The pleneum is much bigger, and it is a single stage intake manifold. The stock GSR manifold is two stage. it uses shorter runners at low RPM to make better torque and gas mileage, and long runners at high RPM. At 5750rpms, the butterflys open and switches over to the long runners. The GSR is the only b-series to do this. The Skunk2 manifold is basically a copy of the ITR intake manifold, with some differences. The ITR manifold (which is a single stage, like the Sk2) is designed for better high end response. The skunk2 manifold on a GSR will hurt low end power considerably unless the motor has sufficient modifications to use it. In other words, its no good on a stock motor since it will hurt low rpm, with minimal effect on high rpm. The stock manifold is good (In my opinion) until youre either boosted, or have a serious NA build. For a boosted application, the best IM is the Edelbrock VictorX, but the Skunk2 is a step above stock.Kuchtaboy said:what's better about the intake manifold over stock? (just wondering)
This is backwards. The long runners are used to produce low rpm torque and the short runners open up to help high rpm breathingSirfallsalot243 said:The stock GSR manifold is two stage. it uses shorter runners at low RPM to make better torque and gas mileage, and long runners at high RPM.

Yep, youre right. Sorry about that- the long runners are for low RPM, the short runners are for high RPM.dc2GS-R said:This is backwards. The long runners are used to produce low rpm torque and the short runners open up to help high rpm breathing
And yes, an aftermarket IM on a car with only bolt-ons will make it slower and reduce lower rpm power
SOLOTR95 said:Ok I Bought Those 2 Parts From Skunk2 And A Aem V2 Intake. And I Got Dc Race Headers With The Skunk2 Mega Power Exhaust On The Way. Also Got Planed Some Different Camgears And Camshafts. So What Should I Do Then.
Yes, with those parts listed thats quite a N/A set-up in the making. But obviously their is always more to be done.dc2GS-R said:I would definitely get some cams and do some tuning to bring those parts out to there full potential
okay, so its really no advantage... but then why does the ITR have it this way? Wouldn't it make more power with the 2 stages? I knew about the gsr 2 stage runners, Dodge does the same idea with their Magnum heads.Sirfallsalot243 said:The pleneum is much bigger, and it is a single stage intake manifold.

Because the Type R is built and tuned for all out, high rpm power. Plus it makes up for it in other ways........better cams, ported head, higher C/R, etc.Kuchtaboy said:okay, so its really no advantage... but then why does the ITR have it this way?
Hondata would be perfect :thumbs upSOLOTR95 said:Yeah Tuning Is On The List For Sure. I Was Thinking About Getting A Hondata S300.
