Jdm dc2r, boring out throttle body

[Kiz_EG6]

not by the "Wakefield" in his sig

just make some butterflys up with a pair of tin snips

Yeah, real good seal that'll make! car will probably idle a 2.5k!!

Just cos he's taken his car to wakefield, doesn't mean he is interstate!!

Ok i get the point, it was just an offer, i have a hub dyno at my disposal for a small time, just thought i'd ask the question, i wasn't going to search threads for his location

That's all well and good, but how you going to make a new butterfly?!?

So you in Vic or not?

Im going to try for a tapperd bore outter and maybe port match on manifold side...

retain std butterfly with std surface area at butterfly..

think spoon has it similar..

Do you think it'll have the same effect as a full bore, or are you trying to get a ram like effect?

might sound stupid:
I guess the tappered bore must work by design as spoon utilises it.. at the very least it should not make things worst.

only reason i am completing a taper bore is b/c i would hate it if i lost the honda idle.. and I also dont want to replace the butterfly


I will still need to do abit more research on the topic.. I think totti has something similiar... havent really spoken to him to find out its benefits

Yes but spoon would be using it on an internally worked engine!
I am still sticking to my original sentiments, as i believe that a larger T.B can give you a pickup in performance on a stock engine, though i do not beieve that a tapered bore would!

LOL!

please see post #2 and #3 in this thread.

a tapered bore is what yellow-dc2 started randomly talking about initially, which is quite ironic i guess? this thread has come full circle!

i did my TB to 63mm and had the butterfly plate replaced,

my idle is fine, and have no problems at all...

Down i go... so the whole argument we have had our wires crossed
So tell me, you thought i was talking bout a tapered bore the whole time?

Also, as you stated tink, if you get a proper new butterfly with a good seal, the idle will not be an issue
