Truth about NPI Vs. Pi

Uncle Humjaba · May 22nd, 2008, 12:00 AM

I'm still waiting for there to be actual aftermarket heads... not just p&p pi heads...

Casper98GT · May 22nd, 2008, 12:02 AM

No real need for them yet i guess. People just modify what they already have. Older cars had cast iron heads and such, there were a market for them. Not anymore

MustangMatt96GT · May 22nd, 2008, 12:08 AM

i doubt there will be an aftermarket head for a while. Especally with the 3Vs responding so well. Trick Flow had some in R&D but i havent heard anything for a while on them.

MikeD05GT · May 22nd, 2008, 11:23 AM

good call matt...the 2v's are kinda on the way out and going to be outdated in a few years i bet...the 3v is such a good engine and responds so well...

if you got a cobra engine in your car... you have a 4 valve engine, pi heads are 2 valve, it wouldnt work.

It probably has the ford racing blower, based on an eaton m90, they made it for NPI and PI. Its discontinued now.

ndfrspd · June 17th, 2009, 01:31 PM

good he copy and pasted cause everyone else is too dumb and wouldnt have seen it. thats why you just do a whole engine pi engine swap. if you dont see gains there then you are a retard. the difference between a stock 215 hp motor or a stock 260 hp motor. come on.

6'7 and 280lbs? Did you get fed steroids growing up? Not too many people talk shit to you do they? lol

fsttang96 · June 21st, 2009, 10:26 PM

Im confused now !!! I thought if you were going to put a PI intake on NPI heads you should use the PI gaskets due to using all the silicone around the intake ports when using the NPI gaskets ! Thats what Casper98GT said on his sticky !!! I need to know witch is the way to go since I am doing the PI intake swap in the near future !!!
