Motors.
Is the 1994-96 Ford Mustang V-6 exactly the same motor as a 1987-88 Thunderbird/Cougar motor? I'm unaware if there's very many differing intricacies..
If it is....what's the most inexpensive power adder outside of a cold air intake you can do to one of these motors? (inexpensive being...less than 300 dollars, let's say)
