Would 7 psi be too much on stock internals also i was thinking about getting DOHC 2.5 heads with 2.5 manifold, about how much would i be spending on this set up including exhuast i understaind with DOHC dual port i can use a WRX exhaust but i would need a crossmember. Im torn between the two because i learned in school that basically all DOHC means is more to fix when something goes wrong, but i also learned that i would need a little lower compression ratio than my SOHC has which is 9:1 (i think?) to run more boost and be safe
