Back on my TT engine project........

The base of the project is my original engine, the one I've got on my car when I bought it....a 930 turbo S motor.


I got 3.5 Mahle pistons/cylinders and I had to machine the engine block to fit the cylinders.....diameter 100mm





and somme more improvement to help air flow inside the block....





I also got 962 heads from Paul Weir since 4 years.....chambers and outlets have been polished and now, I have to find a solution to adapt heads on cylinders with or without gaskets.....I need some advice......










One of my thoughts is the following one.......









Does someone have some experience and feedback with that kind of assembly...?.....and with gaskets or not....?


P.S.: basic ratio for the pistons/cylinders is 7:1 and of course, it will change a little bit if I machine the cylinders heads.....but, as it's a turbo engine......

Serge,

Great car. The heads look to be cut for a retaining ring. This is commonly called a flame ring. It helps seal the combustion chamber against leakage when high boost pressure leads to intense combustion pressure.

I suggest you find a machine shop that can cut the cylinder mating surfaces to match. This usually requires custom flame rings to be cut at the same time. This is a process exactly as you illustrated.

You might want to check with Mike at MBEnginneering in the UK. He is a contributor on this board. He would be relatively local and capable of the machine work.

Nice video. I've been around Le Mans.. (On my PlayStation3 )

You certainly are a 'gentleman driver', Serge.. I wouldn't have put up with that Boxster and White 911S for as long as you did! (I'd have shown them my HUGE, over-sized, rear wing.. Getting smaller and smaller )

Anyway, hope you got the 935 going again..

Serge, I've watched your videos. Your car rouge, she is magnificent.

But you make James May ("Captain Slow") look like Ayrton Senna - please, show me a video where the engine goes above 3,000RPM!

That is really odd! The case seems repairable but the hole is so clean it's almost as from a bullet.

Oh man...I'll say it's a loose/broken rod bolt punching through the case. What a stinkin' bummer! I hope the damage is minimal.
