I currently own a K plate Big turbo Esc cos, Im having problems engaging first gear. Can anybody advise me on a uprated box or gear set and at what cost. the car is currently producing 350-375 bhp so i need a box to take the power and more.

 

to be honest the standard box will handle that power, it sounds like the syncro is on its way out £500 should see a top notch rebuild.

 

try replacing the clutch cable first as it sounds like its stretched.
do u have a paddle clutch fitted as this can make it worse?

 

i have a quaife big tooth box for sale
