GT-R turbos on the VQ37

husam2012

Both sides in. Fits perfectly including clearance to chassis, steering coupler and shaft, and even the stock fuel heat shield!
Working on it at the moment so just this for now

I must of jinxed myself. The steering shaft has zero clearance what so ever if i tilt the engine back a little (still not sure how to make it at the right angle without attaching the trans and bolting everything)

Anybody has any ideas? It's hitting the heat-shield bolts at the bottom and even grinding them a little bit doesn't help.

Unless i'm tilting the engine way too far back, then it might clear if i put it at the right angle. Does anyone have pictures of their engine mounted without the intake manifold in place? That would help me visualize it a bit.



These are pictures from the german shop who has built a few 370Z's using gtr turbos. It almost looks like their steering rack is in a different location?




Any ideas/ help would be really appreciated as I'm really out of ideas at the moment :/

Yikes I was worried for you about that steering shaft coupler.
Gamma kit does space the engine up a little bit, no more than you could with the Z1 mounts though. I think the older GTM kits added some kind of extension or something for the steering shaft (Chuck?)... I think the FI kit may adjust the position of the steering rack but not sure about this either (Hotrodz?).

It looks like the first versions of the GTM kits had a similar issue. I found something about it but no details at all on how i would add the extension or move it?

Think some of the OG's with GTM kits should be able to chime in and help you out... You may also consider posting a thread in the FI subforum asking for pictures of the steering shaft modification for the GTM v1 kit ...

While you're at it, you might have a mod move this thread there =) Could garner a little more attention and support from the rest of the FI guys who might not wade around in the general engine section... Good luck man, you'll figure something out. Too skilled!

Thank you again for your support! I was happy today and was thinking i'd have the trans and everything back but there's always something waiting for me :/

Hopefully somebody chimes in tomorrow

Id install the trans and get the engine angle sitting right. Otherwise you are sort of working blind.

I worked on it for about 5 hours today. The darn thing wouldn't slide in. I did use the allignment tool again to check and it fits perfectly so I guess I just need to try it again tonight. Any tricks you use to slide it back in?

One of those plastic "alignment tools"? Honestly I've had better luck centering the clutch disc by eye/fee! than using those tools. There is so much slop in those generally that you can still get the disc not quite centered when you tighten down the pressure plate even with the tool. I'd loosen the pressure plate again, try to center it again and really pay attention without trying to rely as much on the tool to hold it centered.

Of course I'm sure you know that, its probably just you're frustrated with it. Usually what happens. If you called someone else over to help with it they'd get it first try, that's what usually happens to me...

husam2012

I think I just have the engine at a different angle so that's why it's not mating right.

Hopefully it will slide in tomorrow otherwise I'll have to lower the trans and check the clutch/pressure plate again

Thanks for the ideas guys! Hopefully no more problems tomorrow

By yourself? Lot of work. I laid under the trans with a jack between my legs. Put my feet on the bell housing and put the drive shaft in so i could turn and push

That black plastic alignment tool is not the best. Go and loosen the bolts to everything with the tool inside. Then lift up a little on the tool to drive everything up a little then tighten things down before you torque it to the correct lbs.

Thanks everyone for the suggestions!

By trying the tool again, it seemed like it didn't want to go in smoothly so i redid everything and i think it slid in now! There's still about a finger gap but i believe i can just use the bolts to bring them together now?

Ran out of time today so will start working on it again tomorrow morning hopefully!

Finally installed it in. Looks like I have to do the steering modification similar to GTM's. Not horrible but just an extra step.

Nice to see that it is going to work out after so much effort!
