In another thread, the question of increasing the compression of a 2.4S engine was discussed. Using 2.2S pistons seem to be the (relative) easy solution. What are the possibilities with an 2.7RS engine? Custom pistons? (as I'm not aware of standard Porsche pistons suitable for this). Who has experience? Any dyno results?
I've heard of custom pistons, doing about 10.5:1, offering 240/250hp. Not bad.. Thanks for the response!
