What size injectors and fuel pump for MS4 and 125 shot

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.

Thanks for any help

I would go with the Racetronix fuel pump and 60lb injectors, which will be more than enough injector, and are very tuneable. http://www.exoticperformanceplus.com....html?item=583 Bob

Who knows.... you didn't bother to post whether that was a wet or dry hit.

Exactly! If it is a wet shot the pump will supply the needed fuel to the fuel solenoid. If it is a wet kit you can use 30# injectors and a Walbro 255. 42# or 60# injectors will leave you room to grow though.
