anyone have any experience or use one of these? it has the SS mitsu bolt on housing, triplex ceramic bearing system and the billet tip.

what do you guys think? should be night and day from the e16g. can't wait for it to come in!

Edit: It arrived 11-27-13

It is everything the seller said it was. its very clean and look hardly used. he sent me everything in the pic with the sale restictor line, oil return line, turbo outlet coupling, gaskets and bolts. i am extremely satisfied, less than 2 days to my door.

What do you think?

Is that one of their turbos that doesn't use an oil feed/return?

I haven't used one, but have read up and it should be very comparable to my Precision 5857 ball bearing Billet. Look for full 30ish PSI in the low-mid 4k RPM's, and depending on supporting mods, around 500whp around 28-31psi.

Edit: You might see some faster spool with the bolt-on housing. I love it on the street though. Tons of power from mid 4k till 8500.

I love my Turbosmart Comp 40. More responsive than the TiAL MVS I had on it before. JNZ can get you a good deal on either though.

I'd like to see if this thing holds up. I've read countless woeful tales about Comp turbos. I'd like to actually see a success story with one for a change.

I take it this is a used turbo? How many miles did the seller say were on it?
