I am building my 98 LS integra turbo for about 350-400 HP hopefully out of a GT30R and I am specing out some pistons. Originally I was planning on a GE sleeve and a 84mm bore. However, I just found these pistons cheaper online and was wondering if going with the smaller bore size is that worse of a difference? I can save about $150 if I but these and only go with the 81.06. This shouldn't be a problem to bore sleeved cylinders to that 81.06mm size, should it? I figure at least I will have some room to re-bore the sleeves if any problems occured. Any opinions would be appreciated!

From researching this topic some more, I found that an 84mm bore would turn my engine into a 2.0 liter roughly. Is it worth it to bore the engine out this little amount, and have less material for future boring(if any problem arised)? With an 84mm bore I believe I would only have maybe 1 bore left on the sleeves.

 

If you want to go to 84mm which would be worthwile you need to go to a aftermarket sleeve.For pistons either you listed will work great it is more of a personal choice.I would go with a 81.5mm or 81.25 that way you make sure you are starting with a nice round hole as they cylinders will have to be rebored.if you check with the sponsors on here you will find some running a piston rod combo for a good price
