i wanted h22 and was planning on it, but after some research and thoughts going back and forth between GSR and LUDE I'm gonna go with the B18c,here's what it said.
H22A (Prelude VTEC) in any Civic/CRX/Integra
The H22A engine leans in the wrong direction
Civic engines have blocks that lean forward while the H22A block leans backwards, towards the firewall. Even though custom fabrication will mount engine, it's still not suitable for this chassis.
Fabrication issues
Custom fabrication is required to get the H22 engine to fit. The stock motor mounts have to be removed and new mounts relocated, making this an expensive job. Modern day cars are designed from the ground up as an integrated structure, and this includes the engine. Moving mounts around causes the structural characteristics to change. Furthermore, it also increases the chance of a screwup happening.
Chronic understeer
The heavy load up front will cause tons of understeer. Furthermore, the added power up front will cause the front end to lose traction too easily. What you have is a car that goes fast, only in a straight line.
