the ecotec gearcase doesn't have the same mount bosses as the 60V6 case, so if your mounts were based on just the bellhousing, you should be good to go, but if they attached to the bellhousing and the gearcase, you'll need to get custom stuff made. I have a hybrid F23 in my car. but I was going to be required to make my own mounts for other reasons.

I actually spoke to thelin on the phone those brackets he sells are for the ecotec get-rag. Different f23 bell housing. Significant modifying needs to be done in order for it to work. The f23 getrag from the 2.2 cavalier vin 4 (correct bellhousing) bracket is only available from West Coast Fieros. It does take 6 months to make but I did not wait that long because I bought mine second hand, one used, the other never installed It is your only option. Fierorog used to sell them but had issues with them breaking. Dan does sell them but I don't think we need to go there. I actually have two sets of the West Coast Fiero brackets that I purchased from two different people. They are very well made and the welds are very professional. I havent decided what I would do with the spare set. These brackets should work perfectly with the rodney dickman poly motor mount or the west coast poly mount they are very similar in height. I will know in a few weeks how this will work out once I have my engine on the cradle.

Great info, thanks. That's what I figured- that the Thelin mounts won't work here... Let me know if you want to sell the spare set of WCF mounts

FYI, I am getting the correct F23 tool set from Kent-Moore and also the Transmission Assmbly pallet to hold everything together for the FY1 gear swap, and have a local mechanic helping me who has installed an F23 into his 3800 SC Formula. (Since I barely have enough brains to do an oi change by myself..) I definitely want the FY1 gearset- I had an F23 in a previous Fiero, but the mounts were crap built by you know who, and the gearing was really too short for the 3800. First gear was completely useless. You can borrow it if you decide to go with the better gears

The f23 stock gearing would be perfect for me right now. You need some additional parts as well. You need the spacer from spec so you do not overthrow the HTOB. You also need Rodney's flex slave line to adapt it to Fieroguru's threaded nipple fitting. In addition you will need a new clip for the Hydraulic Bleeder valve which ZZP carries or BMW has a similar clip that will work. Now that is considering If you break it removing it. In order for you to adjust the FWD transmission to RWD you need the special bracket and shift adapter. Thelin makes a good improved unit for that. The EP performance one is 300 U.S. plus shipping While Thelin's is 150 U.S. (all in) for the same thing. It is unknown to me which one has smoother shifting but the design and functionality is basically the same. Finally you need to purchase the custom length shift and select cables from California push pull.

Good info, thx. You may want to drive one with a stock F23 before you decide on gearing- it is really useless for a 3800SC. Both first and second are far too short- engine barely gets to breathe before you have to shift. It is very different from the OEM Getrag.

That's a shame Thelin doesn't sell those brackets anymore.
I also noticed the fierorog's were very thin in some spots. the holes for the bolts were very close to the edges.



guru also sold the line adapter back when i was buying this stuff. super nice.
The ep performance shifter bracket is very nice IMO.. extra money but if you want your engine to look nice it's a well made unit.
It is pretty large though. I had issues with it hitting my strut tower. If you have an 88 watch out for that.

The before is with Dan's mounts, after is with fierorog/thelins mounts.

are you installing the entire FY1 gearset into a 60V6 style case, or just doing a bellhousing swap?

Right now I think the f23 as it is will be fine. Im doing a slightly different setup than you probably had on your original car. It wont definately be perfect that is for sure. I do have an additional f23 that I may one day get a transmission guy to swap out the gearing similar like you have. Make sure when you buy a f23 that it has the hydraulic bleeder. Dorman makes one as well but goes for $100 U.S. you may buy another tranmission with that fitting if you are going to get another bleeder if it is missing. That is what I did. I was able to pickup two f23's one in Toronto, the other in Hamilton one with 96k on it and the other with 110k on it. Good shape for under $200 CAD each. Other people have mentioned that the f23 is very similar to the 282 but again maybe your setup was tuned differently. The EP performance bracket also has a bushing that tightens up the shifting. Don't know what difference that may make but the Thelin setup does not come with that fitting.

This is the shifter bracket I purchased. Should be a tad smaller than the EP Performance one.

The 2.2 transmission with the bellhousing that bolts up to the 3800 has a 3.9 final.

The later Cobalt XFE transmission--which I think is the FY1 mentioned elsewhere in this thread--has a 3.63 final. The XFE transmission is geared almost exactly like the Fiero Getrag.

Swap the 2.2 bellhousing onto the XFE transmission and you have a fairly modern gearbox that's geared exactly the same as the original.

Correct- that is exactly my plan. The 3.94 final drive (in my experience) was really not adequate for the high torque, low revving 3800 motor. I am fortunate to have someone who has offered to help me with this, as I don't have the skills to do it myself.

Quick question- any feedback on benefits of installing an LSD on the F23 transmission? What , if any, are the advantages?
