Hey all, I would greatly appreciate any help you can provide. I'm trying to get the Bosch number off the ECU from a 1996-1997 850 T5 with a manual gearbox. It should be that large collection of numbers on the topside of the ECU. There's no 5-speed 850 Turbos in the States, so I'm at wit's end trying to find these things. -John

How did you spin the bearings and bend the rods? Adam.
[QUOTE=volvotuning]How did you spin the bearings and bend the rods? Adam.[/QUOTE] Funny story that. Kind of long, as it requires some backstory too. My car started life with an autotragic gearbox (Volvo didn't import 5-speed turbos or 5-speed Rs into the US for the 850s). When I managed to break the auto, I seized on the chance and had the car swapped over to a 5-speed using bits out of a 5-speed GLT. However, I never did get the electronics sorted out, so the ECU was freaking out and turned on all the boost/ torque limiters. The red line is my boost curve (still managed to make 223 whp/ 213 wtq on that run). So, in order to have much if any go, I usually need to be rather high in the powerband. I was bombing down a local canyon with some mates, and coming around a rather tight series of rapidly decending switchbacks at the top of 2nd (doing about 60-65 mph, 6000-6500 rpm) when I seem to have run the pickup dry for a second (or the oil pump wasn't up to par - not sure). I didn't notice for another minute, when I clued into the noise of the rods knocking the block and the bearings eating themselves. I managed to roll home, where the car has been sitting for the last 3 months while I get the replacement engine ready for install. Adding insult to injury, I had just changed the oil not 100 miles previously (and yes, there was enough oil). Before I really start to push the new engine, I'm adding a 2 or 3 qt. oil accumulator, oil pressure gauge and oil temperature gauge. Hopefully that and a full set of fresh seals all around will keep the new beast running in good stead.
