I was thinking, and I have a question.... If the intake can be installed onto the 3800, then could the supercharger be installed onto the 2.8? Would that be possible?
It is possible there's a few ppl out there who have done it. Unless you have an endless amount of time and all the parts for free its not worth the effort. Even with ported heads cam valve springs and massive work already done to your 2.8 it won't get you far at all... if you are dead set on building the 2.8 up fab a turbo setup up.. if you truly want power and play start reading up aand save up for a swap.
The 3800 and 2.8 are two different engines and the intake manifolds are not interchangable. There is no 2.8 "supercharger intake" that fits the 3800's M90 S/C.
Debbie downers. .... Ohhhhhhhh well, it was the thought that counts? One question, though.....on that ford supercharger, I wonder how much pwr is produced....i saw a belt-driven turbo, about the size of an alternator once....not sure if it did anything except make noise....really low profile.
The key difference between a turbocharger and a conventional supercharger is that the latter is mechanically driven from the engine, often from a belt connected to the crankshaft, whereas a turbocharger is powered by a turbine that is driven by the engine's exhaust gas.
Thanks for the clarification. I didn't know what to call what I had seen because it was belt driven, like a supercharger, but had a turbine, instead of a screw type compressor.
Also, I agree with the concept that if one where to want crazy power and have the need to open up the engine to accommodate I.e. lifters, cam..., then it makes more sense to do a swap. I'm just looking at tweeks and bolt-on mods...nothing invasive.
Ok. I just read an archived post on the 7730 swap. WOW! that seems like a lot of work just to squeeze a 2.8....but I guess you can't have it all. Looks interesting, though. I spouse the point is engine management and efficiency? Looks like a swap to 3.4 would be easier. I'm starting to understand the popularity of swapping!
There are a lot of benefits of the 7730, smoother idle, better throttle response, fuel economy, etc. There is a lot of info on it, and Sinister Performance has info on how to repin the ecu to work with the Fiero on their website: http://www.gmtuners.com/files/index.htm
Thanks. I will read up more on the 7730. Also, once I figured out what to call it (saleen blower), I found what I was describing before....an alternator-sized supercharger/blower....
this approach looks promising for low psi applications. Does anyone have experience with these?
Thanks spider1. I'm learning a lot fast! There must be a reason these aren't being discussed more on this forum.. I wonder why? Are they unreliable? It seems to me, one could fab one of these from a junk yard alternator case and a turbo...remove the band clamp from the exhaust side and housing, then remove the fins, exposing the shaft, then turn it to fit the bearing and pulley in the doner alternator shell. I'm just thinking out loud.....
Turbochargers can turn 150,000 rpms. Centrifugal Superchargers are designed with internal gearing and small pulleys to increase rpm too. You would be hard pressed to make anything DIY. You can do what many of us have done; buy a junkyard T3 turbo, weld up a turbo crossover manifold, wire up a turbo friendly ECM, drive it like you stole it. Ok, maybe there is more to it but if you want more power from that tired 2.8L add a simple turbo. Then when the engine blows up swap in a true Supercharged 3800. After I crunch my turbo 3.4L I want a turbo 3800.

Anything is possible... but it depends on vision, fabrication skills, money, time... and what you want it to look like...
The first issue that you are going to deal with is the fuel injectors. They sit under middle of the stock intake, which means you can't just mount the SC right in the center. You either have to fabricate a new upper plenum (maybe something similar to the trueleo) or cut a hole in the stock intake. Either one is probably going to put the SC high enough you have to cut a hole in the decklid or remove it...
People add a superchargers to other GM cars... but at what cost...
Isn't it strange that after a bombing, everyone blames the bomber, his upbringing, his environment, his culture, his mental state but … after a shooting, the problem is the gun?

Absolutely not. The inner workings of the compressor side of a turbo and centrif supercharger are far more complicated than that.

Although not the most powerful one, the pushrod 3.4L engine swap probably is the easiest swap there is for a 2.8L Fiero, f85gtron.

thismanyfieros is quite correct about that.
Also, if you elect to go with a pushrod 3.4L engine swap, you or your mechanic likely will find a write-up authored by fellow PFF member, crazyd, to be most helpful, and one containimg some very practical advice.
Titled, "Fiero 3.4L F-Body Engine Conversion" ( http://fiero34swap.eleventenths.org ), that succinct write-up outlines just about everything you'll need for a 3.4L engine swap into your Fiero.
Good luck to you regardless of what project you take on.
.... Ohhhhhhhh well, it was the thought that counts?
