    Default Police Car Junk Yard Special

    I recently found a '87 police model (pretty rare in my neck of the woods) at a junk yard. At the time, I only had enough time to pull the rear anti-sway bar (very sweet, I might add). If/when I go back, I want to have a list of police package parts to look for. So far my list of police mods are as follows: Rear sway bar (taken), rear axle (better gearing?/better rear brakes?), larger front brakes, dual exhaust, stiffer rear springs, upgraded wheels, 5.8L engine (out of the question for me).
    I've never come across any diffinitive list of '87 police package upgrades, but have put together this list from what I have heard from others, and from personal experience. What I would like to hear from you guys (and gals), is what parts (if any) I have left off the list, and which of these parts are worth taking off a junk yard car. I am looking for not just drivetrain/chassis/suspension parts, but also such things as aluminum body panels, or upgraded electronics (engine or otherwise). Any input is appreciated.
    All stock \'87 GM--except for the sound system! Alpine V-drive CD deck, Infinity Kappa separates up front, Blaupunkt coaxials in back, Alpine V12 5 channel amp in the trunk, with a 12\" Rockford dual voice coil sub. All this with complete high quality custom wiring. Kaboom!

    The rear brakes are bigger, the fronts are not, though the front calipers on the PI's are bigger. Police gearing bites the big one. Unless you want the best for highway cruising. The exhaust is slightly better, but a custom exhaust will get you more performance. Pull the hangars off the frame though. The 5.8L is a good motor, but is lacking in power stock. (as is the 5.0L) I wouldn't really bother with the springs, they are pretty cheap, and used springs could cause problems..

    No difference in the size of the front brakes, but there is in the calipers. The rear brakes are larger and wider. Should also have a heavy duty transmission wish an extra clitch in the direct clutch pack.

    if you see a gauge cluster in the dash, grab that too. Those are hot items and will go on Ebay if not here.

    Get the front bar. Its a solid 1 3/16" unit. If you don't want it, I do.

    Axle MAY be geared better. Look on the door sticker at the ID tag. AX code K is a 3.55:1 limited slip. Or look underneath on the rear's tag itself, 3L55 is limited slip. Yeah, they do have bigger rear drums, but you could get a better upgrade from a 90s model by putting rear disc brakes on. Standard drums are 10", PI models got 11".

    Not sure the PI front brakes are bigger/better. Someone else can confirm this but I was under the impression that all box body cars had the same brakes. Upgrades would be 95-97 fronts if you want to keep the 15" wheels, or 98-02 if you don't mind going to a 16" wheel.

    dual exhaust: swap on a set of Mustang or Mark VII shorty headers, the Mustang/Mark H pipe, S10 mids, and you have better duals than the stock stuff. The tailipes are useful if in decent shape tho. Grab the driver's side one if its any good unless you can get a new set of tails bent for you car.

    Both the front and rear springs should be stiffer, but if you're gonna bother, just buy new. You can have a set of brand new springs for under $100. My cargo coils cost like $62, if you want really stiff, go wagon or wagon cargo coils. After 18 years of abuse they probably aren't as good as they once were.

    engine electronics will be useless to you. These things were a variable venturi 2bbl carb with some bizzare electronic smog control device called an MCU. Other than the fact they can be easily replaced with a normal 2bbl carb, I know nothing of it.
    most of the rest of the electronics are standard-ish for the year, nothing is really better on the PI models in that respect. PI cars are actually pretty bare bones so other than maybe the groovy spotlight and a big(er) alternator you're not gonna get a whole lot. Oh, and its an easy upgrade to a newer 130 amp internally regulated alternator instead of the 100 amp external model thats probably on the PI.
    I think the radiator is supposed to have better cooling capacity, but not sure I'd trust an unknown 18 year old radiator in my car.

    I thought the PI front bars were 1-1/8", it's the wagon front bars that are 1-3/16"

    Different than a CFI one I take it? Never actually looked under the hood of a PI.

    Police and tow package cars got a heavier frame. they are stamped "HD" on the drivers side near the rear tire. cars with out the Police or tow package are stamped "STD" in the same location.

    Police front brake calipers are the the same size as civilian models (73mm), but use a steel caliper piston, which requires a different brake pad because of the inboard clip being different.

    Some Police and most tow package cars got 11" rear brakes, but I have seen some with out them. you can easily identify 11" rear brakes because the drum are smooth, while the 10" drums are finned. 10" drums are also wider.

    I would advise not spending the money on the Police car coolers, Most are broken and hacked and most of the factory replacement parts are obsolete or expensive when you can find them. you can get better aftermarket coolers for less money IMHO.

    While the police rear sway bar is unique and makes a noticable improvement in handling, there seems to be no guideline as far as the front bar is concerned.
    I got all the suspension parts for my car from a 90 model P72 sheriffs car in the yard a few years ago. the front bar from the police car was the same 1 1/8" bar that on my car originally.
    that seems to be the norm from the other cars I have seen at the salvage yard. I have seen a couple wagons with larger hollow bars, but most wagons that I have seen have a 7/8" or 1" bar on them.
    I would assume finding a wagon with a K code rear end and 11" rear brakes would indicate a heavier suspension and presumably a larger front sway bar, but I havent seen any yet.

    Define smooth rear drums, like totally without fins, or with very small ones? Mine have fins, and they're the larger ones. Not sure if they're identical to PI ones, but they are bigger than standard. Takes different shoes and such.

    I also wonder if the universal joints on a PI are larger. Anyone know? There has also been talk that the PI used a long tailshaft transmission, in other words a Lincoln tranny.

    It's actually the same according to my collison pages, do you have one in good shape?
