I have no idea how hard the DET motors are to get. A DETT would prolly be easier, and emissions legal. If you want to do something real unique, put in an RB26.

$4k for a motor that puts out 270hp?

Do you realize what kind of power you could get out of the VG30ET with $4k?

Yes. I read that. Did you know that with a $10 boost controller set to 12.5 psi, the VG30ET puts out 270hp?

So why do you want to spend $4,000 to get the same amount of power that the stock VG30ET can put out with only $10?

edit: Also note I said VG30ET, NOT VG30DET.

If your goal is to do something different, then by all means, go for it. But if your goal is to get a bunch of horsepower, the cheapest and easiest way is to stick with the stock block.

Go with the DET engine. Unique one-off setups are the coolest. How many Z31's here have a DOHC setup here? If you have the $$, it sounds like it's worth it. A factory turbocharged VQ would be VERY cool. I've never even heard of a stock turbo VQ. If it comes with 270 from the factory, spend that $10 on a boost controller (well, more like $50 for a good halman) and make 350. I'm guessing it's a single turbo setup, so upgrade that, intercool, cams, and because it's a VQ, there should be just as much, if not more, aftermarket support for the engine. I hope you can weld, there's going to be a bit of fab work involved.

if you put 12.5 psi on the stock setup wont there be detonation, it doesn't have a stock intercooler.

Some do. Most don't. I don't have a problem with 91 octane.

I ran 16 psi non intercooled with just a little detonation.

Engine lasted 6 months- 12.9 @ 108

Surprised the hell out of a lot of C5's and 03 cobras.
