Turbo Improvements?

[Profpinz]

G'Day All,

I've been following this Forum for some time and gained some interesting insight into the D24TIC engine, but it's come to the time when I need to start rebuilding the motor and as I haven't got a turbo at present (it was missing off the motor) I have the opportunity to either go standard or upgrade.

Now first off I should say that I DON'T have a Volvo, rather an Austrian 718 Steyr Puch Pinzgauer. These "second generation" Pinzgauers used the VW D24T or TIC motor from 1985 to early 2000 after which time the VW 2.5 5 cylinder was fitted.

My 718 has a D24TIC which originally had a Garret 454007-1 T3 (VW 072145703B) fitted.

My options are to buy an old T3 of the same type and rebuild it (or buy a refurbed unit), fit a upgraded unit (a T4 possibly, but this is the main area that I'm open to suggestions) or there is a company in Europe selling Variable Geometry Turbo's for the vehicle (a pretty expensive option I'm guessing).....I'm unsure what the best options are given that I want a reliable, and relatively economical vehicle fuel wise (it will be used for lond distance touring).

My knowledge of both diesels and turbo's (never having rebuilt vehicles with either before...air-cooled petrols are my forte 8-)) is minimal so I though you guys who obviously know far more about thses things than I do might be able to give me some guidance.

Thanks in advance.

I would stick with the stock size turbo or a small trim T3 to keep the low end spool up and low end torque characteristics... A larger turbo will have more flow potential and be able to push more boost and make more power up top, but in a heavy vehicle thats going to be used for what your saying, the smaller turbo will suit your use better. Fit a low restriction exhaust of some kind, and turn up the pump slightly, install some GTD or 293 injectors and you will be happy with the performance I would expect. Good luck with the build and by all means post up some pictures of this beast!

Thanks for the information....much appreciated!
I think given your advice and my research, a standard T3 is the way to go.
A low restriction exhaust is definitely on the cards and given the vehicles engine/driveline layout quite a simple thing to do. A virtually straight 800mm pipe links the turbo to the muffler which then exits out to the side. A nice 50-62 mm diameter exhaust should suffice.

As regards the injectors my motor has 068130202G units fitted .... I'II have to check how these compare to those you suggested.

Below are a few pics of the vehicle....initially as it was purchased then a few of the motor of course and one of removing the platform from the driveline.....the Pinzgauer has a backbone chassis unique to all but a few vehicle manufacturers.
The beige Pinzgauer is not mine but what my 718 will look like after the rebuild.

A few more pics of the rebuild....First off, moving the "new" Pinny in behind my previous project (it took 13 years to restore the 712....it has a 4 cylinder, 2.7 litre air-cooled petrol which has individual cylinders and cylinder heads).
Then lifting off the platform and getting the chassis components back from the zinc plater/powdercoater.
The last pic is of the motor bottom end of course....I had the oil tested and all was OK with the motor and a "plasti guage" inspection showed all was within spec so now I just have to look at the top end, turbo etc. I intend to fully clean and rebuild the whole motor, but it's nice to know I don't have to rebuild/replace, bottom end componentry.

The oil pan is a VW one that's funny.
heat shields ,accessories like the steering pump,fuel filter bracket are VW too.

except the cold start device.


Very nice build

is it stock or you mixed parts ?

[Profpinz]

As stock as I can make it
