ITR and CTR exhaust cams are exactly the same, 2001 USDM ITR intake cam is also the same specs as the CTR intake cam.

They can be obtained all over the place for reasonably cheap.. The only thing thats held me back from doing that so far, is the added costs ontop of buying the cams.
You'll need to get new valve springs (from the ITR or CTR), and retainers.. Then if you want to make full use of the cams you're gonna need to get your ECU chipped so you can rev higher and make use of the bigger cams.

If you're actually going to turbo it, I wouldn't even waste money on the cams.. Spend your money on parts that will help the turbo produce more power instead of wasting a bunch of cash for 8-9 hp.. Look into a bigger exhaust, bigger intercooler, etc..
