Though I'd post some of the most common questions I'm asked and a couple tricks I've learned over the years...I'll add more as I remeber them. We can also make this a big FAQ and include all the brake upgrade stuff too...
HO Conversion, You need:
E7 Heads (Found on 87-93 Mustangs, 89-92 Lincoln Mark 7's and 87-96 E/F series w/302 (351w has larger head bolts)
HO ECM, engine computer (Mark 7 to keep cruise on the 88-91 boxes, 86-88 mustang for the 86-87 box)
19Lb injectors 86-up mustang, 89-92 mark 7, 87-96 E/F series trucks (302/351)... They have an orange top.
HO upper intake 87-93 Mustang, 89-92 Mark 7
HO Throttle body
HO cam 86-93 Mustang, 89-92 Mark 7
The 2 modifcations needed:
The linkage arms on the throttle bodies need to be swapped. It's easy and straightforward. Grind, swap reattach with screw, JB weld, or actually weld it. The EGR spacer will need to be enlarged to 63mm. A couple minutes on a lathe fixes it up. The 93-95 Ford lightning and some Aussie Fords use a similar EGR spacer if you can find it.
Common misconceptions:
1. Wiring. There are NO changes to the wiring for the HO conversion.
2. Wiring . There are NO changes to the wiring!
To help you get the most out of the HO conversion:
Dual Exhaust. 2.25" minimum.
Headers. Mustang shorties work with some modification, most people get the H-pipe too and get a cat back exhaust done.
Trans: Mustang/Mark 7 Governor. Raises the shift points to match the engines power band.
Fuel pressure, some can get away with the stock pump. But not all. Check your fuel pressure and make sure it's good at WOT.
Other tips/Tricks
1. Timing is everything! Make sure your timing is correct. If it's off, it'll kill your power and milage. Bump it to 12-14* for a little extra HP, just pay attention to detonation, if it happens, back the timing off.
2. Speedo swap. Very common thing, every one wants a 140 PI speedo, but what about the milage? The odometer comes apart pretty easily. pop the pin out and set the milage. To help keep the numbers aligned while you reassemble, put some tape across the opposite side of the numbers to hold them in place.
Mike's 16 second lopo recipe:
Pretty simple recipe. HO upper, TB, and bored lopo EGR spacer. Mustang headers, 2.5" header back exhaust, 3.73's, 2200 Stall lockup converter, rebuilt AOD w/ shiftkit, smog pump removal, electric fan, removal of WP driven fan, 110lph fuel pump, and a custom cold air intake. Lots of timing too. I tuned it by ear and timeslips. I also ran 26" tall tires instead of the 27" tall stock tires, which helps for gearing. My trunk was bare. I never ran with more than half a tank of gas. Iced the intake between runs. The car should have been much quicker, but the frame was horribly bent and ruined the launches. The best the car ever got, even with the HO was 2.18.
And since all the supporting stuff was already done, when I did the heads and cam, I dropped from the 16.03 to a 15.54! The car was far from pretty, but it worked great.
Misc Info:
TB sizes.
Lopo = 55mm
HO= 60mm
Explorer =65mm
