depending on how much you want to spend I would call Haisley Machine and talk to them about getting a s4 turbo. there are 4 different exhaust housings that are readily available for it. Just put the smallest one on and i think you might be able to push it. it is the same turbo that competitive pullers use just with the bigger housings. If it can withstand their hp and abuse it should last an average person forever. however i dont know how much more fuel you might need to make it worth while.

From what I understand the SP66 and SPS66 are basically the same thing. The difference is that the Industrial Injection SPS66 has a larger shaft which stands up to any surging, barking, etc much better. Oh, by the way, there's an SPS66 in the classifieds with truck attached.

I don't think they are exactly alike.
From what I can tell the SP66 from HTT has around a 60mm turbine wheel where as the Super Phat Shaft from II has a 70mm turbine wheel.

The "Phat Shaft 66" from II would be equivalent to the HTT Sledpuller 66.

(I could be wrong, but I don't think I am).

Shaft sizes should be all about the same since you are using the same base S300 turbo.
