https://forums.hybridz.org/discover/HybridZ - All ActivityenTrickflows are a great choice. I have a turbo 351 so not a direct comparison but when I switched from GT40s to 11r 190s it made a massive difference. Unrelated to the engine. I weighed my stock 280z door today. Its gutted so I can paint them. so no glass, regulator, handle, lock, hardware, window frame ext. just a empty door shell. 34lbs.Mon, 20 Apr 2026 13:53:24 +0000Axles finally came in. Didn’t have much time this weekend, but cleaned the top of the motor and bolt holes and got one head installed.Mon, 20 Apr 2026 01:10:59 +0000If you donate to the site you'll then be able to post FS threads. That said, FB Z groups are the big thing now. Craigslist and ebay also still work, but marketplace and group posting get the most eyes on it in my experience.Sun, 19 Apr 2026 23:02:00 +0000Hey Y'all, Right as COVID hit, career, kids, shutdown, and just about everything else took over and I essentially stopped all work on my car, forums, and deleted social media. Six years later, life has calmed down and I find myself with time, motivation, money, and a little bit of energy to work on the car again. The parts hoarding is done, now I just need to work on it. But the state of internet forums/groups has me completely baffled. 1) I have a ton of OEM and aftermarket parts to sell, and aside from Craigslist and FB Marketplace..how do you do that? Like, how would someone on the other side of the country know I have a bunch of parts to sell for cheap that I'll ship? I can't create a parts FS thread here, and we all know that unfortunately forums just don't get the visits they used to. 2) how do I engage in non-facebook Z chats/community? IS there one?? 3) Generally wtf has happened and how do y'all manage it being a Z / auto enthusiast in the current landscape?Sun, 19 Apr 2026 15:58:50 +0000It's quiet compared to Flowmasters. You can converse well around town and on the highway.Sun, 19 Apr 2026 14:38:37 +0000Fastest s30 IRS timeslip is now 8.38@163.9 mph in the 1/4 mile. Shown are Terrys previous 8.42 timeslips in the same car from different days.Sun, 19 Apr 2026 07:37:28 +0000Sat, 18 Apr 2026 06:57:13 +0000This is what I put on mine.... https://www.dynomax.com/mufflers/ultra-flo-welded-mufflers/ultra-flotm-welded-centered-centered-598.htmlFri, 17 Apr 2026 21:30:01 +0000I have been having a flowmaster hushpower pro 3" in and out 13012100 for the last 10 years, and it is loud and has so much drone on the hwy. I am looking for something quiet (er) and no drone. What are yall using on your swaps that is quiet and fits in the stock location on a 280Z?Fri, 17 Apr 2026 14:07:19 +0000Hello hybrid z, its been so many years since this thread. Im now 46 years old. After reading through my build thread it brought back so many memories. I still have the car (I'm never selling it) it has seen some upgrades through the years gtx3582r turbo, injectors, standalone..etc. the car is still running like a champ and I have never been inside the engine all stock factory toyota. What's most amazing is how reliable the car has been...I think the only major problem i had is when the stock ecu went out.. Things I would like to do in the future are, totally new wiring throughout the whole car, all new fuel system and lines, stainless exhaust system, new dash and seats, new rear suspension setup.( i did the front a few years ago). Reflecting on this build also brings to light how expensive everything is now...in 2008 I paid $2000 for a 1jzgte and r154 trans...today that would cost 6k or more...my z was only $600 running and driving..now, that is about 4k or 2k for a z with trees growing through it... any kind of build like this now us easily 10-15k from the jump.. and thats not counting what you have to upgrade and replace because the car is 50 years old..lol It was and still is a awesome journey! Currently projects (nothing ever changes😊) 84 chevy c10 super charged 4.8 ls engine swap....should be done soon... 84 rx7, s5 roatry engine, ida weber, wide body, 10x17 all four corners😉...Fri, 17 Apr 2026 13:55:28 +0000I put a 3" in and out hushpower on my LS Z thinking it would be quiet. Its the only thing I dont like about the car, its loud and very droney on the hwy. Im trying to find what would be the quietest muffler that will fit in the stock location, I dont care if it takes a slight performance hit at this point to make the car more enjoyable.Fri, 17 Apr 2026 13:37:31 +0000L6 3.0 Rebello build with MilkFab Crankfire on the required 280ZX front pulley. The ZX pulley has a "B" size (5/8"width) for the AC and the normal "A" (1/2") width for the alternator and water pump. The car is street only and in Houston, TX. I have the complete AC system that I have used for close to 30 yrs and all I really want is a Sanden clutch for my compressor. I will spring for a compressor