Getting ready to send in my bottom end to get "bored" out, was wondering what would be the stock cylinder size where the piston sits? Also when i say i want a .20 over bore, what would be that size after it is bored out? Sorry if this sounds kind of stupid, i just wanna be sure and done correctly the first time! OR even if anyone has a site i can go to for this type of information. thanks for you help!!

 

OH the motor is a 98 DOHC if it matters!

87.5mm is a stock piston size, .020 over is 88mm

 

thanks guys for you help, the website was really informational, and is that 88mm what my aftermarket pistons should be? if so the ones from MPx should jus drop right in, right?

 

88mm would be an aftermaret .020 over piston no matter the brand...but if you are planning on using forged pistons, make sure the shop measures the clearance specs properly...otherwise it will all be a waste of money

 

so a good rule of thumb would be to get the oversized pistons first n give it to them to measure before they start to bore it out. right?

 

deffinately....mainly for the fact that forged pistons need more clearance then say a stock piston or a HP piston would...this is due to the fact that forged pistons will expand more under heat then the others will

 

thanks for all the help again guys!
