Im putting a cam and gt40p heads in my 1996 f150 was wondering what Junkyard performance parts (mustang/lightning/explorer) i could upgrade my truck with. Plan on a typhoon p plus intake single port TB but what Throttle body and MAF meter could i possibly use that will fit properly that i could pull off a stock junkyard vehicle. Plan on buying moates quarterhore/binary editor to tune all fuel and air perimeters also.

 

How big of a cam are you thinking on going with ?

 

Either comp 35-320-8 or Ford e303

 

What's on the truck now.. stock MAF is 70mm or something isn't it? The Typhoon intake will take a 70mm TB max without breaking out the grinder and if you do that you have to disable EGR.

 

It has the stock twin 50s for the 5.8. I found a plug in sensor that tells the computer the egr is closed, im going to do that then remove the egr. Which junkyard TB is 65-70mm and will work with single tb typhoon on my truck? Is a larger MAF meter required or could i use the one i already have?

 

What about the MAF meter?

Don't do that, unless you get a tuner the EGR system on this motor cannot be eliminated.

The stock meter is fine for a stock or mildly upgraded motor.

 

You can get an explorer tb that's 65, I think that's the biggest oem tb that will bolt in place.
You can use a mustang egr/tb spacer and the original egr valve will bolt to it. Hook up the wiring and vacuum, just block off the valve itself. That way it won't throw a code and the check engine light won't come on. The egr eliminator plug is over rated. I've had it throw a code on my mustang a few times.
The 19lb injectors and stock maf is fine for as much hp as that cam and heads will produce (without a custom tune) If you decide you want a custom tune, then I'd get 24lb injectors and get a mark8 80mm maf and build a big airbox with filter (it won't bolt to stock airbox top)

 

I planned on getting a moates quarterhorse tuner with binary editor(If i really have to id like to stay on budget) but if i could slide by without it thatd be great. I had thought though that i would need to tune it for Typhoon single TB inlet and 65mm TB from explorer since its more air flow? Also i seen where some guys had entered there upgrades and it estimated there hp/tq, if i listed what im going to upgrade my motor with could one of you calculate it?

 

Ok im getting into the egr block off plate this weekend. All i have to do is block the valve from the throttle body and leave all solenoids plugged in and it wont throw a code?

 

why not stay with the S/D and use a vacuum amplifier to smooth out the vacuum pulses for a smoother idle, that would be a WHOLE bunch more cost effective, don't you think.

 

He's got Mass-Air on that 96

 

ah, then he doesn't need to replace it with a larger unit, the manifold is more restrictive than the MAF meter..

 

Conanski offers good advice on the EGR, the harness plug from RJM may or may not work the way it was intended, some people disable the EGR by sandwiching a thin sheet of metal between the EGR valve and the manifold, i did it a little differently and simply removed the pipe that runs from the passenger side exhaust manifold up to the bottom of the EGr valve then installed a plug on the manifold and another plug on the bottom of the EGR, the harness is still connected and i get no CEL and there are no exhaust gases flowing onto the intake manifold and the source of heat from exhaust gases to the intake manifold has been eliminated..

 

The ONLY way EGR can be eliminated on the OBD2 mass air system is with a tuner, you can't use the RJM plug or block off the valve at the intake because the DPFE sensor is always looking for exhaust flow in the EGR tube, so all of these tricks will generate codes and set the check engine light.

The stock twin 52mm throttlebodys on the 5.0/5.8 motors are equavilent to a 70mm single throttlebody, and both of these will support 350hp no problem so neither is a restriction on this motor now or after it gets upgraded heads and intake.

 

correct, OBDI has no DPFE sensor and is more easily modded.,.
