I just finished my f23 swap on my 86 2.8l fiero and while bleeding the clutch im getting fluid leaking out of the bellhousing. I thought that when I used the stock clutch and flywheel I dont need a spacer for the HTOB? Obviously I either overextended the HTOB or I have a defective one. Do I need a spacer for the HTOB and what size does it need to be? Thanks.

Reason for the spacer is the depth of the F23 bell housing so the spacer on the HTOB is still needed when mated up to the Fiero stock engines. Dan

This was suppose to be the first test drive but since I have to add a spacer and take the tranny out I might as well put a new clutch in it. What clutch did everybody have good luck with for a 2.8?

I already looked through a couple hours of posts and i couldnt find what i needed. The spacer size is most likely different for a v-8 and a 3800. I have the 2.8 that came with the car but its a 3.1 stroker which doesnt matter with the spacer sizing.

try and PM Justinbart or Dark Horizon . I would think the spacer for a 3800 would at least be a good starting point and I think I remember that Spec makes one so get that part # .I think fieroflyer has that info too . I am not that knowledgeable on the subject , just going by memory here .good luck .

.250 or 1/4 inch as some call it is what pretty much all of the ones I have done needed

Was this an issue with the a Getrag clutches? I do know that the Muncie clutch and Getrag clutch use different throw out bearings and none of the early F23 threads even mention it being needed, but almost all were aftermarket Getrag clutches against 3800s...

I believe the real issue is that the Fiero master cylinder has a larger capacity than the J-body's... you can probably achieve the same results by spacing the master off the firewall or limiting pedal travel with a block...

If you take the time to do some measurements of both trannies and how much space and movement there is off the throw out bearing on the Fiero and the HTOB on the F23 you will find you come up with a difference of approximately 1/4 of an inch more which causes the HTOB to ever extend and fluid leaks past its seals. Placing a block under the clutch pedal or moving the slave might work but the proper way is to use an HTOB spacer and be done with it. Dan

Along this same discussion...............
Is there a possibility that the F23 has a LSD option?
If so how would it be designated on the case? vin? anywhere?
Is there a particular vehicle that it would have been in?

Im not 100% sure if you can get one already with an LSD but I know you can make it an LSD. OBX and Quaife offer what you need to do that. Would that be something that I should do when I take it out again?

The aftermarket units are about a grand to buy.
I have the Engineered Performance unit in my current 282 and it's not that great.
I do know the Quafe unit is available but was told some time back that a few cars were built with it.
Just trying to find out if the info was correct and if so where to look

I believe some of them were made with it but they are newer around 2010 or so which would require swapping the bell housing with an older one to make it bolt up to the Fiero engines.

The OBX one is about $400 shipped.

The SBC/F23 I am working on has a LSD, but it is a quaife and was added.

That I did not know, and am pleasantly surprised.
Makes doing this a bit more palatable.

To insure you have the best experience possible with an OBX Limited Slip Differential for the F23...

Edit: The link is from 2011, whether the issues have been corrected in the current product, I cannot say.

Called SPEC and spoke to Jerrimy. The spacer needed is the .250" and the part number is N1774-.250 Bearing Cap. They told me it is $49 plus shipping. Hope this info helps others as it was hard gor me to find.

I had an extra htob and cut the hardened part off that touches the clutch fingers and made a 1/4" spacer out of it and welded it to the new htob. Now it works perfect.
