Sorry I cant answer your question about fitment, but I will vouch for the quality. Mine came in yesterday, and it's a beautiful piece.

 

2.5" is the most common. I don't think it creates any more lag than a 2" system. Some people might tell you it does, but I don't buy it.....

%gen Civics have shitloads of room for intercoolers. You will have to trim the bumper a bit for any intercooler(usually).

A general rule of thumb is you can't have an intercooler that is too big. Don't be a smartass and say "What if I'm running 4psi and I have a 36"x14"x8" intercooler". :P

Both fmics are good but I'd personally go with the CCA. My 6in fit perfectly except for trimming the bumper a bit and any bigger you would have to start hacking. I personally try to stay away from the sawzall as much as possible. :P

 

I love my Sawzall. I have two, one is cordless. I made "custom" motor mounts with it a few minutes ago.

haha, yo ill hack up my bumper without even looking if i need to cut ---- off!!!

in fact, its not even my bumper, its the bumper that the spanish kid that stole my car, as well as my b16 and thousands of $$$'s of other accesories, put on my car so he could roll it back onto the street ( not being racial, but i talked to the kid that stole my car on the phone,.,.... now thats a whole other intresting storry)

so yeah, i guess ill go ahead and order up a jrc 8" relatively soon....

so for intercooling piping then, the lot of you would recoment me going all 2.5??

how do i get the small hole from the outlet ob my 14b into the 2.5" piping that cant posibly be a smooth transition!?!?!?!?!

 

Both intercoolers are good. I've never had a JRC, but I have had a CCA. When things are too close to call you go with the guy that's actually posted on HMT in the last 2 years.

Always go with who you know.

 

well, i just bought the jrc intercooler!!! thanks for all the help u guys!!

 

You can use a transitional coupler but those things are expensive. My silicon transitonal coupler cost something like 25 bux but home depot has something simliar and cheaper.

 

that big JRC sure looks nice but sheesh...got pressure drop?

 

I love mine
