So im boosting my car. i have the intercooler already, and im gonna order the piping soon.

the intercooler has 2.75" inlet/outlet.

my question is, with the spoolinperformance intercooler piping kit, what couplers will i need?

heres a link to the Piping kit. its 2.5" and 2". http://www.spoolinperformance.com/94...ing-p-587.html

If im correct, i assume ill need 2 2.5" straight collectors, 1 2.75"-2.5" reducer, 2 2" straight, and a 2.75"-2" reducer.

 

Not sure what turbo or throttle body you're running, but I'd say you'll need two (2) 2.50"-2.75" reducers (IC-to-2.5" piping and TB-to-2.5" piping), one (1) 2.50" straight (2.5" piping connection), two (2) 2.00" straight (2.0" piping connection and turbo-to-2.0" piping), and one (1) 2.00"-2.75" reducer (IC-to-2.0" piping). I presume you wanted to put a 2.5" straight to the TB. You can. But a 2.75" fits them better.

For t-bolt clamps, you'll probably need to add another .35" -.50" on the piping O.D. measurement to attain the correct range of the clamp. Can't remember the exact number though, but it'll depend on type of coupler, too (3-ply, 4-ply, etc.). Just food for thought.

 

thanks man. totally forgot about the TB maybe not being 2.5". going on a t3/t04e 57 trim. pretty sure its a 2" outlet.
