did a search and found a bunch of stuff about computer codes. i want to find out what engine is in my 95 ssei parts car.

What do you mean by 'what engine'??? the '95 SSEi had a Series 1 L67 motor with updated rotor coatings in the supercharger. I do not know what other changes were made along the way through the S1 life cycle, but I'm sure others will know more.

so the 95 and 93 ssei'* both have a L-67.

Yes, but the SC and TB are a little different, better design. To use them, you'd need a Mini AFC for your 93. Otherwise, swap away.

to use the 95 motor, you can also just use the bottom end of the 95 motor and use your TB and Supercharger. This way there is no need for the mini afc.
