looking to go for the MD321T twinscroll on a 2006 jdm hawk, ive been told that the TMIC is good for 430bhp is that questionable ? also the standard airbox is good upto 450bhp again ? what fuelling/injectors would people recommend there's already a walbro 255 fuel pump installed looking for advice from those who have done these upgrades.

 

Look at my project thread.

 

Thanks very much
