CHeck with Phil on the T-51r and I think the guy who dynoed before you at engineered at the last meet had a t04r...actually, if you go to to4r , the should have the info you're looking for on that turbo, at least

Dan,
Not able to answer your question directly since I don't know the compressor dimensions in mm. I can tell you that the T04R is *very* comparable in terms of power output to the turbo that you are currently running. Definitely wouldn't be worth a swap.
However, the T51 is significantly larger than either the T66 or the T04R. Ultimately, this turbo is capable of considerably higher flow then either of the others mentioned.
I assume that you are asking 'cause you are thinking of upgrading?
Don't know the specifics on the different variations of the T51R, either (SPL vs. KAI). Sorry.
BTW, Phil's running the Fastrax T51 on his car. This is a customized version of the T51 built by John K at Fastrax.
I am sure that Phil can give you the specifics on his configuration.
Good luck with it.

Though there are hundreds of different wheel combinations available for any turbo, HKS has found these to be the favorable choices in regards to standard upgrading for the Supra. Here are the Turbine wheel dimensions,
T04R --74.2mm./64.7mm. T-51's -- 82.0mm./ 71.4mm.
T04R compressor A/R is .70 The T-51's aren't available, maybe because of their unique anti-backflow chamber built into the housing or for proprietory reasons.
The LISTED T04R turbine A/R are .81,.96, 1.00. I've used the dualport .84 and found that to be a very good choice. Again there are many to choose from. The T-51's are 1.00 and they don't list any other combinations yet.

What are the advantage or disadvantage in a T04R turbine for a .84A/R dualport vs the single port .81A/R?choritsu-shi said:Though there are hundreds of different wheel combinations available for any turbo, HKS has found these to be the favorable choices in regards to standard upgrading for the Supra.

Yes, I also agree....but there is a very important feature with the HKS header design(6 to 2) that hasn't been mentioned. Known as a "dual-port" or "split-port" design. This feature builds more velocity and creates a more reponsive and stable boost, especialy when used with a "dual port" turbine housing. This allows you to run a larger A/R turbine with great response without sacraficing your top-end. Not to dis-credit GReddy's quality, but on a "single port" design header(6 to 1), to reduce lag, normally you would go with a smaller A/R turbine housing. But this obviously reduces your top end and can also prove fatal. Smaller turbines are more restrictive and can create too much back-pressure and tremendous heat. This causes either pre-mature/permanent turbocharger damage or the excessive exhaust pressure/temperatures before the turbocharger(normally not monitored by most) can and will damage your motor. That smaller turbine housing may work great for that one 10 second run, but we're only talking about 10 seconds at one time....that isn't enough time to take a
