Size bore on ls set up??

I have a ls bottem end about to be sent to RS machines ....they told me to sleave it to 85 mm bore, Can i go higher than that or is this max. i use the car for everyday driving ,,,,,, Thanx for any info........




My setup for now....

A b16 head w/portflow valve train,valve job,
CnC drag ported
head milled 20 under
2 layer head gasket
skunk2 stage 2 cams
L Natural cam gears,
stock gsr header
Ls bottem end w/p30 pistons,
Itr manifold,
In a 91 Hatch dx w/azens tires 15' in
2 1\2 strait piping all the way back w/ez muffler
b16 s1 tranny
vafc controller

 

i would go 84 or 84.5 and leave some room to refinish them later incase of fucking the walls up

 

p30 pistons are 81 or 81.5

not happeneing dude.

 

look into that darton MID kit..from what i was reading about it last night it sounds pretty good. www.raceeng.com sells it for 499. Im gonna put it in this winter.

 

the p30's are in the setup i have now...this block is on its way to RS for sleaving....I just wanted to know if i could go 85 + in size.........The price is the same for any size ,,,So can i go bigger ????

 

You can go to 86 or even 86.5 if you're adventurous, but I wouldn't boost anything larger than 85 just in case.
