LamboZ Posted September 11, 2006 Share Posted September 11, 2006 Im trying to make room for my downpipe on my L28ET, but i can't seem to find any more room. I know the L6 is already slanted some bit, but I was wondering how much more can we slant this engine? I know doing this will move the shifter some, and I would need to do some work to the mounts. If i slant it some more, will this cause any problems internaly? Any info would be great. Quote Link to comment Share on other sites More sharing options...
EZ-E Posted September 11, 2006 Share Posted September 11, 2006 What Z are you working on? 1st gen or Zx or ? You cant fit if you want though it isnt needed a 3 inch down pipe on either. It just takes time and patience. Quote Link to comment Share on other sites More sharing options...
LamboZ Posted September 12, 2006 Author Share Posted September 12, 2006 its a S30 Z. this isnt your run of the mill type L28ET setup. downpipe is 4inchs and the exhaust manifold takes up alot of space. so thats why the need to slant it more. so anybody?

johnc Posted September 12, 2006 Share Posted September 12, 2006 Oil level in the engine and transmission will change. Possible clearance issues with the steering rack/oil pump. Possible clearnace issues with exhaust manifold and brake MCs. Possible clearnace issues with the alternator and the steering rack/frame. Clutch slave cylinder lines might have to be extended. Electrical to the starter might be too short. Basic driveline alignment will change and have to be corrected. Quote Link to comment Share on other sites More sharing options...
v8dats Posted September 12, 2006 Share Posted September 12, 2006 how about posting some pics? would love to see this setup Quote Link to comment Share on other sites More sharing options...
z-ya Posted September 12, 2006 Share Posted September 12, 2006 I would be concerned about the oil pickup under hard cornering (oil starvation), and the transmission being properly lubricated a the new angle. Making the down pipe smaller is a lot easier than changing the engine angle. Anything larger than 3", even on a high horsepower turbo motor is very close the point of diminishing returns anyway. IOW, you probably won't gain much power with a 4" downpipe over a 3" one. Quote Link to comment Share on other sites More sharing options...

Brake MC's are inside the car, so that wouldn't be a problem. Alternator won't be a problem, im running a custom mount and shorter belt. Clutch slave cylinder lines won't be a problem. Electrical is all custom, so not a problem. Now..... the driveline alignment is the hard one. The tranny/shifter angle would change and I know ill need to fab up a new tranny mount, I have to make one anyways for the tranny I am using so thats not that big of a problem. oil pick-up. I was going to cut it and re weld it to the angle it was at before. That should be okay, correct? I was only going to slant it maybe another inch or 2 towards the passenger side. Thank you for the help so far. Quote Link to comment Share on other sites More sharing options...
slownrusty Posted September 13, 2006 Share Posted September 13, 2006 Go to the Fabrication section, I have pics and a pretty good thread over there talking about tilting the motor...I decided against it in the end. Yasin Quote Link to comment Share on other sites More sharing options...
Guest Cronic Posted September 13, 2006 Share Posted September 13, 2006 I am assuming you have a turbo header instead of just a stock-like manifold on there. If you're insistant on having a 4" DP - you might consider redesigning the manifold, or at least moving where the turbo connects. Perhaps go with a side exit exhaust, or something outside through the fender. Clocking the motor is not something you want to do IMHO. There HAS to be another way. Even if you're running a slightly smaller downpipe. What turbo is on the car? Quote Link to comment Share on other sites More sharing options...
Tony D Posted September 14, 2006 Share Posted September 14, 2006 Use a thick enough Engine Plate, and the only thing rotated will be the engine, you can mount the tranny straight up, to the Engine Plate. Then all you need to do is alter it to relocate the starter. The Electromotive 280ZXT was laid over at almost 30 degrees towards the passenger's side of the car using dry sump, and allowing a long curved runner intake manifold. What, only $40K in fabrication, nothing big....... LOL It would probably be easier to relocate the driver's side using Fairlady Z parts to RHD, and really open up that side of the car. I know RS Okinawa used 5" exhaust on it's Twin-Turbo Setups in the Late 80's. But such is the advantage of RHD.... Quote Link to comment Share on other sites More sharing options...
greenmonster80 Posted September 14, 2006 Share Posted September 14, 2006 I agrre with TonyD. Just convert to a RHD. Have a nice setup that isn't patched together. Looks bad ass and sets the car apart even more. BTW I was at RS 2 days ago. They have really changed over the years. No sports cars what so ever....

ezzzzzzz Posted September 14, 2006 Share Posted September 14, 2006 If you're hell bent on the 4" tube then maybe oval tubing will do the trick to gain needed clearance. http://www.drgas.com/store/home.php?cat=8 Quote Link to comment Share on other sites More sharing options...
LamboZ Posted September 14, 2006 Author Share Posted September 14, 2006 Im running 4in oval tubing, but its harder to use the oval tubing right off the turbo, makes for even less space. i have 4in oval tubing starting right where the tranny starts, so im going from reg 4in to oval at that spot. Turbo is a GT42R Quote Link to comment Share on other sites More sharing options...
