Does anyone know if it is possible to supercharge *or turbo* a carburated 4 cylinder 2.0L? If anyone knows anything on this subject, please let me know. Thanks

Yep- Can be done and I have done it a few times...

You run into the same design flaws with the engine as with Turbo- basically boost is limited by what can be kept in the chambers without leaking by the heads..
do some searches- The search function is your friend!

In two weeks I plan on *MELTING* 3 engines under boost on the dyno as I kick off a solid year of Turbo R&D!

So what's involved in setting up a supercharger? I'm trying to find out as much as I can to make it all the easier, since I now know it's possible. Let me know. Thanks

Hmmn, Do you have access to a machine shop? welding equipment?

If not you might wanna reconsider- nothing is off the shelf when doing this....

The Supercharger I have used a couple of times is from a Ford Thunderbird called Eaton M-62

Its far from a bolt on affair.

Yeah I figured it wasn't going to be an easy process. As far as a machine shop and welding equipment, my dad has a friend that mentioned he had some machining equipment. Still haven't gotten around to seeing what he actually has. I'll have to do that now, since I really have a need to. I'm not sure if this kind of thing could be explained over the internet, but like I said, I'm trying to make it as easy as possible to get this set up going and hopefully working sometime later on. Again, any help is very helpful. Thanks

*do you have any pics of a currently supercharged 914 motor?*

1st thing to do is "remove" carburator from your vocabulary (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

I know pictures have been posted before, yet no luck in finding them....I guess best bet is to close your eyes and picture this supercharger sitting on top of the motor...the belt would be driven off a pulley that is in between the fan and the motor....there was a company in FL many, many years ago that installed a supercharger and might have made a kit, but I have never seen anything about it except some really poor pictures printed in VW & Porsche magazine 20 years ago.

Best bet it spend $23 for SUPERCHARGED, by Corky Bell available at amazon.com

This was covered not too long ago (April 05). Search 'supercharger'. I posted part of the VW & Porsche magazine article and pics of the supercharger install. It looks like the supercharger w/ carb would be easier to do than a turbo, since you could use a single Holley carb and manifold set up and slide a supercharger in between the carb and manifold. The motor in the article was substantially beefed up to handle the extra stress of boost. Putting it together is one thing, KEEPING it together is another...

With the rights thoughts and components it will stay together... But its not cheap!

Don't expect to bolt it on and be happy the first time around- Not for the faint of heart or slim wallet-

Last one. If anyone knows where these came from please enlighten me. (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif)

I wish I had more, esp. since I don't know anything specific about the pictured engines

I like the one with the progressive carb! Hell that carb won't even flow 175 CFM- Its not even enough for a stock 2 liter N/A engine!

have used the toyota inline 6 supercharger (soarer , its bigger than the corolla) they have a clutch on the front and run a mulit rib belt, a mate has one on his buick v6 and my god its fun, we also put one on a 12a rotary with a side draft webber ,had the charger mounted so the flow ran across instead of down this also ran very well

My thoughts were to machine a plenum out of aluminum block and mount the MB Kompressor Supercharger on it, stock plenum runners and a DCOE off the intake side of the supercharger.

Alas, no longer have access to a mill........


Just a dream though

So it seems like this is a lot easier with a single carb? I'm running dual 40's right now. Hmm I guess this is gonna be a long time project to try out hehe.

NO CARBURETOR(s)....period !!!!! (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

If you are going to spend the time, money and effort, use programmable electronic fuel injection.....PEFI can be built for less than $500...you can sell your carbs for that amount or even more..........

Fuel injection is the way to go if your doing this. BTW... Dual carbs would be like putting salt on the wound because of the added complexity...
