Phase 1.5 injector upgrade...
 

Hi all

I have a V4 sti engined wagon with esl, vf48 etc but still on 440cc yellows. what are my options for upgrading them to get full potential from the vf48 or better turbos?

Thanks

Rich

Has the fuel pump been upgraded? Seen some 550 injectors on ebay.

Sorry for the delay lol

Ive done the fuel pump, walbro 255. im looking at top feed conversions now, sti pinks seem pretty cheap compared to phase 2 side feeds of similar sizes.
