Walbro Gss294 Will It Run Out Of Puff

[toy515]

hey guys

i have a walbro gss294 intank pump in my s15 with rb26 im looking at getting it tuned this week looking for 380 400rwhp but i dont really want to change pumps this week

sard 700cc injectors

power fc

hks gtss turbos

looking at running 18-20psi

my question is will the pump hold it back at all until i get my 023 in a couple of weeks

cheers

It held me back.

They dont like higher boost, which means higher rail pressures

I think the real question is, do you want to pay for another tune again after the 023 is installed. Increased rail pressure with the bosch will more than likely throw it all out again, esp running 700cc injectors.

just baby it around until you get the 023 installed and setup properly

why insist on trashing it and taking a big risk?

the walbro's are rated at their flow levels at 15v not 12v, so in your S15 or skyline they dont flow as much as they are rated for

I am using one in my Silvia and it's pushing low 280rwkw with no fuel issues at all, still using standard fuel reg and standard rail with 850cc injectors. Don't know how that compares to an RB26 though

it will probably die before it meets it potential

ive got a bucket of dead walbro's here......

[toy515]

what pump do you guys recommend 040 or 023?

044 intank is the best way to go up to 400 rwkws
