Whats the highest realistic bore you could get from a 20XE??
I have a nice new set of 90.00mm WRC spec Cosworth pistons and I'm dtermined to make them fit into the new engine!!
If the original is 86.00mm, then that means +4.00mm, so thats 2.00mm bore in all directions!!
Anyone experimented with an overbore of this nature????
