Truth about NPI vs PI

Yes! The usual crew here at sn95 will be able to walk you through it.

 

Excellent write up, I'm new to the Modular world and looking to make some respectable number this winter. Thank for the information.

 

Yup, as long as you find some good instructions and follow them to the t. Intake is extremely easy, cams are not hard as long as you pay attention to what you're doing

 

OK-I think I got it....nope...wait...what?

On track with the original post, are you telling me the 99-04 are always PI from the factory? We just added our first modular to the fleet and want to make sure we have a full understanding. What components are PI on a 2001?

 

Intake heads cams... full pi motor.

99-04 are all pi motors

 

OH Boy! Thank you. But now I have more questions than answers. LOL

What are the logical next steps? Tune? Is there any thought on aftermarket Intakes, throttle bodies or cams?

The car has some sort of headers but i couldn't get a close enough look at them. They didn't really impress me though. (I don't take possession of the car until Wednesday)

Also has 3.73 gears.

I'm really thinking "just drive it" until we're ready for the charger?

 

Drive it until supercharger funds are there and slap it on as fast as you can

 

I still love them!

 

Watch it old man

 

And on that note, I'm looking at my '98 seriously for the first time since around '06. I just installed Koni shocks and lowering springs and now I'm remembering the need to wake up this car's motor. I know I'm late to the game, but I'm considering the PI swap for this car-it just turned 100K on the 'odo. I already have the intake installed, and I figure I might as well go along with the heads and cams. Has anything changed with this 'mod or is it still just a matter of finding PI heads and cams, bolting them on and getting it all tuned? I see some vendors that sell fully assembled PI heads, but is there a specific vendor you guys would recommend? I've got other car projects going on so unfortunately I can't get too fancy with the parts; I'm hoping just to pick up stock PI heads/cams and get it all tuned. Advice? Suggestions? Any input is appreciated...

 

Shoot for the '04-up 9thread spark plug holes. Pi heads are known for spitting plugs out due to the 4thread holes in the pre-'03 years. Over torqueing the plugs is a major contributor to the problem and the Windsor made heads are a guarantee problem, be sure to steer from them.

On a side note, npi heads decked to aquire the same static compression ratio and equipped with pi gear dyno's really close to the same power.

 

Also really good advise^

TFS heads with a good rocking cam and higher flow intake puts 400hp to the ground!
