Oh yeah, the TRD radiator and oil cap are totally going to give you made power, yo. Especially when the VTEC kicks in, werd.
That's good news. If you want to do a swap, I would recommend a third gen 3SGTE, it's a 2.0 liter turbo and makes 255hp, and can be upgraded to about 275hp at the wheels with a boost controller, exhaust, and a few other minor upgrades. Or, you can swap in any Camry V6 of your choice.
The stock engine is pretty decent if you want to get a good turbo system and have it installed.
