Vg30e
 

I know that it depends mostly on the block's endurance, but how much power can I get out of a VG30E, without a turbo, block bore out, or a bottle? It's not that I hate turbos, just the opposite, but it doesn't have a turbo from the factory, and I want to keep it as stock as possible. The main problem with turbos is having the gauge on the support beam would be less than ideal, considering I want it to be a nice daily driver, and not for racing.

I've already been told that it won't reach 300 whp n/a, and more or less that wanting to leave it n/a is a fool's errand, but anything is better then the 160 at the crank.

This should probably moved to performance.

With about $5k in parts, you can get around 200hp at the rear wheels without nitrous.

But if you're really interested in making power, you won't stop from going forced induction.

The only difference between a VG30E and VG30ET block is the compression ratio because of the pistons.

that would be with a bore/stroke though right. he wants it without bore/stroke or nitrous. either way, its a lot of money for basically nothing. for what you spend to get any worthwhile gains from a vg30e, you could buy and modify a factory turbo z31.

what you want is a contradiction. more power from the vg30e, but basically stock. not gonna happen, sorry.

So, I'm screwed three ways to Sunday.

pretty much, yeah.

my suggestion is just add bolt-ons I/H/E and some high flow cats or test pipes.

It wont make the car much faster but i will give the car a better sound and if you are not happy with those gains you wont be happy with an NA car ever unless you can afford limitless R&D.

I would swap pistons and throw a new metal HG and run a 46 trim t3/4 at 10psi that should give you all the power you are looking for. That with a 3" DP and high flowing exhaust and proper fuel tuning you should easily be in the 200+ hp range.

You don't need to swap pistons or use metal head gaskets to turbo an NA motor in the Z31.
