@ paul, the corolla has a different ecu map and injectors compared to the starlet. @expect, motions n/a also has a map, and a shitload more work done than a rolla mani to make that figure the corolla mani alone will not make 15bhp. my point that was just adding the rolla mani will see a 15bhp increase. i really wish i had the money to splash out on an aftermarket ecu with my old n/a as the only thing holding it back was the ECU i literally spent thousands on it chopping and changing parts, then i lost my job and went back to college, leaving me with no money to get a map and the few last little parts i had planned before mapping i then fell out of love with it after a string of incidents :/ but im deffo planning on getting another and finishing what i started with the old one. not wasting any time and money with body work like i did the last one though. at least until the engine is done back on topic though, i kinda like the g60 steelies and the different style your going to the usual
