Which would you guys do? I've been told that with the Skunk2 IM...you'll lose low end power. What about if you modified an ITR manifold to fit? Is it pretty much pointless?

 

there basically the same thing
just the itr can only fit on a itr and b16 head
skunk has made one to fit the b18c1

 

The Skunk2 manifold is designed to mate up with a variety of heads (see below). The ITR manifold flanges are shaped differently so you cannot simply bolt one to your Integra. As you may know, the manifold is shaped differently than the GSR manifold so it is able to flow with less restriction.

Integra GSR 1.7L DOHC VTEC 92-93
Integra GSR 1.8L DOHC VTEC 94-01
Integra GSR 1.8L DOHC VTEC 97-98, 00-01
Integra GSR 1.8L DOHC NON-VTEC 90-01

isnt the skunk 2 one port and polished?

 

Yes I believe the S2 manifold actually flows better than the ITR manifold.

 

Actually, it not, but the opening for the TB is already bored out to 64mm. I measured when I thought I need to bored out for my over-bored TB.

 

I just had someone email me saying that when he had it on his 2000 gsr...the power seemed to be there at 4000-6500...but afterwards...didn't seem to wanna go to 8000 anymore. Also told me that the vtec crossover wasn't noticeable anymore cuz it's single stage. Says I should use the Skunk2 if it's turbo or high modified internally.

Anyone else have any problems?

 

i hve the ITR

 

For stock GSR cams, I would say keep the stock manifold. But with my ITR cams, it made difference up top. The car pull alot longer than it did with the Stock manifold.

 

VTEC crossover isn't noticeable in the first place. What is noticeable is the secondary intake runners opening around 5700rpm, which of course doesn't happen w/ the S2 manifold cuz the runners aren't there.

 

The differences between the two are minor. I doubt you will notice a huge difference between the two. The big advantage of the Skunk2 one is the ability to bolt one to B18C.

 

I love my skunk2...

The skunk2 is not a good mod to be done first though... if you have done nothing on the intake side (CAI, bored throttlebody) then it will not be as noticeable...

The first thing I noticed when I installed it was the instant tone change on the intake... I also noticed nice gains on the topend... Of course I would notice much more with some better flowing headers...

The skunk2 is a great part, but it is only one thing in a good amount of mods to prepare to get the best gains from it...

 

i had i/h/e on my gsr and my friend's gsr could beat me by a car length.......after the s2 manifold and tb, i was able to beat him by a car length.....the car also pulls all the way to redline now......with the stock manifold power would drop offat around 7600

absolutely not true......mine got a lot louder........you can barely hear the vtec x-over with the stock manifold......its the 2ndaries that you hear
