I am doing some research on supechargers and turbochargers and was wondering some things.

I would imagine that the Ecotec motor must be upgraded slightly in order to handle a supercharger or turbocharger.

Am I right when I say the pistons, crankshaft, valves, rods, and tranny would all have to ne upgraded? Along with that I would imagine an upgraded fual system with high end injectors need to be installed.

But how about an upgraded fuel pump? Would this be necessary?

Thanks for the input.

from what ive heard you also need to add a minimum of 92 (i think its 92 or 97) fuel to that list...

stock the ecotec engine and car should be fine with up to 6-7 PSI of boost with either a supercharger or a turbo. If you want to go higher than that, then i would go with what your talking about.

the fuel pump might not be nessacery, you can alter the fuel pressure by decompressing the spring in the fuel pressure regulator, its a tricky little job, but it works, you can also buy an aftermarket one.. as if you didnt know that allready

Having the crank tuftrided or nitrided would only be necessary if you wre running about 20 psi or over. You may need s/steel or brass valves and stiffer valve springs with uprated retainers. If you were running lots of boost I would upgrade the fuel pump. just as a measure to prevent detonation, also Big Dude 1 was right about the fuel, use as high and octane amount as you can but 91/92 would be fine as it will prevent knock or detonation. Don't listen to people who say that higher octane fuel leaves more carbon in you engine as this isn't true. The argument is that it burns cooler and cant burn off the Carbon. Carbon is a result of the combustion and comes from impurities in the fuel which a lower octane fuel has more of. Higher octane fule is better quality as when fuel is refined it come out in layers and the higher the octane the further up it comes from and is 'more refined' but the higher the octane to make the same amount as a lower octane fuel you need more crude oil, hence the price difference!

How much boost are you planning on running. A stock eco with fuel mods can handle about 6 psi, but I wouldnt use boost without a built engine. Boost is addictive and Im sure you will want to turn it up.

Just like Bass when you get those new subwoofers... "BOOM BOOM BOOM BOOM"
