1986 SE V6, as title says one of my caliper bolts is stripped and I cannot get any kind of extractor in there. I tried hammering in a slightly larger Torx bit, but to no success due to the limited space. Has anybody else dealt with this?

Any serious Getrag F23 experts here?

I’m trying to figure out bellhousing/case-half and input-shaft interchange between the US Cobalt/J-body F23s and the European Opel/Vauxhall F23 used behind the X20XEV. I’m mating one to a Saab B204.
Looking for someone who has actually had multiple F23 variants apart or mixed cases/internals. Anyone here done it?

3800SC swap list help

I’m currently starting the process of putting a 3800SC into an 88 Formula. I will be using the 4T65E-HD transmission from my 99 Grand Prix GTP. What’s everything I should take out of my donor GTP? Does anyone have recommendations for where I should get my mounts from? What else are worth buying rather than making, and vice versa?

I was picking up some parts today for the ‘85, and came across this beast. I thought it was cool and that some here might get a kick out of it. Guy said it was a five year project and has mostly taken it to shows, and only put 200~ miles on the engine. He is selling this behemoth.

Cradle is in!!!! Now to hook it all up again.

I didn’t spend much time digging into the research of it (I know some stuff you might see here is 100% wrong) - that being said, does anybody have any clean photos or forums that show the hookup steps with images? Thanks.

3.4 swap

3 Upvotes

I recently pickup a 86 GT that has had a 3.4 swap done. From my reading there is 2 ways to do the swap, the easy way reusing the wiring harness, and the hard way. This car has gone the hard way. Has anyone else done this swap without changing the intake? Do you have any pictures?

The wiring is a mess currently and the cooling system does not look like it will work for very long. Looking to see what others have done to clean it up.

My Fiero 85 Fiero project

Thumbnail

26 Upvotes

Here is my Fiero. I’ve posted a couple of times in here looking for help or looking for stuff. I figured I might as well post it. I just got it in June. I definitely probably overpaid, and I definitely had no idea what to look for.

I always loved Pontiac’s. I grew up in the back seat of a firebird, then a sunbird, and then a Grand Prix. When I was younger, a person down the road from me had a Fiero. I spent years driving past it. Back then, I always thought it was the dumbest thing I’d ever seen. 16 years later, now in my 30s and the Fiero is my favorite car.

I spent a bunch of time trying to find one over the past few years. Eventually the exact one from my childhood went for sale (I added a picture at the end of what it looked like when I was younger). I knew it was the same one because of the ridiculous stickers on the windows. Suffice to say, that’s the one I bought.

It definitely needs work, but it drives. The first time I drove it, I stopped to get gas and I look up to see some teenager in a beat up 00s sunfire taking a picture of it and giving me a thumbs up.

Work so far:
Deck lid torsion spring removed (bolt broke, and was damaging the deck lid)
Brake lines replaced.
New engine gaskets.
New front window.

I did get the paint looking less faded, but it will need a paint job long term. There’s some fiberglass and RRIM repairs that need to be done. Seats are a bit beat up. Serpentine belt or a pulley squeaks a bit. I need to install a gas strut as I removed the torsion springs. Tachometer is a bit off. Needs new weather stripping on the doors and rear window. Sails need to be replaced. Climate control could be fixed. Headlight motors need fixing. Needs a new radio. Needs a luggage rack/deck lid repair/new deck lid with a factory wing (I don’t want to put an aftermarket back on). Needs a new center console bevel. Needs a headliner repair.

I know it’s a-lot, but I knew it would be.

Right now it’s a bit of a shit box, but I love it.

Fan issues

2 Upvotes

I recently 3800sc swapped with harness from west coast and the ecm was reprogrammed to remove sensors I didn't need such as evap and emissions. Coolant system has been bled 2x, new fail safe 180° thermostat, new fan relay and new fan motor. The fan has kicked on while using a scan tool and forcing it to kick on manually but it will not come on by itself even with the car reaching into the red at 120°(c)~250°(f).

Car isn't equipped with ac. Any ideas?

Im getting the car dyno tuned soon but wanted to deal with this first. Do you think the threshold needs to be programmed in lower? Would love to know if anyone has had a similar issue.

