Throttle Body Coolant Bypass

This is perhaps one of the best modifications that you can do for basically nothing. As you'll see in the dyno below, which is of my Integra LS motor in a 92 Civic hatchback, before and after: I got back almost 10ft-lbs of torque over the entire rev range. 10ft-lbs that was present in the engine when completely cool, but once at operating temperature was no longer available. This is good for about 0.2 seconds in the quarter mile in my particular vehicle - needless to say I'm very pleased with this modification.

Above you see a diagram( i dont have the pic sorry) of how coolant normally flows through a throttle body (illustration is from an Accord). All you need to do on any vehicle is to take those two coolant lines, disconnect them from the throttle body and connect them with a coupler available in the vacuum hose section of your auto parts store. It's basically two nipples connected to each other that allow you to connect two pieces of coolant hose.

I'll go see if I can snap a couple pictures of mine when the sun comes up. I bypassed mine a couple months ago. Can't really tell much of a difference, but I gave the whole throttle body a good cleaning while I had it off and that made a huge difference and resolved some issues I was having.
