FTP lights

Ports 5th 6th, im not to sure about this one yet

my car is a 1991 what can i do?

 

nobody?

 

FTP lights are... well they're lenses..
the 5th and 6th ports (aux ports) should be properly functioning.
other than that, not too much outside the ordinary until you break the block open.
you may come across intake manifold porting and throttle body porting. its hard to get much out of an n/a without getting real serious and spending a lot (similar to other n/a small-litre engines).

 

Read these and read these well before you make anymore posts.
