I have a ST205 Celica, no power mods other than basic intake and exhaust work, will buying a walbro 255lph pump cause me to run rich?
or will I see any improvements in any rpm range? -------------------- 1994 Toyota Celica GT-Four ST205 Turbo 4WD, Black

Intank pump upgrade wont do anything different unless your factory one is worn out or broken. I don't know how many LPH the ST205 factory pump is but it's obviously fit to feed the factory 540cc injectors at standard pressures. Only reason to upgrade intank is if you plan to upgrade your injectors or your factory pump is worn out and want a cool buzzing noise every time the cars running.
Surge tank + external however will give you benefits of preventing fuel starvation during hard cornering and give you a base to upgrade your injectors should you choose to do so in the future. -------------------- Mike W
