This is going to be a winter project i have a 2.0 in my car right now. What I am aiming for is 450 hp so any information on the 2 different sizes of motors would be very helpful so I can start to order my parts.

 

2.2 will give you more power/psi with similar setups

2.0 sounds better with the extra 1000rpm's

 

Go with a 2.1 AP1 That's what I'm about to do. F20c bored to 89mm
