I want to do pi swap for my 98 mustang gt auto. What do I need I think ill get the intake manifold off am but what heads should I get and cams? I bought the fx3 tuner should be here soon... also should I get st headers or lt headrrs?
You could just get stock 99/04 heads with the stock cams and pick up a lot of power. There are write ups all over the internet. Try to get romeo heads if you can (01-04). If you want an aftermarket cam dont go bigger than a stage two. There are tons of choices for these as well. U do need the PI intake for sure. The american muscle one is good as it fits just like oem piece. Do not get the one from advance auto parts
Intake from AM is good. Heads would either need to be from a 99-04 mustang 2v or aftermarket heads designed for that motor. More than likely stock heads are all that you will need. Also if u can find used heads in you area you will need valve covers as well. There are two style of head used on 99-04 gts. Romeo and windsor. Romeo are better and have an 11 bolt valve cover. Windsors have 13 i believe. Try to get the romeos if possible. The romeo cam gears are bolted on also which is good because the windsors are pressed on so you cant degree them. In my area we have several places that specialize in rebuilding cyclinder heads and you can pick a set up for 300-600 depending on the head. Thats if you can find some on craigslist or a junk yard.
No the block stays the same. Windsor heads have 13 Bolt valve covers and romeo have 11. Also they stopped putting windsor heads on mustangs in 01 so find heads that are mid 01-04 with 11 bolt valve covers
i have a good experience with the shortys, a lot of people will say its not worth the money, but if your not going to be drag racing where every bit of hp and torque then go shorties, i noticed a great differnece with the BBK Tuned shorties, both sound and performance wise, nothing too drastic but enough to feel the difference.
