eddie kihm (owner of peak performance) sells both a 2.2L and a 2.3L stroker kit for the sr. they are running the 2.3L in their car for FD.

also eddie was origianlly going to do a 2.2L and a 2.4L kit but the 2.4L was way to aggressive and extremly unreliable. it would pop a head gasket after about 50 miles. but the 2.3L is a great kit.

here is a link to thier site.
