How would i do this on a 94 z28 I need a description to be very specific i really dont have much free time with baseball. Thank you very much.

 

Here is a good walkthrough (I found it on Google, thanks to the owner):

There are 2 coolant lines that run into the throttle body. One line runs from the radiator/front of car area to the drivers side. One runs along the intake manifold, is actually a metal pipe, then turns to rubber hose before it connects to the throttle body on the passenger side. It is the lowest hose on the throttle body if you look at the passenger side of it. The hose on the driver's side is at an equal level with the one on the passengers side... You take the hoses off of the throttle body, and connect them together in some way shape or form. I used a hose connector from AutoZone (plastic piece that you slide the hoses over and ziptied the hoses to the connector). I didnt drain the coolant level, or block off the pipes from the throttle body (didnt see a point in it, other than cosmetic). Hope that helps.

edit: got beat to the post by a couple seconds

 

Disconnect the two hoses located at the bottom of the TB, take a compatible sized metal pipe and attach the hoses to it and you got it.

 

thanks essential wut does this do

 

It keeps hot coolant from running through the throttle body. Supposedly the hot coolant heats up the air going into the motor, and you dont want the air to be hot, because hot air is less dense than cooler air, meaning less air will move in than if the air wasnt heated. Removing the coolant lines to the throttle body eliminates the heating of the air in the TB. I saw it gained a consistant 3-5 rwhp on a dyno on another site, dont remember the link though. Ill post it if I can think of it.