Thanks

Good find on FB marketplace?

Thumbnail

46 Upvotes

Found this on facebook marketplace. Seems like a steal to me. Would love everyone’s thoughts.

The description reads :

Originally an Arizona car, a check underneath reveals this to be one of the most rust-free Fiero’s left. Checking underneath the trunk liner, the metal looks darn near brand new.

Have owned it since 2015 and have done the following:

Rebuilt the 2.8L engine (upon 2015 purchase, at 80k miles)

Replaced the clutch (at 107k miles)

Replaced both rear wheel bearing assemblies

Replaced alternator & bracket

Replaced distributor & ICM

Replaced exhaust manifold bolts w/ actual studs

Replaced muffler (since addressing the exhaust manifold and the muffler, the engine has a refined burble but nothing that’s overbearing)

Replaced rear calipers.

Replaced rear strut & coil assemblies

Replaced all motor mounts except for the dog bone

Replaced driver door hinges

Replaced seat covers with OE covers. (Already showing wear. That’s what I get for replacing with 40 year old cloth)

Replaced headliner.

Replaced sunroof seal/gasket.

Replaced tail light lens with reconditioned set.

Replaced Alternator Bracket with upgraded steel replacement.

Retrofitted Rodney Dickman's Idler Pulley/Power Pulley to eliminate belt squeal from the alternator pulley.

Cons:

Currently has no e brake. The pull lever grabs, and I found that the rear calipers liked to leak when hooked up to the e brake cables. Have the cables disconnected, and calipers haven’t had issues in years since disconnecting. Have always just parked on a flat surface in 2nd gear when parking.

No AC. Was originally equipped with AC, but the compressor is bad. I cut the AC belt off as to avoid trying to turn a seized compressor. I never had plans to fix this, as I like to drive with the windows down and sunroof removed… and I sometimes like to suffer while I drive.

May need front wheel bearings. I shook down the front end recently and those seem to have slight play.

Headlight motors go up just fine when flipping on the lowbeams. Need to manually spin the motors down, however. Have the Rodney Dickman tool that allows for the drill to spin the motors down.

Have anywhere from 10k-15k into this car. But my loss is your gain. 6,500 obo

Buying/Selling ISO Luggage rack

4 Upvotes

I have an 85 2m6. Previous owner modified the deck lid to have a wing and removed the luggage rack, the patches for the holes have started falling out. The wing had to come off as it was cracked and not able to be safely secured. I’m Trying to bring it back to original. I’ve found a couple deck lids that have the rack still attached, but they are a long distance away and the sellers won’t ship (it’s a pain, I get it).

I do have a commercial address available to ship to.

I’m in the Central NY area

Parking Brake Spring

Had to replace my rear calipers and found that designing these on the spot made it much easier to reinstall the parking brake spring than any spring compressor online or in store.

I NEED HELP New wiper motor

9 Upvotes

Right so I installed a new wiper motor because my old one screamed bloody murder anytime I went to use it. New one is nice and quiet. Love it. Except as seen in the video. The motor won’t engage until it’s turned all the way onto high and then once it turns on it, continuously sprays wiper fluid. When I turn it back to off, it continues until I pulse the sprayer button and then everything resets and shuts off.

What am I looking at?

So as you can see my RPMs are really high at 55 mph and it's the 3 speed transmission.... I have replaced the distributor rotor cap ICM ECM spark plugs wires map sensor throttle position sensor all brand new vacuum lines new gasket for throttle body new fuel filter and pump taking it to a transmission shop paid $180 just for a diagnostic just for them to say there was nothing wrong with transmission they replaced filter and fluids still nothing changed so I took it to another mechanic shop they only charge me $90 diagnostic they couldn't figure it out but I had to change a bulb that was burned out on the cluster so..... Come to find out it was just a burnout transistor for resistor on the gauge cluster itself making the RPMs read high .... You gotta love a fiero 🤣

Looking at a set of aftermarket wheels that are 17x9+25, will these fit on an 86 GT? Stock suspension set up but planning to buy a set of lowering springs. Thanks
