just want some input on how long ur block lasted and what u revved it to woundering if i should get another b20 block

 

how long did yours last?

what were you revving it to, and what was done to the motor?

 

umm i got ripped on my motor it was cracked already well it still ran but it has to hairline cracks in cyl 3 it also has block guard it has 12:1 je pistons im pretty sure the guy i got it from revved it to 9k but i know u should only take it to 8500 well i only drove for a week before i took it out i didnt go past 8400 oh the tha motor suposedl has only 8k miles

 

i did 84.5mm endyn 12:1 pistons in a b20z, and built it & beat the **** out of it for like 8,000 miles... then it started to run like ****, and occasionally puff white smoke. pulled the head, and it cracked between 2 and 3. it made like 210 and 140 at the wheels with ITR cams, and i dyno'd it when it was "running like ****", so i think the sleeve was cracked when i was onthe dyno. oh well.

 

thanks for the info...

man, starting to get paranoid about mine now. heh

 

i ran a full season 1200+ miles, but im getting a sleeved ls to replace it..

 

yea i think ishould go with sleeved ls

 

are u gonna run the stock bore and stroke on the LS?

 

still going strong.....7k on it, 84mm ibspec wisecos, probe rods, and rzported head on blox stage 2 cams.....225whp,160flbs rev to 9k.

stock strock 85mm bore

 

need some advice should i purchase a 85mm ge sleeved ls bare block localy $750 and buy new pistons

or resleeve my b20 $900 and use my internals and keep stock 84mm bore

 

are the internals ok on the b20 right now? if so it might just be worth it to sleeve it and you will be ok!

 

yea all internals are good 12:1 je pistons eagle rods just need new rings yea figured it would be cheaper to resleeve b20 ill post dyno within 2 months aiming for 220
