I would like to know if anybody got their hands on a RSP intake manifold? Did you test it against a RBC intake manifold?

The RSP intake manifold is a three piece design that has much longer runners (about 2.5" longer) and a slightly bigger plenum than the RBC intake manifold. It is basically an improved design of the RBB (TSX) manifold, since it produces great top end power as well.

Isn't the RSP a dual path manifold, like the old integra manifold, where a flap/valve opens at certain rpm to allow a wider, shorter air path, while at lower rpm the air takes a longer, narrower route?

No, it's not a dual path intake manifold with throttle valves incorporated to vary runner length. That's what I thought at the beginning but several people from the UK that have the FN2 confirmed to me that no valves existing inside the manifold.




Like I said before it's a three piece manifold. The top piece incorporates the runners, the second piece introduces additional runner lenght inside the plenum, and the third piece closes the plenum space. This manifold costs about $700 according to a dealership in the UK.

Oh, cool. So what's the chamber down below the main plenum? I think that's what got us all thinking it was a dual path manifold.
I believe what happened is that the back portion of the trumpet from the runners was not inhaling enough air so they where restricted from making the manifold plenum wider in order to accomadate this restriction, due to space so they added a second floor in order to feed the back portion of the trumpet.

Why? It looks closer to a K20A2 manifold than an RBC. It goes into the same pattern that the JDM CTR gets the newer-RBC styled manifold since the Euro CTR has not gotten the same goodies. Of course I'm speaking of the JDM CTR K20A versus the EDM CTR K20A2 in the EP3R. I just see this as an extension of that - give them an "R" . . . but only in name.

AROUND $800 us for one, if someone wants to take the plunge
That's about the price I got from a UK dealer. Isn't there a honda site in Europe that sells at a wholesale price?

Even my friend at the honda dealer cannot get better price. The manifold looks hot for sure but I would really like to see it vs a rbc on a 280whp k24a... lol

I'd still have to say.. for the price your better off with an aftermarket.. until then theres gonna be a lot of overspeculation until someone is willing to get their hands on one of these..

Yes, valid point. The JDM R has yet another manifold (looks like an RBC, but is a bit different) and that engine makes more power than the Euro one. The JDM engine does have improvements other than just the manifold, but the point being that Honda surely used the OEM manifold that is capable of making the most power when they built the JDM version.

The new Japanese model's engine output is higher than the European version's, with 222bhp (225 PS) being developed at 8,400rpm and 159lb ft (215 NM) of torque peaking at 6,100rpm (versus 198bhp at 7,800rpm and 142lb ft at 5,600rpm for the European model).

Okay, looking at the photo in the PDF, I'm inclined to think that the bottom passage is a sort of catch can for the PCV. There is only one port into the main chamber from the lower one, and the lower one is not connected to the TB.

The air from the TB must flow around the ends of the runners, so it does seem much like a PRB/PRC.

Give me the Honda part#, i go ask my Honda dealer. I am living in Switzerland (Europe).




On page 19 of this pdf file, you can see the three pieces of the FN2 intake manifold.

It's a hybrid between RBC and PRC. :silly:

That's can be good

intake manifold 17100-RSP-G00
other half of the plenum 17101-RSP-G00
gasket for the "power plenum" 17102-RSP-G01
additional runners inside the plenum 17103-RSP-G00

Can you get your hands on a used one. Maybe you can convince someone to sell his for a RBC intake manifold.

It also sounds like the intake manifold contains the plenum but you are going to have to ask,.

On the subject has anyone used the 2007 JDM FD2 intake manifold?

i would have thought that would have good gains on that too. :rolleyes:
I thought the conclusion for that was it couldn't be used for now cause it was missing something. GT Motorsports or someone sells it.

The Idle Air Port.
Who cares. You could make one with a drill and Dremel, or hook your IACV up to a vacuum nipple like I did with my ITB's. That is not a blocker.
