GT-R turbos on the VQ37

You drive to a higher or lower altitude and the tune better follow suit, and the air/fuel mix better change as needed or meltdown is not far away. And then I think about the factory turbo'd cars like the Sub'y WRX Sti (up to last year) and the BMW 335i that have had big problems, requiring engine replacements. All the factory R&D dollars put into those models weren't enough to prevent big reliability problems. And you are going to build up a system with various turbo components from other models? Wow, my hat is off to you for your courage!

Then there is the consideration of selling the car in the future. We've all read that the resale value on a highly modded car will plunge. Nobody (or very few) want to buy a modded car knowing the stress placed on the motor and the likely or perceived driving style of the owner (balls to the wall). You could always remove all the performance mods and try to sell them at the time of sale I guess. Good luck on getting back much of your investment.

I think the biggest bang for the buck would be a 100-shot NOS system with tune. But again, you takes your chances the delivery system stays accurate. But like I said.... I'm old (66 )

I read the line, "I need the car to go to college" and immediately BIG flags went flying up.
The strong possibility of having to walk and watching money disappear like a bank robbery if things went wrong, is just not something I would ever attempt or suggest to anyone in that position.

Now, someone with deep pockets, other cars in the stable to use if something goes wrong, that's another story.

I followed the online forum TwinTurboNet for the 90 - 96 300ZX's for years when I owned a 1990 300ZX NA (sold it after 18 years of ownership when I bought my present 370Z). There wasn't a week that went by that a newbie would post that he'd just bought a 300zx NA and wanted to turbo it.

The answer that was thrown back every time from the forum membership, was to sell the NA and buy a twin turbo. Don't even try to do a turbo setup yourself. If you want a turbo car, .... buy a factory turbo car.

But, its your car, your pocket book, its a free country and you are permitted to do whatever you want short of breaking a law. So, should you want to go ahead with your modification, its your decision alone. But its not something I would consider wise, or ever consider doing myself.

If you know what your doing then go for it! The 370z wasn't turbo'd from the factory obviously, but that doesn't mean it can't be turbo'd without making it unrealiable. The compression ratio for the vq37 is a bit high for boost, but if you get a good fuel setup, maf location in the right place, and a large intercooler you will be just as reliable as any TT kit on the market. Just don't go over board with the power. I've seen videos of the vq37 making 700whp on e85 (don't even think you could make that much power with GTR turbos) but for a daily driver just keep power levels on the lower end. I'll be keeping a eye on this one!

Good Luck

I was wondering about this.. Do you guys think there would be any interest in a group buy for the adapters when i get them perfected to fit without any other modification?

I have the intercooler and piping figured out already, just not sure how to do the down pipes yet! If anybody has any ideas, let me know!

Mind you that would include intercooler/piping/brackets, oil/water lines, and some kind of downpipe or exhaust adapter to set flanges in a factory location. If I wasn't TT already I'd buy it in a heartbeat.

Think just the adapters would get done interest as well.

Anyways, I got the motor out yesterday from the top! I didn't want to drain the AC so I just lifted it without the transmission.


One thing that I feared is I have to make a driver side slim motor mount bracket, anybody know a company who makes them? I contacted Gamma but they are very pricey for just a little bracket







If anybody knows how to make a slim driver side mount bracket or who sells it, please contact me asap!

Z1 sells some urethane motor mounts that are smaller than the OEM mounts... Not sure about the brackets though.
