k20z1 or k20a2 which one of these is better and more reliable. And as far as parts for these engine, which will have more aftermarket parts offerred. Can I use same part for both engines? Please help me decide!
Just keep the engine you have! It's certainly fast enough. Anything you do like that will take a perfectly good car and turn it into a basket-case. Unless you already did that by screwing with the design of the air intake and all those other dumb things people do.
