For the Fiero 5 spd getrag, correct?

That's what I ordered.

Perfect, thank you.

Finally progress made this weekend...

I have to say, I had mixed hopes on my mounting process as I had a poly Rodney Dickman engine mount and dogbone, a Roger Thelin rear trans mount bracket with a stock mount and a FOY front trans bracket and a Dodge truck mount...

Needless to say the RD and Thelin products fit like GM made 'em themselves, whereas FOY's mount... well this is what I was shown would happen:


And this is what I got:


Basically the bolt holes in the mount sat on the 90* bend of the front side of the cradle crossmember. The bracket is being cut and rewelded to move the mount back this week.

Other than that, the Exedy clutch part #04088 for the Pontiac Fiero has no clearance issue whatsoever with the bell housing. Granted this is isn't a fancy stage three plus super ultra clamp clutch, it's a stock replacement on an ATP 88 flywheel, but Jncomutt's observation on pressure plate design proved correct again...

Thanks.

I have the 3.94 gearing in my car and I wish I had driven this trans before getting it installed. The transmission is great, but the gearing sucks for the 3800. First gear and much of second is pretty much useless. The lower gear ratio swap would have been nice...

You only pick up about 3 and 5 mph in 1st and 2nd respectively.

The 3.94 gearing is great for "performance driving", makes a 3800 N/A feel pretty quick, but for a DD in traffic, it sucks because of the high level of engine braking it provides.

to upgrade your pressure plate... take your new stock gm 2.8 pressure plate with the old one as well to your local clutch store, most cities have them. have them take them both apart and reassemble the new pressure plate with one extra spring per location than when stock. it will increase your lbs per inch holding power by around 500 with minimal pedal feel change. this is a low buck option with good results. so if your stock gm 2.8 pressure plate had 1200lbs per inch holding power stock it would now have around 1700. that is similar to most heavy duty units. would be fine for a spirited street 3800sc. if you need more get a stock sachs pressure plate new for the 2.8 they start around 1700lbs so the mod would yield around 2200lbs, similar to spec 3-4 units. just my .02

Not sure what you're talking about, as the front wheel drive clutches use diaphragm springs.

Sounds like you're talking about a coil spring clutch.
