I've had both and the non turbo and i would'nt say the vauxhall engines are "slow" just not quite as fast as the isuzu.
turbos on the front of the isuzu too, sure its on the back of the GM lump
Isuzu diesel engine. Though not all turbo diesels have Turbo written on the top, some have just diesel, but the writing is black and in the same style as the red Turbo. The earlier versions of this engine have a black plastic plenum type box/intake at the back, where the metal one is in this pic.
Isuzu's seem to be better. Alternators are expensive however... And if that goes, it causes all sorts of issues with the glow plug light... Although, I'm no expert on anything with a diesel engine!!
Yes, the Alternator and starter motor are both expensive items to replace on these engines. There are also two types of each as well.
some starters have a nose cone on them others dont
some alternators have a square plug in the side of them for the rev counter and others have a round plug on the back for the rev counter. Both have a vacuum pump on the back for the brake servo
However when my alternator died, it was merely the voltage regulator and it would flatten the battery after a few days, otherwise the glowplugs worked as normal

Yeah its the gm diesels that have diesel written on the top, and iirc the diesel thats written on the gm lumps is embossed whereas on the isuzu ones its a sticker on the vast majority of them
GM diesels do have DIESEL written on them in white, and they resemble the look of the 8v petrol engines. However what I was referring to here is that some Turbo Isuzu engines look like the non turbo Isuzu engines due to the Sticker still saying Diesel on it rather than Turbo. Recently there was a GLS TDS (same as mine on ebay) that just had Diesel on the rocker cover, these engines are Turbo'ed though
yeah mate, not to worry though
here is an ebay link if you don't believe me. (you can see in the pic, the pipework that runs down to the intercooler. The car is identicle to mine though, right down to the colour, well less the dents, lo

How quick are the Isuzus? Which models got which engine?
Never tested acceleration on mine. I am pretty sure that the Isuzu engine was fitted to Astra's throughout their life and where also fitted to Nova's. I am pretty sure that they where fitted to most models in the range, from LS up to the CD models. If you are after just the engine, then I know for definite you will find them in the TDS models (mine is a GLS TDS) they where also fitted to Corsa's and Combo vans too
