Do I NEED TO CONVERT OR STICK WITH SPEED DENSITY?

[1jmc2003]

I have an 88 5.0 gt. I am wondering if i should do the mass
air conversion or not. I plan on keeping the car pretty much stock except for the following mods.
Equal length headers.
373 gears
Off road h pipe/ flowmaster exhaust.
BBK cold air intake.
140 amp alt
a/c delete

I do not plan on any other mods. Would I be better off sticking with the speed density? Or will I run into some
problems like the idle for instance.

Also can i put a 1992 gauge cluster in an 88.
Will the check engine light still work?
I noticed there is one on the actual cluster.
which one will be hooked up?

With what you've got, stay SD. I've done that much without any problems..

The cluster I'm not sure..somebody will chime in tho...

im close to the same with mods on my speed density and the idle isnt that bad.
im in the same situation but im gonna save the money and now buy some 3.73's
good luck

I put a 1993 cluster in my 1989... pretty much every single wire moves around, only like 3 stay in the same spots...

use this for reference:

I would stay with your SD system. I have with about what U want and it works fine. I will have 1.7 RR and a Cobra intake real soon. Hope that wont change have nice my SD system runs!!

Does the speed density stop showing up after 88? is it MAF on the 89+ i have no clue about the difference between them

 

[87gtconv]

Yes, 88 Calif cars and 89+ for rest of country have MAF!

Your car should run just fine with those mods, mine does you can see what I have in my sig.

California cars had mass-air in 1988 while all others were SD, all mustangs starting in 1989 were mass-air.

thanks eric and did your 1.72 RR fit under the stock valve covers too?

 

[eric88gt]

Yeah, I just had to remove the oil baffle below where the filler cap is, and grind a little bit off of where the baffle was mounted.

Would a change in injector size bring a need to switch from SD.

if your looking for MAF parts, I have 91 stock stuff. TB/EGR, MAF etc.

If you are going to change your injector size than you do need to switch to mass air unless you want to use a custom chip. If you are going that far than go mass air anyway, then you are ready for bigger mods. Ford sells the harness adaptor, its about 90$ cdn it's just hard to find a computer for the thing (it was for me). The harness isn't hard to install, just take your time with it. good luck

The cost factor is what gets me on this one. I stopped in Ramcharges and was told that by the time I was done doing a mass air conversion I would be out of close to six hundred if I bought one of their kits. That's alot of cash for no additional HP. To get a chip burned and installed would cost half that. If you are telling me I can go to a larger injector size and only have to have a to purchase a chip, that seems like a good move to me.

I appreciate your response.
