Default need help measuring my twin turbos.

Hey, So i got the twin turbos finally from auctane 71 or jonathan hendrix after a long dispute. here is my qeustion though, they are the t04b housings and when i measure I get

Inducer 2.167

exducer 2.951

Not sure of the make of these they are supposed to be t60s but using the formula

(inducer/ exducer)2 *100 I get 53.9

To these are t54's? am i correct in doing this. I measured from tip to tip on the most forward "fin" the indcuer same for the exducer

Yes, that specs out to be a 54mm turbo. Those are definitely not T60's. Also measure out the exhaust side, we can find out what wheel it is. More then likely its a stage 5 or T350. Which okay for a mild buildup, but for big power, thats a no no.

The exhaust side is a T31. That is a tiny wheel and actually smaller then a T350. Those turbos will cause excessive backpressure if you plan on making any real hp.

closest i get is for a TO4b 54 trim in =2.170 ex = 2.950 flow rate = 45 #'s /min
