[914 again]

Just picked up a 914 after 15 years since my last one.

I bought it on a whim and want to tinker with it.

First question to any gurus out there. How do I time this bloody thing?
The engine is supposed to be a 2.0 but I don't know if it is a bored out 1.8L or a "real" 2.0 which I think would affect how I set the timing. Would it be best to find the engine numbers and read them off? If so where are they hiding?
THe engine is not the original so pulling it off the chassis wouldn't help.

Second question what is the best 914 shop for rebuilds and basic maintenance in Southern Calif? I plan to tinker with it but for the big stuff and thing I don't trust myself with I will leave it to the pros.

Thanks for the input
