crown vic v8 swap into my 98 ?

[CruizinKev]

found a crown vic 4.6 with auto tranny - about 56544 miles. this is it:

what do you think? it'll fit in my car? what is all needed?

wiring harness, ecu, intake manifold, what else?

my car is a 1998 3.8 with auto tranny.

kmember.

kmember.

he doesnt need a k-member. all 96-04 k-members are the same between engines. he would need the motor mounts still though.

94-95 is one group. all 94-95 factory V6, GT, and Cobra k-members are the same
96-04 is the other group. all 96-04 factory V6, GT, and Cobra k-members are the same

so I need the engine, mustang GT plenum, GT motor mounts, GT wiring + computer, GT dash cluster, 8.8 rear? What about my stock 98 auto transmission? Also will fit?

like i said on 3.8, your autp tranny is specific to the 3.8 and 5.0 bolt pattern. you would need a 4.6 transmission

You'll also need to turn off the pats or have a new key made with the correct pats code.

really? I thought the 1998 3.8 got a 4rw70? the 4rw70 is the same like the 4.6 have?

 

[Untame-d]

4R75W is concidered for the Mustang V8, I'm not sure when that was changed though. T45 is what the GT's have for stick. I think that's what you should go with + clutch. If your up to for a little more work. :thumbsup:

they are the same basic transmission, but the bellhoushing bolts are different for V8's

it is the same principle as to why you cant use a M90 made for a Pontiac Grand Prix on a V6 mustang. same general design, but they have special characteristics

 

[CruizinKev]

okay I see. anybody knows what auto transmission the 2000 crown vics had? I can get the engine with that but don't know what it is.

4R70W, it should fit in the mustang's transmission tunnel

I have some bad news. It will save you a lot of time and money. That is a romeo NPI engine. It is the same engine the 96-98 stangs had in them except for the cams, so they are even more anemic. Crown Vic's didn't get PI engines until late 2001. If you remember, the 9-00 mustangs had windsor PI engines in them.
If you are still hellbent on putting that engine in your car, then you could probably use a computer and harness out of a 01 mustang and it would work pretty well at controlling that trans and the engine.

 

[CruizinKev]

yeah I know its a NPI - but I see a PI swap in the future I'd get that engine and do the PI swap before the motor gets in the car

 

[Untame-d]

It would probly save you money in the long run if you shopped for a PI motor right now. Unless your paying peanuts for that Vic motor.

 

[CruizinKev]

remember I'm in Germany.. its kinda rare to find anything like that over here.. I easily could mod the v6 right now for good power but I want the v8 rumbling sound :headbang: ...I'd even be happy with stock NPI 4.6 power

I'd order up a H/C/I swap from one of the 6banger performance shops before i went through all the hassle of installing a NPI Vic motor in my 3.8 car.

It will probably be faster with a V6 cam, ported heads and intake then the stock NPI would be.

 

[NXcoupe]

that's what I meant, hold out and get an engine with PI heads on it already. I do understand what you are going through being deployed myself, and I imagine they have a hobby shop on base as well with all the tools and such. I would just research it a little more, and it really depends on if this is a deal or not. If the engine and trans are less than 500 bucks, I would say go for it, and then get your PI heads shipped to you. give you something to do when you aren't on duty. We don't have that here, with 7 12 hour days and incoming, there isn't much time for wrenching, and besides, there isn't anything here besides goats and MRAPs
