Is it possible to Supercharge a 3.9Mpi (89 Fairmont Ghia) or is Turbo the way to go?

you can do either...
but it all comes down to what you want to spend and what sort of power you want :)

how fast do you wanna spend???

search or go back a few pages..Blower is vertually fit and use as they come in kits.. Except a few, most turbo fitments are custom made.But "FUN" fitting yourself !!!First spend $$ on ecu and fuel system.Bigger injectors and pump etc..The actuall turbo & manifolds is not that expensive

Turbo is much more responsive as the boost comes on earlier and there is more skope for further development down the track, mine made 250rwkw where as the blowers usually make 250fwkw

P.S i have a turbo kit for sale if your interested $2500

who told you turbos come in earlier?? a positive displacement supercharger boosts off idle not at 3500 rpm or further, and if the correct supercharger is chosen power out puts are a lot higher how can u say that a turbo 6 makes 250 at the wheels and a supercharged at the flywheel? do u have all the specs or are you just backing up your decision in buying a turbo?.

Why not give facts not what you may "think" is correct.

Quite simple really, if a blown car makes 14psi at 6000rpm than it will make 7psi at 3000rpm where as the same thing in a turbo will make 14psi from around 2000rpm all the way through to 6000rpm so you tell me which one has more power at 3000rpm, as for my power figures CAPA superchargers does a kit for I6 and it makes 240fwkw and mine made 250rwkw so its not a guess. Superchargers rely on engine rpm for boost and take power to make power where as a turbo uses wasted energy in the form of exhaust gases which is free power. Next time you get on your High horses mate maybe you should know the facts before you go opening your mouth and showing your lack of knowledge. After all horsepower heros was won by an all turbo field

what you have stated is load of bullshit how many "high Boost" turbo setups do u know that make 14psi from 2000 rpm? do you know how small the turbo has to be to spin up that much boost at 2000rpm and then the losses you would get from over heating the air once that little turbo was spining its nuts of at 6000rpm?

and explain to me again why so many cars use nitrous in conjuction with the turbo setup to get it off the line where supercharged cars dont need it?

and why twin turbos are usually set in sequential form the small one boosts at 2000rpm then dies and the larger one takes over at higher rpm? you gonna tell me know you where talking twin turbo all the time i guess right?

dont try and rip people of selling your left over crap by telling them it is far supereior than anything else as for capa and they are only one of the companys doing supercharging they can supply you with all the parts to make a hell of a lot more power than you claim, becuse much like a turbo you can run an intercooler on a vortech allowing you to run big boost not the bullshit 6 or 7 pounds you claim so how bout you try and bullshit to someone else who doesnt know.

If you care to read i said around 2000rpm and i run a large TO4 on my car and it makes14psi at 2000rpm and my old TO4 was 14psi at 1800rpm. The falcon 6 is a big motor and will spool up low in the rev range and you have to remember that most of the cars you are talking about are small sixs or 4 cyclinders not 4litres and 6cyclinders, i think i am in a position to speak about this as i have a turbo Falcon and have had a Supercharged EL XR6, how many forced sixs have you built my all knowing friend

im not starting another war if you beilieve this crap you buy his kit and see how you go
