I've currently got a toyota starlet gt ep 82. I've currently got stainless steel exhaust and manifold system, competition race clutch, grooved rear discs, fount mount inter cooler, chrome hard pipes, sard adjustable fuel pressure regulator, lowering springs and shocks and an air filter. My next idea is a td04 turbo and uprated injectors, I've been told I'll probably need a fcd. Would I need a re map straight away I could I put it off for a while ? Or is there something better I could get for same price ??
