The car so far has only road and dyno' miles, I took it to the Silver Flag, but unfortunately it broke a driveshaft coupling. On its return I stripped the engine and transmission to check for wear/problems, none found but took the opportunity to change the can to full roller bearing operation and make some modifications to the gearbox detents. I'm now building a second box with longer ratio's suitable for circuit use. The first box is very short making it suitable for hill climbing.
If you use a PBS head, I'd be happy to help re: set up and carb' jetting, The basic head is good, but I ported it further and re-made the valves, valve spring retainers and collets. Also to get the correct rocker arm postion due the base circle of the cam it may be necessary to shim the rocker posts.
On my head it was necessary to mod' the inlet modifold water feed, as supplied it would have leaked from the head to manifold interface if it was used as is. If you do use the head I'd be happy to forward details so you can check.

I never realy made the gearbox with the intention of selling it, I only produced it because when I built the car there were no 5 speeds in stock with the Italian companies that produce these conversions. Its now become a real passion to develop it further into a reliable and competitive part. I've dyno'ed the 1st box to check to see what power losse occurs and I'm now building a 2nd one with further mods and DLC coating to see if I've got an improvement. I'll post pictures when its complete.
The picture is of the valves I produced for the PBS head, and the car at the 2005 Silver Flag.
