Bigger T/B worth it?

[Chi]

I think Dave is suggesting boring out the stock TB.

I would recommend a larger TB if you were doing internal work.

I had a Larger TB on a stock engine and even though it had a bit of lag at the bottom end it wasnt enough to complain about.

Top end felt much more better.

oh ok, who does t/b boring...if i do it ill only bore it out to 64mm

[bigbadbeau]

wouldnt itbs solve all of these issues? (at a price of course)

[noodleman]

itb will made the idle alot worst then bigger tb

i went from 60mm to 64mm with a 6 then 3 degree taper in to the plate...

these guys did mine in 2006 - not sure if they still do it...

He mentioned he will be using Toda Spec C cams. Yet he complains that an enlarged TB will screw with driving daily.

mate i have done alot of research and discussions with people that know they're shit when it comes to k series engines...spec c's aren't bad fot the streets, and i do the occasional drag racing...and a big T/B does stuff up drivability (im talkin >70mm)

When you had spec C's in your DC5 - what drivability issues did you experience?

[VTECMACHINE]

I just don't understand how a slightly bigger TB can screw with driveability more so than Toda Spec C's. On my DC2 with stock engine larger 70mm TB didn't screw with driveability. Low down response.. OK slightly, but improved everything throughout the rev range. I've been in a DC5R with JUN cams (which are speced inbetween Spec B and C), and stock TB, and from this experience I have made my assumption that a TB can't make drivabilitiy on the street worst than having aftermarket cams, especially Spec C's.

was it a 70mm Spoon throttle body?

if so - it is not actually a 70mm ID throttle body, and is therefore vastly different to a true 70mm ID throttle body in terms of effect on drivability.

just so you know...

I relise this... but still does it make THAT much of difference compared to Spec C cams. Can't you answer my question, rather than running in circles?

[03DC5R]

a member on here, had spec c cams in his ep3r and said it was very streetable and responsive and had torque even at low rpms...as well as numerous members on crsx

start a new thread if ya wanna know.

you are deeply off topic.

this guys does B series, but in USA...

might do K as well?

EDIT: yes, he does K series to 65mm

[03DC5R]

yeh it says that he does k as well. but he's all the way in america. i called katicore (the company that did yours) and they said they no longer do em...all good, ill just stick to stock for now...see what happens later
