It will rasie heat inside the engine compatrment and somewhat the engine itself..

Not unless you consider a blown motor a problem....that motor would not handle any amount of boost...plus the blower would be more the the motor itself in terms of money. Blowers are a not for someone that does ot have deep pockets...its not a bolt on and go...better just to do something wit the exhaust..

Unless your 2.8 engine is in very good shape, I would not recommend this approach.  It is likely to shorten the lifetime and is not really a bolt on application.  Be prepared to spend some bucks for customized pieces and plumbing.  I believe that it is actually easier to install a turbo on this engine than a blower.  There have been several turbo 2.8 Fieros so you may want to do a search on Pennocks and see any comments on them.

I like boost and have both turbo and supercharged cars, but think you would be better off long term to do something else on a stock 2.8.

If you want an agressive sound,then you should modify the exhaust (useing a bigger muffler and larger tubeing).I agree,a super charger is expensive,your better off going with an engine swap (you could allways sell the rebuilt motor).Some wrecking yards have a half off day,so you can save even more money.The only minor problem is the gasket for the supercharger,slowly degrades,but isn't a problem untill well after 100,0000 miles.Then you would probubley see a coolant leak. 

Hi,

If you are interested in sound but less interested in power, and very capable of anything engine related and not afraid of some bespoke work, then a throttle bodies conversion is the way to go.

Basically you replace the entire inlet system with individual throttle bodies (from Webber/Jenvey, or even bike carbs). Of course you will probably need new a EFi management system too.

Just search Youtube for throttle bodies to hear how they sound... You will be impressed.

By the way it has been done on a Fiero I think, although I really don't know much about Fieros.

HTHs.
