I have a question for you all... I am saving up to get a Lancer OZ, and I was wonder which would give me more horsepower. A turbocharger or a supercharger. I have heard both sides, and I am not sure which is actually better. So if you could help me out I would be most greatful. Thanks alot.

turbo is the only way to go on small four cylinder engines because they don't produce much torqe and the way a turbo works is it uses hot exhaust gases to spin a turbine thousands of rpms that blows air into your engine boosting manifold pressure...I would suggest a intercooler with any turbo config because hot air is used to spin the turbine so hot air is put back into the engine making it run hotter and hampering a bit of its performance. A supercharger is belt driven by the engine its self. It runs off the crank pully and turns another pully on the supercharger which turns the turbine that blows air into your engine. A supercharger you see uses the engines power to run it and on 4c engines you dont have a whole lot of torqe to work with. So basicly turbos give free horsepower so to speak but dont be supprised when the turbo ends up costing a little more time and money than a supercharger will.
good luck!

 

Crotch Rocket makes a good point, but the main point here is... Good luck finding a S/C for the 4g94. Maybe in a year or so, but not yet. There are turbos around now. Have fun with whatever you do, but remember to have patience, when you step away from NA you open up a gigantic can of worms. Don't be too proud to ask for help.

 

Luck may not have anything to do with it. It's entirely possible the SC kits for the 4g93 work with little or no modification. Whould I do it? No. Would it be more beneficial than turbo? Only if you want an even powerband really. It's worth a shot. A lot of people prefer SC to TC anyway so more power to em if they try it out.

 

The supercharger systems are good and when properly designed for a fixed boost level will provide the same horsepower as a turbo system. The side effect is more expensive than a turbo system to setup and deisgn, can not be modified easily and requries bit more work to fit in intercoolers etc.

The benefits are no turbo lag and instant torque from idle up. Doesn't handle ultra high rpm but for everdya driving can be better.

A turbo system when used with an older style turbo like a TD04 etc is cheaper to setup but more laggy and can be sometimes hard to use with a street driven car. This is one of the reasons why the superchargers are so effective compared to older turbo designs.

But when using the new roller ball bearing garret turbo's, they are virtually turbo lag free and do are more linear on the power curves. Cost more than a older TD04 turbo but requrie less oil pressure, last longer and produce more power.

It comes down to your choice of system. At this stage the garret turbo's on a lancer is far better than a supercharger system. That has been our experience on both the lancer 4G94 and the Mirage 4G93 engines.

BEst of all with any turbo system you can leave it as it is or wind the boost up.

Limit your boost to 5 psi and you don't have to have an intercooler. Can setup this as a basic system and then upgrade to an intercooler and higher boost later. All RPW kits can be fitted this way - there is no special ordering requried. To upgrade to a intercooler later is very easy.

ANyway here is a quick explanatin and hopefully answer some of yoru questions.
