exhaust housing info

[dodgeshadowchik]

i seem to have a "bastard" T3 turbo. i'm in the process of trying to find it the correct housing so i can use it on my 3.0L. what confuses me is that is seems that one or more housings will work on certain trims. i have a garrett turbo with the .48 a/r housing and the wheel does not fit. i currently aquired a .63 a/r housing, i'm hoping this will work.

i went to garret's site and accoring to their formulas, it apprears the housing i have is about a 50 or 60 a/r. (couln't get a very accurate reading as the housing is really odd shaped) i believe the housing if from a VW or porshe from the looks of it.

any insite on how to select a housing or find one would be apprecaited!

If the exhaust wheel does not if in the housing, it is most likly not a stg. I wheel. You should measure the inducer and exducer dia. and compare that to the wheel dia. chart that I can never manage to find. That will tell you what stage wheel you have, and then you can match up a turbine housing to it.

there it is - stage 1 through 5

Like cordes said, measure the inducer and exducer size properly, and compare. If you need a stage2 (if your turbine wheel doesn't fit the housing you just got) I have a chryco stage 2 from turbonetics, and I'm looking to trade for a chryco stage 1 .63 housing :D

ok, this is weird. the exducer diameter was below the stage one specs of 1.916", however the major diameter was just under what the stage 2 spec was of 2.555". :confused: :confused: :confused:

i truly think this is one oddball turbo, maybe made to a manufactor's specs? think i'd be better off just getting new wheels for it since i have the housings now.... :/

thanks for the help! if you have any other ideas, let me know!

and i know it's a t-3, at least on the compressor side because it is stamped "T3" has Garrett Airreaserch all over the thing.

It could be a clipped wheel. Post a pic if you can. Some of the guys can tell if it is a stage II or III wheel by the angle of the veins.

ok, cool. i'll see if i can get a pic of it and post it tomorrow. just out of curiosity, why would someone want a clipped wheel?

I had a stage II wheel in a .48 housing that was clipped. It came with the car, but it was clipped to allow for more exhaust flow in the tiny housing. I believe some people claim it decreases spool time due to less rotational mass, but I don't know too much about those claims.

ok, here are some pics of the wheel in question. thanks for and help! sorry about the focus. the camera doesn't seem to like close ups.

Here is the only pic I have of my stage II turbine wheel right now. It is clipped. Yours does not look like it is clipped to me, and I cant really tell what stage it is. Try measuring again, and see if you get a different dia on that exducer.

The stage 3 turbine has no webbing on the back, so it's gotta be a stage 2.
