i made up my mind. i'm going to get pr3's...now my question is, should i just get the standard size??? (or..do they even have pr3's in oversize??)

i thought i read something about going oversize to ensure proper fitment or compression..or something like that. it's 2am..i can't remember too well. help me out here guys, thanks.

 

It really depends upon the condition of the block. Sometimes you can get away with honing and reringing it and be done with it, other times it's necessary to go with the oversize pistons. I've never personally "had" to have a block overbored, but sometimes is just a good idea. The condition of the block will tell you.

 

wow..thanks for the input. now someone else let me know where i can get some pr3's at a good price..or..i'll just check the sponsor marketplace..

 

Im going with the same pitons.

yeah i would go overbore. so when you machine it, it will fit to piston spec. If you throw in standard, the piston wont fit perfectly as opposed to overbore due to the cylinders being worn down from the previous pistons. There might be a chance the rings may smoke.

Ive heard people go standard and they were fine. But I would rather go with the fresh bore and a rebuild so itll be a brnd new block.

Good Luck!!!
