Have fun with the turbo kit. They are a pain in the balls on the RSX. My biggest suggestion is investing in a Hondata Kpro for you engine management.

The prices for everything don't add up. If you're buying a K20R don't put a lousy turbo kit on it. Get something like Full-Race or a custom set-up. With that being said you're not going to get away with that for under $4500. Also you're swapping from auto to manual. That is another extra expense on top of the motor and turbo.

Another suggestion if you're putting a turbo on the car put a new clutch in the new motor before you do the swap. It's much easier. You never mentioned any suspension work that you have. You're going to have to be able to keep that kind of power on the ground. This is a huge project so just do all your homework first. Good luck.
