there for a 1994 lt1 and im not sure if there is really any diff, will any of them work????? looking to know asap, plan on putting my order in befor monday

thanks

p.s for the racetronixs fuel pump. i just need tog et the pump correct? i dont need the plug and play wireing harness to make it work do i? its just an upgraded power source and better ground right?

 

come on pples. i know some one knows

 

Of the above choices, I would choose the flow matched set.

 

No, to answer your question, you do not have to have the hot wire kit, but you pretty much SHOULD get it. The factory pump wiring sucks ***, and when you install an amp hungry pump and try to run it off the already lame factory harness you are just asking for trouble. Get the hotwire kit, it is good insurance for sure, and it is very well made.

as far as injectors, I second the flow matched ones.

 

but one one of those injecots will work? fit with the factory lt1 rails and intake/ wireing harnes?

so the $60 thing is the hot wire kit??
the pump itslelf is plug and play?

 

any one???

 

Any of the injectors you list above will work on your car. You will have to retune the PCM for the larger injectors to function correctly.

 

that will be getting done, is there any large...*hp/trq* benafit to go with flow matched?

 

A little, but mainly for reliability. Flow matched injectors ensure you are getting the same fueling to all cylinders.

 

ok and one last question

FLT1-FPA is the fuel pump that is everthing in the pic below, correct?


and

FLT1-FPWH Plug & Play Wiring Harness is the hot wire kit below, with out the body ground, correct?

 

ok well i got there disc 42's that are flow matched

and there fuel kit *pump, wire kit, body ground up grade and BAP thingy, it only coust 8 bucks more then jsut getting the pump and wire kit* soo well see how it all goes....hope it all works right
