flaco if that is truely a PT88 which is the same as i have then its a journal bearing turbo and not a ball bearing. You should edit that post of yours over on pt.net
but thats good times for that combo!!!
maybe, it was ordered from Trick performance.....i'll look up my recipts but i think he said it was a BB....
anyhow this thing spools up quick though....3500 rpms = full boost
