You'd be better off asking in the 2nd Gen section for that answer.

Oddly enough, the SE pump puts out more volume than any of the later FI pumps Mazda used in thier rotarys. Even more than the standard Walbro 255 lph upgrade most TII owners opt for.

Most snd gen guys love our SE's for the fact of the bigger injectors and our fuel pump. Not sure why they went smaller in the next generation. Sean, what are you running in your T2 conversion?

I did the in-tank fuel pick up mod (slosh baffle and pump mounting ring from FC welded to a FB tank) and running a FD pump inside. I am looking for a twin turbo Supra pump though, they flow more than the FD pumps do....
Good point about the injectors, just too bad they are only compatible up to 87.5 FC's, anything later has the high impedence.... Sucks for me, all my stuff is S5

I don't know, can you. Since you haven't said why you asked the pump question , nor said what your plans are, I can't answer that question. The SE pump is the only external FI pump on a rotary, all the later ones are internal and require tank mods along with parts from a 2nd gen fuel tank. If that's the route you wish to go, I can do the tanks mods.

I'm using the SE pump. But the car is not finished yet. I'll let you know if it works. According to everyones data about the stock pumps the SE one is the easiest to use on a FB. Not to mention you could easily change to a aftermarket external later since you have the place to mount it. If you out grow the stock SE pump.

SE pump will work fine, just don't let the tank get under 1/4 during high boost and cornering.
