I've just done some searching on the net to find out more about my engine number.
Engine number:
63D8174
I found the following page, which has a very comprehensive list of engine number descriptions:
https://issuu.com/dr.culata/docs/porsche_engine_codes/15%2063D8174
It says my car is a Japanese 1983 911 SC
It says that my engine is 132 Kw, 179hp and 3.0L engine.
I was of the understanding that 1983 engines were supposed to be around 204hp?
When I look at the other 1983 911SC engines that aren't Japanese models - they ARE the 204hp or 150kw - also 3.0 engine.
What exactly would it be about the engines that is different that would be 25 less horse power? Especially since they are both built on a 3.0L motor.
Does anybody know if this is something to do with restrictions Japan might have had on emissions output? Hence, something in the motor is causing that 25hp restriction?
Ultimately, I guess my question is, is there something that can easily be removed/installed/changed in the engine setup that will bring those ponies back to life?
Thanks team!
