Everyone knows a walbro 255 over runs a stock regulator but people still try. /ubbthreads/images/graemlins/dunno.gif The outlet orifice is only like an 1/8 inch id. so its just the nature of the design. I was posed a question today about a second gen car with this problem. My buddy had an evo regulator on hand and was going to try it out because all the mounting dims looked to be the same. Didn't call back to tell me if it worked or cured the problem but the evos don't have a problem with this so maybe he inadvertently found a new cheap upgrade. Said the lines were a little off but was doable. I'll post up what he says tomorrow.
