I like the N1 i nearly swapped my mugen for one. But as im tracking it i didnt fancy popping the bung in and losing most of the noise so ive stuck with the mugen.
Just thinking, my mates civic with the integra engine in it, is bored of it now. If your interested i could ask him if he would sell it. Its in VERY good condition, he did a interior dash swap and engine swap himself and has NO wires showing in the engine bay. Has Mitsubishi evo recaro's in it amd it made 197bhp on the rollers with the standard map. Uprated brakes and suspension too with white Braid wheels... just a thought.
