for the supercharged fc's out there..
I have an 88 n/a, full RB exhuast (headers back) and a full custom CAI. Now my question is, when it comes to slapping on a supercharger what is the next best step after the exhuast and CAI. I dont want to have to go thru the troubles of upgrading for a turbo. I'm not a wiz when it comes to these engines thats why I'm asking. Porting, ECU? let me know, thanks.

well the super charger has more limits and to get decent power you would have to get the carb set up because the FI sc is expensive and dosent make **** for power. i would go turbo, plus i heard the sc's have a lot of defects(not sure if its ture, i think it was only one brand did.)

I did a little number crunching a while ago and found an Eaton M90 S/C will provide around 260 rwhp, assuming an IAT of about 130*F which means intercooling and possibly water injection are necessary.
This would also be on a standalone, however you may be able to pull it off with an safc or similar, just expect about 20 rwhp less.
Assuming electronics are taken care of, it should cost around $800.
The secondary injectors being around $150, S/C should be less than $150, and intercooler and piping< $250, misc. brackets, feed piping, and other such items would take the remainder of the money. This setup will have basically no lag whatsoever.
Now comparing this to a turbo setup, a cheap manifold is $175, internally gated H1E holset turbo is around $400, IC with pipng $250, BOV $20 for a stock DSM one, injectors $150, a turbo adapter is around $80, oil lines $100, other misc items $200. Thats about $1400 for a turbo setup. This setup is good for around 350-400 though it will have appreciable lag.

where can you find a supercharger for 800.00?
All the ones I've seen for FC's are useless pretty much. 3k for a supercharger, when you can buy a jspec TII and rebuild it for less than that.

i have to agree with these guys.I was originally gonna go the sc/na route,but if you crunch the numbers,youget way more bang from the buck by going turbo.My whole swap to t2 cost 3k,including a haltech and drivetrain changes,i am now making about 350whp,whereas a supercharger alone wil probably cost close to that by the time you get it working and will only get you to maybe 250.

Neither adding a turbocharger or supercharger to the NA FC is a matter of "slapping it on". A search on "supercharger" will turn up plenty of project threads. I think one or two was actually completed.

Aaron Cake is right, each project requires making modifications to the car that it was never designed to operate with. Tons of people ask these questions and I'm willing to bet the percentage of the people that actually ask and complete or even start, doesn't even make double digits.
Not to say it's impossible, its quite possible, although it requires research and mechanical ability to make it work.
Consider yourself lucky though, you have a forum that has tons of FREE information on virtually every aspect of your car, and people that would be willing to lend their advice for free, that is one hell of a resource.

One of the baddest FC's on an Autocross I've seen was a SC FC. It pulled like no ones business. The owner has never taken it to the dragstrip, but I'm guessing it's nothing that impressive. Low 13's maybe hihgh 12's. NO serious top end. I've never seen an FC pull out of a corner that hard.

I have one sitting in my storage that I got for $150 with a short snout, and 6 360 cc injectors w/ clips.
A little while ago I found a Millenia s supercharger for $100 shipped on eBay.
You aren't going to find the cheapest way to do anything in a kit, you have to piece it together. For example, a rebuild kit costs around $800, but you can piece it together for around $500.
One example of a completed supercharger project is Zbrown. While it was a fairly slapped together setup, it produced decent results for the money invested.

spch's are a waste of time and money, you could get a turbo motor with that kind of money.plus you can leave your na tranny in with the turbo motor, unless you want more power..then change the drive train

You can find an M90 for next to nothing. go to Clubgp.com and you can find them all over th eplace from GTP guys going turbo or upgrading to the gen V M90.

Where do you com up with your info? If you can make power on a carb setup then you can make just as much power, with better driveability, with an standalone setup.

Why? If anything, a screw is the best. A roots is only efficient below about 8 psi, then a screw is more efficient. A cent. type has most of the lag of a turbo, without having the benefits of easily increased boost.
