If i engine swap on the S13. And swap it the S15 (SR) engine. Is it possible to do that. Cuz the S15 (SR) looks different. But would it fit actually into the fit. Or there mod's to do.

what the different from tachometer and speedometer?

I think you might be getting a little ahead of your self. :smile:

waaaaay ahead of himself.

dayyyyyummmm, s15 sr???? you need to begin research, i know of one person who's done it in a s14. but no matter, start researching before you ask questions. to start off your research, you need cash.
