Very surprised they were able to offload Opel, not that I know intimately the problems people are talking about but it's the same situation GM was in when trying to sell Saab or Saturn; the 'division' technology was so tightly integrated with their platform development for all divisions that they would be have to give away current technology in order to have something to actually sell, and with Saab and Saturn they weren't willing to do that. In the end when you have all nameplates running the same undercarriage you really have nothing to sell at all. It's not like you could sell Saab with old tooling, it wouldn't be worth anything, same goes with Opel, what are the last gen Opel models really worth as new cars? Not much. This doesn't even address the engines but it's the same thing, what are you going to power them with if you don't won't sell them the engine because it's your mainline technology in your other cars? If you look at this whole last round of auto makers scrambling to buy other auto makers it was a huge waste of time / money. A lot of people made really good money on the M&A from these but in the end all the auto makers took a bath. I'd like to ask Ford how well it made out after it overhauled Jaguar and then sold it off? I doubt that it did all that well, otoh at least there was something to sell. Not to get off-topic but US Govt had no biz subsidizing GM through all this past downturn, GM was in that predicament of their own making and the next one will be too. They just flounder from one problem to the next, all the divisions are now basically gone, I give them a decade and they'll either split into smaller units or go away. Not that I think Tesla or their ilk are the future, they would be gone if not for the Govt subsidy as well. Steve

Is there any way you can record a video of the noise? Without more information it's going to be hard to diagnose much about it. Steve

While I agree that PSA has some very good diesel tech the problem is that GM tends to destroy everything it touches. I wonder where the $ came from to invest? Seems to me it still hasn't paid back all the bailout bux yet.

Just get one of these (XD3TE)..it'll give you 110hp (some references say 115hp). The intercooler is a good idea even if it isn't factory. There just isn't much to be done to mechanical diesel FI systems or IDI engines. There are larger pump components available but you'll have to do the research on that. It might pay to figure out how large your existing pump is and see about having a custom pump built for it...or building one yourself. There are also different nozzles available for the injectors that might add a little umph to it. There's a lot of good IP info on the VW sites, like Turbodiesel.com, and the Benz diesel guys often discuss IP mods on Superturbodiesel.com IIRC. Since a lot of these old IDI diesel engines share components there's a wide variety of stuff out there to pick from. good luck!
