speed d to mass air?

[Graydon5oh]

ok i have a 87 gt and maybe getting a motor that is out of a 93 meaning it would be mass air i plan on swopping because of the fact the motor has very low millage cobra uper and lower intake cold air electric fan after market heads headers and ignition that are known to me... so what do i need and need to do to swap my car from speed density to mass air

you also need the computer outa that 93 (or anyone that suports mass air)and a wire harness summit sells then for cheap.

well ill have the whole car or whats left of it it was a hatch back lx 5.0 it was hit by bus then spun around into a light pole

 

[88stangmangt]

well there you go it is located on the pass side kick panel just swap em and get a harness and you are set.

iv got to pull dash and everything to replace the harness dont i?

 

[88stangmangt]

no, i wouldnt i would run it through the firewall.

 

[88stangmangt]

but in order to get to the gromet all the computer wires go through you will have to drop the heater box. Not hard 4bolts or so and it drops.

ok cause after chagnign the heater coil i didnt want to ever have to do that again

You don't have to drop the heater box. It's a pain, but you can get your arm up to the grommet. Poke a hole in the gromet with a knife or coat hanger and run the wires inside from the engine bay, then reach up and pull them down.
