Hey guys, I'm going to be doing a full engine rebuild soon and while the engine is out I have been thinking of upgrading the stock k26/6.

I just want a small turbo that spools about the same, but can carry some more boost to around 6k rpm. I think something like the Lindsey Super 38 would be ideal.

Which brings me to this: I have found a 2nd hand turbo for sale, apparently it's a Lindsey Racing BB turbo rated to 380hp. It is has been in storage for 7 years. The seller doesn't know exactly which turbo it is though. Since he says it is rated to 380hp, I think it might be the lindsey super 38, but it doesn't look like the pictures on lindsey's website.

Can I ask him for any specific measurements that would lead to a positive id?

Here are the pictures he sent me:

Measure the diameters of the compressor's inducer and exducer.

Cheers, yeah I will get him to take some measurements and then see if I can get Lindsey racing to confirm which turbo it is.

That's not a turbo we ever sold. We don't drill the turbine shaft in the end to lighten since it offers minimal benefit at the sacrifice of weakening it.

That has a turbonetics hot housing. Maybe a SFR, Broadfoot, or old Huntly racing. I think LR deals with Garrett compressor and kkk hot housings. That's what I have from them anyways. How big is the discharge hole on the hot housing?

Mike Lindsey

We can tell you it has a Stage III turbine wheel with #8 housing. Our Guess is it's a Vitesse.

Thanks for the help guys. I will see what measurements he comes back with and if that can narrow it down. Comparing to other pictures I have found it does look like a Vitesse turbo. Maybe an old Stage 2 or a Stage 3. I'm not sure, but I think a Stage 3 might be too big for me though. And I'm also a bit worried about buying a 2nd hand turbo that's that old. Maybe I should save my money and do the turbo upgrade later.

Mike is this one a super 61?

Mike Lindsey

Everybody, including them used three stages of turbine then. Stage 3, 5 and P. Stage 3 is the smallest so there is no way it's to much for you. His stages had nothing to do with the garrett turbine stages so don't let that get in the way of your decision.

We would build 3 different versions of the Super 61 and that's not including BB vs 360 vs wet or dry. Then it would be about 9 versions. That's a stage 5 turbine. As for the compressor side, can't be sure with just a picture. It's not the typical compressor housing we use, which is a TO4E because they flow more then that TO4B. Look on the compressor housing where the 6 fasteners and straps are and see if you see anything machine engraved there. Super 61 usually says 60-1 but not 100% of the time. Housing suppliers pre-machine the housings for particular wheels and mark them so turbo shops know what it is without measuring.
