Engine #1 - Last year's race engine. The cylinders rusted due to water left from the blown head gasket at Iowa. After the engine failure at BIR, which resulted in a damaged crankshaft, Hanover European provided a 2.1L short block which is the basic engine we ran at Iowa (block B, red), with the head and other bits from the BIR engine (block A, blue). Due to the rusted cylinders in block B, the plan is to use Block A from the BIR engine with pistons & crank from the Iowa engine (are you following all of this?).
I attempted to clean the rust from the cylinder walls of Block B in order to remove the pistons to build a new race engine. The head from this engine still needs to be resurfaced, presuming it warped after overheating. Instead, it will get the head from engine #2, which has recently had a full valve job.
Engine #2 - from the 1992 900S parts car. The cylinders in this block (painted light blue) are pretty worn, though with no scoring or scratching. It appears something once failed in the #3 cylinder as there is some damage to that piston. There is a pretty good ridge at the top of each cylinder. Ideally this engine should be re-bored and get new pistons. I will probably put it back together as is for the time being as it ran when it was removed from the car. Hopefully we won't need to use it.
The head from this engine has had a valve job and resurfacing at Midwest Engine Rebuilders in Duluth, so will go on the race engine.
Engine #3 - from the 1993 900S A/T - Good compression, so I am not removing the head from this engine. Will check the timing chain and the rod and main bearings, but expect everything will check out OK. This engine has been off the gearbox once upon a time, but not sure why. It may have already been rebuilt, or the automatic transmission may have been rebuilt.
Either way, we have two engines for the 14-hour race at BIR. The 5-speed gearbox from the '92 900S parts car will be in the race car. If I have time, there is another 5-speed gearbox in one of the cars in the yard, but it will take a day to remove it.
