13B-RE UIM to S5 LIM Adaptor (Pics)
Just bought all of this for $200. I think I got a good deal. I did a search and did not find any of these to compare with. It looks like it should work just fine though.
I really only bought it cause I think when polished they look great. Now if I can actually improve performance just even a little bit, that is just a plus
I started polishing the elbow today, but still have a long way to go. The UIM will be sent to be chromed.
From what I read, it's better to use it with a 20B throttle body. But How do I tell the difference between TB's?

oh yea
finally someone is doing this
i was looking for people do the same thing for a while
i remember the easiest way is use the gasket to do the port matching
um...

SO an overbored FD TB would be the same if not bigger (depending on the bore) of a 20B. Because lets face it, were not gonna find 20B's at the local pick and pull, and we need all the options we can get.

Well I tried to finish the polishing, but that **** is a pain in the ***. It's not as easy as I thought, so I'm taking it to a Pro.
You're right!!!
To find a 20B TB will be a pain in the ***, so I'm not even going to worry about it. Plenty of cars get to 400hp just with the S4-S5 UIM.

I don't get this mod...
Any flow gains you might get from the RE UIM, you would loose in the funky directional shift in the intake runners where the adapter fits.
What is the advantage of this???

I have a 20b tb for sale.
The funky bends in the adapter are hardly bends and they are only really at the primary runners. The secondary runners almost line up so the angle is very slight. Even with that, I'm sure it still flows better, but without flow testing, we'll never know.
The larger tb openings from the rew is the main reason, but I did mine more for the bling factor

there are radical angles there, that would seriously compromise the runner velocity.
Perhaps in person it is different, but looking at that picture, I would say that you would loose torque and power from about 5000 RPM and up.

You're right, the angles in that pic look huge, not to mention the holes in that adapter plate don't look round either. It's still nowhere near the angle that the airflow makes with the TII uim. That looks like a homemade adapter of subpar quality (no offense meant). I was thinking of my adapter and what it looked like. I used a cnc'd adapter on mine because I was a little worried about all the material you had to take out without an adapter leaving the runner walls very thin. I also used a 13brew mani which could have different runner positions than the cosmo mani, but I do not know. Also, as the height of the adapter increases, the angle between the runners decrease, though mine looks about as thick as the one pictured above.
