i own an 02 Civic Si, and i want to know what i can do to it without hurting the reliability, its got 89.000 miles on it so keep that in mind....any suggestions would be great

 

my buddy has the same motor i think in his rsx, but none the less he just put in a injen intake things nasty. HKS makes a nice exhuast for it to.

 

i guess i forgot to mention lol sorry, it already has an injen intake with Tein coilovers, and a custom 2-1/2 inch exhaust all the way back...any other suggestions?

 

turbo? and tune for reliability?

 

i was leaning more towards turbo anyway, whats necessary to do a turbo "right"? like what parts, etc.......

 

quality mani, turbo, intercooler, injectors, pump, and all piping, also and most of all a really good tune!

 

thanks man, keep the suggestions coming!

 

Are you planning on peicing together a kit or buying a prepackage kit. If you are planning on sticking with the a3 than urbo is the way to go for any real power. unfortunetly an all motor a3 at this time is laughable. if you have any real technical questions regarding your boosting of the a2 look towards k20a.org or even ephatch.com

 

Ditch the stock head. A rsx or a rsx types head are the way to go. The si and rsx head are different and your head makes less horse power.

 

yes chirs is "right" the a2 head is better designed especially the cam profiles however most people that have done this head swap seem unsatisfied with the power gain also the a3 in its natural state is perfect for boost low comp and all. If you are serious about staying all motor a swap is the way to go at this point reputable companies are just now begining to produce parts for the a3 as way of internals
