Civic EG

as i am new to this i ask patience and not to laugh as this may be a stupid question but i have a d13 carb model and i was wondering is there any way i can just swap out the motor and gearbox to something more powerful without
changing the loom or wiring at all or altering it like i have seen guys splice looms but this aint for me

youll need an ecu that can run whatever you get, and if you go vtec youll have to wire it in, but its simple and only uses two wires. That is...pretty much the extent of it.

Dont feel bad about asking questions. Ive discovered this forum isnt like most forums.
