as long as it fits :)

So we are all going to have something different :)

They are slightly different, one has a T4 flange.
Remember these are all hand made even the collectors so there will be some variances.

Well I havent bought anything yet....but my bank likes the 60-1 cause its half the price :o

You can get a GT35 compressor without buying a GT35r

The 62-1 is fine.

Its just the GT35 compressor is a much better option if you had a choice.

And how is it ok for m20 2.5 liter motor 7000 rpm rev limit vs. not ok for 2.5 liter m50 (7200 rev limit)?i am confused again...

The 60-1 is not that great for an M50/S50 engine, unless you want to run no more than around 8psi.

Then why does TT use that as their stage one turbo, I have seen plenty of dyno sheets on bimmerforums and that was suggested to me along with the gt35r

[01djb]

Well that sucks...I guess my turbonetcs 62-1 is not going to work well above 8 psi neither because it is not a gt35...Oh well... Live and learn i guess.

Because I had one on my M20.

Looking at the Compressor map, it does not fit the 24v motors too well. Its PERFECT for the M20 up till around 420hp.

The GT35 compressor has a much wider map, and fits the M50 much better. An alternative is the 62-1 but still, the GT is better.

Why may i ask you can only run 8 pounds of boost from a 60-1 on a m50/s50?(sorry i am still learning)
