I have a question about supercharging my car.I own a 95 civic dx with the stock d15b7 and I was wanting to put a jackson racing supercharger on it.I was wondering if my stock motor would handle it or would I need to build up my internals first.I also plan to have more mods besides the supercharger.Any help will be appriciated thanks.
Supercharger question?

welcome to the CC site homes and i would recommend u getting the internals done first. but thats just me. just in case ur engine cant take the supercharger. any reason y u want to supercharge and not turbo or use a D series motor and not a B series motor?If you have the money for a JRSC, then you should be able to get a B-series swap done.
If you want to stay with the D-series, then you're much better off with a turbo - cheaper, more power, easier on the engine, etc.
But if you desperately want an SC, you should be ok with the stock engine, just don't upgrade the pully without first building the engine.

I want to stick with the d series just to see what it can do plus its a lightweight engine.As for the supercharger I just want to be different and not have to wait for my turbo to spool.Not like Id be waiting long but still.Thanks for the info and the greeting.
If I was going to do a swap I would put an H22 engine in it.
If you get a properly sized turbo, you will have very little lag. Is it really useful to have boost at 1500 rpm? You should really think about getting a turbo instead, SC's blow 
You could get a lot more out of a turbo than an SC, though. Turbos are more efficient, cheaper.
But if you have your heart set on an SC, JRSC's are designed to be installed on a stock engine, so if you really want it, go for it.

From Jackson Racing site:
What's that I see? A 40 whp gain? And this is the EX, which has 20 more hp to start with than your DX. You'd probably see an extra 30whp max gain...is it really worth it for $2500?
Mr. Lin is right though, you need to research more.

I did my research and basically a supercharger and turbocharger are the same thing they just run off of different things and if you dont believe me go to superchargersonline.com.You get about the same power gain percentage and they both can be intercooled.
You make it sound like we don't know what we're talking about.
Don't get defensive with us.
If you plan to run a supercharger, it had better be at low boost, otherwise, your motor will be s**t in a few weeks/months.

Can a SC and a Turbo be created equally, I'm not really sure. But what I do know what you'll need to do for more power. The SC will require you to upgrade your pully while a Turbo can just be reconfigured. Turbo would be better for changing your boost easily.green dragon said:
Although I think a SC is good for some power as a daily. And since there is no lag, more fun faster
:Tacomasrunner has a SC. It's fun and he's been running it for over a year and no problems, but even he now wants a Turbo. Do more research and find out what you really want from your engine.
If what you really want is a supercharger, then don't let us stop you. I'm sure you'll notice quite a difference no matter which way you choose to go. Nevertheless, a supercharger will never get close to the efficiency of a turbo, it's simply a matter of physics. I have taken the dyno from Jackson Racing's website, and chopped it onto a dyno of another Civic EX running a Greddy turbo kit (non-intercooled). Both setups are running 8 psi, both are tuned with the included electronics. You decide. The thick red line is stock, the black lines are the JRSC, and the green/blue are the turbo. You'll notice that the SC makes about 20 whp more below 2000rpm. At ~3000 rpm, the curves cross, and above the turbo makes more. You'll notice that by redline, the turbo is putting out 40 whp more than the supercharger.
Sorry for the terrible chop, but you get the idea
It's really your call. If you want to be 'different' by getting the sc, then go ahead. But if you are after power, then the turbo will be a better option.

Can't run a header with a turbo. Turbos use turbo manifolds. Take a look at the things that are included with any of the kits out there. You'll need a downpipe, piping for the air, oil lines, injectors, some sort of a/f controller, etc. If you're not gonna do the install yourself, then talk to the shop that will do it. And if you are gonna do it yourself then research some more.jokenfu21 said:
