GT-R turbos on the VQ37
 

Passenger side almost done. Just waiting for the water line fittings so I can install them before I put the engine back. Driver side is almost done, just doing a small modification so I can use the OEM inlets on both sides.


Here's an idea of how the adapters look like!

I might have missed this, but just to clarify, you are using the STOCK header to the GTR turbo, and not using the entire turbo/manifold setup?

Keep up the work!

He's adapting the GTR manifold and turbo to the VHR.

Correct. Both the manifold and the turbo fit using my adapters. Even the GTR inlets do fit but the driver side requires some grinding to the motor mount bolt.

Clearance is tight though. I'm running the urethane motor mounts just so i don't have anything contacting when accelerating.

I was wondering if anybody knows this.. should I use a crankcase breather filter or route them to the OEM GTR inlet pcv pipe?

I've got mine routed to my turbo inlet pipes... Looks like it would be convenient for you as well!

You could do ether. Breather would be easiest. Or you could could run a catch can between to keep oil out of the turbo and have vacuum in the crank case

run a breather or a catch can for that hose location.

I feel like there is some confusion of which hoses we are talking about?

I assume that's the fresh air inlet (that normally connects to the OEM intake pipe), correct?

If so, you would either put a breather there or connect to the turbo inlet pipe (where it effectively uses the intake filter instead of its own tiny breather filter).

The hose off the PCV valve that goes to the intake manifold should remain the same, or you could put a catch can inline with it.

Yeah I was confused at first by connecting that 3/8 hose to the inlet but I figured that goes to the intake manifold.

The breather hose is 5/8 so I bought a 5/8 to 3/8 reducer and ran the breather hose to the GTR location (the metal hard pipe coming out of the turbo inlet)

Sounds like a good solution! Might as well make use of what Nissan gives you with the turbo inlet =)

I'm really enjoying your progress.

Thank you! I can't wait to finish and go ally have a car as fast as yours haha


Right now, I dropped off the turbos to the machine shop to get the manifold ports matched to the adapters. There's a slight lip due to the adapter angle. I figured might as well do it since it's cheap while it's out and might get me an extra 10-20 whp.

I'm not excited for this. Wish I was doing a boost build now

Are you in too deep to switch gears? If there is eventually an intercooler kit to go along with these adapters, what comes out of this thread could be a real game changer in terms of TT cost of admission. Probably even cheaper than the GTM group buy pipedream. Though something like that is probably a ways out.. and I don't know what husam's plans for this design are.

Not really. Going to be placing my order on a billet crank here in the next few months. So I have till then to decide. I not so much into power but want something reliable for constant abuse at the track.
