GT-R turbos on the VQ37

husam2012 · 03-12-2018, 05:26 PM

I'm pretty much done and would of had the engine back in if it wasn't for the stupid auto crank spacer. Still trying to figure that out and hopefully engine will be back in before the weekend.

Meanwhile I finally finished a few things on the car itself. Fuel pump basket modified and walbro 450 installed along with fixing a few broken bolts here and there on the chassis. Also finished installing the steering rack brace and the subframe brace is finally back on!

Nice!

What are you planning to do with the drivers side oil feed? Reuse the pressure sensor adapter?

Yes, I'm using that adapter to feed the driver side turbo and an oil pressure sensor.

Here's a few more pics for you guys

Also, I'm trying to run my new exhaust setup very similar to this one. Hopefully I can figure out someone who has something similar for sale.

Engine's finally back in and I cranked it before installing to double check leaks and oil pressure a s everythings good so far!
Going to the exhaust shop this week to make a few downpipes then after that it's time to figure out the location of the inlet filter and tune shortly after

Any suggestions you guys have?

Fabbing the downpipes has taken longer than I had expected but hoping it's going to be done Friday. I'm also expecting my ported lower and upper manifolds today along with my injectors!

For anybody that was wondering, the passenger side oil source did turn out to be functional as I tested it by cranking the engine over and checking the turbo drain line.

Here's a couple teasers

It seems like my lucky is always bad with this car. Tried to start the engine and it was acting weird. Upon a closer inspection it appears that bank 1 has bent valves or some funny business going on. 220 compression on bank 2 while bank 1 varies between 105-130.

Any ideas? I'm going to hope that the timing is off and will retime it tonight but if it's bent valves then it's time for another motor *

glad to see you in the home stretch

FACK

did the motor come with any kind of warranty?

jmroy6 · 04-11-2018, 03:14 PM

Did you re-time the motor since you bought it? otherwise id get your money back for buying a lemon.

Never touched the timing chain. I did take off the cover as it was very very corroded and switched it with mine.

I hope i can get a refund back. It really sucks how far I got only to be set back once again

..

I did retime it today incase the timing was off and redid the leak down test only to have it fail it with flying colors. Could it be that I'm missing something? It's very confusing honestly.

It's very frustrating to do everything perfect only to end up here. I'm not sure where to go on from this point with this build.

Here's a quick time lapse of what I did today. Phone died when I took the chain off and retimed it.

jmroy6 · 04-12-2018, 11:43 AM

id recheck timing for bank 1, maybe its off a tooth or two? Otherwise you have bent valves/bad rings.

this is so disappointing to see, keep us updated on what you find!

So I learned a new thing yesterday!

Engines that sit for a while get their rings stuck sometimes and just running and revving the damn thing makes it fix itself sometimes.

After spending 8 hours taking the cover and oil pan off and retiming the engine only to have 80% leakdown still, I almost gave up and called a local junkyard to deliver a new engine to me. At the last minute I decided to put the cover back on and just start revving. 5 minutes later I redid the leakdown and compression and every single cylinder has 5% leakdown and 220psi

I hope this is the last of my funny luck with this car.

Nice, isn't that called an Italian tune up or something?
