I am pretty sure he just pressed the outer races from the new housing (they are removable, not part of the machined housing like the 88 fiero is). You can see this step profile in the rectangular bearing housing in this picture, which shows that the original races were removed.


I think all Bubba did was do some minor machining inside the fiero housing (enlarge it a couple of thousands and machine the old curved bearing surface to a 90 degree corner to accept the bearing setup from the rectangular bearing housing). His desk is probably like mine with lots of boxes and parts from multiple projects on there at any given point. So just because there are bearing boxes on the desk doesn't necessarily mean they were used for this bearing mod.

If all else fails, measure the ID of the housing and the OD of the flange setup and find something that is close in the Timken manual.

Here is some info on the bearings that bubbajoexxx shared with me back in 2010 via private message:

quote bubbajoexxx:all of the good 51309 bearings are bolt together units that use 2 single tappered bearings as any wheel stub would use whitch make for a reliable unit

quote bubbajoexxx:the bearing im using are the bearings that come with the hubs to start with as well as the seals they are koyo usa num.LM67048 and race is LM67010 and the stub is made to use this bearing with a pre load of 20 inch pounds on the nut

Thanks Racerx11 that was the set of bearings I came up with had appeared to be exacly the right size took me 2 days to figure this out and I was hoping bubbajoe would help and clear this up. Again Thank you so much.

sorry guy havenot checked the tread for a while if i had i would have got back to you

Happy New Year everyone.
Got around to Re/Re of the windshield to install the windshield trim I wanted that wraps around the glass edge.
It's a little wider than the stock molding and covers the roof panel edge nicely.
When the glass was originally installed I had a temp T molding knowing I was removing all the body panels for paint.

Here are the photos:










My thanks to Rick and Larry at Speedy Glass Welland who did a nice job just like we did on the rear window.

Thought it wouId be a good idea to document my RPO codes for future reference.
My Indy is #1620 of the 2001 produced and one of 160 for the Canadian market (notice the French on the label).
Y82 is the Indy pace car replica package, but when I have time I'll look up the rest of the build sheet codes to see exactly what it came with...

Here's the RPO codes I could decipher - missing a few though.
If you know what they are please advise.

Thanks guys, positive ratings given.
Just B83 left to find...

Found this ... maybe the one ..

Spent my Christmas Fiero gift money on a billet Aluminum dress up mount for the Optima Yellow Top:





It fits in the right rear battery tray nicely:

Nice bling with the cover...

Since the console is not connected, I would consider matching the woofer box to the insert behind the seats.

Either way, the box looks good.

Bob

Have you considered going wide body?



Thought I would Hatch it for yah

the car is already 4 inches wider than stock read trough the tread and you will see how it was done

Another minor winter project I'm working on is porting the intake manifolds to match the heads.
Here are the disassembly pics:

Progress made on the intake porting:









This is step one using carbide bit and drill.
Step two will be with a stone bit.
Step three will be sanding/honing.

Looks good...

I wouldn't bother with the stone. It will just gum up quickly. The sanding rolls will smooth it out nicely. Also, a little roughness breaks up the flow and actually increase flow. Keeps the air from "sticking" to the walls. At least that's how I remember it when porting my TPI intake, plenum, and runners way back when...

Bob

Is there an engineering concensus regarding surface roughness to obtain optimum turbulence? I think it might vary depending on the different flow velocities at different engine speeds.

David, I'm sure there is, and it would make sense about the velocities, but IIRC, you want the intake roughed up a bit (not a lot), and the exaust as smooth as can be.

Bob

Wet flow needs a little roughness to make the boundary layer thicker and keep the fuel entrained in the main portion of the flow.
Dry flow should be as smooth as possible to keep the boundary layer thin and keep the effective area of the port as large as possible.

Are you doing anything about the sharp change from the vertical "manifold" to the angled port?

I wonder if there's an RA surface value to quantify the roughness being discussed. Should airplanes have golf ball skin?

Golf balls need golf ball skin because the sphere is actually aerodynamically lousy... The golf ball skin thickens up the boundary layer and causes it to stretch out behind the ball, essentially becoming an airfoil.

quote Originally posted by Will: Are you doing anything about the sharp change from the vertical "manifold" to the angled port?

Hi Will,
Yes as you know firsthand, the cylinder head has angled ports (with a textured not smooth walls btw).
A cross ram design would have removed the sharp angle change but it would have been too tall a setup for my application.

Here's my progress to date:

Indy Northstar-Stretch

hey Joe,


I sent you a message, can you check your pms.

Thanks

This weekend I finished up my custom sub box with the charcoal gray carpet ordered to match the firewall:









I'm pleased with the finished product.

