Started reading on the forum about supercharging a 2.8 and saw that one of the best ways to do it with minimal work and extra parts thrown at the engine is the 3.8 Thunderbird supercharger. Anyone done it before? Not looking to make tons of boost just a quick gain. What would I need other than the SC, and intercooler? Please don't flame me, I'm here to learn.

So where did you see that?
People have been dreaming about using an M90 in a 2.8L since 1999 when this forum went online. Nobody here has ever done it as far as I know (it won't work on top - too narrow between the heads to fit FI as well). http://www.fierosearch.com/...20v6&Action=DoSearch
Back in the 80's, B&M made a 2.8 supercharger for RWD 2.8's. I think someone in the midwest bought the tooling but never saw anything further. If one were to show up on ebay cheap??? In any event I suppose it would require deck mods as it was for a carb set up.

I have thought about this setup, but haven't gotten the nerve. I have seen it on 2.8 S-10's and have even contacted Mark Fageol personally (nice guy). Maybe call him and ask some questions?? http://fageolsuperchargers.com/ https://www.facebook.com/FageolSuperchargers

if someone made an oval or rectangular plenum that bolted to the top of that supercharger (where the carb or throttle body mounts) , mounted a throttle body off the backside near the stock location and then mounted injectors horizontally along the sides of said plenum...would it work and or fit under the hood? the upper intake sits pretty high on the stock 2.8. thus you could use a 7730 computer with a 2.8 or 3.4 ( the better choice for the mod) and a dis or even a regular distributor set up. i saw somewhere where an intake had the injectors mounted along each side of the top of the tunnel in a horizontal position and the runners ran down under them to the heads. just a thought, al

Ace, what about a TBI set up and using a hinged, snorkel (over the roof) intake? I have seen the snorkel before and although at the time I thought it looked weird, if it would allow this application, I would embrace it with open arms.
Yup, that would be ean easy remedy to some major engineering and fabrication. However the unit is already set up for the TBI and just the fab and mod to the decklid would be necessary. Of course either way you go there would have to be changes to the ECM and harness (I suppose).
Peace!!

wow, that is really a sweet set up! i was just thinking sleeper, keep as much hidden as possible and then when someone tests you on the road....they don't know what they're in for. with the above set up, it's kind of hard to pretend you're stock...lol

I have the complete T-Bird supercharger setup, including an M-90 Eaton SC, inter-cooler, TB and all of the interconnecting tubing. Everything is in great condition.
Call me for pix and/or pricing. Trades considered.
Well Ive been researching this immensely lately and I picked up 2 M90's locally and got a good deal on them. Both are clean and spin freely. So here's some pictures I took:
They both pretty much look like this:
So Im interested in this back piece. The whole piece is bulky and takes up quite a bit of space in the engine compartment.
Im wondering if most of it can be cut off and blocked with a plate. And have the throttle body come out through the back facing the stock throttle body position. Something like this:
The part with the vacuum actuator is a bypass valve. 3 & 4 might be throttle heaters lines. 5 is another vacuum source.
You should probably ditch that whole assembly since its so bulky and come up with your own piping. You could run without a bypass valve or run a bov assuming you are going to have an intercooler piped in.

I've searched and searched and could not find anyone who's done what you said you read about. Got a website for that? I mean, didn't they document their work and be able to help you?
Are you sure it wasn't the TURBO-charger from a Thunderbird you were reading about?? That's the only reference I've found between a Fiero/Thunderbird.
How about taking the output air unit off the supercharger, machine the 2.8 upper intake flat on the top and cut a hole it it to match the hole in the supercharger output. Now drill access holes in the bottom of the upper intake so you can bolt the supercharger directly to the upper intake. cut off the air inlet on the upper intake and plug it up. You are finished up if you can mount a TB to the supercharger intake with some kind of blow off valve. Larry

I like your idea but it would be way to challenging. In addition, there would be no way to cool the intake charge via an intercooler which would for sure cause kmock
Lots of supercharged engines don't have an intercooler, not a show stopper. Complicated? Take off the upper intake, take it to a machine shop and machine off the fins. Cut a hole in it and bolt on the supercharger. Put a large cork in the intake. You are done. Larry
