sr20 Redtop help xNEWx

[Silvia240 24'7]

ok I recently bought an sr20 redtop 240 and am just wondering what boost levels are safe on a walbro 255 fuel pump. Like what should I run for just daily driving and whats the max boost that it could run thanks.

the fuel pump doesnt really determine what is safe for the motor

anything above the factory set 7psi pretty much requires the pump otherwise your gonna run into leanness issues

as far as what it can handle....pretty much anytihng you throw at it the walbro will take care of

as far as more boost....your gonna need injectors fmic for anything above 10 (12 is pushing it) the stock t25 wont do you much past 13-14psi...after that its an all new ball game

oh and to make your life easier and to keep you from getting chared(i.e. flamed) use that big red flashing SEARCH button at the top of the page

hope that helps
