My brother has a 93 cvpi and we are thinking about changin out the tired engine.. Where is the best place to get a PI long block. I know I would have to use some parts off the engine comming out. or really would just need the block with heads..what problems would I see comming using a PI engine in a 93..

I'm pretty sure the '93 EEC will run the PI motor.
Might need to get a tune, though.

depends - do you want a new engine, rebuilt or used? If used, check out: http://www.car-part.com/ and find a local yard near you. Keep in mind, to upgrade to a PI (Performance Improved NOT Police Interceptor - a newer head/intake design) engine, you'll need a 2001+ donor motor and you'll need the computer, most likely a complete harness and a few other things. I'm sure someone will correct me and post exactly what's needed. Also, for a direct swap look for either 96 or 97+ nPI (non-Performance Improved) motor which will have the newer style valve seals.
well from what i heard..to run a PI motor in a NPI car..really the only thing that has changed is the intake,heads and well all the sensors...however..i know i would have to change over the fuel rail,intake,and coils due to bein a non-cop engine. but couldnt i just change over the coils and plugs but still use the intake i know it sits sideways as to how it sits now but isnt it almost the same design..

I've done a little searching - there is fairly current thread in the "Modular High Performance" forum on a very similar topic, swapping a PI motor into a '94 cv - linky. BTW, the civilian vic motor and police interceptor motor are identical. PI and nPI mean Performance Improved and non- Performance Improved. It's basically different dish on the pistons, different heads, intake and tune. Search and you will see many threads discussing this topic to death. Here's a link to a article in the BOK (Body of Knowledge) link regarding fixing the valve stem seal problems in pre-96' nPI motors.
thanks...btw just some info i know PI and NPI..have read alot about them. I even know that you can take a PI intake and cams and put them into a NPI and make a little more power then the PI engine

no problem. the only reason I spelled it out was when you stated:
snip ...
and coils due to bein a non-cop engine.
... snip
sorry, when "non-cop motor" comes up in a nPI vs PI discussion, the first thought that comes to mind is the person who stated "non-cop motor" is confused between a CVPI and civilian vic.
Also, if you're replacing the motor, you definitely do NOT want a cop-motor. Think about how they are treated in their service life and how many idle hours it may have on it - you can't trust mileage alone. Granted, even with a low mileage civilian vic motor you have no idea what the history of the motor is and how it was maintained. If/when it comes time to replace the motor in my CVPI, I will first look for a lower mileage non-CVPI motor, but it all depends on what's available at that time - I'll cross that bridge when I get there.

not cop as in police....cop as in coil on plug

The 92-95 models will require more work due to the aluminum intake system. You will need some parts from 96-97 models like the fuel rails, throttle cables etc and some 95-2002 exhaust manifolds. Engine harness needs reworking to fit the newer intake.
You will need to adapt the PFE sensor to run on the DPFE/EGR supply tube

Why don't you drop a 5.4 in there?
