LS3 cable throttlebody

I have an LS3 intake and need a throttlebody that is drive by cable. What will fit from OEM? Or what about the ones on E-bay? I will be using a MS3 computer. Twin turbo air to air intercooler on pump fuel. Probably 12lbs boost for starters. 80lb injectors.
Thanks for input.

No OEM options, but plenty of aftermarket ones...eBay...Holley...probably Edelbrock too...

You'll need a throttle cable bracket too. Luckily I make them! Shoot me a PM if you want one.

I read all about people having issues tuning the eBay throttle body's but I have an eBay 92mm on my ls3 intake and it works just fine. I didn't have to modify it at all to get it to idle right.
