It's a known fact that tuner toy rods and vitara is the cheapest build and is good for 400+whp

You need to stop seeing that "some people" can make power on high compression and such and stick to what is proven.

Another thing I have recently herd that you might want to look into is higher PSI vs less retardation. I'm not sure on the specifics but I'm not looking into a turbo atm so thats all the info I have.
