hey i got a 2000 si and so far i got a greddy exhaust greddy headers skunk2 intake manifold and and injen cold air intake where should i go from there i don't have the money 4 a turbo or a supercharger i just would like 2 know i am in iraq right now 4 another 5 months so i got a lot of time 4 advise thanks 4 the help cause i need it all help would b great

 

Do all the ins and outs. A high flow cat, throttle body.

 

Iraq huh, I was there almost a year ago (AF)... Definately look into a set of cams and some computer work (ECU).

Stay safe bro

 

word ok then what is a good brand 4 hi flow cat and what kind of throttle body like what MM and 2 polo i am 2 in the (AF) out of little rock thanks 4 the help guys

 

Random technologies makes a good cat. Not sure on the MM though, Ive used an edelbrock peice that was good to me.

Polo nailed it too with cams and computer, I forgot about that stuff. Look into some Skunk2 stuff and maybe even springs and retainers later.

 

yes will do that what computer stuff should i do also whats up with injectors

 

your stock injectors will support at least 50 horses over stock, so save that money for now. dont worry about ecu stuff for now, at least until you find a good dyno, or drop the dough on a wideband O2 sensor to do your own tuning with a piggyback like the Apexi V-AFC.

 

ok what is the apexi v-afc and a good web site to look at it

 

search that on ebay. its a computer that lets you change the fuel maps for your car.

 

yea i would check on ebay but they got filters on these computers out here so i can't get to it any other places
