Thread: N1 manifold kit?

What are the gains on it and is it worth it? Is porting the head to the manifold ports increase flow? Im almost done with my VE list and wondered if I should toss the mani kit in there.

NA it isn't worth it, save the money from that and buy a nice 4 to 1 header.

any info on the gains?

I know Mike K did some testing and he didn't see much more then a maybe 3 hp if I remember right but don't hold me to that. Just do some porting of the stock mani and tb and port match it and call it a day.

ill have to check that out. Thx+

^^This guy is 110% right

if the motor isnt in the car yet.. do it an match port the head. the t/b is 70 mm on the n1 manifold an dwarfs the stock sr20ve ones.

So just port everything out (mani,TB) and its about the same......hmmmm ima see how much that is.
