good shot for an NA?

im buying a zex system for my sl 5 spd. it comes with 2 injectors, 75 and a 100....OBVIOUSLY i would like the 100 shot but is that safe for a typical sl?? im gonna invest in a wi-band air fuel ration meter to be safe. any opinions?? and whatst he horsepower gain for say a 100 shot?

i kno a 75 shot is fine if everything runs well... yeah get the wideband and moniter knock... i bet it'll be fine... and if it is, maybe, however i doubt it, you could go higher

You can easily go to a 100 shot, as long as you upgrade your fuel system bigger pump, perhaps better flowing injectors, correct dyno tune, make sure the motor is in good condition no oil leaks, full maintanence, oil changes, colder spark plugs, you should be good to go from there 75-100 shot you will be fine.

We run pig rich as it is. There is no need for bigger injectors on a 100 shot.

but a bigger fuel pump orlly wouldnt hurt?

A 255lph may not be a bad idea.

255 is overkill. Stock tt would be fine

overkill is the name of the game

Yeah but when I put mine in i upgraded my pump to a 255lph, its always smart to have a really nice flowing pump for a 100 shot.

255's overrun the NA FPR. Thats bad news. 190lph (stock TT) is PLENTY on a 100 shot even.
