Valve springs + K20 intake manifold

[sodaz]

hehehe couldnt help myself... just ordered the RBC from a DC5 RSX/EP3 CTR...
it comes with:
-RBC INTAKE MANIFOLD
-"KARCEPTS" RBC ADAPTER TO MOUNT STOCK THROTTLE BODY
-GASKET - BETWEEN RBC MANIFOLD & KARCEPTS ADAPTER
-GASKET - BETWEED KARCEPTS ADAPTER & STOCK THROTTLE BODY
-VACUUM LINE - TO CONNECT RBC TO STOCK VACUUM FITTING
-HARDWARE TO MOUNT STOCK THROTTLE BODY TO KARCEPTS ADAPTER PLATE TO RBC MANIFOLD
(im not sure if ill need the TB adaptor as i think the RBC used drive-by-wire thottle anyway?)

i should have it within the week, ill install it when i put on my Hondata heatshield gasket, and do my throttle body coolant bypass

should work well in conjunction with TODA headers and K&N CAI...

now i just gotta save up for skunk2 stage 2 cams and jtune mild reflash

Did you order the Euro R intake manifold? I remember reading somewhere that installing it on the K24a engine caused it to lose power. The shorter runners are designed for high end power which suits the K20a but not the K24a.

i think its the same as the euro R, i know its different to the K20 manifold off the S2K and ADM DC5, they use a more snail like intake... yes the shorter track will lose power low down, but it gains up to 7hp top end... and when used in conjunction with CAI, headers, and reflash, they obtained about 15hp gain... it'll also give me more room to move when it comes to cams and headwork...

The stock RBB manifold is uses a long narrow runner which is good for torque, whereas the RBC intake from the Accord Euro R uses shorter fatter runners optimized for high rpm breathing. The RBC intake is a direct replacement for the RBB

you can see below the intake tract on the RBC is actually about the same length as the PRB, but doesnt snail around, allowing for free'r flowing air

i have the stage 2 Skunk cams in my k24 civic, and i love em. i have standard headers which really restricts room to me to move, but mid-range to top-end is pretty intense, heaps more torque. you wont be disappointed if you decide on them.

personally, stage 3's are nuts...send a PM to Dr Honda for more information, he has them in his civic.

good luck

did you do any more engine work besides cams? like valve springs or anything?

thanks for that, good to see a real life example

who'd you get to install them?

Tb adapter got nothing to do with drive by wire system.

people use karcept TB adapter to run K20A throttle body on RBB and RBC intake manifold.

i was going more down the line that the adaptor was made for non DBW TBs... and i was under the impression that the RBC was made for DBW TBs (CTR and ATR) so i wouldnt need it...

Interesting! Good luck mate. Let us know how you go with it.

cheers

im kinda in a modding mood today... as soon as my bloody TODA headers arrive (still waiting after 8weeks!) and i get the intake on, ill go get her dyno'd

Is custom tuning needed with Cams? or would hondata do? Might pay to see what they come up with their cam/flash/extreme package we know how long this might be....

[EUR003act]

thats exactly what im wondering!

im pretty sure id need alot of tuning for stage 3... but would i get away with the jtune mild flash for stage 2 cams?

[LUD35]

i have skunk stage 2 cams with stage 2 titanium valves and retainers. Dr Honda built the motor for me.no other internal work other than the cams and ARP head studs.

im running a k-pro, so no there arent any "custom" tuning specifically for the cams.

Tb adapter got nothing to do with drive by wire system.

people use karcept TB adapter to run K20A throttle body on RBB and RBC intake manifold.

From the TSX forums:
since the RRB and the RBC are newer, they require the use of a Drive-By-Wire throttle body. Since the K20A and other models are not Drive-By-Wire, the throttle bodies do not bolt up. You will need an adapter plate used in conjunction with a K20A throttle body and cable

the adaptor plate is only for non drive-by-wire TBs... so i wont need it for the k24a
