Those are nice! I had gotten the same things... did you get yours on eBay? They can be snagged pretty inexpensively with a little hunting (and careful reading! I almost bought one kit that was used and missing two critical parts).

I've read so much about OBX being hit or miss (multiple threads on guys taking them apart to show where stuff wasn't assembled right), I just bit the bullet and picked up a Quaife. I am jealous though - your trans looks much nicer on the outside than mine did, and the gearing you have, that's the "favored" gearing for highway driving, isn't it?

Yes its the favored gearing. since i am running a fairly strong ls v8 the f23 was the only way to go in my opinion

ok, it about time someone tried this combo.

So where's the build thread.

A lot more than that is coming.

YES, so I can copy it next spring.

updates?

We ran into what (in hindsight) were small hiccups for doing this swap on an SBC. I don't want to get into details until things are finalized and we're sure the kinks/hiccups are worked out - nor do I want to post anything inaccurate, since I'm not the one doing the work, I'm just the part-time tool gopher.

EMC is planning on doing a very detailed swap thread for it though once it's done and everything is working.

That would be nice. I have been picking up the parts to do the swap myself and though I know I can figure it out, it's still nice to see one completed and customize it myself.

F23 on a SBC?

quote Originally posted by nosrac: What is the 1st 2nd shift like? 282 Getrag or shorter?

I haven't driven in a F23 car, but I do know that a 282 first and second gear drive ratio's are 12.635 and 7.4005 respectively, and the 287 (F23) is 13.7472 and 7.7568 respectively.

Just read through this whole thread and still a bit confused...what clutch/flywheel setup would you need behind a 3800? (with the f23)

[This message has been edited by 85sliverGT (edited 08-16-2011).]

There is limited clearance inside the bellhousing for the pressure plate. All of the clutches that are used with the old Fiero Getrag (282) will work, but you have to be conscious about how tall the pressure plate is. Different clutch suppliers use different height pressure plates. The smartest thing to do would be to pick out several clutches you like and will meet your needs, and then choose according to which has the shortest pressure plate. Someone here had luck using a standard clutch without paying attention to the height of the pressure plate. Another ordered a specialty pressure plate which turned out to be slim profile, and of course never had a problem. Keep the height of the plate to a minimum and there shouldn't be any problems.

With this SBC swap, the adapter gave us an additional .20" to work with, so I ordered a .29" throwout spacer from SPEC and don't anticipate problems with pressure plate contact.

The day I hand the keys back to Trinten, I'm planning to sit down and submit a very detailed write up. Everything mentioned in this thread and more will be condensed down to a full overview and step by step tutorial.

That would great. Thanks for the info. So would the same machined flywheel that would normally be used on a 282 getrag to 3800 would work? Do you know the thickness of a pressure plate that clears? I have a couple different ones here to check

[This message has been edited by 85sliverGT (edited 08-16-2011).]

Yes, you would use the Camaro flywheel turned down to .840". I don't know the thicknesses of either pressure plate I mentioned above. I'll tell you that the specialty pressure plate was a SPEC "super clamp" pressure plate on top of a Spec 3+ clutch. You could always call SPEC and ask how tall that pressure plate is.

the step by step would be great ty l67

Spec tells me the Super-Clamp plate is the same thickness as there other pressure plates for the fiero, so assuming everyones info is accurate, you can use the same clutch, pressure plate, and flywheel as you would with a normal fiero getrag to 3800 conversion.

I'd strongly suggest you get a measurement from them.

For example:

Clutchnet makes multiple pressure plates for the Fiero. CaptFiero did a rebuild on a duke some months back, and the PP he got from them was too tall and was rubbing the bellhousing (he had taken measurements and gave details on the height/collision issue). He contacted Clutchnet, who sent him a different pressure plate, and it was the proper height.

So there can be pressure plates that will bolt on, but will have clearance issues, even in stock engines! Now from reading L67s post, if you're going to get the superclamp from SPEC, then you should be fine. If not... definitely push for measurements.

