Because im going to maily drag, and H22 there excells at itmls said:I always thought that the H22A mounts with the head titled towards the firewall. Im quite sure you need to retain the tilt so everything lines up correctly. Ive also heard that this is why pig power has clearance problems due to the need to have the head tilted towards the firewall.
For example, some guy put an SR20DET into an old school Bluebird & the front of the engine needed to be tilted down towards the ground at something like 3 degrees.
Why not go for a B18 engine instead of heavy pig power for a more simplistic swap?
