Hello, good afternoon everyone. I have a set of pistons for evo9 buschur spec but the information sheet on the gap for the pistons was lost. Could someone give me some guides for the gaps for top ring , second ring Im aiming a boost around 45 psi I really appreciate if someone can help me

Though one of the Mitsi' chaps would have commented.

The piston manufacturer should have the recommendations on their site, or the ring manufacturers will certainly have it.

Had a quick look online.

Different manufacturers recommend different gaps, according to their product. And many guys are running what they felt was best. With what seems mixed results.

Best bet will be to contact Buschur racing directly. Sorry.

If they're Buschur spec pistons you might as well ask Dave since he's back working there.

We usually reply within 12hrs (often sooner)
