Corsa Utility 1.7dti Turbo Replacement

[OnePostWonder]

Hi,
I'm looking to buy a Corsa Bakkie but think the turbo has gone. Can some place like SAC replace the broken turbo with a aftermarket turbo? Any idea what the approximate cost will be?

I'm not really clued up about turbo's, so your help will be appreciated

Sure they can. If you want years of trouble and to pay tens of thousands of rands.

If I have to be 100% honest with you I'd just get rid of that engine, Opel doesn't do diesel well (and I'd consider myself and Opel fan). Rather fit a 2l (SOHC or DOHC) or 1.8 DOHC engine if you really need the extra torque.

Give Precision Auto Tuning (Johannesburg) or Motorcade Motor Sport (Cape Town) a call, in terms of Opel those are the guys who know what they are talking about and what to do, SAC are just a bunch of amateurs.

Opel doesnt do diesel at all. They all come from Isuzu. The little 1.7DTI comes from an Isuzu Plant in Poland ( its all on wikipedia ).

Aftermarket turbo will have to be one that made for the engine as you have a very tight fit to get it into ( right infront between radiator and engine block )

No, you can fit any Turbo. The radiator can be moved back It's common practice when fitting a 2litre Turbo or V6 Bi-Turbo to the Corsa.

Just been to SAC (they're the only place close to me I know of, I'll take the car to another place to do the work)

What the guy basically said is that you can't test a turbo without taking it apart (is this true?), and a replacement would cost in the region of R15k to R23k. The problem with the turbo is once it kicks in (+- 2500 rpm) it sounds like a VW Golf with the air filter removed and the car bogs down. The bogging down may be turbo lag, but with my foot to the floor I can't feel the turbo kicking in.

Another question... can a bigger turbo be fitted without redoing the engine? Not a monster of a turbo, just a little bigger one

Where are you located? I'm telling you now, on the Opel Owners Forum MANY people have gotten burned by SAC. You'll find some people here also, they are hellishly expensive and they don't know what they are doing.

Don't know that engine, no idea. May be possible, those engines aren't very reliable to begin with (at least not from what I've heard), so I'd ask someone who really knows before trying anything of that sort!

Kicks in at 2500RPM?? That's 50% through the rev range for a diesel. It should start spooling up at about 1300rpm and you should feel it reaching boost threshold at about 1600RPM. At 1800-2000RPM it should be at full tilt giving max torque.

My advice: buy something else or another Corsa Diesel.

BTW, turbo-lag is the time a turbo takes to rebuild boost pressure between gear changes. The point in the rev-range where it starts providing boost is called the boost threshold.

I'm close to Vanderbijlpark, and I don't think they'll let me take the car to JHB

Think I'm going to look for another car, even though this one was quite nice

Agreed, come to think of it, the R23K he is paying for the Turbo is about the Corsa B Diesels worth and 1/3 of the Corsa C Diesels worth. At that price you could have a 2litre engine fitted, gearbox, engine, management and all (not at SAC obviously).

haha don't think my dad will go for an engine swap, that's why I was insisting on replacing the turbo
