So i found my 4runner has 0.50 pistons now i need rings.The pistons Are OE over bore but i was looking for aftermarket rings like total seal or maybe a chrome ring(told that would be best) the motor i thought was a stock 22rte but i guess not lol Any help would be great for stock oe parts or aftermarket. i will be on aim for a while so if you can help let me know.

the motor is from an 86 4runner sr5 turbo

 

go to LC engineering if you want the total seal rings, i think a good set of moly rings would be fine though.

stay away from the chrome ones, usually your engine will wear out before they seat.

 

thanks my friend sent me the link to them and i have been looking all night. I found .40 and .60 but no .50 im going to call in the morning and see if they can get em

 

The .50 on your OE piston is metric (mm) & .030 .040 .060 is standard (thousandths)

 

Our 85 22Re has 75 on the pistons. Machinist said that is about .030 oversize.

 

there are exactly 25.4mm in 1 inch

so .75mm = .029527" ~.030
and .50mm = .019685

(to be picky about it)
its 30 thousands or .030 inches. but not .30 thousands or .30 inches

Yup , I added a few zeros to my post

 

to be picky about it... it is 30 THOUSANDTHS not 30 thousands

thousands is to the left of the deciaml point, thousandths is to the right...

 

Dang it! OK post edited again . BTW nice sp

 

thanks guys got them in and the motors in
