if all your gonna do is bolt-ons there's no need 2 worry about your mileage, if u plan on forced induction a rebuild is something 2 consider
I have a 2000 Mustang GT. It has about 146,000 miles on it and it has a manual transmission. I plan on upgrading quite a few performance things on it. And I just want to know if its even worth it. Heres a list.
1. JLT cold air intake
2. BBK throttle body
3. Steeda short shifter
4. Flowmaster 44 mufflers
I think of more stuff every day. But the reason I question this is because my car has quite a few miles on it. The car runs great just so you guys know. Would maybe an engine rebuild in the near future be reasonable to get all of these things? Also I will probably do a tranny rebuild as well. Professionally! I could never do that myself. Just give me yalls thoughts and opinions on this. Thanks
Subframes stiffen the chassis and really help transfer some power and stop body flex. A throttle body is pretty expensive and with only minor bolt ones you wont notice much if anything. Having a throttle body thats too big is a bad idea. I am not 100% sure since I dont own a 4.6 but I believe the stock throttle body is not a weakness and is usually good with n/a set-ups. The only people with the 4.6 throttle bodies that I have seen is with fi. Like I said get so subframes and ud pulleys and go from there.Thanks guys. 2 questions. What are sub-frame connectors and what do they do? And why not get both underdrive pullies and a throttle body? It will just add more horsepower right?
