Larger throttlebody on a B16A2
A few Q's:
Who makes em and how much? Which is the best in your opinion?
How much of a difference do they make?
Do they kill low end power?
Are they worth it?
Thanks

not really worth it, but it is a start to a more serious level of power. you can use edelbrock or bbk.... even if you really wanted to cheap out you could have a shop bore yours out.

if you put a larger throttle body on make sure to bore the opening of the plenum out a little too. No point in having a throttle body thats larger than the opening of the intake manifold. Most aftermarket intake manifolds usually have at least a 65mm opening.
I noticed a nice increase when i installed a bored b16 throttle body on my b16. But i did an AEBS intake manifold (with 65mm opening) and fakedata intake manifold gasket pretty much at the same time, but for a short while (couple of days) i had the 64mm t/b on the stock b16 IM and it felt better up top, don't remember a loss down low, but the AEBS IM really helped through out the whole rpm range.
64mm t/b and AEBS IM is what i suggest, cheapest option, great performance, and honda quality with the throttle body, its not sticky and it uses a FITV (lots of aftermarket throttle bodys don't use the FITV). Just make sure that if you bore the throttle body out to 64mm that you need a larger throttle plate, although a competent machine shop will be able to handle this. I beleive 4mm is the most you can bore a b-series throttle body.
I say go for it. Buy a spare b-series throttle body, get it bored, then sell ur stock one when u put the good one on, and use the money you saved (from not paying a lot for an aftermarket one) to put towards an AEBS (or other brand of choice) intake manifold.
Remember with all of those bolt-ons tuning will really bring them all together.

I put a 62mm tb onmy V6 turbo cavy (stock was 52mm tb). I ported the IM to match the 62mm tb....it seemed to make a big diff up top when the V6 was NA.
I want to make my B16 more responsive and have more power ans snap throughout the rev range especially mid-to high range.
How much does an AEBS IM go for?

from a shop here in hamilton, that i don't refer people to.
Heres a place that sells them for pretty damn cheap.

you gotta remember a v6 cavy with a 52 mm throttle body is pretty choked up. same with 2 liter VWs, those throttle bodies are super ridiculous. 60mm for a 1.6 liter engine is pretty not bad 
I mean in most cases i'd say its oversized, but the key to remember is that the engine does rev up to almost 8000 rpm which increases it's demand for air.
also, the butt dyno is not a reliable measure of power increase... my buddy put a H22 throttle body on and claimed it was super super awesome, until I proved to him that a B16 and an H22 throttle body is the same bore size. lol
anyways, like I said, it's a good start for something more serious, but the throttle body alone is not worth the money.

I won't be buying an aftermarket tb, thats for sure, way too much money. I have the knowlege and mechanical know-how to bore out a junkyard b16 tb.
I also realize, too big will hurt the motor down low which I don't want on a daily driver...
I'm assuming a 65mm is about the right size for mid to high range power without killing the bottom end grunt (or lack there of on a b16...lol).

But the dyno at DL motorsport showed that i gained a total of 6whp (just max power, a lot more through the midrange, not to mention the power carried all the way up to 8200 instead of dropping off at 7500 like with the stock IM and t/b) after the addition of the AEBS and 64mm t/b, but my engine isn't a stock b16.
If you only ever plan on doing bolt-ons then i'd skip the larger t/b b/c like bruno says 60mm is plenty for a 1.6L, but if there are other mods in store i say go for it.

that was with cromepro....but i got kicked outta there before i was really finished, they double booked me, so i had to wait for 2 hours before i could even get my car on there, then before even getting a chance to touch the cam gears he told me that i had to go.
From 3500-5000 i gained 12 ft/lbs.
At 6000rpms i gained 11whp.
I spent under $350 on the IM, t/b and gasket...so was it worth it....hell ya.
