I bought the Official Mustnag 5.0 Technical Reference and Performance Handbook and I have to say that it is a must have for any 5.0 owner. Now my question is though I have a 1990 mustang gt 5.0 stock other then o/r h-pipe and 2 chamber mufflers. I want to know the next mod i should buy for my car.. Please help.

Go for the free/cheap ones first. Bump your timing up, rip out your air intake silencer and put a k&n panel in the filter box, headers, MAF, TB, gears, etc.
 
On a budget? do the junkyard upgrade...

Gears - 87-88 T-Bird Turbo Coupe rear axle - disc brakes and 3.55 or 3.73 gears in one package for $125-$300. Add another $100-$200 or so to complete the brake upgrade.

94-95 Mustang GT MAF - $40-$100. It is 70 MM instead of the stock 55 MM on regular stangs built prior to 94. It uses a slip on duct on the side that goes to the throttle body and a 4 bolt flange on the other. You need a $25-$35 flange adapter from Pro-M to fit the stock slip on air ducting that goes to the air box. Wiring plugs right in with no changes. *1

95-97 Ford Explorer intake manifold & throttle body $150-$300. The intake manifold flows 220 CFM +, much better than stock. Throttle body is 65 MM, bigger than the 60 MM on stock stangs. I got a 96 with EGR passages that match the stock setup, so my smog gear works just like factory. You’ll need a 65 MM EGR spacer & new gaskets for $65-$90 so you have a place to mount the EGR & throttle linkage.

3G alternator from 94-95 Mustangs or other Ford. $20-$120. A must have to make the electrical system work like it should. You’ll need a 4 gauge power wire and a 125-135 amp fuse to go with it about $15- $30.

Lincoln MK VIII electric fan -$40-$160. Free up some HP by not having to drive the stock fan. The 3G alternator upgrade is a must have prerequisite before you do the MK VIII fan. You won’t have enough electrical power if you don’t do the 3G upgrade.


*1.) I got a metal flange adapter from Powered by Ford for $35 and tax. That was over a year ago. Summit Racing may also have one too.

thorttle body, i would go with an accufab. billet alum and so far i never have heard of any problems with them.

mass air meter, C&L or the Pro-m is about your only choice besides the lightning meter. they each have pros and cons. it is something that you will also have to read up on so that you can make an educated decision for one.

Gears, pulleys and MAF (Pro-M). Of course a timing bump.

I'm really new at all this like im only 18 years old and i just bought my first stang last june. I dont know what you mean by timing bump and do you mean rear end gears when you say gears? and alos is there a difference btwn maf and maf sensor.

Yes, rear end gears. maf is an abbreviation for mass air flow. Technically, it's a mass airflow sensor, but it's commonly referred to as maf.
