In case anyone is wondering what the 2 blue tubes are, they are PVC tubing that holds 2/0 welding cable to the battery which is located in the front.





Of your heater tubes in this photo, is the bigger tube on the left or right? I don't think I can tell reliably from this photo.

Will,

A photo is worth a thousand words.....

The larger hose is on the left facing forward.

Thanks! I was trying a set of '85-'86 heater tubes for my '87, but didn't have the positions documented

I was finally able to get the old engine/transmission out of my way so I could clean up the engine bay.

In the process of cleaning the engine bay area; have removed all the vacuum lines and tubing that will not be needed or used for the 3.5 v6/4T65e install.

Also, I have ordered additional 6AN fittings to re-pipe the Fuel delivery system. I will be adding a fuel pressure sensor in the system.

I have installed but not yet wired the new Power Distribution-Fuse block for the 3.5 install:




I have ordered 1 coil over 7" sleeve to check for fit. Making sure that the sleeve will fit the KYB struts before I commit. So, once again I am waiting on parts in order to move forward.

I have re-piped the fuel delivery system, adding a fuel pressure sensor.



I have received the coil over sleeve however, I have returned it due to the fact it would no slip over the strut. It's pretty difficult to fit a 1.95" ID sleeve over a 2" OD strut. Another coil over sleeve has been ordered.

I am also in the process of building the passenger side CV axle. What a nerve racking experience. Again, waiting on crimping tools for the booths.

Man, just read this thread from the start... I've been away from PFF for far too long.

Thanks for the great read and excellent work.

Yes, I am still at it....these dog days have slowed down the work with the shop temperature hoovering around 100 plus degrees.

Of late I have been attempting to build CV axles for the build. Lots of information on how to build and what to use. However, all have failed to indicate that one needs some specialty tools and materials for the job. Tools like banding tool, CV booth installation cone, etc.




Currently working on the passenger side CV axle. Again, waiting on an inner CV booth. I found out the hard way that the inner booth on a manual Fiero CV axle is not the same size as the inner CV booth for a 4T65e transmission. Oh well....




I have also ordered from Rock Auto a driver side CV axle for a 2004 minivan for the driver side.

In addition, I have removed the Fiero heater hoses in the engine bay for the new install. Also removed have of the heater hose setup on the 2010 3.5 v6 so I can pipe up to the Fiero heater hoses on the firewall of the engine bay.


For whatever reason I could not get Google Photos to update my photo album so photos of the progress will have to wait.

The CV booth has arrived for the passenger side CV axle build. Hopefully I will that that accomplished today.



Also, the driver side CV axle arrived. Looks like I will be tearing that one down and building another CV axel? I have ordered another Fiero driver side Manuel CV axle from RockAuto for the build.

In addition, I have ordered 5/8" 90-degree barbed couplings and the necessary hose clamps to pipe up the heater hoses for the conversion.
