Mike, it doesn't. its a fixed housing non-VGT non-wastegated. after driving the turbo the exhaust drives the axial turbine.

see the turbine housing is smaller than the HT3B that I got from Tate that I used in my twins. and the hot housing is easily a 1/3 of the physical size of the HT4C - 28 that I used in the beginning. the compressor inducer is in the high 60's I think. that was with a tape measure and eyeballing it was about 2.75". I'll measure more accurately later thought.

 

looks to be a 68/71/13 HX55.

the 13 is cast in the housing. but 13? odd number? I dunno, thats what is says though.

would that be too big too light? hows driveability on a 68 mm charger on a 12v? how much fuel would a guy need.

 

I see it has been almost a year and maybe you found out what you needed to know but in case you didn't that has a 11cm ex hsg. 71mm ex wheel and 65mm MFS (machined from solid) compressor wheel. I've had the same thought for an upgrade on my 02.

 

AWESOME. I never did find out the specs. thats good to hear. seems like a big tight charger. theyre still on the shelf at work. I can get one anytime. I just haven't bought it yet.
