Unless you tune the zetec to run at high rpms it might not be the most effective power upgrade. Bwaaa, you're kidding, right? Useless? Sheesh. If a turbo requires high-rpms, why would 18 wheelers, that have a redline of 2500rpm, have a HUMONGOUS turbo? I'm no turbo expert, but as long as the motor puts out enough exhaust gases to spool the turbo fast enough, it will make power. Almost any motor is capable of doing this. The more gas the motor puts out, the more power. This is SCA's dyno of their turbo for the Zetec: http://www.scracing.net/dyno-sca.jpg Sure it's not worth the effort? With the turbo already making power on a Zetec at say 3k rpm, you'll have 3500rpm to go to redline where the turbo is producing power. And with today's technology, I.E. Aerocharger's turbo using variable geometry vanes which just about eliminate turbo lag, it's a worthy upgrade. So, instead of spewing useless banter, do some reading up. John

Unless you tune the zetec to run at high rpms it might not be the most effective power upgrade. are you on crack???????? Do you know anything about turbochargers at all????? JVT's post above is pretty much right on, but if you care to debate the finer points of turbomachinery, even as it directly applies to Ford's 2.0L Zetec engine, myself or several others on this board that are knowledgable on the subject would be more than happy to beat you around the head, chest, neck and face with the truth about turbocharging. But if you wish, carry on with your use of the "SpiralMax" (tm) for your low-end power increases. Okay, I might be being a bit harsh, but when people try to spout of information like they know what they are talking about, when in fact they are so full of it, their eyes are brown, it really really bothers me. (yes, that sentance is in the running for the world's longest run-on.)

If your zetec has the same exhaust output of a turbo-diesel, you've got problems. A diesel engine has way more exhaust output than a comparable gasoline engine. With a gas engine you would need higher exhaust output which would make u fail emmission tests. Why would you turbo charge an engine originally designed to be an economical engine? VCT is designed to give you the most economical gas mileage. You're zetec has more low end torque (low rpms) so you're engine will have a great deal of turbo lag. If you wanna turbo charge your zetec... shorten your piston rods, bore out ur cylinder and program ur chip for high rpms. Then save up for a new transmission.

True, but I was replying to your first idiotic comment when you said you need HIGH RPMs for the turbo to be even functional. With a gas engine you would need higher exhaust output which would make u fail emmission tests. Come again? Why would you turbo charge an engine originally designed to be an economical engine? WTF does that have to do with it? You don't put a turbo on a car to be more economical, you put a turbo on the car because you want more power. Not one factory engine is DESIGNED to be turbocharged by an aftermarket supplier, so that's a moot point. You're zetec has more low end torque (low rpms) so you're engine will have a great deal of turbo lag. OMG. So you think turbo lag is ONLY affected by you having low-end torque? I won't even bother to comment on this. You're a moron. What about turbo size? What about the vane design and geometry inside the turbo? Please, I beg you, don't make yourself look any more stupid than you have already done. Really, I don't care about that, I care more of the fact that you're spewing ridiculously false banter on the forums for others to read. Again, I'm far from a being a turbo expert, I have the basics covered. John

Sweet Christ on a cracker dude, you got it all wrong! All the "knowledge" you have about engines/cars/turbochargers/superchargers, you got lied to, and hard! Take a few weeks to look around the internet and maybe a library. Start with an encyclopedia, under "E" for engine. Then, work your way up to "T" for turbocharger. Great Jehosephat!

I have to agree with Chris... you need to go to the library and do some research or stop listening to the people feeding you this stuff...

again, I restate my question: are you on crack?!?!?!?!
jaxcontour, everything you profess to know is wrong, flat wrong. Anything you get right can be attributed to the "shotgun at the side of a barn" effect, if you throw enough stuff out there, you are bound to be close to correct w/ one little tidbit.
anyone who listens to jaxcontour about engine related issues deserves to be stuck driving an F350 towing a heavy trailer, but only powered by a stock zetec.
