GT-R turbos on the VQ37

Finally some free time today. I think I figured out why bank 1 was richer/maf voltage lower.

It looks like this clamp wasn't tight enough since I could pull move it with some force. Tightened it to as much as I could without breaking it




Also some more pictures since I don't think I've posted these before



Steering rack shims/ spacers



Steering shaft clearance is about a finger width now. Shouldn't be an issue at all



Passenger side. Excuse the messy downpipe haha



Tidying things up and looks like I have a small pinhole in the wastegate line! Maybe that's why it goes up to 12 psi. I hope so atleast





Also, thanks for the idea whoever posted it here. I tested the wastegates and they open at the same time but the guage isn't very accurate I think since it takes 20 psi to open it all the way. It starts opening around 4-5 psi but the guage is off since it's a cheap $10 pump





Edit: just did a pull after making sure there's no boost leaks and it's still at 12 psi and even 13 :/

Good news is my new injectors are working perfectly WOT (60% duty cycle now)but a little weird while idle which is understandable.



Notice the boost at 3000rpm
