In the new year I want to take the plunge and do some power mods. Ive decided on a explorer setup (upper and lower intake with gt40p heads, stock HO cam maybe with some 1.7s) Ive done my research, but theres a few things I still have to pick your guys' brains about. Thanks in advance for the help, i know there are alot of questions :
1. I've done some research on the EGR, and Ive decided that it would be in my best interest to keep it (lower combustion temps, gotta pass emissions, better fuel economy, lower risk of pinging) I understand some explorer motors have an "internal egr" and apparently the fox 5.0s do too. What is this? Can an internal egr be run in our 94-95s? If so, that would save the engine bay clutter, which would be cool. What years of explorer 5.0s would have heads and intakes compatible with our stangs?
2. If I got a performance catted H pipe, would these cats need the AIR pump? I think it was just ford's stock cats that needed the pump, but I just want to confirm that so I dont delete the pump and then foul my new cats shortly after (As much as I want an OR-H, i have to pass emissions.. although I might decide to just get an OR and then swap the stocker in for the sniffer test) I would like to delete the AIR system if possible.
3. If I retain the stock HO cam, should I use 1.7 roller rockers? Also, would I benefit from degreeing the cam?
4. Grady posted a chart awhile back with some dyno numbers of combos using gt40ps, explorer intakes, and stock HO cams. Could someone tell me where to find this? Also, what kind of power can I expect from this combo (I recall seeing some numbers that looked quite good.. again my combo will be CAI and K&N, explorer upper and lower, gt40p heads, stock HO cam with 1.7s, P specific shorties, high flow H, flowmaster catback, tune)
5. I drive the majority of the time in town, but I dont want my highway mpg to go down the drain.. what would be a good set of gears to compromise between pep and mpg? (im thinking 3.55)
6. Any idea if gas mileage will decrease/increase/remain the same? I heard rumours that because the gt40ps are optimized for a clean burn, efficiency actually goes up.. is this true?
7. With the exception of valve springs, can I just bolt on gt40ps to my 5.0? can I use stock pushrods?
8. Does anyone know a good tuner in the Vancouver, Canada area?
9. Im tempted to just put nitrous on the car and call it a day, but I know ill be happier with this combo (and it will be safer). Please talk me out of the nitrous
