You sure you got in the right car?
TTRS is a 5 cylinder and doest sound too bad IMO:
I know that one is modified but I bet its not much more than a chip and an exhaust, Ive read you can get 430hp from just that. Frankly I dont think its comparable even to the 370ZN (TTS is) and Im still laughing a day after reading that people are actually comparing 1M's and Cayman R's to 370Z's, Ive caned all three and trust me, ze Germans are considerably better (and more expensive funnily enough)
A little note to Zed owners...
