Have a Bone stock 1996 Crown Vic (civilian model), only mods are dorman intake because the old one cracked. Looking to get 350 rwph. Not worried about emmisions. Any sensors that can take off is ok by me. Thinking I will need exhaust and cam. The transmission will need to be done cause it shifts smooth and has the stock coverter. This is all me guessing, wanting to no all the moods and parts I need to get thanks guys and take it easy on me lol |

You will need much work to get to 350 rwhp. A newer PI 4.6 2v with forced induction, or a 4.6 4v highly modded(possibly forced induction), or a Chevy engine will get you there.
A PI 4.6 with heads, headers, cams, larger injectors, larger TB will get you around 300.
Do you have a budget for this? |

Go to www.crownvic.net or www.crownvic.ca and see what others did to get into the area. treat it like a Mustang motor and you can get there with as much effort as doing a Mustang. A blower or turbo will get you beyond that level quickly.

Yes a very low Budget lol. Maybe I will shoot for around 300 rwph. I been thinking that I would like to start with the transmission. From the factory the set them up for comfort rather than performance. Any ideas on parts and there to get them and selecting a converter. I will be doing the transmission myself. Next I will be upgrading the rear diff. Thinking of 3.50 ratio, will the stock rear diff a good one or should I get a different one. |

There is a write-up at www.crownvic.net about what you can AND can not do to the CVs before you are forced to begin having the PCM retuned.
If I recall correctly, you can install some sort of CAI (you definitely want to get colder air into the engine) and you can change your rear end gears to 3.55 ratio. This can be done without a "tune". Any ratio of the rear end above 3.55 needs to have a "tune". (The "normal" CVs have 3.08 rear ends, and the P71 Police Editions use 3.27)
Next, you can replace the non-PI heads from our engines with a set of PI heads from the 1999-2003 engines. This will kick up the compression ratio to where you will need 91 octane or better gasoline. http://www.stangnet.com/mustang-forums/threads/pi-headswap-write-up.717166/
You can replace the throttle body with one from a Lincoln Aviator. It is a direct fit, but has a smoother flow pattern through it. The plenum just needs to be polished inside....(The 75 mm throttle body/plenum assembly they sell for Mustangs is too large for the street, unless you plan to run 3500 RPMs or higher all the time. The Aviator TB is about 2 mm larger than ours as stock.)
The CAI setup I have on mine are tubes from Spectre Performance [http://www.spectreperformance.com/] (at Pep Boys) with a cone filter at the end. I then boxed in the cone to prevent hot air from the running engine getting in and opened the small hole on the metal clip that holds the headlights. This lets more cold air in and with the air filter boxed, it is all available. (There is someone on ebay who sells a "CAI" setup for CVs, but all it consists of is the tunes and couplings with a 8 " filter. For $50 it's not too bad, but all it does is replace the air filter and pipes from stock to chrome.)
Here are a couple of links for getting parts. But you should go to www.crownvic.net and see what others have already done to theirs. There are several write-ups in the forums where people will tell you what does and doesn't work on the CVs.
http://info.automotix.net/usedengines/ for used parts nationwide.
www. RockAuto.com for new parts at a discount...Their prices beat everybody, even with the shipping. But this is for "planned" projects, like you want to replace your radiator. So you order the radiator and all the hoses ahead of time. And about a week later, they all arrive at your door.
http://www.1010tires.com/Wheels wheels and tires..Most of the 1980-1999 Mustang wheels with with no problem. Any local tire shop can help you with your choices. There are THOUSANDS of choices, if the backspace and offset are correct. And some of the companies can grind down the wheels to custom set you offset. A 9 inch wide wheel will fit all around with no problems, but a 10" is for the rear ONLY.
http://www.crownvic.net/drock96marquis/index.htm good website
Now for your transmission. A good rebuild will work. The 4R70W are tough transmissions (also used in the trucks). Go checkout http://www.tccoa.com/articles/tranny/. This is from the engineer who designed the transmission.
For a converter try http://www.transdepot.net/AODE4R70W-Torque-Converter-1700-1900-Stall-Lockup_p_161.html. There are only about 4 companies with websites that make better converters than what comes from Ford. And avoid the "racing" converters. The stall speed are way too high for the weight of our cars.
But mostly join up and read the forums at www.crownvic.net. You will learn from the best.

Find out what your rwhp is now, then work from there, 300 will run you a few grand(much more if you can't do the installs yourself). PI upgrade a few hundred, cams a few hundred, TB a few bucks at junkyard, injectors and pump a few hundred, exhaust so the car can breath properly will be headers for best flow and cost a pretty penny new.

I've had 3.73 and loved it, the stock diff is good(my '05 CVPI came with the 31 spline trac-lok) and even better if you can get the parts local and install it yourself. I did my diff myself this time around and saved the install cost(lowest local was $250 with me supplying all parts), all new parts would run a few hundred(rebuild kit ~120 with all bearings and seals, gears ~200, fluid ~50, trac-lok unit ~200 used) |
