That is not a 100mm inlet or a 60mm outlet on the compressor. Could be a 57trim wheel, and is an AR.60 compressor housing. Without seeing the exhaust side there is no way to tell what it is, but you should hope that it is not the O trim AR.70 exhaust side that you gave specs for. HKS offers the same compressor section with an AR.84 P trim exhaust side with there RX7 turbo kits so don't get worried yet. Show a pic of the exhaust side and we can tell you more. By the way, that compressor side on your turbo is capable of 400rwhp on a ported FD.

Thanks alot guys for the input... I will send a picture of the Exhuast side tonite...

Guys tell me if i got a good deal.



I bought this turbo + turbosmart Pro-gate 45mm Wastegate + Manifold + Downpipe



I got this deal for $1000



Did i get a good deal?



The turbo was barely used...

Sounds like a good deal.

Ok just griinded off the flange becuz the outlet which was welded on by the last owner was smaller than i wanted it to be... The flanges outlet was only 2 inches... Now i am welding a 3 inch Pipe....



Also i am attaching some pics of the exhuast side of the turbo... I hope this helps identify... I Measured with a vernier and the exhuast side is approx. 59mm... The pics are from a P-900 hence the bad quality



Is it tooo small??



Thanks

here is a view with the old flange....



I don't get it... why would someone make the outlet smaller would'nt that generate more heat and cause restriction...

Some FeedBack Please!!!

You know they make like...rubber adapters that go from 2'' to 3'' right? @_@



I don't like the idea of grinding and welding, honestly. My turbo's a T3/T4 hybrid, .70AR. I just have a rubber adapter that connects from the compressor housing turbine which is only like 2 inches or whatever to a 3 inch intake piping w/ filter...

i think the exhaust side a/r is .70



will that be too small for a fd??



how much hp should i expect from this turbo at 15psi on my street ported motor??

In my opinion the O trim AR.70 exhaust side is going to offer quick response, but will choke the motor up top. I say max of 325rwhp at 15psi and the motor will not want to rev past 6500rpm's. You would be better off with one size up on the housing and one size up on the wheel (AR.84 P trim).
