oook.
so i'm new and i've just been reading over a few of the topics on here.

i have a 93 legacy N/A and i was just wondering if i could put a s/c on my car.

if so....
what brand?
and how do i mount it?

personaly, id rather get a centrifugal s/c
like a Paxton or Vortech or Procharger, theres several other but those seem to be the best, to find the right one youd go to the website, they usualy have a thing that shows which s/c is best for your car, it goes by the power output, the less power the smaller s/c and read reviews about them to see who you think is better

you want a self contained s/c, so that you dont have to tap holes in your oil pan and run lines up, that makes alot of complications

you should think about doing the 2.5L head swap for better fuel and air flow, youd also need some way to tune it so think about piggy back or stand alone ECUs

ok. so how does a centrifugal s/c differ from a normal s/c?

and does a centrifugal one hook up differently?

and also...where would i find a 2.5L head to put on my car?

i recently bought a ProECM but will i need a better piggy back than that?

this is the Eaton M62 with a clutch, its a roots-type blower
http://club.corrado.free.fr/prepa/eaton/M62.jpg

this is a centrifugal supercharger, think of it as a belt driven turbo
http://www.carcraft.com/techarticles/p1 ... _small.jpg

they are much more compact, a little easier to mount most of the time since they are smaller, much easier to run intake piping since its made to run pipe and not sit on a manifold, you could use the intercooler and hood off a turbo legacy
roots-types are the most cost-efficient but the least efficient at making power because it has no internal compression, its external compression also creates more heat than that of a centrifugal

so youll get more power from 5psi in a centrifugal than 5psi on a roots, but if you want the most youd get a twin-screw s/c
the roots is also not a compressor, it is a "air delivery system" hence the name "blower"

ok.
so then where in the engine bay would i mount it?
like next to the alternator?

and my other big question is would i need to buy a new ecu?

aspect · Post by **aspect** » Mon Sep 11, 2006 2:37 am

You would probably mount it between the air filter and the throttle body.

asc_up · Post by **asc_up** » Mon Sep 11, 2006 7:21 am

yeah that's obvious......
but what would it run off of?
do i just mount it next to something and have it run in with the pulley system?

Did you bother to look at the link I posted? Its loaded with pictures.

No, he didn't bother. That requires thinking.

asc_up · Post by **asc_up** » Mon Sep 11, 2006 10:19 pm

ooo that was a good one.

Murphy · Post by **Murphy** » Mon Sep 11, 2006 10:43 pm

ooo burnnnn

if you didnt look at it you realy should, its a very interesting setup he has, a centrifugal would be mounted sorta the same manner as that one since that looks like the most simple way to do it

and youd need a new fully tunable ecu or find some way to tune your current one, theres a home-made thing that you can do but im not sure if it just looks at the data or you can actualy tune

douglas vincent · Post by **douglas vincent** » Tue Sep 12, 2006 5:33 am

Except for the fact it blew up because I was running it un-intercooled, I was hitting 15 psi supercharged with the DOHC heads. Of course I was getting that because I WASNT going through the intercooler.

asc_up · Post by **asc_up** » Tue Sep 12, 2006 5:58 am

hahaha ok.

so basically...
i can throw down about $500 for a used s/c.
another 800 for an ecu.
and possibly more for an intercooler?
lol.

now i'm starting to rethink this.........

douglas vincent · Post by **douglas vincent** » Tue Sep 12, 2006 6:25 am

#250 for supercharger,
$250 min for intake and exhaust plumbing from supercharger
$100 min for bigger injectors
$300 min for intercooler and piping
$250 min for new clutch, NA dont hold
$470 for SMT6 (piggyback computer)

$? or ability to do all work yourself.

It adds up.

asc_up · Post by **asc_up** » Tue Sep 12, 2006 6:38 am

lol money and being able to do it all myself are the things holding me back.

ahhh.
i just want horsepower so i can race honda's and not have to worry about losing too much. lol.

Murphy · Post by **Murphy** » Tue Sep 12, 2006 10:21 pm

money is the only reason i cant do anything to my car at the moment, that and id have to do it over a vaction period were i wouldnt need it as much

yeah, $250 is a very rock bottom minimum for a s/c, and you also get what you paid for, for the most part, you buy a $250 s/c it will run like a $250s/c, for that price its most certainly a used one, thats also only small roots blowers

a centrifugal is usualy $1,400-$3,000. and a twin screw is even more, but since your not wanting road ripping power a roots should suit you well as long as you do things like intercool it, unlike some people

asc_up · Post by **asc_up** » Wed Sep 13, 2006 6:40 am

hmmm ok then.
i just need to find a place that could install it and the intercooler.
and where ever i had it installed would probably rip me off anways.

"I just want horsepower to race Hondas"

That just raises red Flags to me, right there. Why would you lower yourself to their level by racing them? Do People know nothing about Subarus? They're not made for drag racing! They are AWD cars...

*sigh*

douglas vincent · Post by **douglas vincent** » Wed Sep 13, 2006 3:53 pm

I race anything!

OF course thats what happens at the drag strip......

free5ty1e · Post by **free5ty1e** » Wed Sep 13, 2006 5:07 pm

Spend the time engineering your own front-mount intercooler setup and piping... spend some time measuring with your front fascia off, get some dimensions and tentative ideas for what to look for, spend some time watching and searching eBay for an appropriate 'cooler, then spend some time behind the counter at a Napa or Pep Boys, looking at the large truck preformed radiator hose, and then get the rest of the bends, straight sections, and couplers bent and cut from exhaust pipe at any muffler / exhaust shop. Yoo can doo eet.

You'd spend mad money paying a professional to fab up some intercooler piping for your car, and for the install.

asc_up · Post by **asc_up** » Wed Sep 13, 2006 8:16 pm

i know that they're awd but it's still fun to race!
so then if i can race and win AND be able to have fun rallying then i'm fine. lol.

i just want the power.

Murphy · Post by **Murphy** » Wed Sep 13, 2006 10:16 pm

yeah getting someone to do that for you would be an insane amount of money, btw how much are you wanting to spend on this?

theres no rallies around here (with in 200miles) and the only tracks in 5 hours driving distance are a series of drag strips, so i wouldnt realy ever race mine, just run it through a corn field, my comp would only be trucks, in town the only comp is hondas, stangs and this one fugly looking eclipse

but i have yet to get a properly working transmission so that wont be anytime soon (if ever)

Check into the front mount from a diesel GMC/Chevy/Isuzu box truck. It looks like a good fit on our cars. I'm hoping the truck at work dies and we get permission to scrap it. I also want the roof vent.

free5ty1e · Post by **free5ty1e** » Thu Sep 14, 2006 4:37 am

That's the one I have on my '94, intercooler from an Izuzu NPR boxtruck, from eBay for like $75 or so shipped. Had to cut some holes in the sheet metal for the inlet / outlet and sawzall the top of the bumper beam off. The IC sits on the bottom of my bumper beam and is mounted by some bent aluminum strips at the top.
