Everyone, that is what FieroGuru considers "whipped up". Seriously.

Looks awesome man.

The more I looked at and reviewed the shifter bracket, the more I just wasn't liking it much, so I decided to redo it.

Here are some pics of what the new one is starting to look like. I just need to finish the final shaping and tack weld it before the next test fit:

Tacked the 2 shifter pieces together:


Started knocking out a lot of little things to finish the accessory drive. I turned some aluminum spacers to replace the washers used for mockup on the A/C bracket:



Also counter bored the bottom AC compressor hole so it will clear the belt:


Trimmed off the top hole on the AC bracket so it would only have 4 holes like the engine bracket:


Then I fabbed up the rear support for the AC compressor:



Moving on to the Alternator bracket, I made some aluminum spacers to replace the washers:


Fabbed up the backside support bracket:



Fabbed up a spacer sleeve for the tensioner to properly align the pulley on the tensioner:


Found a spacer the right thickness for the idler pulley as well (I will pick up a new idler when I pick up the new belt):


Mocked up the accessory drive to get the needed belt length:

What cables does this transmission use?

This car was used for the Getrag F23 tutorial: http://www.fiero.nl/forum/Forum1/HTML/087296.html
That thread states the car uses a stock Getrag Select cable and a custom length cable for the shift cable.

I am a stickler for detail and think the statement that it uses a stock Getrag select cable is somewhat misleading. The only reason the select cable works in this Fiero is because it is of the adjustable aftermarket style. The stock OEM getrag select cable as well as the cables from Rodney Dickman are non-adjustable and will not work with this bracket setup.

Here is a picture of a Rodney Dickman Getrag Select cable (top cable) side by side the one that is in this car. Notice in the fully retracted state, the distance from the mounting boss and the ball ends are significantly different, and you can see quite a bit of the adjustment has been used to make the sleeve of the cable longer.

I would classify this as a modified sleeve length getrag select cable.

I already have my car setup with stock select cables and saw you broke yours and was wondering if this car had a stronger solution. It shifts nice but I'm afraid to jam the gears. I also noticed that even with my adjustable pushrod as short as it goes I'm having an over travel issue where the clutch reengages. I'm wondering if this is a spec clutch issue or an f23 issue. Easy fix either way I suppose. Great build though, it one of the few threads I look forward to when I see updates.

The cable issue on my F40 swap is due to using the thinner select cable for the shift cable. The forces the shift cable sees are just too high for the select cable. This F23 swap has a legitimate shift cable for the shift functions, so it should be OK.

The overextension issue is likely a mismatch between the HTOB travel, the design of the pressure place fingers, and the clutch disk or a combination there of.

Knocking out several little odds and ends as I get ready for another test fit.

Installed the heater supply AN fitting and hose end:


Installed the AN fittings for the water pump as well and took a picture of the accessory side nearly done (except belt and paint):


Installed the MAP sensor to the upper plenum. It is on the front side of the plenum, so you won't see it, but it still is easy to get to for future replacement:


Tweaked the throttle body TPS lever so it would engage the sensor lever. Here is a before pic:


After:


Installed a 180 degree thermostat:


Plugged the vent line hole in the thermostat housing:


Thought about the PCV routing and ended up flipping the valve covers side to side so the PCV can be on the rear one (along with the oil fill) and the front one is for the clean/metered air inlet. The rear side I used a brass compression fitting on the underside of the intake and then bent up a hard line that connects to the PCV valve with some head shrink (not shown). The front side I made a housing for another compression fitting, then bent up a hard line to the throttle body where more heat shrink will be used to seal the throttle body end. These hard lines will be painted black before final assembly.

Here is the rear PCV line:



Here is the front PCV line:


Started routing the plug wires. Every plug end has a DEI boot protector sleeve to keep header temps from causing damage. The coils boots are not installed as I like to mock the wires up and take some time to look at them before locking into the final routing. But I think this routing has promise.




I straightened the oil dipstick, removed the mangled bracket, and then reshaped it for a decent route past everything. I still need to cut it down (way too tall) and make a new hold down bracket.


I am hoping to do another test fit some time this week to verify the shifter bracket, work on water pump placement and hose routing, fab up the throttle cable bracket, fab up the cold air intake, and do some pondering on the exhaust.

That looks awesome! Thank you for the update.

It looks awesome but I have to laugh. I keep seeing pics of this wonderful beast of an engine and there, tucked away under it is the same tired ol' crummy a/c compressor without so much as a lick of paint to make it look 'nice'.
Truly fabulous work though.

------------------
Anything I might say is probably worth what you paid for it, so treat it accordingly!
