the water travels from the back of the manifold just under the #1 intake port, to the IAC, then from the IAC, to the tb, then from the tb, to the metal return tube that travels from the heater core, to the water pump, behind the turbo manifold ... (the L shaped metal tube that runs from the tranny side, allong the block/head split to the water pump)... all you need to do is replace the two smaller hoses from the IAC to the TB and from the TB to the return tube..
(L shaped tube) with a longer hose directly from the IAC to the return tube. bypassing the TB completely... both bungs on the TB are on the bottom about 1.5 inches from one another... thares no need to cap off the tb becuase thare is no passage to anything else inside the TB.. its just a hollow chamber for water to pool before returning... its a very simple mod that really dosent make much of a difference .. the car will actually take a bit longer to warm up in the winter...but in AZ you really dont have to worry about that do you??? all it does is help the engine to warm up faster to get it to operating temp faster to help with emissions..
water flows through the intake mani anyways
in two places so it heats it up no matter what.. this will just keep your TB a bit cooler in the summer when its hot outside....
