Does anyone know of a t3 and a t4 exhaust housing inlet have the same bolt pattern?, or does the t4 flange have the bolts farther apart?

Thanks.

There are many different bolt paterns for both T03 and T04 that are the same. Any good turboservice shop should have the housing you need on shelf.

There are some many varities of each anymore with new numbers of turbo's popping up daily it's hard to keep track. The old T3 turbine housing had a smaller inlet bolt pattern than the T4 turbine housing's. I think you can go to turbonetic's site and they have a picture of flange measurements on there somewhere.
