I'm currently driving an 81 KE55 rolla with the corona 2S-C in it. I know it's not the most powerful of engines but I was wondering what sort of mods can be done to it to give it a bit of extra power. It seems to run all right in the lighter corolla body, but I'd still like it quicker. An engine swap is out of the question at the moment due to lack of cash funds.
Also, what are the specs on the engine (power, torque etc.)?
