want to know what I need to do to make a SAFE 300whp if possible. P90 heads seem like they are getting increasingly more difficult to find (and more expensive). I could run a Water/Meth injection system on my MS2 setup and hopefully have some sort of fail safe for it. I will be running a good intercooler setup and do everything I can to keep the intake temps down. I'd like to install a sensor too just to see exactly whats going on in there. Lots of work to do and money to spend. And I need to find the right turbo still lol CA gas is garbage. Very disappointing that I cant do better at the pump. Again I appreciate the feedback/help/advice! Its been a great help in leading me in the right direction.
  11. L28 N42/N42 NEED HELP CHOOSING TURBO!

    That is what I've read, and one of the reasons I started down this road. And I am apart of the "Church" lol. I have asked some questions regarding this build today to see what I get as a response. And as for EFI I am having a full new EFI harness built for the build using Megasquirt. And definitely running an intercooler and all that good stuff. >click here to see my build thread<
  12. L28 N42/N42 NEED HELP CHOOSING TURBO!

    Interesting.. My build is based off of another member that successfully ran a turbo on his stock n42 head and block. (bonfire79 on zcar.com). My setup is n42 head and block with dished pistons. The current compression ratio is 8.21:1. This is the guide I have been following: http://www.zcar.com/forum/10-70-83-tech-discussion-forum/376338-how-convert-n-l28-turbo.html As for tuning I am having it professionally tuned. But I definitely see your point on being cautious ( I certainly dont want it to blow up) And these motors really seem to be mules! That's impressive to say the least about the 400hp motor on a stock bottom end. I'll definitely up the injectors if that's the case as well. Wouldn't want to fall short on fuel. Also where I live in CA we only have 91 at the most, which sucks! Will I 100% need a water/meth system for this to operate safely? Edit: A P90 head would drop my compression ratio to 7.5:1, even lower than my original target, what other heads work well with turbos?
  13. Absolutely. And alot of my reason with sticking with the L28 build is that its already ready to rock n roll! It just needs a little pep and itll be a fun car(funner I should say!). I'm sure it will get a swap someday but I really am intrigued with the L28 and wanna see what its all about.
  14. Really? Interesting it must be a much lighter material. It sure does take up alot of room! haha worth it im sure though! And I can always swap in a newer motor! With the scarcity of parts for these builds I may not get the chance to do this again! And its looking good! Cant wait to see the finished product!
  15. I couldnt agree more!
  16. It has new tires on it now, I'll have to check what they are. I think the wheels are 16x8 with brand new BF Goodrich G-Force Comp 2's. 225s. They came with the car and were brand new. And I am buying a full harness and kit from softopz so anything that will be needed to get it going he will make sure I have it for the setup I am going for, he's been very helpful. I am also gonna have it tuned remotely to help me get it right. The stock fuel pump has been replaced with a brand new one recently (stock replacement) but I have no clue what it's output is. Most likely higher fuel pressure than stock id imagine. And as for timing I'd assume so (bare with me as im still learning about megasquirt). I know it'll be using the turbo distributor for sure so I'm assuming it will communicate the timing through that.
  17. Believe me I have considered swapping it... But alot of work went into modifying the power steering, A/C and all that stuff to work on this L28 and I would hate to rip all that off and it just fits in the car so well. This motor has been meticulously cared for and maintained by the PO and its just too good for me to pull out. After this motor reaches its limits I'll go the swap route (rb25det probably). That and I feel like someones gotta keep modifying these engines! lol Gotta keep the L28 alive and well. Also want to keep the car as light as possible, and I really like the way a clean L28 looks in the engine bay with a nice megasquirt system installed like some of the pictures on this thread. Someday I'll swap it, but not until I get tired of this one! haha Your build looks amazing btw, do you have any videos?
  18. My goal is atleast 300hp at the wheels. And I''m gonna have it tuned if needed by someone that softopz recommended so I can hopefully save myself from blowing it up haha. For this setup on the stock n42 head and block (+2mm head gasket) I'm not gonna go outside of 6500 until I build the motor more down the road. And like I was saying to turbogrill I wasnt going to add the gauges ill be running but I have added them to the list. If you have any recommendations for a good wideband thats not too pricey id love to hear it. And thank you for the input I appreciate it!!
  19. Thanks! I just figure I might as well start with the turbo now instead of having to revert back to a different setup after I spend a bunch camming it etc. I've looked at many guides on here and other forums and I've joined a bunch of groups on facebook and actually just purchased a turbo manifold for 150 bucks on there! Just need a turbo dizzy. I'll check out that FPR, also did you get a different fuel pump?? And I wasnt going to add any gauges to the list but I might as well add everything, so I updated the list! Thanks for your feedback and recommendations I really appreciate it.
  20. Appreciate the information! Seems like Nissan/Datsun did it right the first time around with these L-series!!
  21. 280z Turbo build

    Any update on this build??
  22. Wow that's pretty impressive! I'll have to keep that in mind for sure. A compression test is the first thing in the works before I do anything major. But my theory on this build is to see what this old L28 can do and if it busts, then I'll swap it.
  23. It was meticulously maintained by the previous owner. So I should be good there. Should I replace the timing chain if it hasn't been done yet? I still have to go through all the paperwork I have on it. Also, what are you using for injectors??
  24. Also I might ask, how much of a beating can the stock L28 handle with a bigger cam and rebuilt head? Is it smart to go with a bigger cam on a stock bottom end motor? Engine has around 117k on it, and has been maintained very well. I''ll need to go through my receipts and see if the timing chain has been replaced as well, as I am thinking that will be my first weak link in the build if anything, but then again I am not familiar with the strength of these motors or the longevity other than what I have been told by others (which is that they are great motors). From what I've read so far, and from your suggestions as well, is that these can definitely handle quite a bit.
  25. I've seen mircosquirt in my searches, I''ll have to look more into that as well. Im keeping the bottom end stock (ie: pistons, rods, crank etc) and having the head professionally reworked with the cam kit: Schneider Performance Spring & Retainer Kit New Rocker Arm Set New Lash Pad Set Schneider Installation Cam Lube Schneider Formula 2 Additive Cam Tower Blockoff Plate Kit + whatever cam I decide to go with! (Obviously if I go with a different cam and they have a different kit available I will go that route, but for now the Schneider kit is atleast a good guideline of what I will be swapping out on my head) I like the characteristics of the Schneider stage 4, but have read that they are not as superior as ISKY or some other cam brands.
