[QUOTE="blksn8k, post: 1029297, member: 64142"] I assume the Walbro fuel pump that comes with the GT450 kit replaces the in-tank pump on a Mustang. Will that pump work in the Sport Trac's tank? If not, can they recommend a pump that will or is there another alternative? Also sounds like no matter what pump you use you should probably upgrade the wiring to the pump to handle the required voltage. What about the exhaust system? They seem to suggest that it's not necessary to switch to tubular headers on a street driven Mustang. Also not much gain with shorties. Can the same be said for the Explorer and ST exhaust manifolds? They state that a restrictive exhaust will raise the boost level. Have you asked what boost can be expected using the GT450 kit with the factory Explorer exhaust manifolds? Will the stock pistons and rods handle that amount of boost? Can you run this combo safely on 91 octane gas with the stock manifolds? [/QUOTE]
