I have a MS4 and was wondering what size injectors I would need for a MS4 and 125 shot. Also should I buy a racetronix fuel pump set-up or a 255 Walbro.
This was also in the fueling and injection but not getting enough replys

Thanks for any help

I am not sure about the injector size, maybe someone else can give you a positive answer. My guess is that you will need 42# injectors and if I did my math right they should be good for about 650 crank hp. As for the fuel pump, the walbro pump is in the racetronix set-up but it has been changed to work with the stock fuel bucket. I am going to order this set up soon b/c I don't like the idea of drilling holes in the bucket and having the chance of burning up a stock walbro pump when I am under a 1/4 tank.

I agree... Lucas 42lb injectors and the Pacetronix pump and hot wire kit and you'll be fine

I have a racetronics and 32# injectors. I would absolutely get a pump and maybe injectors.

42's will be sufficent. Anything smaller and you'll run a risk of maxxing out the duty cycle.