if it has the right width belt and can fab my own brackets if needed. Sanden won't answer e-mails and most of the parts sellers don't have the answers. Looking for anyone that has solved this issue.Wed, 15 Apr 2026 18:07:31 +0000I have a bunch of them from diesel maximas and some did not have the wings. Now they could have been replaced with Gas engine pans sometime since 1984. For drag racing you may need to add at least one baffle because the combination of front lifting upon launch and the acceleration of the car can actually nearly empty the pan and submerge the rear half of the crankshaft in oil. I didn't feel good about what was there from the factory.Tue, 14 Apr 2026 19:09:17 +0000Today is the first day in over a month with no problem. No slowdowns on other sites. Just left and came back with same problem - took over 1 minute to load, 15 seconds to go to particular forum.Mon, 13 Apr 2026 13:16:51 +0000it didn't occur to me that it could be something specific to this page but mine has been painfully slow for at least a month. Just assumed it was something to do with my internet.Mon, 13 Apr 2026 00:36:17 +0000Seems fine to me. Must have just been an intermittent issue.Mon, 13 Apr 2026 00:15:50 +0000Part 11- trial Fit of the 370 Rear Drive Sewction into the 260Z. In this episode, the Car is finally on the ground for Rear Suspension construction. Since they are using a Fiberglass Hatch Delete section, there will be very little space for anything else but a Fuel Tank Cell. the major problem is time to finish the car as they are not even at the half way point of the build. The craftmanship truly amazing as they solve problems with building a one of kind vehicle. .Sun, 12 Apr 2026 09:04:57 +0000Been 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.Sun, 12 Apr 2026 01:07:35 +0000What is wrong with the server setup on the hosting site that causes such slow response times?Sat, 11 Apr 2026 18:37:50 +0000Front end got tidied up quite nicely and I made new brackets for my intercooler. The drier clears, but I'll have to place the trinary switch on the #6 line instead of the drier. No big deal, but I wasn't able to make the rest of the hoses while I was here. Used on the threaded holes for the original airbox for one of the top brackets, and an existing hole made by the previous owner. The brackets on top aren't supporting weight, just preventing it from tipping forward or back so it doesn't torque on the lower brackets and bend them. Only downside is the brackets look slightly lopsided but the intercooler is centered! Took the car to get aligned and they told me there was play in the steering shaft from a cross threaded bolt. Looks like the end wasn't all the way in and the bolt had never crossed to the threaded side. I loosened everything, chased the threads, and got everything tightened up. Also added one of the missing trim pieces. Looks much nicer. The car as a hole is feeling pretty good, and nearly everything is great. I'm just at a loss with the rear end. I know it'll probably help slightly when I go to the 3.54 rear and everything is rebuilt but there's just this persistent vibration. Flipping the driveshaft 180 somehow solved most of it, but I still get the occasional buzzing and it's driving me crazy. I'm about ready to go back to the stock control arms, oem spindle pin, stock mustache bar, and a kameari mount on the original front diff crossmember. Everything on the car just feels so great except for the rear end buzzing or squeaking. So much of the car is damn near perfect that the small issues like that are a distraction from enjoying it as much as I could. Alignment rescheduled for today, so we'll see what they find or if it solves my problems.Fri, 10 Apr 2026 19:14:58 +0000To wrap this all up, it made 308hp 358lb/ft at 4510RPM 17PSI. Power was climbing the whole time, but it ran out of injector at 4500RPM so I limited all runs to this. More power than expected. Plenty of power for the street, but to be safe I will step up to bigger injectors.Thu, 09 Apr 2026 18:58:33 +0000They are super light, I’ll get a weight on the shell this week and share, and in a few months when I get around to installing them I’ll get a full weight with windows/hardware.Wed, 08 Apr 2026 12:19:30 +0000Those are incredible. I'm with Mitchel on needing to know the weight difference. You gotta put them on a scale for us. Very interested in fitment and your thoughts along the way. They look like they allow for roll up windows and factory door handles too. very nice.Wed, 08 Apr 2026 11:44:46 +0000I would love to see a full weight comparison between the original and carbon fiber door. I know from lugging my 280z doors around that the factory doors are quit heavy.Wed, 08 Apr 2026 08:57:16 +0000Carbon fiber door and door cards came in, these things are super sexy 🥰Tue, 07 Apr 2026 23:29:59 +0000
