Measure the diameter of it at the bottom (bottom= near the backplate) of the wheel where the blades stop.

ah, thank you, much clearer!! You are used to turbo newbs ic... https://www.nopistons.com/forums/pub...DIR#>/wink.png I will go now and get those damn measurements!!

I was a turbo newb many moons ago!



Nowadays I am slightly less of a newb.

It is 3 inches. https://www.nopistons.com/forums/pub...#>/biggrin.png

Okay, now here's the question...How do you have a turbine blade with a 3" inducer and a 3" excuder? https://www.nopistons.com/forums/pub...IR#>/dunno.gif Where the blade start at the top is the inducer. Measure the diameter of the top. The exducer is the bottom of the wheel...the part that seats next to the back plate. The compressor housing is the part that is attached to the back plate. The exducer will be LARGER than the inducer. Try to get it EXACTLY measured so we can tell what type of hybrid it is! https://www.nopistons.com/forums/pub...IR#>/boink.gif

ok, now that makes sense. Ok i will go measure the inducer then, but the exducer is 3 inches.

well i got 2" 4/16s for the inducer. Hard to tell but i re measured several times

Okay, I'm determining this by the the turbonetics 2000 catalog so bear with me.



It's possible that you have a t-04E-57t or 60t. 57t measures 2.23" inducer, with the exducer measuring 2.95". The 60t measures 2.29" with the exducer measuring 2.95".



If it really is a 3" exducer, then you may have either a super V or H trim which would make it a t-04B...but dont' quote me on this(someone chime in to help me out if I'm wrong".

damn mystery turbo. Where are all the turbo gurus????? why don't they put friggin serial or identy tags/plates on these????

that would make it so much easier, do most ppl just use a ruler like i did? How could u ever get that exact????
