B-SERIES T-BODY????
i was wondering what t-body is the best fit for a 94 z6 motor. when i say fit i mean, biggest bore size and still be a direct bolt on to the mani. also, my civic has a fitv under the t-body, so i assume that it will have to be compatible with that too.
any suggestions???

Re: B-SERIES T-BODY???? (mmuller)
(thanks mmuller)..if you wanted to upgrade your throttle body on a b16/pr3/obd0/all motor...what would be some good choices and what would be the performance differences?

Why is that? Can you get too much throttle response or flow too many CFMs in a car that'll see heavy driving duty? Get the biggest throttle body you can, man. Throttle response is a nice thing to have, and most stock cars suck at it.

Not if it's properly port-matched to the intake manifold.

not completely true, a properly port-matched IM/TB setup will just make sure the throttle body is flowing at its optimal rate, too large and you will get turbulence in the IM and like i said, it will hurt the flow velocity due to that

If you've got a huge throttle body and you port match it (on a slant) into the intake manifold, the venturi effect of the air volume being compressed as it enters the manifold shouldn't have any but a positive effect on performance. I understand what you're saying, and it could very well be true if you got a throttle body big enough, but for Honda applications, you really can't go wrong with something upwards of 70-80mm.

Re: B-SERIES T-BODY???? (Archidictus)
ok so lets say you get a 80mm TB, now your first issue will be that there is not enough material to remove from the intake port for you to properly port match it, next with that size TB unless you are making an excess of 400hp you will lose TONS of power on the bottom end, next issue is the fact that you are trying to cram 10lbs of **** into a 5lbs bag, the plenum size is not large enough to compensate for all that extra air in there and the runner size is definately not large enough and this is where you will get your turbulence, because there will be more air then the runners can actually fit inside them

I was assuming that, in order to port match an 80mm TB to a Honda IM, you would build a spacer specifically to slope the incoming air so that you wouldn't get that turbulance. What you're saying is absolutely correct for the examples you've raised, and I can't disagree that you raise a good point, but there are ways to make it work...albeit they are expensive and beyond the reach of most "tuners".

yeah, you would have to have an IM like the venom manifold which has proven to make no low end power at all....it actually robs the power from your low end

Re: B-SERIES T-BODY????
for a car that is all motor..too big can hurt performance i would think when your talkin about air velocity..i was wondering what the optimal size would be for all motor..i was thinkin type-r should be good,since honda most likely did some research on it..what do you peeps think?

that depends, some ITR TB's are 62mm and some are 67mm

Bigger isn't always better, even if you port match the intake manifold and the head of the b16, if not going to flow enough air to get the intake air speeds up to a level of speed you need for making horse power..... The Volume of air is important but the speed at witch if flows is just as important... Lots of Air flowing slowly does an engine not as much good as half the air flowing @ twice the speed..........It's just like an exhaust system, to big and the air flow slowly(commonly called lack of back pressure, it not pressure its just slow exhaust flow cause it's has so much room to expand)

Re: B-SERIES T-BODY???? (92 civic VX B18c)
i was jus wondering if anyone has anything to add to my ????? is the h22 a direct bolt on and what about all the sensors and the fitv, because if i am correct the obd2 cars dont have a fitv. (94 ex w/z6 motor)
