AiResearch t04 a/r .60 is whats on the cold side, don't see anything on the hot. Looking to add it to the supercharger to take over when the sc runs out of steam.

you would need more information then that. the info for the hot side should be stamped on the exit flange face of the housing. you can pull the compressor cover and measure the inducer and exducer size of the compressor wheel if you want to know how big it is. they use the t04e compressor cover(what you have) on turbos all the way from 58mm to 67mm is the biggest i have seen. after that they jump up to t04S covers. which are .70a/r and 4 inch in and 2.5 inch out.
inducer size is the diameter of the wheel on the inlet side and exducer size is the diameter of the wheel at its back. if you measure the size of the inducer that is generally what people refer to when they are talking about turbo size. ie 61mm,67mm etc. trim or (Exducer^2/inducer^2)*100 is also an important measurement but is generally only useful when talking about turbine size.
since generally most people run 70+mm when they twin charge. its probably a pretty good guess that it is too small for a twin setup.

Ok i'll have to measure when i get home. But in the meantime looking on ebay at 70mm turbos, is there a certain size exducer that would be better?
01-27-2015
Be careful with eBay turbos, some are ok but there is also a lot of crap.
01-27-2015
Yeah its a crap shoot, all made in china.
01-27-2015
there isnt a certain size exducer. most run 76 trim or by turbonetics standards p-trim wheels. on a grand prix either .68a/r or .85a/r

A rough eyeball with the calipers shows about a 45mm intake and a 50mm exhaust.
01-27-2015
you should post a picture of the turbo. now im curious.
01-27-2015
im not sure i follow you. http://www.turbobygarrett.com/turbobygarrett/wheel_trim
read that if you want to know how to calculate the trim. if the inlet of the compressor is 45mm thats super small.

ok got'er torn down and here's the measurements.
intake exducer 69.85mm, inducer 48mm
exhaust exducer 51.5mm inducer 72.7mm
the intake says a/r .60 and the exhaust says a/r .58

looks like a t3/t04b- would probably work pretty good on a stockish honda or dsm.
01-27-2015
So would there be any benefit to using it for now or no?
01-28-2015
no you would choke that thing out at about 4000RPM.
01-28-2015
Bullsh!t.
Its a conservative 300whp 50 trim. Its been used on 3800s in the past but dont expect to set records with it.
01-28-2015
I was thinking of using it as i have it, then replace it with a larger one thats better suited as next winters project. Just need to figure out how harge to go to optimize efficiancy.
01-28-2015
dude its a 48mm turbo...i would be shocked to see it make 300

Also just a side note, gennerally twin charging (SC and Turbo) is a cool thing but not a very efficient thing. While the S/C does "Run out of steam" per say, it really comes down to we can't spin it any faster efficiently. This is why people switch to turbos. Now, twincharging is cool don't get me wrong; however, its very inefficient. The blower becomes a restriction for the turbo, it cant spin fast enough to force the air into to motor. You would have a hella fast spool, good mid, no upper. Several guys have tried it and enjoyed it for the cool factor, but for numbers Turbo is where its at. Now its your car. Do it if you want, and take lots of pictures lol

Dude what are you talking about. No upper?? got to be ****ing kidding
