intake : short ram vs. cold air? Why? Difference? Does it effect the ECU? Recommendations?

exhaust: turboback vs. catback? Why? Difference? Does it effect the ECU? Recommendations?

suspension: coilover's: Recommendations?

Coolers: FMIC? Recommendations?

 

Intake: keep the stock one, its your best bet unless your pushing a lot of power

exhaust: turboback is a larger section which includes the catback. turbo back is everything from the turbo to the end. catback is from the last cat to the end. your real question should be catless or catted.

suspension: if you have the money and the need, get the coilovers.

intercoolers: as with the intake, you only really need a FMIC if youre pussing a lot of power. I had a buddy that put a giant FMIC on his STi and the turbo lag was so horrible that the turbo didnt spool up untill it was almost time to shift. stock TMIC will go far, no real need to change it. If you upgrade to a giant turbo, then you might want to think about a FMIC and an intake.

also, you'll want to get an engine management system (Cobb, Ecutek, something like that)

 

oh as far as the exhaust question goes.. should the tuboback be catless or catted? and whats that mean hahhahha. which gives you more horespower. i'm guessing catless is "louder"? and catted is silenced im just throwing my 2 cents out there.

Wow, I guess everyone's gotta start somewhere huh? Please use the search button.

 

get cold air intake after u hav alot power, cuz if u get cold air intake rite now, ull have more turbo lag, the longer the pipe the more turbo lag.

 

^CAI isnt needed at all, the stock air box does a great job. to answer that question about the cat...

catless: has no catalytic converters, which means your car will not pass smogs tests, and will be louder

catted: if you put in high-flow cats (which can be pricey) your car will pass the smog sniffer test (examine the exhaust for polutants) but will still not pass the visual test. the stock cats will rob you of a lot of power, but a aftermarket high-flow cats will only take you down a few hp from catless

 

Short ram would involve less worries in this situation, and/or if you're running a front mounted intercooler.

 

CAI is useless - you run the air thru an oven/turbo! Reason to have a shortram? When your piping for your front mount gets in the way.

 

CAI will lean out almost any turbo'd car, and could cause SERIOUS problems. rich cars waste gas, lean cars blow engines.

crap, I'm starting to sound like a NASIOC'er

 

yeah i used to be a search natzi when i doing most of my posting over at wrx tuners, but the thread allways degenerated into a repeat of some other thread so i just stoped. if you cant beat em....
