I recently picked up a turbo for my e30 but I decided I want to go bigger. I know this much:
The little garrett badge riveted to the back of the turbo says:
No.
G.F. 466016 2
NO. S. OF0108 H
The first o in the last one might be a Q, but It’s hard to tell.
Stamped on the hot side is: 430567111
on a lower portion of the hotside is also stamped:
430931/1
H4 <>10
9-6
The turbo is also .42, .48ar. internally gated, t3 flanged and ball bearing.
Any help is much appreciated. Thanks!
no idea did you try google’n the serial number? or any of the numbers for that fact?
you have to cross refference the serial number stamped on it with a book or online database for garret turbos. best bet is to call garrett themselves and ask, or call inn-tune or swerve motorsports to see if they can run the number for ya.
my thoughts exactly. he spend over a grand on the “kit” too
I knew I was going to upgrade before I received it anyways so I didn’t see much point in caring what it was other than to sell it and put the cash towards something I actually give a fuck about.
Quick call to garrett reveals that you have a TB0324 turbo. Oem on 83-86 BMW 524’s
And not to be rude, But Paul from swerve is not the guy to go to if you have an actual tech question
.02 
Thank you sir 
have a pic? its probably a standard turbine and a 50 trim T3 compressor wheel. good to ~270whp if you max it out and beyond.
