What are the differences between the 7.3 Idi na ip and the 7.3 turbo ip? And has anyone heard of ifs pumps?

 

Pretty much the Turbo Ip's have a high fuel flow, can be achieved in 5 minutes with a n/a pump by turning up the fuel, that's why in the instructions for a turbo kit, it says to turn up the fuel 1 - 1 1/4 flats after the installation.

As far as ifs, I have heard of them, but I do not know anything about their fuel pumps, from what I've read, that are just about the same as ours

 

Don't know about IFS, but as dortiz said , I found out in my other thread, it's a direct fit, just different fueling setting.

 

i purchessed this pump from a going out of buissness injection shop for a good deal it is a ifs rebuild the guy told me it was for a na motor and as he was just a co owner of the buisness he didnt know if it would work it looks almost the same except for the screw guys are calling the torque skrew is not on this pump i think i will try and turn it up a flat and a quarter see how she runs i also picked up a sidwinder kit for 350.00 dollars any special things i need to do ?

 

The torque screws weren't on all years of the pumps

 

What does the torque screw do and where is that located? Is that the one with the lock nut coming out at like. 45°

 

It changes the fuel curve, sort of. You can adjust it to overfuel at low rpm then clean up at higher rpm with enough dicking around.

Long bunch of BS cut short if you get everything right (timing, main fuel screw, and torque screw) it can be adjusted to spool the turbo almost instantly and not smoke.

 

^ pretty much all there is to say about it

 

So, would do Mitch for NA engines?
I got another question, if I get my IP off without removing the timing gear and put a new pump on, in theory, the new pump should be timed to the same point as the old pump, right? Since it can only go on one way, with three bolts an the pin to time it, right? At least good enough to get it timed by a shop.

 

There is no reason to take off the filler cover to swap out injection pumps, Just remove injector lines, 2 wires on top of pump, 3 bolts that hold the pump to cover, and inlet fuel line from filter to pump
