Need Mass Air Help
I have an 87 LX t-tops with from what im told rare grey interior. Its speed density and I want to change it over to mass air. Without buying a 600$ kit what parts would I need from a donor car to complete the upgrade? Do I have to install the FULL wiring harness from the donor car?

i would goto a junk yard and find a donor car and get the whole kit for $100 and yes you need the full harness to make it work.

Is there a specific Computer I need? The car has a metric AOD, the car was originally a 5spd, it still has the clutch pedal and everything. Should I get a auto computer or manual computer?
I need:
Computer
Harness
Mass air meter w/bracket
Cold air pipe
what else?

https://www.tamparacing.com/forums/s...hreadid=146119 for a few ways of doing it.....
but the general jist....
*You need an A9P or A9L EEC $100-150
*The mass air meter, might as well go aftermarket and get a c&l or pro-m used for like $100-$150
*bracket can probably get for free or dirt cheap
*conversion harness from any vendor that makes em $40-$80
I believe mass-air.com sells the $40 conversion harness.
Computers dont really matter, they have no control over the tranny its still mechanical. But the A9L is the 5 speed computer the A9P is the auto comptuter, not much differenence in them as far as I know other than the timing tables. But most ppl go for the A9L.
Why are you going to mass air though? There is no need unless you are gonna start doing some motor work like heads etc.... basic bolt ons really wont affect it.

What are you going to do to the car that you need to convert to mass air? Unless you're going to be installing a bigger cam, intake and heads there is absolutely no need for it as there is no power to be gained from just a swap alone.
For a 1987 5.0 an entire engine harness from a 1988 California 5.0 or an '89 5.0 is a direct swap being that those years have the MAF sensor harness integrated into them while retaining all the same exact connectors and wire colors for those years (1987-1989; possibly '86, too). Used computers at $100 or more are a ripoff. Remanufactured EEC cost the same and work just as well if not better. I rewired my '88 for mass air back in December of '98 using a Standard™ part # EM073 (A9L or A9P designation unecessary) for $104 with a junk EEC I used as a core exchange at the parts store. Go to the junkyard nearest you and cut out a
MAF sensor harness from a late 80s-early 90s Aerostar, Tempo, Escort, etc and cut out the harness connecting to the EEC along with some length of wiring. Remove pins from junk EEC connector and solder the wires going to the donor MAF harness. I have to look up again in my old paperwork which # pins have to be moved and added. I don't think I spent more than $150 on my swap. It takes patience and time. I scavenged a MAF sensor from an early '90s 5.0 Thunderbird. Works great, although now I'm at a stage where I need to upgrade it.

Thanks guys for your help, yes I plan on doing major upgrades. So what ARE the can's and can'ts of speed density. What can you install and what can't you?
