mechanical side, im not worried bout, engine mounts will be all custom,ill be using 4 mounting point not the usual 3, if i use the stock mounting point then the engine sump sits too low the gound, so ill be raising the engine, cv's will be using the corolla sportivo ones,will be mixing and matching with the starlet and mr2, brake master cyclinder has to be shortened as the head hits it, so the solution is, using the mr2 spyder one as its short by about 1", exhaust will be custom as for wiring i dont wanna use the starlet cluster, so its either corolla or celica, im leaning towards the celica cluster, but as the ecu is in the engine bay, cant i just use the celica dash harness and corolla engine harness from what i understand the corolla has abs, and the celica doesnt have it in there base model sx, but does in the zr. its easier to get the sportivo harness than getting a zr harness. cheers
