i was looking into boosting a b20 for my friends car and i saw on hmotors the 96-98 spec motors come with 8.8 compression i wana know how much psi i can boost cause i saw some one on youtube do 15psi tunned on a bone stock b20. any info would be appreciated

sohc sol

the sleeves arnt as strong as ls motor so 15 should b the max on the stock block 10 psi would b alot more safe

Key here is to keep denation down.

you can run 5psi or 50 psi all depends on the size of the t3/t4 you want and all about the tune. The video above is my coupe when I had a b20 turbo then b20vtec turbo in it.

psi is irrelevant, hp is what breaks motors

i somewhat agree but I think bad tunes break motors
