I know there is ample info on here for the S.D. to Mass Air swap, but I woudl rather cut to the chase than sift through hours of other postings.....I have an 88 LX 5.0, currently I am running the stock S.D. system but I will be changing to the Mass Air. I have upgraded to 24#ers, and have a 75 mm throttle body ready to put on, the car runs great currently, other than running extremely rich, which it did before the 24 # injectors, the previous owner installed a FRPP B303 cam, along with other upgrades, the extent of which I do not know. Short of tearing the engine down, I won't be able to find out since he has moved to another state. I do know that what I have read, the Mass Air will work wonderfully for my situation as it will allow whatever upgrades to work to their full potential. What I want to know is what size mass air meter will work best for my situation. Also, the car was originally an auto, but the previous owner converted it to a WC T5 car, of course the cruise control will not work now. When I purchased the car, the computer was fried due to faulty wiring hack job by previous owner, I replaced the computer with one for a five speed. Which should I get now, the manual computer or the automatic computer, and will the automatic allow my cruise control to function again? Thanks for the help. I will post what I end up doing with the car.
