If you have a 2T-G and want to go turbo, you can use:
2T-GEU inlet manifold
3T-GTE injectors
3T-GTE exhaust manifold
CT20 (3T-GTE) turbo
It all bolts up, you just need to make a pipe from the turbo to the throttle. Also oil suply and drian to the turbo.
You can use a 2T-GE distributor by itself, but for computer controled ignition I think you need a extra sensor in your distributor, like what a 4A-GE has. What the best ignition setup for a 2T-GTE with aftermarket computer?
