    I just got my hands on a k03 turbo out of a 1.8t it measures roughly 36mm on both sides. Think this turbo would be worth running or would i see no gains over the genv. I could get a rebuild kit for it for 25 bucks.

    Yea its tiny but thats why im curious, after seeing twinv6 results it makes me wonder. Honestly if i can see 300+ whp with a small intercooler attached to it ide be happy cus i can make this happen for pretty much nothing.

    That would be a colossal waste of time. That turbo supports about 250whp and you'd likely not be able to hold more than ~8-9psi to redline. You'd also be bottlenecking the hell out of the motor at anything other than idle.

    I had one on a mx6 it did ok with the 2.2l fast spool with low boost. I don't think it would be worth the time on a 3.8, the 2.2l could have had more potential with a bigger turbo, i could only imagine on a 3.8

    Honestly this sounds really fun. Get either a honda or a miata and strip it of all possible weight. Dont have the space atm but will throw this thing on the shelf for future use.
