Does anyone have any test info or experience of how the RSP compares with the RRC and RBC. There are a few vague tests on the net but nothing solid about the RSP.

I have the RSP, and was going to swap for skunk2, but Hybrid Racing say RSP is best and just as good as Skunk2 - what say you?

Which intake manifold does our FN2 have stock? RSP? I reckon a Bored RSP with 74mm Skunk2 TB is the best way for performance & save some price! That will be my next plan on my FN2 :D!

Yes RSP. I did a test of RSP with 70mm TB and RRC with 70mm TB and the power curve and torque are the same till 7400rpms, after that RRC is beating RSP by 11hp.

Don't know how bored RSP will behave.

The RRC was definitely better when I swapped, forgetting any "bore"-ing work.

When you guys say boring out, do you mean the tb end so it matches the tb or are you meaning something else?

In which case I did this to my RRC manifold, and Ive done it to my charger, couldnt really notice any difference after on the charger. I never tried my rrc before it was bored out

If anyone has one laying around unused on a shelf, I'm looking for a used RSP intake manifold. Unfortunately we can't seem to get them here in the United States. It'll be going on a K20A2 from a RSX-S so I don't care if the water neck has already been cut off.

Please PM me with a price shipped to the USA, zip code 53151.

Thanks,
Jeff

For me in full N/A mods including camshafts (but with bigger TB) the results were :

11HP increased on RRC+Spoon 70mm TB, but till 7400rpm no difference agains RSP+OEM TB
