I've got a 1994 Crown Victoria and I'm looking for options for part interchangablity. As you've probably noticed there isn't much of a supply for aftermarket parts for our cars. Does anyone know of other cars that use the same engine components as ours specifically superchargers, headers, cams, intakes ect. your standard upgrade performance parts. Please any lead or ideas would be killer!
You have a non-PI 4.6L, so you can use any engine components from a 1996-1998 Mustang.
I'm not positive on the headers, but if you contact Hooker, I'm positive they have a header that fits- then, you get to say you have a set of Hookers in your ride. :hy:
The rest of the exhaust system is something to run custom, anyway. Order free-flowing cats and mufflers off eBay and have a muffler shop install them (be sure they warranty their labor).
Transmissions- You can use a shift kit from the same year Mustangs- easy install and they provide great results and dramatically improve the life of your tranny.
Suspension- get P-71 suspension parts. That's the Police Interceptor- I think they were upgrading suspensions back then, but don't hold me to that.
Rear-end: I don't believe in re-gearing, but if you want, you should have an 8.8, which will take any locker or gearset available... I'd say 3.73s or 4.10s if you're going to do it. I'd lean more toward 3.73s, but definitely do not go over 4.10s. Again, I'm not a believer in re-gearing.
As for wheels, you need aftermarket. Mustang wheels will fit with spacers/adapters, but that looks funky and it throws off your suspension geometry, resulting in bad alignments and awkward tire wear.
I'm pretty sure I'm on-hit with all that, as I am almost positive the CVs had the 4.6 in '94. If you have a 5.0, then you can use engine parts from the 1987-1993 Mustangs and any shift kit for an AOD or AODE, depending (should say on your transmission pan).
Check to be sure your intake opening is on the passenger side of the car. If it is, then you can run Mustang intakes. If not, then swap to Mustang intakes by relocating your battery and such, freeing up the space on the passenger side for your air tube and filter. BBK makes good intake manifolds, throttle bodies, MAFs, and elbows. I'd say start there (doing the exhaust first, of course), then find a set of used P.I. (Performance Improved) heads (don't bother with the 4v heads- too expensive to work on and it's WAY too much conversion from a 2v motor) from a '99+ Mustang and get them ported and polished. If you have the money, have them do a 3-angle valve job (5-angle isn't worth the price difference compared to the performance enhancement). You'll need larger injectors, fuel pump, and an adjustable fuel pressure regulator at some point in there. That should satisfy you. If not, Google for some supercharger companies and find out who makes a kit for a CV.
Does that help? Any more questions?
