my buddy has a mr2 t, and damn is it fast. All hes got is intake and exhaust. Iv never drove or rode in a TTZ. But what i think you should do is go on to sum mr2 forums and ask them too. Sum guys that i have talked to with mr2s have said that they eat 300zxs for lunch, but thats just what iv heard never seen it. Check out [ www.bcmr2.com ] or [ www.mr2faq.com ] good luck
