a vg30et is a good motor, personaly I would rather have a drop in than a v8, I like v8s but it takes money to get one of them fast, not that a high hp vg is cheap but I estimate 3 grand or so, I dont know. I have my stock engine at like 14psi and I keep up with a good bit of stuff.
gut the intake plenum, t3/t4 turbo im not sure what PSI to run but 15 to 20 should be fine for around 450hp, fuel management system, bigger injectors, fuel pump, bypass valve, better maf, a transmission and half shafts that can handle the power, I am not sure if an open r200 can handle a lot of power as far as having radials or slicks on it HEHE, 3 inch downpipe and exhaust, high flow cat if you have inspections, we are in SC so no inspection. where do you live? I am in Rock Hill(near charlotte)
