HI
I need some help with a 88 Porsche 944S. I bought this car back in October 2010 from a co worker. It has a crack head where the timing chain tersioner hooks to the head. The old owner got rid of the ternsioner. It is a 16 valve. Here is my idea on this car. It has the 2.5L block. I thought about buying a signal over head cam cylinder head and put it on my car. I read somewhere it could be done. I know I would have to change the DME and the wiring harness. The car sat in a garage for over 10 years. I do all my own mechanic work. What do you guys think or can it be done?

Thank You
