Jerry DeMoss Posted January 17, 2006 Share Posted January 17, 2006 To up your compression ratio you can use EA71 pistons.Same bore just a little higher dome on the piston.You may have to get the pistons from a car in the junkyard. Use the search function and you will find alot of info on this. Link to comment Share on other sites More sharing options...
Ross Posted January 17, 2006 Share Posted January 17, 2006 New Pistons are also available - both the standard ea81 ones and the higher compression ea71 ones - not terribly cheap though, i was quoted NZ$450ish (US$315) for a set of ea81 pistons - not including rings.

CHIM Posted January 17, 2006 Share Posted January 17, 2006 to the people that have done the EA71 swap, Do you guys acculy notice a worth while difference? I have been thinking about doing this for a while now but would like to know what kind of performance difference they give. ~Dayten~ Link to comment Share on other sites More sharing options...
