Help Identifying A Turbo!

[private9]

Hi All,

Bought a turbo ages ago, and I can't really remember what it is!

Was hoping someone may be able to help in identifying it!

It's a Garret turbo.

I recall it being a T4 core, something about a Sierra wheel (can't remember front or rear though!).

Rear housing says A/R 116, then DH6GA2, then M1.

Nothing on the front of the compressor cover, some random digits in the back all the way around in pairs.

Here are some pics:

Appreciate any advice anyone''s able to offer!

Thanks,

Justin.

If its a hybrid (which is seems it is), only way is to measure the wheels.

1.16 housing - its probably off a rotor with a housing like that

Yeah I thought rotor when I saw it too.

No part numbers on the centre cartridge?

+1 on the measure of wheel size. Get your verniers out and then it can be identified. Even if it's got hybrid components, it can still be estimated for power output and approximate specs.

Looks like a TA45 but unsure on the turbine inlet whether it's TA or T4. Need to measure centre of hole to centre of hole on the flange.

It looks like it has a V band flange welded on the back as well as having four dump flange bolt holes as well .

Note the compressor backplate is iron instead of aluminium so it could be from the T04S 60-1 family and modded .

Not a 60-1 compressor (409535-1) because they are 7/14 bladed , maybe T04R or TA 45 compressor on big shaft T04 turbine shaft .

Caliper measurements needed , A .

Thanks for the advice guys. I shoulda been a bit more careful with the piece of paper containing the info!!

I'll borrow a set of verniers and get some measurements.

I do recall it being a hybrid, T4 seems to ring a bell, but it's definitely bigger than your average T3/T4 hybrid.

1.16 housing - it's actually off an aftermarket turbo'd 4l Falcon - plenty of exhaust flow there!

Only markings I can find on the centre cartridge are a Y on the top, A on the bottom, and 4.5 on one of the sides.

Yep, V band flange.

Again, thanks for all the advice so far guys, much appreciated!

The XR6 turbo doesnt even run a rear housing that large, and will make over 350rwkw on a factory turbo... and its FAR from a 1.16!

My bet is the butchers turbo you have above wont get close to that marker anyhow... so with a housing that large...

... I maintain its rotor only application

No worries, thanks for your advice.

It has run 325rwkw at 20psi, through an auto with a 3000 stall - so 350 at the treads at the same boost in a manual would be a comparable figure.

But with less response than a GT35 that comes factory on the XR6-t... and GT35 will make more power!

Is definately not a win-win situation...

And im skeptical of dyno results at the best of times when people are selling stuff.

Yep, agree 100%

Definitely not ideal with that size rear housing but oh well!

As for the results, yeah I'm a sceptic too, but I saw the sheets and the rest of the hardware myself, and it all seems pretty genuine.
