dpmfi - mpfi
 

k i want to change the gf's dpfi - mpfi what kind of difference should she expect ? fuel economy , performance wise and how hard is this whats involved and what is everything i need to do this ? searched the threads didn't see much help how much should the new intake cost and fuel rail and such ? does anyone have EVERYTHING I NEED for an auto tranny to do this ?

what car is it for?

you can get everything you need from an SI

as for performance wise...if its a d15...it isn't gonna help much...but it will let you get more out of the engine then dpfi will.

its a d15b block with a whatever head dpfi attached to it what all do i need new ecu ? and intake fuel rail and such ?

you need an intake manifold and i believe throttle body.... cause the intake manifold on there now will not have holes drilled for 4 injectors

she would notice better millage cause the gas mixed better and more performance cause more gas is able to make it into the engine

you need

SI distributor
injector resistor box
injectors
complete manifold
mpfi computer - pm6/pr4/pm7/pg7
and need to rewire a few things

I have PERSONALLY DONE these swaps flawlessly, I have all the parts, If you are willing I can wire and install/sell the parts to you for a good PRICE...

I have completed a multiport injection swap for :

dx - SIR crx
dx - ZC civic
cx - sohc ZC
DX - GSR crx
