IM wondering, what is a good size turbo to go with the SR20DET to bring it up to around 300-350+ and still make it fairly steerable, im not looking for somethingf ro the stirp, Im more of a autoX/ Drift style racing. But I would like the power to suprise Corvettes and shit. Anyway Ball bearing would be good, because I need something more reiable, oh and what is the stock trubo good up to, if I want it to last... yeah I could turn it up to 18 but the turbo would be gone in a few months, thank for the help agian.
