motors come pretty complete. Just make sure you ask that it comes with a turbo. They will say, ok, but they don't warranty them.

Ebay for IC's

I used 3" exhaust mandrels and straits. I might try 2 1/2 to see if I decrease or increase performance. 3" is a bit on the large size, and probably overkill, but who knows until I try to decrease the size.

I use EVCO house of hose to get the 3" silicon hose and clamps. These are $3 a clamp, but these are awsome clamps, and are needed if you don't want leaks.

My whole IC system cost me $500

parts:
6 mandrel bends
6' 3" pipe
12 inches of silcon hose
8 hose clamps
intercooler
mod for smaller inlet/outlet on ic
