beautiful write! I've been looking for a way to modify my tb for that better flow. Was thinking off just going straight to a new J's racing 70mm TB at one stage haha.

haha yeah lol
Yeah this DIY works really well.
Cheers!
when i first read this article i put it in the 'too hard' basket - but now i think im going to buy a dremel and give it ago
ps Beeza - that muffler i bought from you is still going strong but i think its at the end of its days lol
Oh true,at least it was cheap then! :)
U don't need a dremel Saint,just a half round file!
Yeah if U can get a spare TB,that would be best.
Have to calibrate the TPS too..it's not hard though,if U just keep reading the DIY's,they sink in.
I gots a spare y4 one :)

do they have to be calibrated per car or are they much the same?
wanna sell me one thats calibrated and port/polished? lol
U can calibrate the tps on any car cause it's the TB opening and closing that it's measuring.
Then U would just bolt it on and adjust the accelerator cable,then check the idleing,adjust it via the idle/air screw,then reset the ecu!
hello, will this have any effect on a dc5 type s integra tb?
Definately.Will work on all tb's!
just finished doing this on a D16y1 TB and installed it onto D15b7
used a dremel for most of the work
im getting idle hunt now - only a little - not as bad as when u unplug a vac line
trying to trouble shoot it - i may have to put a spare butterfly in that is unmodified and see if it makes a difference
TESTING REPORT
ok so at first i was getting hunting idle - i went back over all bolts, screws, nuts, seals etc without taking the TB off the car and it dramatically reduced
but occasionally it will still hunt a couple of times at a stop sign or lights etc than flatten out
i have noticed that the idle isnt constant now either - its slowly waves up and down - but almost not noticable
the TPS voltage adjustment has made a huge difference - the acc pedal has alot more control and response in it now
its alot easier to control the speed of the car without having to go up and down gears rapidly
im not too sure how much difference the PnP has made...
things i have noticed are that i have heeps more bottom end - like alot more torque and response down low
but i feel like theres a slight loss just above midrange and than it gets going again towards the top end
it is a tad louder now as well
overall i think its an improvement
when i get time ill be finishing the PnP on the D15b7 intake manifold and the D15b7 throttlebody i just took off the car
i also have a D16y1 intake manifold to do and eventually i will do the D16z6 intake manifold that is on my car as well
currently rebuilding a D16y1 head to mini-me onto the D15b7 block with a y8 headgasket
i wont go too far into it - u can read up on it in my build thread
there are also pics of my TB + PnP work in my build thread =)
Awesome awesome Saint.
They are sensitive things bu U have already reduced it a lot,so I'm sure U will reduce it more in time and learn more in the process.
The main thing is getting the butterfly plate to seal properly OR mine has a slight gap at the top which lets air in and with the idle/air screw closed,that's how my car idles.
Just gotta make sure the spring on the tb has good torque in it i.e. the butterfly plate springs shut firm.(The tb should be hard to hold open with your hand after a short time..)
Always good to reset the ecu regualary/after playing It helps to smoothen everything out after making changes.
Keep us updated mate!
great work and great write up mate!!!
but dont think that worth the hard work since the internal diameter thru the TB disc is still the same
so the air flow rate stay same unless the internal diameter is enlarged all the way...
considering spending a whole afternoon filing it i rather wax my car lol
