Throttle body question

[K.C.]

anyone here has any idea wat is the use of the extra connection on the spoon tb for B-series?
i sealed it off with a tape at the moment..


The intake arm seems to have a "hose holder" for the hose that suppose to run from the tb:

that attaches the the charcoal canister which traps the expansion fumes from the petrol tank.

these are ingested into the throttle body to be burnt (on low throttle) as the unburnt fumes are worse for the environment than the burnt ones.

im running BDL 70mm throttle body on DC5R with JDM intake manifold bored out to 70mm as well. Slight power gains with quicker acceleration response and alot louder with ingen!! lol

The OP didn't ask about what throttle body DC5 owners are using.
