For 350 rwhp the Supra TT nippondenso pump is a complete drop in. Also consider the competition fuel pump from www.rx7.com, as it's been proven to support a bit more than the standard nippondenso pump (7th picture down):

Never have been a fan of walbros, my (unsolicited) advice is to get rid of that little sucker for something like a Nippondenso pump.

Thanks! I've been pondering the idea of swapping out the walbro but i've had it for years running up to 18psi on twins and 850/1300 without a hitch. I'll try it with the KB and see how it works, if I see any indication that it's not up to the task I'll get something else.

There are two kinds of walbros 255s out there. original is reliable and quiet. I used one for four years at 375 whp never had an issue. Then there are the ebay knock offs which fail and kaboom the engine. They are very hard to tell apart as I have had both versions in hand at the same time. Bottom line is dont trust the chance of sourcing a bad one. G
