Corvairs had metal temp sensors in their cylinder heads. Maybe one of those could be used in that bung (as long as the EGR is not connected). With the 3 wire temp sensor in the cylinder head, all we need to fully interface with the Fiero chassis is a coolant temp switch, however.

Intake manifold removal is only required on the early metal box intakes. The later composite manifolds introduce the EGR gasses through a TB spacer. They don't clog NEARLY as much as the early ones do.

I will either get the 3 wire temp sensor or add a fitting to either the surge line or the hot water outlet line to the heater core for the Fiero temp sensor.
I made a slight error in setting up the egr. I put the egr bung on the forward bank exhaust after the cat which may not be such a "hot" idea.... I am guessing that the higher temp of the exhaust gas plus the different chemistry of the gas may make it unusable for egr purposes.[This message has been edited by cptsnoopy (edited 06-11-2008).]

After the cat? It ought to be cooler then.
The only requirement on EGR gas is that it be inert.

I don't know much about how the cat works but I am under the impression that the cat actually increases the exhaust temp through the chemistry reaction taking place. The warnings in the car manuals about not parking in an area where vegetation or other combustibles are present near the cat gave me this idea.

I think this will work for the Fiero temp gauge sender. This is the hot water outlet from the water-log to the heater.

Hi Charlie,
What do you plan on using for a throttle cable? For some reason I thought the '84 cable (4 cyl) would work, but I'm finding it's not that close. FWIW, it worked with the 3800SC. Justr one more piece to the puzzle.

I used an '88 4 Cyl cable with slight mods to the bracket on the throttle body. I might have a pic.

Sorry it took so long to reply. I have not hooked up or looked at how my throttle cable will work. My guess is that Russ already has it set up so I can just attach my throttle cable (88 4 cylinder) and be good to go.
I did get a little more of the plumbing done. The 3/4" heater return line is run from under the belly pan of the car up and along the fire wall and connected to the upper 7/8" port of the surge tank. I just need to get more hose clamps and tighten it all up. I don't quite like the way I ran the 5/8" brass fittings for the heater line coming off the engine so I will get some more aluminum tubing and bend up another piece. I hope to use a rubber 90 on the passenger side near the frame rail to complete the connection. It will need enough room to flex for engine movement. Then the 3/8" surge line to the upper part of the surge tank (should be a fairly short run) needs to be connected and I will then be left with the wiring to do.

yup. the 88 4 cyl cable should clip right into place like it was made for it. errrr.. it was actually
