If you are using a 50bhp kit and you buy one of:
NOS
ZEX
NX
etc

Be careful not to use it at low RPM or you will get det on the standard timing.



The only kit i would fit personally is a wizards of nos kit.


It delivers a smoother transmission between off gas and on gas, and this results in less isues with det.


Im not saying the other kits dont work at all, im just saying they arent the ideal choice for a 30%+ gain in power, and even less so for nearly doubling the power (like if you use it at 2500rpm to give 50bhp extra)
