Re: 1989 gt

damn a STOCK , Unmolested 5.0 ? don't see them to often ...
advance the timing to "14
remove the airbox muffler , its in the fender well connected to your air box
and get a K&N replacement filter , or just trash the whole airbox and put a CAI in
exhaust , and gears and if you have the $$ and intake manifold does wonders too , along with a set of 1.7 Cobra roller rockers ...
those are the first and cheapest things you can do

It will be fine with the stock ECU.
I have a boatload more mods than that and I'm still running the stock ECU with no tune or chip.
Like dreamstang said when you get farther into it, a chip or tune could help you pick up some additional horsepower, but for now you will be ok.

Any mods that increase the air flow much on a speed density car will cause problems.
Your first mod should be to convert it to MAF.

Not really a fan of those.
Usually they cause charging problems and require the installation of a larger alternator on the 79-93 models.

You're an exception or maybe someone previously changed out the alternator for a larger one?
They usually cause problems with discharging when the engine is idling.

Re: 1989 gt

STOP!

There was a misunderstanding about one of my responses that started this whole discussion on what year Mustangs had MAF.
The person I responded to has a 1987 which is speed density.
Refer back to where the MAF discussion started to see the response.

Meansaleen is correct with his answer.

Haha my fault guys I started this lol. Yes my car its an 87 with speed density and I have headers x pipe flowmaster 10 and a gt40 upper and lower intake. I have not switched to maf yet because my funds ran out for the time being. So my question originally was if the guy who was doing similar mods as mine if it would all work on the original CPU which his would because be has maf but my question is which of these mods of mine would be ok to use with speed density until I could convert to maf?

I was not a member of this forum when I bought my car or maf would have been the first mod.

Also what's a good spark plug to use?

---------- Post added at 05:36 PM ---------- Previous post was at 05:35 PM ----------

O none of these have been installed yet only the cai has

I wouldn't install to much until you have been able to convert it to MAF.
That way if you have any issues they might be easier to diagnose and repair.
You could low buck the MAF conversion by maybe finding a wrecked car or one that someone is changing to carb.


I believe the Autolite 25 plug will work for your car.
You can mod them a bit if you wish, but it will reduce the life of the plugs.
Take a look in the Useful Mustang Info thread for plug mods.

I haven't installed long tubes yet.but you definitely don't have to pull motor.and never heard of anyone pulling the starter either.but the dominatrix is more accurate.

I would suggest buying header bolts though.they have a smaller head than normal , so it helps getting a wrench or socket on them.because you will have less room by the bolts since the new headers have larger than stock pipes.
