b6d=b6t

So the b6t has a festiva throttle body?

No b3 is 10 mm smaller iirc.

I have no experience with the b6t but I did swap in a b6d and I used the b3 throttle body and all the wiring that went with the b3.

Let me get a picture of those welds on the bottom of this plate, my best welding yet! - strong and sturdy.

I hope to get this wrapped up this weekend. How should the throttle body attachment be, studded x 4?

It's noticeably smoother than the factory casting. Should I take it past 60 grit rolls?

Let your finger be the judge of that.

You don't want smooth. If it's already smoother than factory leave it alone.

I have seen plenty of flow bench experiments over the years with anything from dimples to rough ground surfaces to mirror polished ports. The general consensus is that flow wise, any flow bench changes due to surface texture are within such a small margin as to not be reliably measured. For that reason, I am of the school of thought that a rough surface with plenty of fuel-vaporizing surface area is best for ports. But ultimately it doesn't matter one bit. Granted, flow bench data does not always line up with real world...But I don't think any particular surface is better enough than any other to even be worried about.

We're not talking head ports though. I smoothed everything that is not in direct contact with the fuel.
