What kind of garret is this?! Fitment for 3b?

[Klaufi]

Howdy,
Got this Garret turbo i got for cheap (A hug and a smile)
Can any1 tell me what kind this is and if it's suitable for my 3b?

Can i get it from you for a much bigger hug? ;-)

My garrett from is .48 on the turbine side (like yours) but .67 on the turbo side (exhaust) and yours is .53

I'm not sure what a smaller ratio would do on the exhaust, but my guest is it would work. Your are missing some parts, and the flange is 3 bolts, so you would need a adapter plate. The waste gate actuator..etc...

Here are tons of picture of mine and the installation
Turbo installation

Turbomaster shows that model number being a GT1752 from a nissan RD28.
That's a 2.8 litre 6 cylinder diesel which revs to almost 5000rpm.

Yes it'll be a good turbo for a 3B, it's on the smaller side so you'll get lots of low end boost and not quite as much top end power.

Is there anything stamped into the flat section on the compressor cover?

Yes I think that will work for the 3B, based on what other's here have said about A/R numbers that is. You'll need to either make an adapter plate for the exhaust manifold (or a custom manifold if you can weld) and you'll have to clock it (turn the compressor side) so that the inlet tube will be easier to mate with the turbo.

Also make sure the oil return is pointed downward as close to vertical as possible. All things to think about when installing a turbo.

The second thing you should buy for your install is a Pyrometer. A must if you want to make sure you don't overheat your combustion chamber and do serious damage to your engine (read re-build). Summit racing has a GREAT deal on a VDO pyrometer for $99 and it comes with the k-type thermocouple.

Keep us posted and if you don't mind add more pictures of your progress.

Huh? smaller side of what? it's a .48/.53. Seems to me it would be on the larger end of being a perfect match but still quite usable.

The A/R ratio by itself means very little.

Consider this, two turbos with the same A/R ratios, but one has wheels which are twice the size of the other.
They will not spool at anywhere near the same point.

To give you an idea of equivalence, a T3 with 60mm wheels and an exhaust A/R of 0.42 will spool up at a similar time to a T25 (53mm wheel) with a 0.49 exhaust A/R.

I'm clear on the wheels. I understand how they work.

what size is it? I must have missed it. The pics are big on my little laptop and I have to scroll to the side . Even if it's a 50 wheel I think that's better suited for a 3b than a 60 wheel.

Even if it's a 50 it's more suited to a 3b for overall performance. I still don't see how this turbo is "on the smaller side"? It's on the larger side if we map it, no?

As far as I can work out, the GT17's use a similar size wheel to the GT15's. That's around 41mm OD.
Your sig says you've got a TDI, which type? Your TDI probably has a similar size turbo.

Fair enough, I assumed by looking at it that it was a 50 wheel. If it's a 40, then smaller side applies.

I have the VE 1.9l
