I'm still checking everything over! Bumper won't go back on until after the dyno tune so I can make sure there's nothing leaking etc

I drove the car around 50 miles on the base tune and so far so good.

I will be checking the car over on a lift tomorrow (friends shop) just to make sure that everythings good then i will be going to the tuner for more street tuning.

Default GT-R turbos on the VQ37

Turns out that the wastegate spring pressure is 8psi.. so I'm just going to skip buying a boost controller for now.

Got my boost gauge, oil pressure guage, and maybe going to order an AFR guage just for safety. Car runs awesome midrange but still can't go WOT yet.

AFR shouldn't be a maybe. I'd also add a fuel pressure gauge to your list.

I don't run one... but you are probably right. I am just kind of anti-gauge. So I just did boost to make sure I don't lose a wastegate line or something and don't worry about the rest. I don't have the attention span to pay attention.

I will get one as soon as i can afford it! I promise guys

One thing that worried me after finally fixing that oil pressure problem is that the car smokes on deceleration. I figured something must of went wrong as the car was ran without oil pressure.. Anyways, that was running cheapo walmart 5w30 oil.


I just did a final oil change with M1 0w40 and a good quality filter along with fixing a slight kink in the oil return line and guess what! no more smoke and it doesn't stink as i drive around anymore

Now i'm just waiting for the tuner to schedule the damn dyno! He's been telling me he's busy for a week now..

Finally got more street tuning yesterday and did a few WOT pulls. I don't think I've ever been in a car faster than this to be honest. Only problem so far is that it's running too much boost (assuming map sensor is accurate) so my fuel injectors aren't big enough haha
It spools to 8psi by about 2800 and then keeps going to 12 psi at 4k and stops climbing there.

those little turbos are spooling hard on you...

Some options off the top of my head, in the order preferred:

1) Get more fuel and make more power =)

2) See if you can reduce the tension on the wastegate springs

3) See if the wastegate flapper is large enough to port the wastegate out for more flow

4) Make your exhaust more restrictive - what exhaust are you running from the turbo back?

Aside from that, you can also consider the far more expensive options of plumbing in external wastegates or upgrading to much larger turbos =)

I'm sure someone smarter than me will chime in with more options as well =)

I wonder if your tuner can pull some timing to keep it from spooling so much on you? That is pure speculation as I do not really understand the technical aspects of tuning in this scenario.

Also, can you tell your camera holder that landscape is superior to portrait? =)

And...clarification on #2 above. Does it spool to 8psi then slowly climb to 12psi at redline? If so, wastegate tension won't help.. as you are just out-flowing them even with the flappers wide open.
