archemitis Posted December 17, 2004 Share Posted December 17, 2004 nice, most subarus(non boosted) i have pulled apart look like a ball hone and a rering is all they need. you can usualy still see the cross hatch from the initial machining even on a 200kmile motor. so standard rings should work for most peepl.

erik litchy Posted December 17, 2004 Share Posted December 17, 2004 your metric to standard conversion doesnt sound right Quote Link to comment Share on other sites More sharing options...
WJM Posted December 17, 2004 Author Share Posted December 17, 2004 your metric to standard conversion doesnt sound right the overbore is directly whats listed in the EPC. Quote Link to comment Share on other sites More sharing options...

MPFI and Carb pistons list as SAME part number. SPFI are separate PN, as are the 85-86 Turbo( pistons, 87-88 B, and 88-90 B. umm get a set made should be much better in the long run Cosworth builds all their engines with OE SUBARU piston rings. Go figure. Quote Link to comment Share on other sites More sharing options...
