I am the proud owner of a '91 Civic std.

Thats right, the really really really slow civic with a 4-spd.

I wanted to know what my options are with this car. I wanted to do some solo racing with it however, it's classed right next to the si. So, I was looking into csp and then remembered something about SP cars and IT being set up very similiar.

Whatever direction I go I don't want to eliminate the option of club racing this car one day in the future. So, Is IT a good place for this car or is there another class I should be thinking about?

Am I able to swap in a d16 si motor and tranny and go from there?

Any help would be great!
