no but u can google it more than likely
but i know for a fact u can put a BSeries T/B on a Dseries
not sure if D fits on B tho... should but why when its smaller

Putting that throttle body on your motor will DECREASE your power.
The reason is that the intake manifold isn't port matched. Without the IM being bored to the same size more air will come through the throttle body and hit a bottle neck when the IM intake port is smaller. This will create turbulence in the intake port of the intake manifold and the throttle body which will decrease your air flow.
With your airflow decreased you will lose power. A larger throttle body only works if your intake manifold is port matched or bored larger.

x2. Only way to make it work appropriately.
Though if your motor is stock, the only thing you'll notice is a little increase in throttle response.

and NOT ALL B-SERIES TB's work. there are certain one's that will, i really am not sure but i think a b16's will work as well as b18b and b18c5, dont quote me on those.
p.s. please search before you post.

He won't even notice that, the increased turbulence will slow air flow through the intake port so it'll lower the power at top end slightly. If it was port matched it would help a bit on throttle response, you're right, but nothing really noticeable power wise on a SOHC.

What mods? If it's stock, leave the stock one.
Yes, you can make it too big.

Sizes in millimeters.
Unless you really know what you're doing, do NOT port your own manifold. If you change the sizes on the runners enough (which is quite possible), some cylinders can run leaner. This, in turn, can make it run hotter. If you couldn't put it together yet, this is bad.
Save it for the professionals.
Edit: It's sort of unclear what I said. I don't mean how much you change the size from the original state, I mean variations in the size in between the runners. For example, runner 1 might be much bigger than runner 3.

If you have it professionally port matched then sure, you'll notice a tab bit more throttle response, but for the money you'll spend you could start piecing together a turbo.

Re: B series throttle body on a D series motor (ALLMOTOR EK)
i got a vx d15b... would a d16z6 throttle body fit?
my vx throttle body is hella small and i want to put an intake on but nobody makes it for vx so i was thinking if it was possible to swap over for the d16z6. will i lose any power?

Yeah, if you're gonna slap the throttle body on, even if it's not the proper way, take a dremel bit and widen the port a bit on the intake manifold. Bigger TB w/ regular intake manifold intake port = slower air flow due to turbulence.

PS - do this off the car so you can clean the 900 million metal shavings out of your manifold before you start the car and foul your oil and ruin your motor

I was just reading about this, and what the guys above are telling you is correct:
"Over-sized throttle-bodies offer a larger diameter opening and flow more air. Is this a restriction in the system? If your engine... won't flow anymore air, then the larger throttle body can't help. In fact, it may hurt off-idle performance. Once you do make changes to allow the engine to flow more air, it can help make more power. Keep in mind, when you improve airflow, you must also calibrate the fuel flow to match, or you're not going to make more power."
