k so i kno one day im going to boost. no doubt about it, instead of the n/a ls vtec thats in the del sol right now its more then likely gonna b a boosted b20 vtec. i had a couple questions/concerns tho.

i was thinking of doin an all honda part internally (bottom and top) setup on boost. of course this means upgraded rod bolts n shot peend/polished b20 rods n what not (i have this already on the n/a setup so ill just get another set done for boost.) my main concern is the b20 pistons. how strong are the ringlands? do they hold up to heat well? i kno they wont b as strong as a forged piston, but honda knew what they were doing when they built the b series. is there some sort of heat dissapating coating that can b used on pistons? i kno there are coatings for exhausts, intercoolers, n such, but would they work on pistons? (i believe its called pro coat. its a black heat disapating coating).

also, i know that with a gsr head on the stock b20b pistons its about 9.0:1 compression. which is decent for boost. my only question is with this compression and the oem parts, how much boost could b run (93 octane pump gas of course),and how much power can be expected? im not shooting for anything massive. id b happy with 350 to the wheels on a reasonable amount of boost. its still gonna b a dd with ac.

i have basically everything needed for the b20 vtec, minus the block. the turbo kit is where the big money would b spent. anyone have any recommendatoins as far as a turbo (size, type, etc) and a good log style manifold that will allow ac to b kept?

any and all imput is appreciated. this isnt going to happen over night. im still doin mods to the current motor. but i plan on just swappin the head over (again all honda parts) and upgrading to a better intake manifold n tb. like i said its not gonna b an over night project, BUT it WILL happen sooner or later. just wanted to c what ppl had to say n if anyone had done it b4. thanks in advance!!!

 

wouldnt use b20 bottom end, sleeves are weak and for 350 u dont need to do anything to bottom end, just 2mil HG if u want.

 

+2 b20 sleeves are not the greatest....

Stock cast piston ringlands can't handle detonation at all, tuning is key when it comes to making them last.

 

thanks all. are ls sleevs better? im assuming theyre a little thicker. would a block guard do anything to help b20 sleeves at all?? or would i b better to just beef up another set of ls rods and slap some stock ls pistons bak in this block?
