PLEASE HELP putting 325i head on eta engine
Timing belt broke and bent all the valves. I want to improve performance and have been thinking about putting a 2.5i head off a 325i (s). I hear this will lower compression down to about 7:1. If this is all true do you have any suggestions to help performance with me putting on a new head. I was going to use the i intake also. Will this help alone. If you can help please do. I don't really want to put it back together stock with a chip only.