Still planning to deliver guys. I've been chasing my tail with small engine quirks. Tutorial will come soon.



I was on the road going through the gears a lot last week - what a sweet transmission.

That is really looking pretty sweet L67, you say you had it running in the car and jammin gears? I look forward to your full disclosure of the build and what you did and would do again or not. Nice work man. BTW, My wife and I have been REALLY enjoying the Hearts of Space Disks. We listen to them daily now... Hope you are doing well and peace

Pete

Wow, that looks so awesome Paul. I would love to do something like that myself, but I'm more interested in details of getting the F23 to work with the shifter cables, mounting brackets, and clutch(es) with say a 2.8 or 3800.

[This message has been edited by mattwa (edited 08-30-2011).]

To my knowledge, the shifter cable and bracket setup will be the same on the 3800 swap.

All of the complications involved with putting it on the V8 dealt with mating/starting issues. So the tutorial should still apply.

Obviously, take this with a grain of salt, L67 will definitely correct it, but it was my understanding based on some of the questions/things he and I talked about.

I agree, you're right, but I didn't mean that I didn't want to read about the SBC part, as I certainly do.

Thanks Pete. Glad you're both enjoying them, they took a little while to put together. I expect we'll meet at a TN show or RFTH this year. I wasn't "jammin'" gears, but certainly putting it through its paces. It's unbelievably smooth and fun to downshift.. Several times I had to lift off the clutch to be sure I was in reverse, even though I distinctly put it into the right gate. The new clutch pedal feel is worlds ahead of the old because of the self adjusting hydraulic throwout. I'll go into detail soon.

It's going to be a no brainer installing it onto either of those engines, or 4.9 etc. I've already taken care of the cable, clutch, and bracket work. More on that later.

I'm having trouble actually finding an F23 around here, unless I'm freaking blind. But yea I was just curious on the bracket work.

I really wish more of the XFE variants of these transmission were available. I've been actively searching the last few months and they are pretty scarce- I know someone recently acquired one a month or 2 ago here.

XFE F23-
First:
3.58
Second:
2.02
Third:
1.35
Fourth:
0.98
Fifth:
0.69
Reverse:
3.31
Final drive ratio:
3.63:1 (15-in tires)

To add to what Trinten said, the tutorial will be universal. Any of the engines with the 60* pattern will be a piece of cake. Each chaptered section of the tutorial will be appended to include additional work needed to install the transmission onto engines using a SBC adapter, Archie flywheel, and custom starter/oil routing. Don't buy anything if you're planning to swap soon (like shifter cables), wait for the tutorial, I've got some cool stuff up my sleeve.

This is really exciting, I can't wait to put a manual transmission behind my sc3800 and not have to baby it worrying that I will grenade the transmission. I understand the f23 isn't bulletproof, but having a little more room to play will make it A LOT more fun .

Nice work, looks great!!!! I think it's time I start looking for one of these. Ray

Sounds like there's going to be a lot of valuable information in this write up! Looking forward to checking this out!

Any update for us?

I'd love to see this tutorial, I've got my engine and trans hovering over the cradle, and I'm running into a clearance issue between the rear of the trans case, and the cradle...

I agree, I'm curious about what you did in that build. Any updates?

The F23 SBC car's been returned and on the road for several weeks now, and I have all of the information in front of me, I've just been too busy to compile it - I stripped a Fiero to the space frame the day after it was picked up, and I'm finishing one of two engine swaps in the past two weeks. I swear I'll get a minute soon. I expect it'll take me 4-6 hours to sit down and write a formal article that's clairvoyant. I just haven't had that time yet. After I finish this swap, I'm putting down the tools permanently, so I'll have lots of free time to do whatever I choose, and the tutorial is the first thing on my list.

Yup, it's been great, and I've been gradually increasing how aggressive I get with it. There was one small hiccup that was discovered during the RFTH meet that was last weekend, but I don't think it'll be a major issue to permanently fix - and it is SBC specific, so shouldn't be a concern for the 3800 crowd.
