ok i have a 90 gt. AOD so far i have mac cold air, 75mm mass air, superchip, bbk headers, bassani offroad x pipe, and flowmaster two chambers... What do you think my next step should be... without spendin any more than $300. I was thinkin maybe some underdrive pulleys or a new throttle body
Since the budget is so limited, you won't be able to do gears with that - unless you install them yourself. AODs need a good shift kit and a higher stall converter to match the gears to REALLY wake an auto up, but you don't have that kind of money.
Pulleys are a proven mod. If your not going to change out heads for a while you can get your lower intake ported for ~$150 including shipping both ways. The Explorer can be found sometimes for $150-200 also. It will give up some lower end torque to a well ported stock lower - not what you need right now with a stock AOD and no gears and why I would suggest a ported lower first.
A new TB won't give you much if any power with the combo you have - wait until you add heads/intake upgrades.
Typhoon intake and 75mm TB. Thats what I did at about the same level of mods as you got now, although you will lose a wee-bit of off idle response and torque. Comes on hard over 2500 RPMs! Might be too much for an auto trans without a higher stall converter so go with a Cobra/GT-40/Performer/TFS street etc...
I already have a set a of 3:55's, ive been told to go at least 3:73 but i dont wanna destroy my gas mileage. So do u think the wisest step of anything is gettin the gears installed? Or porting my intake... Ive also heard that the Typhoon intakes fit like ****.