I weighted the completed sub box and it came in at 15lbs with sub (500W 8" speaker is 6lbs 7oz.)
Before installing the sub I used Hush Mat to seal up wire holes and reduce firewall heat behind the speaker location.







Once wired up the box snuggly velcro's in position between the seats:

Nicely done. Always amazes me how almost everything on this car is a one-off custom piece.

quote Originally posted by Fiero2m8: Later I'll try polishing the stainless to see how nice they can look, but most importantly I'm eliminating potential rust in plain view of admirers.

Better take care of the rust on your CV joints, then

Ok, the intake system is back on the car and I've been able to drive my Fiero this weekend.

The intake manifolds were prepped for reinstallation:


I cut my own gaskets this time:


After dressing the gaskets with RTV, I used the torque wrench to bolt them on and left them 24 hours to cure:


Then I installed new base gaskets and installed the carbs changing any rusty nuts and bolts to stainless hardware as I went:


Next I adjusted the linkage to ensure no binding and that springs snap linkage back to throttle stops:


Then it was a matter of cleaning air filters, adjusting air mixture screws and unisync the 8 carbs to 5.5 airflow.
I tried leaner main jets that eliminated black smoke at full throttle and used the air compressor to blow out the idle jet circuit of the whistling carb.
Lastly I lowered the fuel pressure from 4.5 to 3.5 PSI and tweeked the timing.


Now I can drive it as reward for each time I work on it...

Looks real good, Ryan.

Thanks Bob.
I've placed an order from CB Performance to stock up on main, idle and pump jet sizes now that I'm done experimenting with drilling jets.
My current DRLA40 drilled setup is currently approx 60 idle, 145 main, 190 air corrector and 35 pump jet.
This way I will have several extra sizes to trial and error for a test and tune session on my engine builder's chassis dyno.


4- 7348 Jet Doctor Kit - fits 36, 40, 45, & 48mm DRLA Carburetors (one carb)

4- 7211 Dellorto Pump Jet for DRLA and DHLA Dellorto Carbs (specify size) - .40

8- 7210 Dellorto Idle Jet for DRLA and DHLA Dellorto Carbs (specify size) - .60
8- 7210 Dellorto Idle Jet for DRLA and DHLA Dellorto Carbs (specify size) - .62
8- 7210 Dellorto Idle Jet for DRLA and DHLA Dellorto Carbs (specify size) - .65

8- 7209 Dellorto Main Jet for DRLA and DHLA Dellorto Carbs (specify size) - 1.40
8- 7209 Dellorto Main Jet for DRLA and DHLA Dellorto Carbs (specify size) - 1.42
8- 7209 Dellorto Main Jet for DRLA and DHLA Dellorto Carbs (specify size) - 1.45
8- 7209 Dellorto Main Jet for DRLA and DHLA Dellorto Carbs (specify size) - 1.48

I also have unmolested 150 / 160 mains jets and 180 / 205 air correctors at my disposal as well.

There are those that prefer to paint a Fiero with the panels off the car, while others just repaint with them installed.
A couple weeks ago I decided to be "that guy" that does both (Phase 1 panels off, Phase 2 panels on).
With the amount of custom body mods on the newest project, I decided to redo some blemish areas that weren't at my expectation of "show" quality.
The remaining oil based Shadow Mica will likely be used up in order to address these but I'm optimistic the extra work will be worth it

Here are the pics after body finish work and sanding.

Hood, front bumper cover and apron getting additional TLC:


The rear bumper cover got attention where holes had previously been drilled:


Scratches on the roof, cracks at the hatch hinge and chips on the door panel invited them to the party as well.
Front fenders were fine but didn't want any paint match issues so they are prepped too:


Next it will be masked and painted in the booth.

Indy Northstar-Stretch

I polished and waxed the new paint job in time for the Explore Niagara Cally Rally.
This was our third year participating and first with Fiero2m8.
Out of 27 cars, this was our best result:

Well I wasn't so happy with my 4 wheel alignment when the front upper control arm moved under braking!
Bolts weren't tight enough and it moved in the cross member slot to adjust camber.
Sometimes you have to do things yourself or at least check the work of others...

Anyways did get a nice drive in through Port Dalhousie, Niagara-on-the-lake and the falls on holiday monday (Victoria Day).

I installed the jet doctor kit for my dellortos which are like snorkels for the idle jet air inlets.
This minimizes the chances of plugging the idle jets with dirt.
The existing holes are plugged on the top of the carbs:



The new jets are ready for dyno tuning but in the meantime I've jetted to dellortos factory settings:
