I'm looking to swap a VF43 into my 03 WRX (currently protuned stage 2) -- sounds like I'll be installing the turbo, bigger injectors, bigger fuel pump, and possibly a bigger TMIC. I like the idea of doing the work myself... but I don't have much experience. Changing my oil is about the most I've done with a car. I have a couple friends up for helping who have a bit more know-how, but haven't done anything of this sort before.
Anyone have any advice? I half want to just jump in and go for it, and half worried I'm gonna mess it all up and have to get it towed to the shop to fix my errors.
