WOW this has been going on for awhile! Well Heres my 2 cents
1997 Mustang GT
Has a 2001 Lincoln Town car P.I. motor swap
K&N c.a.i Small SOTP feel more engine noise
BBK 78mm throttle inlet (Highly recommended!!) car pulls so hard from 4500 up
1/4 " Dallas mustang plenum spacer. had to drill this piece on the two front bolt holes, they didn't line up well. Installed with the BBK throttle inlet no EGR issues
Polished Pro-comp intake ordered this off ebay for $400 new. When I got it it turned out to be a re boxed new professional products. I had to modify it to accept my coolant sensor (96-98 have two sensors 99-04 only have one) noticed a little more bottom end 3500ish to 4500ish not much on the top end. Not really what I expected. But. I would do it again.
Pypes stainless long tube headers (highly recommended) I was surprised by how well they fit given the low price. But, I did have to dimple one of the primaries to clear the starter solenoid. I did these whiles putting the new motor in. If you put them in with the motor in the car good luck
BBK o/r h pipe it fit the Pypes headers just fine, but I had to have new hangers welded in. I'm guessing the BBK headers are a little shorter. hangers were about an inch off, no biggie
OLD school Flow master 40 series mufflers that have been dumped. these things are at least 15 years old, they came off a friends car. They are well broke in... AND they sound soooo good. They do have a bad drone at highway speed but It doesn't bother me. They are loud and aggressive and always get a look.
This exhaust gave a BIG SOTP feel!!
LRS upper an
lower control arms, not bad for the price but even with greasing they squeak
Lakewood driving shaft loop. no performance just safety
SCT boxed tune. felt a little gain but now I have a high idle issue that bugs me. Took the tune out and problem went away. Put the tune back in cause I wanna go fast
Pro 5.0 shifter a gift from the Gods!!
I have had several of these over the years and LOVE them all. only down fall is if your tall (I'm 6 foot) and sit with your seat farther back you have to reach to get third and fifth. My right shoulder has to come off the seat to reach these gears.
Steeda pulleys easy install took off alternator pulley B/C of charging issues. noticed a small gain. Good quality pieces, better than factory.
Ford Racing 4:10s Great mod makes the car accelerate like a monster.
Nitrous Express kit 100hp dry shot pretty easy install took about 4hours. LOTS of grins
BWD adjustable fuel pressure regulator 45psi N2O supporting mod
Autometer 5" monster tach. I know some of you will laugh at this cause its a Honda mod but the factory tach is off. Mine was off about 400 rpm at the big end
255hv fuel pump no power gain just did it to support the nitrous and other future mods
Double cross sub frame connectors, made the car feel stiffer and got rid of a few squeaks
24lb injectors also did to support the N20
Modified stock clutch. bought a new stock replacement clutch kit and had new springs put in it. Has a lite pedal feel and holds just fine
Steeda adjustable clutch quad and cable. I stretched the factory cable so I replaced the whole system. Nice piece and a pretty easy install.
2.5 inch Cobra R hood I know this is a look mod but it also takes off weight making it a go fast mod.
MSD coils did these with Ford Racing 9mm wires and Autolite plugs. I know I shouldn't see any gain with these but I did feel a little. Guessing my old ignition was well worn.
Mobile one synthetic oil. frees up 3-5 hp making it a performance mod
1/2 fuel rails, also a N2O supporting mod
BBK Gripp strut tower bar really nice piece, fit well. The front end felt firm when pulling in and out of steep drive ways and when cornering
Aftermarket rear sway bar but I can't remember the name brand....
LRS polyurethane motor mounts.
Highly recommended 3/8ths thick steel BEEFY looking. PITA to put in, but thats just cause of the 4.6
180 thermostat to help keep detonation at bay....
More to come but out off money..
