Cam Angle Sensor, alternator, oil supply hose replaced.
Great car, very fun to drive. If you drop it an inch or so it handles like it's on rails with the AWD. Turbo is a bit small, but upgrades are available. Car is way ahead of it's time for a '91.
About half a year ago I purchase a ’91 Isuzu Impulse. It had been sitting for almost 7 years. The turbo was taken out and lost while being rebuilt. So finding a replacement resulted in a trip to Ft. Worth Texas. Soon we realized that the crankshaft needed replacement along with a decision to rebuild the engine. Most of the parts were easily found through the dealership, which I might add were very helpful. Our biggest problem was finding the right main and rod bearings. Not only was size an issue, but for the main bearings need oil injector holes. Just so happens that every company I researched discontinued the manufacturing of these bearings. We found a local machine shop to custom drill holes into the mains for the injectors. I was wondering if anyone else had this problem and if so how did they get around it.
Overall its a great car that handles like a dream and was way ahead of its time.
Rod and main bearings are available. A quick check and I found that rockauto. com has them listed for sale.
