i was wondering if it was possible to run a R32/R33 Stock fuel pump on our classic sti.

I have read somewhere that the stocks sti pump is rated at 145/L while the GTR is rated at some site at 190/L and 252/L.

Would these pump be adequate to run 550cc injectors along with GT2835??

what power level is expected on these mods assuming all stock internals?
car is already fitted with the usual intake/exhaust/power fc/ n front mount

 

get a walbro 255lph for 80 quid mate just to be on the safe side .

 

No idea but why not just fit the uprated Walbro pump? Its 255 LPH

 

Beat me to it

 

lol fast key tapper , great mind's think alike ah .

 

reason y i am contemplating getting a gtr pump is due to counterfeit walbro pump being sold in the market. even sard regulator has counterfeit or imitation product coming from china. just wanna be safe rather than blowing up the motor

 

buy it from a decent place i.e , harvey ,api etc etc and not of ebay from china and you shoud be fine .i paid £60.00 fom a member on here.

 

Scoobyworld have them at £85 at the moment.

 

guys do you have any ideas how much power this setup would give?

do you think i could just stick with the standard hks actuator that comes with the kit or do you suggest i connect the boost controller ?

 

anyone try using this sti pump upgraded rated at 180L/H with anti surge? would these be helpfull? i have these on hand also

been reading this and i think the 180L/H fuel is more than enough to provide fuel for 350-400hp
