1990 Porsche 928 GT, fresh timing belt maintenace

I have owned this 928 since 2007 and have done, r had done, ll maintenance required.
I had a complete A/C refresh to R34 using a Griffiths kit.
I just did the timing belt refresh in 2015 for the second time since I purchased the car.
I have replaced all sensors, acuum hoses, tc. in the intake manifold area.
Everything was working on the car when it was put in storage for this winter.
I recently purchased a parts car, hat could be included in the deal, f desired. The parts car is a complete 1987 S4, ut with automatic, nd is drive-able itself. It could be used to provide any hard part that fails, nd has some newer parts on it as well.
I want to put more time, nd money, n my other cars, nd don't use this much.
