Coolant and oil Lines, RRFPR and some piggy backs to control fuel and timing. The TD04 has a Wastegate pressure of 8 PSI so your definitely going to need fuel and timing mods.

Ohh also your going to need a WRX crossmember

It never hurts to use the on this site and READ, READ, READ! The more you are informed, the better you will understand what you are getting into.

Also you will need a waterpump from a WRX. And from what I read and tried, the stock intake will work with the WRX intercooler, but it is TIGHT!

the water pump housing will be touching the wrx cross pipe idk if you want it to because that would raise the watertemp by alot. the pipe will fit but it will be making contact, any turbo waterpump will clear it by a few inches so it would probably be better.

There is only one outlet on a factory 2.5 engine. I used a 1/4" pipe tap to plug the other two smaller outlets. That was after I "pulled" the steel nipple from the pump.

Go to RS25.com

You don't need the crossmember or waterpump ONLY if you buy the up/down pipe fit for the RS. They bolt up to your stock header. I am working on a kit right now and all i need is the WRX turbo and oil/coolant lines. I really recommend you go to that site and look over everything that it has to offer. I can guarantee you will find almost anything you are looking for. Let me know if this helps.

Sure can, but the water pump is installed so it won't be the best pic.

I read that you cant use the wrx uppipe on sohc engine even with the wrx crossmember because the uppipe will run into the head, anyone else hear that?
