I have a 1978 911 sc targa and the engine is beat... over 210.000 miles on it and we are replaceing it... (im from the us so im a noob haha)
i want to hopefully put a newer porsche engine or any kind of engine that is fast that will easily fit into it...
Please let me know if there is anything, and if not, a place where i can get a new engine for it.

 

If it were me, I would swap in a 3.2L from a mid to late 80's carrera. Make sure you get the brain box as well.
