VQ37 Engine Best VIN | Engine build for TT
 

Hi Forum,

Going to start an engine build for a 2014 370z Nismo. Actually haven't found the Z yet, but getting an engine and wanted to know what are the better VIN letter codes I should look for.

My numero 1 is the gallery gasket issue, but I have see. Many different variations of the VQ37 based on this VIN 4th digit letter.

Shooting for 750wHP. Will be a forged short block. Valve train seems to be pretty good on these from what I read.

Headgasket issues will be your problem. A built short block with a closed deck may or may not hold. I blew mine daily driving at 718hp. An open deck will not hold. That is what I had. You need to do lots of searching and reading on here. It is a major problem with the VQ37Vhr platform. Lots of misinformation is out and about.

You can read all about my trials and tribulations here. It may take you a week or two to read it all. Lots of information.

Yeah, i'm 6 hours in your thread. Lowering my expectations a bit now! Trying to build a street / HSDE Z that is a couple steps above my current 350z HR Nismo A-A S.C. setup.

I figured with Forged pistons/rods/multi-layer headgasket/ and upgraded oil pump/twin pump fuels return system was basically the major items... minus the twin turbo kit.

My budget is ~5-6K on the motor build, 10K on the twin kit. I have a full lift at home so install labor is what I would be saving. LSD, clutch, exhaust as other supporting items.

Get a Fast Intentions Twin turbo kit and run the stock block while you save for a proper motor build. You will spend you motor money on supporting mods.

Do you have final dyno numbers on your car yet?

Yeah, I posted them.

I haven't seen your e85 numbers.

Yeah you did. 900.54hp at 25psi of boost.

For some reason I remember seeing it. Was that in the same thread that you were asking about Ben's sc soho build?

LOL, NO. It is my thread in the Forced Induction section. See link above. Have you have been hanging out with Cheech too much lately?

I wish. I went back and found it. That was the day I was prepping for my endoscopy and colonoscopy the next day. I was pretty out of it. I should have made a call to Cheech. :icon14:

Rusty, Aka Chong, would have answered. LOL

I'll keep that in mind for any future needs :tup:

Plan is to pull the stock motor and just put it in storage.
