Larger throttle body

Larger throttle body
If we run a bigger TB, can it be done with stock ECU or will you need a standalone? I've searched and found nothing on it. I'm curious as to what, if anything, needs to be done TPS wise. Basically, if you're making your own IM, you might as well run a bigger TB. What needs to happen to allow that? What works, what doesnt etc.

I wouldn't say I'm all stock. My motor is out and being torn down, head is ported and polished, doing a full valvetrain upgrade, and putting forged internals in. Then piecing together a turbo build when that's all done.
I have these brand new and never used in my shop at home.
Miller - TIG Welders - Dynasty® 350
Miller - MIG Welders - Millermatic® 350/350P
So, Just an excuse to play with toys.

No, I'll be running MS when boost comes along. I'm going to put miles on the motor before the turbo build goes in for 2 reasons. I'm a student, not made of money so to do the turbo part right, will take me a couple months after the motor is done. Also I don't like doing too much at once, too many things to go wrong and troubleshoot. That being said, the motor will run on a stock ECU for a short time. I want to know if putting a manifold on with a larger TB will be possible or not on stock ECU.

As long as all the oem sensors/valves are hooked up and operational, the air going through the tb first goes through the intake/afm. All air flowing through is measured by the afm and the engine will operate normally IMHO.

Yah, I have some experience with hondas and they respond to mods in a completely different way. Our engines are on different ends of the power band spectrum.
Now it deffinatly would be cool if you build your own manifold with a larger TB and whatnot, and It would show gains if youre going for a pretty big power setup. But to answer youre question I think it will probably run like total crap on the stock ECU. Just wait until the MS in installed, then tune for it.

And we're telling you it doesn't mean anything. Bolting a Honda head onto a BP motor (if it were possible) would probably be worth 25-30whp by itself. If the TB is the restriction, then you see power gains with a larger TB. If the head sucks (and ours is about as bad as you can get), then you might not see gains. Honda gains and BMW gains and Audi gains mean pretty much nothing when you're talking about a complex system like the intake tract of a motor.
