If it's 86-88, then it'll say "13B Injection" on the top of the throttle body. If it's 89-91, it doesn't say that.

I'm sorry that I couldn't be more descriptive...I haven't seen a N/A engine in a while.

the S4 ones (86-88) the writing is black...and is sunken in, in the metal. --_-- S5's __--__

The _ is the writing :P and the -- is the writing on the new blocks.....if you can understand :P

The S4 ones have writing and heat sink ridges on the dynamic chamber, the S5 ones only have writing.

The S4 has a mechanical OMP, the S5 is electrical.
