Hi All,

I am fitting a 2.0 zetec turbo engine into my van which had a 1.9 cvh turbo engine with mfi. I will be using fiesta turbo ofab management, Can i use the standard fuel pump and filter or will it need to be replaced?. Power should be around 250bhp

Any help would be apriciated.

MFI pumps are generally more powerful than EFI pumps and MFI can be used on both. The accumulator shouldn't really be left in. It will cause trouble if your injectors leak even a little bit. The accumulator should bottom out at around 2bar pressure, so it won't really screw up the transient fuelling even though in theory the accumulator tries to maintain constant pressure and the EFI regulator tries to tune the pressure with MAP.

Thank you for the reply, I will leave the accumulator out then i think, Glad i hav'nt got to change the fuel pump, so should be nice and easy to sort out fuel pipes.
