Crankshaft top side bearings installed and coated with assembly lube. Went with the m113k specific crank bearings to utilize the coating they come with compared to regular m113 bearings

Crank bearings gauged and installed with assembly lube, the assembly lube smells like mint interestingly enough, im not sure what the purpose of that is. All crank bearing caps torqued to spec with new hardware. I used some loctite on the side (bolts 5 and 6) bearing cap bolts.

Here is a photo meant to depict a before and after example of lapping the aluminum engine block cylinder walls. The aluminum actually has 30% silicon content and a process using felt pads on a hone coated with alusil honing paste(the cylinder walls also get coated with the paste and regular engine oil in the process) brings forth the silicon for the piston rings to slide on. The silicon is much more durable than the aluminum alone which is part of the reason m113’s typically last a long time

Before and after example of polishing the crankshaft journals, on the left is wet-sanded up to 1500 grit, with wd40, on the right is after being pulled from the engine and cleaned with gasoline and then citrus degreaser

Here’s a mock-up of the intake manifold idea... more to come soon

Porting the turbine housings as well... there is a lot of material that can be taken off of these turbine housings even just to gasket match the port

Before exhaust porting, notice the two large and useless “bumps” on each side below the exhaust valve seat... not too mention directly under each valve seat are some pronounced ridges from the factory casting
