Hi all
Just acquired an x90 for classic trailing. The car is a bit underpowered in heavy mud.
Anyway I have a spare engine that I can rebuild myself. Just looking to extract whatever extra power out if it I can.
What is the maximum overbore I can safely do. Any recommendations on pistons. Everything will be balanced before it's put back together.
Also (just for now), are there any good suppliers of parts for these cars.
Many thanks in anticipation.
