boosted b20?

[vancem3m3]

how much can boost can stock b20 sleeves handle? and how long can you run it be cracks a cylinder?

Well depends on your set up ,But I would not run no more then 3-7 psi depending on your set up, with it being tuned then 7 daily thats as fas as I would go due to I wouldnt want to keep fixing or buying motors

most stock honda sleeves can handle up to 450-500, but the b20 are more prone to crack at lower power levels. i would say about 300 on the b20 to be safe at the most.

boost is a relative term because one turbo at 5psi is less than 5psi from another turbo. i've tuned b20 vtec turbo's to 280ish w/o sleeves cracking.
