is there a differnce between a 96 intake manifold and a 03 manifold....and are they interchangable?

 

tha gt models...(sorry)

 

Yes, the 03 is a PI intake. Which have bigger ports and taller runners than your 96 does.

 

You can put the PI intake on your NPI heads and get some nice gains. I can't remember how much for sure. You just have to epoxy the gaskets in certain places for it to work. http://forums.modulardepot.com/showt...threadid=18636 If I didn't have the money to do a head swap I'd do this and add the PI cams instead.

 

I've got a couple more threads

This is the parts list for the intake swap.

This is where to put the sealant for the PI intake.

sweet..those threads are awsome...thanks

 

does anybody know the gains i could expect from this swap

 

The first guy to dyno it got a 15rwhp increase. If you add PI cams you'll have more HP than the 99+ guys.
