This evening I got time to do a bit more to the mill. I was a little concerned about getting the block on, as the older Porsches have individual barrels so its easy to guide the piston up, but with the busa you have to do all four at once :S
Anyway, it had to be done, and unfortunately I couldn’t think of any super douper sneaky methods, if anyone knows any please let me know! So first of all I got all four pistons on, making sure not to drop the circlips down into the bottom end!
Unfortunately I only ended up getting a single day this weekend on the engine, but I suppose thats life! First up was to build up the crank. Again all this is like normal, and the rod bolts seemed pretty consistent, which is a relief!!! There are two methods of tightening rod bolts. You can either just do them up to a specific torque, or you can stretch them a certain amount. Stretching them gives a more accurate result, but takes a bot longer as you have to measure them before, and then a few times whilst tightening them up, but I decided to use the stretch method as it gives a better result.
So after much measuring the small incremental torque adjustments the crank was built up.
