Now...when i rebuild my engine, I am gonna open it up 2mm and go to a 85mm bore on my b21. I am gonna get pistons to match it all. Now I have a couple of questions:
1. Will it hurt if I drive stock like this for 6 months? Like will there be enough fuel in the cylinder during operation after the enlargment?
2. I plan on going turbo, so how much will it affect performance if I go to a 2.5 exaust instead of the preffered 2.25 n/a? I want to know this for when i do my before rebuild baselines, and after....
Thanks for any info...
