about .5 hp on a n/a and maybe 2hp on a turbo. meaning there is no reason to do that unless you have serious hp, the stock tb is plenty big and is not a major restriction.

If it were only 2hp, I don't think that the HP extremists would even do it. I bet that it gives alot more hp being used with a standalone and a MAP sensor than with the stock AFM. But for a turbo car, it would be significantly different I would think with the above setup.
There are certain things that you have to do, its all a big balance doing mods like these. One would do it if they had a performance exhaust, a nice bridgeport, and upgraded injectors. One would not do it, or at least experience no gains really if they had a restricting exhaust, or their engine has not been ported. If you increase flow in one area, you have to increase it in all the others of the system to see a nice difference.

I doubt it's even 2hp, I bet it's even less...
I did this and didn't notice a single difference. I only noticed a small difference from doing the TB mod and removing the extra throttle plates. If you're doing the TB mod already and are bored, go ahead and shave some material off the inside of the TB. But if this is all you're going to do I'd say it's pretty worthless.

Also, the only sort of aftermarket manifolds that I've seen are the FD ones, unless you know of something else?

Using an 13B-RE or REW upper manifold/TB would be better than the stock 2nd gen manifolds for a bridgeport.

Second, making your own manifold is easy with the experienced welder, but making it effective is a completley different story. The stock ECU is designed around the manifold that came with the car. Injector direction, position and angle is critically important and cannot just be placed anywhere. How long, and how big the bore is on the manifold piping is also critical.
Just curious though, do you know of any aftermarket TB's that can mount the RX7 TPS ? I looked around but didn't find much, my biggest concern was trying to see if the TPS sensor would fit.

Second, s5 n/a manifolds are worse with a ported motor, even streetport, than the s4 because the VDI doesn't work as efficiently when ported.
Third, of course you would pay someone that knows what they are doing to make you one.
Forth, why are you talking about a stock ECU? Why would ANYONE with a bridgeport EVER run a stock ECU? The stock ECU argument has no merit when talking about a bridge because it should never be used.
Fifth, if you are going bridge you want standalone or carb, if you have standalone you can use any TPS you want.
And you can use weber IDA's with a fuel injection application, just will have to set it up properly. What do you think peripheral port motors use? Do you expect those to run with the stock manifolds too?

Well you talked about making your own manifolds, and I simply stated that its not easy, now your saying that you would of course hire someone to make them for you?
A standalone is big $, we're not all rich. There are members on here running bridgeports with the stock ECU cause they have the skills to bridge, but not the $ to spend on a haltech.
Paying someone to make the manifolds would be way to much $, it would be alot cheaper just to go turbo I think.
Just becuase you don't agree with me doesn't mean you have to be a ***** about this. Your last line there
"what do you think peripheral port motors use? do you expect those to run with the stock manifolds too?"
You don't have to try and make me look like a ******* idiot, I know what a peripheral port is, and its impossible to use any stock manifolds, second or third gen, with that, they must be custom fabbed.

I'm sorry if I came across as a *****, but the information you're giving isn't completely educated, sorry.
By saying "making your own" I didn't mean the person would actually do it themself, of course they would get someone else too. It's not as expensive as you'd think, it doesn't have to look pretty. I've talked to Sonicrat about custom manifolds he's made/had someone make for the supercharger setups he does, and it's really not all that bad from the way he talks. Plus he explained how to do it a couple times on here.
Name one person on here that is running a bridgeport without standalone or carb, please I would like to know so I can ask how they did it.
You have to get off the money factor here, if you're going bridge you should have the money to do it right, otherwise it's not worth it.
This has gotten way off topic here and gone into a discussion about bridgeports rather than ported throttle bodies, but I think it is good discussion anyways.

True. Sorry bro I'm hear to learn, and yea I got a ways to go. I can totally except the fact of being corrected, and your right, if your gonna bridge then you might as well do it right with a good amount of $
sorry bout that.
sorry bout that.

^^ a ***** maybe but all good information comes at cost. The reply needed to be made at whatever cost, even if your reputation grows slightly more (but your *****..ness won't)

No worries.
Back to ported TB discussion I suppose
I know that an engine builder (BDC) does an interesting port on TB's for a cost. IF you're going to port a TB I'd do it like he does, it is probably the best you can get while not removing too much material. However he charges a nice fee to do it (looks killer though )
In my case I didn't do it like him (time constraints), and mostly just removed a bunch of material and slapped it back in. Would've redone it but I'm going with S5 TII LIM, FD UIM, and FD TB soon. Most likely I'll merely "clean up" the FD TB which I think is all that is worth anything. I doubt many people will see very much of a gain from TB porting.

I will! I didn't spend hours though, maybe a half hour max but I wasn't trying extremely hard to make it perfect, had to get it done and back in my car.

Here my thoughts... after installing my TB which was Ported, 2nd Butterflies removed w/ thermowax, and the coolant bypass mod. I could definately feel a difference. not a huge one, but for sure i could FEEL the difference in acceleration. I'm sure alot is due to the 2nd butterflies removed, but under boost it felt great. Though cold starts are still a pain. oh well..

Can One Remove The Extra Butterfly On A 90 13b, Im Assumming That It Has The Extra Fly On It? And If I Did That What Am I Looking At , As Far As Performance, Or Should I Just Leave The Dam Thing Alone , Lol
