I'm just curious which one is the better choice as far as both performance and reliability. Is it possable to install either one and still keep the car smog legal? I see pics of all your guys engines and I don't see how you can fit all those extra components under the hood and still have room for smog equipment.

 

Like anything with a car, there are ALWAYS compromises!!

I personally like turbos because wasted power out the exhaust can be utilized to make power at the crankshaft.

 

Yeah but is it possable to run either one and still have it smog legal??

 

Don't get me wrong because I have built both turbo and supercharged cars. But, with turbocharging and the fact that there is not currently available a thirdgen turbo "bolt in kit" let alone one that has been emmissions tested, makes it very hard. unless you can not only fabricate your own turbo kit (as many here have), retain all emmissions equipment, and pass the visual, sniffer (probably the easiest part), and give a good arguement to the smog referee you will be sent to, to get certified you could screw yourself. the good news is that companies like procharger and vortech not only have "bolt in kits" for thirdgens, but the have them in verying degrees of smog-legal, and also offer the availability of "bigger" head units that can produce enough boost to turn $20,000 engines to confetti.
