Hey just pulled this from the hybrid swap forum, wondering if anyones heard of this. Iv tried googling with no luck
Sorry I'm on my blackberry and can't copy the link at the same time but here's what the poster said.
"ive recently heard of folks using the passenger head from a non fsi 4.2 v8 on a 4cyl bottom end for the larger ports and cams along with the infinite ablity for adjustment of the t-belt sprocket on the cam. i currently have one at my fingertips thats still bolted on a v8. ive counted the teeth on the cam gear and its double my crank pulley. also the intake and exhaust bolt patterns and angles look to perfectly match a regular 20v head. also the valve cover is shorter and flatter that any regualar 20v. just wondering if anyone on here has physically done this and any small things i need to know before i do this...also curious as to what compression ratio is on a 2.0 bottom end...
