that fits ALL EA82 engines, turbo or not. and thats the STD bore.

 

there are 9 sets left in the country....I cant get them for USMB for ~$180. Complete set.

 

010 is the .25 over, and none in country, ~180 on those as well....can get from JAPAN.

020 is .5 over, 11 in atlanta... ~$121 usmb cost.

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.

your metric to standard conversion doesnt sound right

 

:confused:

 

 

the overbore is directly whats listed in the EPC.

what about carby pistons to match those rings Will? Me gonna need a nice set when I rebuild a motor for the RX....MWAHAHAHAHAHAHAHA:grin: I'd need the pistons to match the last bore of rings you have posted on here...:D

umm get a set made should be much better in the long run

MPFI and Carb pistons list as SAME part number. SPFI are separate PN, as are the 85-86 Turbo(B) pistons, 87-88 B, and 88-90 B.

Cosworth builds all their engines with OE SUBARU piston rings. Go figure.

:confused:

 

 

the overbore is directly whats listed in the EPC.

10 millimeter = 0.3937008 inch

 

thats a big overbore to me.

I was talking about pistons

so then what pistons should I use in my RX for the higher compression which I believe was like 9.5:1 or so....?
