So I got the 58 mm throttle body on. "Butt Dino" says minor power increase running the same patch of road as before the mod trying to push engine the same amount. Basically I feel a small increase in power pulling 2nd and 3rd but without any real measure I dont have any scientific data to back this up. Tomorrow bumping up AFM 2 teeth and installing one step hotter plug.
Discovered in the process that I could have set the throttle body a different way and most likely got more power. The problem that I ran into is the 85-88 throttle body I have that is bored out will not work with the 93 intake and the IAC valve that is on the lower manifold. The 93 intake is missing 2 ports that would allow the IAC valve to hook up. So in my search into making it work I found out that a 5mge celica throttle body from 85-87ish is 60 mm and will bolt up with minor mods to the 93 intake manifold and completely eliminate the IAC valve.

CHEAP bored out throttle body !
It just also happens that a guy on Ebay had one for 75$ so it is on the way to my house so I can set this up with the 93 upper intake this winter. 93 upper intake 30$ + 75$ ebay throttle body = much cheaper than any company and 60 mm.
