Lunatic is a great guy- very humble... considering his skills!

There are some updates here http://www.gtfieros.com/php...wtopic.php?f=5&t=759

I am not sure if he plans to sell more of them- feel free to PM him about his intentions. He is using a WCF engine mount I gave him, so the F23 mounts should work with the other engine mounts that are similar to WCF.

I hope this helps

Great looking work!! Your reputation with Cam-A-Lot is well deserved!!
How are the mounts coming along? Any updates? I know it's winter and if your like me,
everything slows down.
Not wanting to highjack this thread, but maybe your work can be included, It's AMAZING!!
Wondering if you were going to try to sell a few also.
Thanks!!

Hey Doug.

Thanks for the compliment. In time, I do wish to offer a "nice" set of F23 mounts to the people on this forum. The thing is, they have to be designed and built well. Anyone can take some steel and cobble something together. I don't go down that road. I've seen too many hacked items and poor welds on way too many forums. I have access to the state-of-the-art equipment so why not use it? It only makes sense.

In Pete's case, he wanted to have a set that bolts into the existing holes on the 88 cradle. I understand that some don't want to hack up a nice cradle. Hence the time required to do this R&D takes longer. I might go through a few revision changes before I'm satisfied with the end result.

If this was my car, I'd cut the cradle and use a four point mounting system to mount the driveline. No dog bone(s) and I can put the mounts where ever I want. Since this is an F23 thread, I can say that as it's related.

After I get one set fully ready to go, I'll see if there are any tester's available. I'd like to see what they have to say and see where other issue's might arise. I'm not there yet but I'll start a thread when the time is right.

Sounds great ! I haven't even started my swap yet which will start out with the original 282 but like to think ahead. Let me know when you are ready to start selling your F23 mounts for pre 88 Fieros.

Bump. I'm in the market for an F23 for my 3800SC swap. Looks like the gearing I want is in the 00-02 Cavalier/Sunfire? How do these transmissions hold up over time? Obviously low miles is generally better, but is there a mileage threshold that I should stay below? Also, has anyone actually made and marketed mounts? I've seen a bunch of "I'm going to make mounts" posts, but they're all from 2011-2013.

The transmission you want is from the 00-02 Cavalier/Sunfire with the same bolt pattern as the 3800 (make sure the donor car is not an Ecotec). However, the gearing is not great. There is a better gear ratio available from later model Cobalt SS cars I believe- just search the forum for the specifics.

My F23 has held up well, and I have hammered it quite a few times. It also seems to be a plentiful transmission in case you break it. Maybe someone who has changed the gearing can chime in to how much difference it made? The stock F23 gearing is more suited to the underpowered 4 cyl that it originally cam with- First gear is pretty useless with the 3800 and it does rev a little too high on the highway

Is there anyone making the brackets and mounts needed to use the F23?
NoLimits DEC 27, 06:01 PM
Bump. I am newbie here and been doing F23 research for months and decided to join yesterday. I also decided to make a donation and ask others to consider giving a little

Now, I too am in the market for F23 trans mounts and cable brackets for my 87 ZZ4 V8 Fiero with TH125. I have a F23 (FY1) with V6 bell housing and MT parts cars. At this point I am ready to purchase the key components for the swap.

- F23 Trans Mounts: Purchase from ? or fab myself and take a little more time
- F23 Shifter Brackets: Purchase from ? or fab myself and take much longer
- F23 Starter Mount: Purchase from? or fab my self, I suspect my only open is to fab this one
- F23 Shifter Cables: Purchase stock 88 V6 Select Cable (74") from Push Pull along with longer customer F23 swap cable. Length would be 86.5"???. Or just ask for Dan when ordering?

- Flywheel: 153 steel V8 Fiero flywheel for modification to 142, or are there any other feasible solutions here?
- Clutch: Spec 3+, Superclamp flywheel (3800) or Clutchnet 6 puck sprung hub with 2x "red" pressure plate. Hmmm Im thinking SPEC based on a few posts but not sure I understand why the Centerforce DF will not not work?
- THOB Spacer: .270" HTOB shim for SBC. May need to measure first.
- HTOB: Which one for a hybride F23 case and V8 swap I donnoo. Perhaps this depends on the clutch I choose?
- HTOB Adapter: McLeod #139160, Summit Racing
- Clutch Master Cylinder: Reuse stock unless there are better options or choices to select from?

kaistallings - Thank you Sir! So did the images from the bell housing, flywheel, clutch, spacer, shift cables, starter and VSS sections earlier in the L67 post get lost forever?

Hi NoLimits -

Though the pictures are gone from both threads, this thread breaks the information down into sections that will answer many of your questions.

http://ncfiero.com/Forum/viewtopic.php?f=8&t=3

The select cable is a stock Getrag select cable, the year should not matter.

The shifter assembly on the transmission that Emc built for me was re-engineered by FieroGuru. He may have covered some of it in this thread --
http://www.fiero.nl/forum/F...3/HTML/000142-7.html

Flywheel - ironically when the F23 was first put onto my SBC, the oversized flywheel was turned down to be the same size and gear-tooth as a stock V6 Fiero flywheel. I don't recally if FieroGuru had to change it at all when he did my EFI conversion.

The HTOB doesn't matter which clutch you pick. The HTOB used by the F23 is the same one used by the F40, so any HTOB you can find for those transmissions should work.

The spacer we used was a .270" one.

I used the stock master cylinder.

I know I didn't get to all of your questions, but a lot of them it seems you found the right info when you were posting the question. Hopefully the NC Fiero thread will have the rest of the details you need, and the revised shift arm for the transmission on the PFF thread I linked secondly.

I can ask EMC if he has the pictures still and send them to me, and I can repair the links on the NC Fiero thread.

Great thread overall. Thanks to everyone who has contributed info. In particular, I'd like to send a + to the most recent posts' members:
Kaistallings for making a .pdf file of the original F23 Turorial.
Cam-a-lot for info and links to the GT Forum info on this F23 swap topic.
Lunatic for great info and some awesome 3D modelling and design work.
Trinten for concise answers to NoLimits questions.

I currently have a '84 notchback I bought two years ago. I like to track-day the car...it is awesome to blow by 911s, Boss 302s, Camaro SSs, and the like. It has a Gen I SBC 355 V8 swap and many custom body mods. But it still has a stock 4-spd tranny. It is time for me to upgrade the tranny and refresh the engine. So this thread on an F23 upgrade is very useful to my research on what tranny I might go with. I have a low miles stock '86 Fiero Getrag 5-spd in great condition that came with the car's spare parts inventory.

I am still wondering if I should just pop in the '86 tranny or go with an F23? Or go with something newer even like a 6-spd F40 with a Quaife LSD? My main criteria for selection is durability and longevity, secondarily is ease of installation. And I would love to have the extra performance capability of an LSD. What do you guys think?

Thanks in advance for any replys.
