On an 84mm gsr or ls block with ls crank....with high compression pistons and gsr head...how would the valve to piston clearance be affected....isnt bad already with a b20 block....you with some 11+ c/r.... I need to get my mind straight to start getting **** together...thanks

 

We have a B20/VTEC with 12.5c/r pistons on a 85mm sleeved with flat valves and never had a problem.

 

on what block... and with an ls crank right...

so what block/crank/rods combo u using and ill tell u the clarence

 

well now that i think about it....with an 84mm gsr block or ls block....what crank/rod combonation do u need...i mean if you keep it ls crank and rods ithink there would be clearance issue....correct me if im wrong

 

the ls and b20 both have the same cranks and rods just the b20 is bored to 84mm u can use the ls crank with the b20 but not the gsr if u do 84mm gsr u need gsr rods and crank the gsr-ls is a 81mm block u would have to get sleeved and bored

 

Well yea...thats what I was originally asking...with a 84mm bore gsr or ls block....if i use high c/r pistons with a gsr head and ls crank and rods do a would there be any clearance....because yea 84mm is the right bore to achieve a 2.0...but i would also need a different stroke...which ls and b20 have.....like when ppl go ls/vtec and stuff like that....but just wanna know about clearane

 

bump

 

u are saying gsr or ls block with ls crank are u building a gsr or a lsvtec the ls block u use ls crank and rods gsr u use gsr rods and pistons....

 

doesnt really matter...its the same block...one has oil squirters the other one doesnts....thats why im sayin "or"
