IM PLANNIN ON GOIN ALL-MOTOR LS VTEC
IM GETTIN A STROKER KIT N I WANNA BORE IT OUT
CONSIDERING I CAN GO BIGGER NOT SURE WAT
SIZE I CAN DO?

I WAS THINKIN MAYBE I CAN GO 84MMBORE X 95MM STROKE
WHICH WILL SET ME TO A 2.1L MY QUESTION IS
WAT COMPRESSION RATIO WOULD CLEAR OR BE SAFE FOR IT
AS FAR AS ME PUTTIN SKUNK2 PRO2 CAMS IN A GSR HEAD???

IF ANYONE HAS AN OPINION PLEASE LET ME KNO

 

if you wanna go 84mm on a ls you'll have to get the block sleeved but i think it may be possible if i were you i would just get a b20 if do not wanna sleeve im buildin quite a few b20s and if had no problems and these are allmotor.
i would suggeswt get the head p&p valve train but it should be good up to 12.5to 1 is what i have done

 

I HEAR YA MAN SO I WOULD STILL NEED TO SLEEVE DAMN...
WAT OVERSIZED BORE CAN I GO WIT WITOUT HAVIN TO SLEEVE

THE THING IS I ONLY HAVE B18B BLOCKS

 

the most u can bore out on a stock b series block without re-sleeving is 82mm, the most i would suggest goin is 81.50mm, jus to be on the safe side though, its all up to you though
