Haven’t posted in a while…too busy working on stuff!
Here are some pics of the latest track car. Got to show it off at 944fest
3l dry sump with many bells and whistles

The only sleeving I will do is the MID system....which is now so expensive that it only make sense for full on racecars, 'regular' sleeves can be trouble prone for most builders.
And now Millenium Technologies just had a fire in their shop delaying production by a month.

Alusil has very good ring wear characteristics but very bad strength for ‘foreign objects’ like carbon. Aulsil has been around for 30+ years and I have never taken apart a turbo block with out some degree of scoring.
Nikasil is much harder and you can overbore the block and coat it back to exactly ...

when doing a clutch job it can be bolted in place of the slave cylinder and the center bolt screws in to open up the pressure plate so that the torque tube will slip In to place effortlessly. Total cost…about 50 cents!

Made many a custom 944 tools over the years. Had to use this one today, made it long time ago. Any guesses?
