fuel pump!???!?!?!
alrighty well this might sound like a dumb question but i dont know of any balt owners that have decided to and a fuel pump....i plan to do this after i get my stage 2 kit on...now is this a dumb idea for the balt or should i go with it because my best friend drives an evo 8 and his car is doing unbelievable on wit the 255 warlboro.....
last and here's the dumb part....some dumb **** not sure wether or not to believe im thinking not tho told me that it wont be the same size for the balt and that the balt wont be able to handle a 255 warlboro....
i think it will....any info or help would be great
ps....cams yes no?

ive always used walbro 255's in my dsm's. but those cars used a return style fuel system, wheres our cars use a returnless style system, so i dont think it would work.
but has anybody used a kenny bell boost a pump on these cars yet?
Does anybody know what the stock fuel pump flows and where it maxes out?

The stock fuel pump doesn't provide enough flow and pressure for the higher modified cars. I think the Walboro with a return line and a boost referenced regulator is the solution. We shouldn't need 60# (~660cc) injectors for what little power we are putting down.

It's also a matter of the differential pressure that goes through the injectors. For example, if there is 55 PSI in the fuel rail, but there is 20 PSI in your intake manifold (20 PSI boost pressure from a very small supercharger pulley), then the differential pressure through the injectors is only 35 PSI.

<ignorant post> you might want to look into the Solstice GXP fuel delivery system. Since it's direct inject they need high pressure pump. Don't know if it would be usable tho... </ignorant post>

someone said something about the bigger fuel pump only on somethin with more mods and i wasnt planning on doing the upgraded fuel pump until the stage 2 kit from new era performance was on including the stage 2 kit 50 shot and tuned/dyno'd... so thats when i was planning on it... is this still a bad idea

I plan on rasing my compression ratio to 9.5 to 1 and running some meth and 50 pound injectors on a ported and polished blower with the 2.79" pulley. would mine be fine?

In all honesty the 42's should handle it if they had the extra pressure to compensate for the added boost.

oh, so then how about 10 to 1? And for the injectors is there a slightly bigger set I could get for my meth setup? I will also be running the GM performance cams, ported and polished blower with the 2.79" pulley.... just double checking thanks for the major help.

They physically fit the 2.0L LSJ head, but the vacuum pump / cam sensor will not work in a stock engine.
