TunerToys will set me up with a new CHRA ready-to-go. BUT - when I went to confirm my compressor wheel with measurements, it didn't jive with anything I found.

I was using this chart (scroll half way down). The inducer measures 2.13" - which means it's too big for a 50 trim (even with the wear on the blades) - leaving the 54 and 57 trim. Where it gets confusing is measuring the exducer. This wheel measures 3.19" - "off the charts" for T4 compressors. I'm just guessing, but maybe this is something done by another manufacturer because at a near the 2.95" diameter the back to blade peak is the same on both wheels. That said, the 57 trim/chinacharger wheel will NOT fit in my current housing.

Pics below are of it on the right next a chinacharger (left) wheel that was claimed to be a 57 trim. It too has damage, but measures 2.19" at the inducer (too big to be anything but a 57) and smack on at 2.95" for the exducer. The biggest difference is the contrast in height/depth from back to blade tip/top.

Think it's a safe bet on the 54 trim based on inducer measurements and just ignore the overall back diameter?

Well you've got me stumped!

that's not a good sign maybe I'll just send them the wheel and housing. I've got my old chinacharger housing too, which would do a 57 wheel, but it nasty rough on the inside and needs bend welded on.

that's where most of the alltrac.net data came from I think.

The closest thing I can find is either a

GT40 compressor wheel (2.28 I / 3.23 E)

or a TO4S 60trim (2.32 I / 3.22 E)

Ya, I looked at all of those also. Try calling Corky tomorrow... He might know where that 81 MM compressor is from.

damn- the inducer is too small to be either of those. The "57" trim wheel at 2.19" (from the china charger) won't even fit in this wheel's housing. The the blades at the inducer hit the housing walls.

did you look through the turbo diesel charts?

I don't think the garrett or turbonetics specify whether a turbo is for diesel or gas.

I think you'd be looking for a Holset hx35 or hx40 wheel....

the H1E:
Assembly P/N 3530994
Compressor inducer: 58.05mm
Compressor exducer: 81.57mm


getting closer.....


I know that holset and borg-warner both use those extended tipped inducers....and why they flow better than garrett.

Turbonetics 600hk turbo
Turbonetics turbo från KRB

Kompressor In: 54mm Ut: 81mm
Turbin In: 71mm Ut: 62mm
A/R 0,83 på avgasdel


those numbers are right on the money....same brand turbo right? too bad that doesnt help you figure out what wheel it is, but you could try calling turbonetics up and seeing if they can source it.

I skimmed the chart I have, and didn't find anything really matching it within Garrett specs.
2.13" - 54.10mm
3.19" - 81mm

Damn Brainy - good find, but alas the 2.13" is post damage so it was larger than that- maybe 2.17.

The most practical/economical solution at this point is to just go with a garrett 57 trim and use my 57 trim housing. Yeah, I'm think inside the box.

well if it were 56mm-58mm then id say the holset wheel. but yeah, pretty damn large for a stage I t3 turbine....
