Hey, Ive searched and found conflicting info. im at work so I cant measure my GT35R (its in the garage) but I need to buy this 90* 2.5 to 2.75 " silicone reducer elbow (my iC piping is 2.75") and I need to know if it is likely a 2.5" compressor outlet. Its the GT3582R. I have seen on som sites they can come with a 2" outlet but this was on a Porsche performance site and may have been a custom thing for fitment issues. I jsut need a quick answer and then this thread can be done with. Thanks!

Do you have the 4" intake? If you do, its likely a 2.5" outlet. But do not quote me.

if its a real GT35R ( T04S .70AR w/BB ) it has a 2.5" outlet - no GT35R has a 2" outlet

Yes, its a real BB GT35R. but I did see a 2" outlet on a Porsche performance web site, but I think its custom for fitment issues.

The traditional/standard GT35R comes with the T04S compressor housing, which uses a 4" inlet and 2.5" outlet. You can also get the GT35R custom made with the T04E compressor housing, which uses a 3" inlet and 2" outlet.

with the T04E housing, then its a ball bearing SC61(precision term) or ball bearing T61(garrett)
