Ok H22 engine swap with a turbo installed would be like 6k maybe? Maybe less, maybe more. That, with intake, exhaust, high flow cat, pullies (all bolt-ons)... would already put you at almost 300 whp. Your car would run very fast.

Suspension would be from 700-1200 dollars if you did it right.

I don't like Dodge, but that is just me... either way, have you ever thought about the WRX? The new WRX (non-STi) will only be a couple (1-3) thousand more than the SRT-4.
