CV motor question

[duhtroll]

OK all you CV guys --

I have a 2000 CVPI whose motor just took a major dump and most likely needs replacing. I am looking around at used motors and the CVPI package motors are more $.

Why is this and what is the difference? Since this is a work beater, can I just drop a regular CV motor in it?

Thanks!

All the CV's got the better 'PI' heads in 2001.
I don't think that there are any internal engine differences between a CV and a CVPI.
The CVPI's also have a nice oil cooler set-up.
Look for a 2001+ engine and you will get the better heads.

According to some on CVN the 04's CVPIs are the best on horsepower. Whenever the CVN forums decide to come back online you might want to check, there was a post about this subject a couple of days ago IIRC.

What he said.

I'll add that in 2001, Panthers started getting the "revised" intakes with the aluminum coolant crossover tube. This intake also has deeper runners, netting more HP. That's why many NPI Panthers swap PI cams and PI intakes. I did this on my '98.

I think the 01's had a different knock sensor set up so you may need a 01 EEC too. Look for a web site p71 interceptor. I think he covered what's involved in different motor swaps. The oil cooler is just a different casting on the oil filter mount. Save it from your old block to put on the new block. There's a torque sequence for the bolts that the dealer can look up.

+2 on what Joe Walsh and Embassy said. Of course, you could buy Zack's V10 and have a field day with it.

the 04's actually have the same horsepower as the 04,05,06, etc etc, it just had a more aggressive tune, and from what i've heard, the 01-02 Vic's did have PI heads, but a different transmission setup, so unless you want to do a tranny swap too, i think your best bet would be to find a junkyard 98-00 and use that. Then swap the computer from a 99 CVPI into it because it had the best tune out of the 98-00. The difference will be night and day. good luck

FrankJAG - According to some on CVN the 04's CVPIs are the best on horsepower.

That's only because the 2004 P71 got the Marauder-like air-box and 80mm MAF; it's like because ...

• the MAF is integrated with/to the air-box and cannot be detached.
• the PCM transfer table values are different.
• the Marauder combo' has more potential.

Other modern-day variances ...

• 2003+ - knock sensor.
• 2005 - drive-by-wire a.k.a. ETC ( Electronic Throttle Control ).

That's it! Good stuff, thanks guys.
I am sure the OP will like y'alls info as well.

[duhtroll]

Thanks for the info. It's not important what performance it has right now - I have a Marauder for that. It's probably going to get the motor I find the best deal on right now. It's just a work car and I'm not keeping it very long, but it is in too good a shape to junk it.

If that the case then find the cheapest running motor you can find.

[duhtroll]

Yep - those were my instructions to the mechanic doing the swap. I think he'll get a better deal from what I have seen.

you can use the stock trans fine with an 01 motor and EEC.

2004 PI's/05 CIVI and up got a different MAF, i dont think that the old plug will fit the new maf at all.

HUH?

You...you...you...mean that you are going to keep it stock!?...



Good luck with the install and returning your CV to road-worthy status!

[duhtroll]

Noooooo... definitely not stock.

It got a new stereo head unit, new center console, new cb, new radar detector and laser jammer, new headlights, new tires, new air filter, and new oil every 3-4K miles. Now it's getting a "new" motor.

It also got a MM catalytic converter last fall. Now that's EXTREME CV action!

I need some decals for more HP.
