I just bought a 2001 Ford Excursion with a 7.3L that is bone stock. It has around 200k miles on it, and I'm looking to do some upgrades. I will use the truck for daily driving, vacation trips (6-8 hour highway), and very limited towing (towing a car on a trailer 2-3x a year). The main goals are more seat of the pants power, better gas mileage (20-25mpg range on highway), and reliability. I won't use it for racing, hauling big loads, showing off, etc. I also want to be as frugal as possible with $$, so only changing or upgrading what NEEDS to be done. Also, I don't want to change to a heavily built transmission at this point.
I am planning on a 6 position chip, turbo upgrade and 4" or 5" exhaust system. Injectors: only if necessary.
With all that said, I've seen a lot of posts on the GDS turbo and the Garrett GTP38R. Both seem to be the same price range, so is the GTP38R a better choice (and if so, why)?
What injectors? Stock? Or do I have to upgrade to Stage 1 or Stage 2? I've seen some stage 1's on BDP, but not sure if I need them or not to get where I want to be.
Exhaust: I've seen a lot of people running the MBRP 4" system. For what I'm looking to achieve, I assume that a 4" would be best. Pro's / Con's?
I'm looking for people that have similar goals as mine with similar combinations as the above, so I can get real feedback from people that have tried those combos. Guys that build their trucks for racing or pulling have a different set of requirements, and probably deeper wallets than I do
