The xr4i pump is more than enough to feed a v6 cosworth.

Its a bosch 0 580 254 910 or similar pump delivering 130 l/h at 73.5 PSI.

Its good for 250 to 275 wheel hp. If you want a cheap replacement, take a look under a old Mercedes 280 and up, with k injection. They all use a 910 pump (or similar).

if you want more, get a 0 580 254 044 pump, that's 200 liter a hour at 73 PSI. That one is good for 450 to 500 wheel hp. Still not enough? Take a look at the 0 580 254 413 pump, that's 300 liter a hour at 73 PSI. However the 413 pump is very expensive.  Or use a dual setup with the 044, that's good for 900 wheel hp at 73 psi.

You do need a very good flowing fuel regulator with these pumps and it would a wise idea to upgrade the fuel lines to 8 mm id. or 10 mm id. with the 413 pump.

Ohh and 1 tip, watch out for imitation or fake bosch pumps. The same is even worse with walbro pumps as most pumps sold on ebay are fake china ones.
