SteveUCI took some pics at the Shinestreet meet.

Considering the hassle that Shaner had in taking off the intake manifold to get it extrude honed, I don't look forward to putting in a new gasket. If it really works, I might attempt it, as the intake maniforld really soaks up that heat; it gets quite warm very quickly after stopping the engine.

Prolene: Would the following configuration of collant hose connections be appropriate to effect a proper bypass of the TB and IAC in a safe manner?

Using marcucci's following photo

http://www.s2000.org/mods/insulator/image59.jpg

and counting hose connections from left to right on the photo, there are eight squeeze connectors showing counting left to right on the pic. The first fout clips are at the TB, and the next four clips showing are at the intake manifold.

If a hose were run from #1 clip to #4 clip, the TB would be bypassed, correct?

If a loop of hose were made connecting #5 with #6 and another loop connected #7 and #8, the IAC would be bypassed, correct?

Would 5/16" (7.93mm) hose (SAE-30R7) be the proper size? What did you use? I have attempted to take of the existing fitted hoses to verify size but so far have not been successful. Is there a trick to removing the stock hoses without damaging them?

TIA

Correct, and this is how I had my first bypass setup.

I've done this and bypassed everything on the manifold so basically it go right back into the block underneath the intake manifold.

theres a hose that carries coolant into the front of the TB just below the opening. unplug that, then on the drivers side of the intake mani there is your iac sensor, and some more plumbing. the coolant line on the bottom of this needs to be unp[lugged and connected to the line you unplugged from the fron of TB. bam, coolant bypassed. as long as you dont live in a climate that goes below 32ish you should be fine. im in south FLA so i could care less!

note, this mod is easily reversed if you need too!
