Smart ForTwo

Does anyone own a Smart ForTwo 700cc petrol turbo or has driven one?

 

I'm trying to diagnose a turbo issue on one at the moment. Before when driving you could feel the turbo come in strongly at around 2-3k rpm in the first 3 gears then once in 4th it would overboost and the ECU would go into limp home mode.

 

I've found that some clown had mixed up some of the piping between the boost solenoid and the wastegate actuator, which from what I can tell completely disabled the wastegate. I've put all the pipes back to stock and taken it for a test drive but now don't feel any surge from the turbo, just linear power delivery through the rev range.

 

The problem is that I've never driven one before so not sure how they are suppose to perform, I expected with the wastegate now working that it wouldn't pull as strongly but I'd have expected to feel the turbo coming online.

 

Next step is to fit a boost gauge to check it is making positive boost. In the meantime if anyone has driven one could you describe the performance/power delivery?

All sorted an IC pipe had blown off, reattached it and the turbo is definitely kicking in, it's also no longer overboosting and going into limp home mode so job done. Now to refit all the plastic bodywork bits back on!

Something went pop on my Mum's Smart today, still running but loss of power and white smoke billowing out of the exhaust. B*ll*x!! engine out job me thinks :(

 

Anyone got a spare bike engine I can shove into it!

My lack of mechanical sympathy has reached an all time low, one dead Smart ForTwo Garrett GT12 turbo :)

Oooh that has chewed something up...

 

The whole shaft is rattling around loose inside the housing, looks like the bearings went and the corners of the compressor have smashed into the housing.

 

The turbo's are usually easy to find about though... I can ask the guys I was getting parts off if need be.

 

Cheers Gav, I think I have a source for a replacement, if I get stuck I'll give you a shout.

Is the turbine housing cast as one piece with the manifold? Looks expensive, how much would they rush you for a new one? Still say flog it and get them a Yaris or an IQ ;)

 

Yes the exhaust housing and manifold are one piece, got a replacement second hand one sorted I think.

 

It was one of my Dad's inspired Ebay purchases :rolleyes: Definitely be flogging it if I can remember how all these bits go back together :) So much for German engineering, definitely not impressed :thumbdown:
