TD04 great for top end but taking your 16 year old plus engine over 135mph is pretty risky! Planning on going forged td04 or the blitz k24 etc definately worth it, I always wanted to see a 5e with a CT12 combo you hear in Japan all the time they downgrade their big ass turbo's for smaller one's cause of the torque, yes you can have 400 hp but how fast can you get to it lol
