that turbo is 1 you should stay away from, if you can shift out at around 9k or higher then go for it but on our cars it would be a problem. If you desire something other than mopar S3 and you want to tune then go get a 50 trim. You can find some sweet deals on that turbo + the supporting mods...goodluck

Yes the 42r flows quite a bit of air, but I think if your revlimit was set to 8200 or so it would be a great turbo. Seeing as most 50trim setups on the stock limiter have 2k rpm powerbands the 42r would provide you about the same, seeing as it'll spool around 6k most likely, depending which housing you go with. That turbo doesn't have a problem making 800whp on +35psi.
