many basic questions

[sting0004]

Should I get a 3 inch exhaust and port my O2 housing or get a 2.5 inch exhaust with O2 eliminator? How much HP and Torque gains can i expect from either of these (they are both turbo back exhaust). If i am expecting to run 17 psi boost in the future should i get stock 1g blowoff valve or do i need an aftermarket one? Are any of the cockpit adjustable mbc actually worth it, or should i just get a regular mbc? Thanks for your help! -Matt

i would go with the 3" exhaust and porting the o2 housing, if you where planning on going with a bigger turbo at some point. and i believe the 1g bov would be fine as long as you crush it. and i have not ever used a cockpit adjustable mbc. hope this helps

Yeah, I would also reccomend getting the 3", and porting. Cause if you need to eventually, you can get a hogged out O2 Housing anyway.

I've read a bunch that the 1G BOV is good enough for 17 psi, so I'm assuming it'll be fine for ya (but I haven't ever turned up my boost past 15, so I don't know personally)

About a cockpit adjustable MBC, why even bother? If you can run a good level of boost, why would you ever want to turn it down? Just step on the gas pedal less if you really need to. Personally, I would say they're not worth it at all. The only reason you'd need to adjust it is if you were using Racing gas, but you'll probably have your hood open doing other things anyway... so yeah.
