Engine values
 

Whats a fair value of 3.6 complete with all the cables, computer, muffler, etc. out of a running car?

The same but a 3.0?

What is the best investment for the money?

Which 3.6L?

1) 964 3.6L
2) 993 NON Vram 3.6L
3) 993 Vram 3.6L
4) 996 3.6l (;) )

All comes down to condition (mileage) and if stock or not.

The first 2 are likely $6-9k
A Vram a bit more

A stock 3.0L with CIS is maybe $4-5K

Clearly a newer (stock) motor will provide more power and torque, but will need a lot more "adaptor" bits to fit into an SC.

Steve Timmins (Not sure of his website -I think he lives in Delaware or South NJ) does 3.6l conversion for various cars and has a rough price list of the work and parts needed for such a conversion. Might be a helpful reference.

Thank you guys. I'm in the middle of a possible trade. Now I feel more comfortable. Engine is a 993 non vram. It is installed in the donor car right now and comes complete out of it. Mine is a 1978 3.0 also complete and installed in my car.
Lets see how much is the turn around($$$)
