so - after many attempts - seems a battery surge got it to start today. hopefully it'll start tomorrow! I think it may very well just have been the battery. hope so.
Do you have anymore info.Was anything else replaced?
big explosion when start
I’ve been working on a big project for the Volvo this winter. The plan was to solve some of my drivetrain weaknesses by installing a stronger, faster shifting automatic. В As the power levels have gone up over the last couple years, I began having problems with clutches lasting. I always had to keep the boost at a level that would not cause the clutch to slip in the higher gears. The engine was always capable of more power than I was able to put down to the ground. In addition to the clutch problem, The BMW Getrag manual trans I was using was never a great shifting transmission. They are very strong, but not the most graceful shifting gearboxes. Since I have been more interested in drag racing over the last couple years and needed something stronger to boot, I decided to make an automatic GM transmission part of the drag/street package. This should be a goodВ modification for improving performance in the 1/4 mile and won’t affect the street driveability at all. This transmission has some nice fuel saving features like an overdrive 4th gear, and lockup torque converter. It will still be street driveable.
I had to source a couple key parts to make the Volvo 4 cylinder engine bolt to then GM automatic. First I would need an adapter plate that would bolt the block and transmission together. This plate is available from KL Racing in Sweden, though I had a custom made plate done in the US by a fellow Volvo club member. The bellhousing adapter is a piece of 5/16″ plate steel with bolt holes for the volvo block, and GM transmission. It also has guide pins and holes that align the parts together precisely. Here is a picture of the plate:
Having the engine bolted to the block is only half of the problem. The torque converter also needs to be bolted to the engine’s crankshaft to before the car will be going anywhere. В An adapter or a custom flywheel would have to be made to do this job. I wanted to use the Volvo flex plate if possible because it has the starter teeth on its perimeter and bolts to the crankshaft already. It would be nice if the enter package could be bolted together in anybody’s garage in the case that someone might want a copy of these parts that I was having made. В Another good reason for the Volvo flywheel is that it would let me use the Volvo starter in the stock location. Some important features of this part would have to be precise alignment of the torque converter and crankshaft center lines. It all has to be balanced. The centering snout of the converter would need a pocket to fit into. And the adapter plate would need a snout to align it to the crankshaft. Here is what I came up with:
