The JDM civic type R? They use the RBC manifolds. The Aussie civic type R uses different manifold. Cant remember the code for it but the yanks have had RBC and that manifold on the dyno and it shows great results.

JDM k20a over the AUSSIE k20 - cams, slightly more compression, manifold (slightly), ECU (there fuel is better), headers.

yeh, as stated i said FN2R not FD2R (although i think the FN2 and FD2 use the same RBB manifold)

No, RBB is used on the Accord Euro. FN2R uses RSP. You can tell from a photo of the engine.

Edit: You're right, JDM Civic Type R uses RBC

QTB's, able to use them with stock motor, or are cams required?
also with the headers being on the firewall side, does that free up alot of the restricton as apposed to a normally mounted motor?

We ran ITB on a stock internal jdm k20a before without aftermarket cams.
