PI or NPI What in the world

[illone]

Ok here goes I just got a 98 G.T that is said to have a 00 motor. Well I needed a belt and come to find out the car calls for a 98 belt. But i saw somewhere on this site that if the oil filler neck sits on the passenger side its a pi motor and if its on the drivers side its a npi. Well my oil filler sits on the pass side and the intake manifold is plastic with one sensor hole, from what i can tell it looks prety much like a npi intake. Oh and my car has coil packs that sit to the front of the motor. I really need help to find out what in the world this motor is so i can order a now cracked intake. Any help would be thankful.

Coil packs that sit in front of the motor? Wired?

If your oil fill is on the passenger side then you have Windsor heads, but not necessarily a PI engine or even PI heads. The coil packs could have been carried over by using the original harness, the heads don't care where the spark comes from so long as they get it. The front cover could have been reused from the original engine as well, in fact the 3 bolt tensioner is preferred to the single bolt tensioner. And the fact that there is only one sensor tap in the intake tells you it is a PI intake as NPI intakes have two sensors.

My guess is you have a PI H/C/I swapped engine.

If you want to consider power ladders at some point, your compression is about 10.2:1 so nitrous is good and a centrifugal blower is ok, but I would not use a turbo or a positive displacement blower unless you build a shortblock to reduce compression to at least 9.0:1.

You are probably around 235-250 rwhp if you are otherwise stock. Lots of info on this forum about this setup, just do a search or start a thread if you have a question.

its prolly pi swapped with windsor heads

 

[Mr. Rustypwnz]

since it has the old timing cover still on it

so do i have to go thru the head ache with the rtv or do you guys think its a direct pi swap.

the oil filler can be on the passenger side on either a Romeo or Windsor...my 2004 Romeo and the original 2000 Windsor both filled on the passenger side...and with a head swap they could be on either side.

the easiest way to tell the difference is by counting the cam cover bolts: 11 bolts = Romeo, 13 bolts = Windsor...but that doesn't help with PI or NPI

the car doesn't appear to be a PI intake, but I don't think anybody has come up with a way to ID PI heads easily without removing the intake :-/

I guess that's not much help is it?

its got windsor heads, its pi'd
