I have heard talks of an adapter plate, but that would have to be custom machined and would be more $$$ then i think you would want to put forth, i too am a fan of the supercharger, but www.gude.com makes a turbocharger that will fit the 2.0...hope that helps
I can't speak to the fitment of the JRSC but it's seriously weak and even if you could fit it, it ain't worth the effort. A properly sized turbo at similar boost settings will kill the SC in booth spool and TQ.
Gude has a crap rep in the Zetec turbo world. The kit itself may be a decent hardware kit but it has no tuning to speak of and many Foci have blown their engines running it like Gude recommended.
The Vortech, MIGHT fit. It bolts over the exhaust manifold not the intake so it's POSSIBLE it could be made to fit, easier than the JRSC. That's ultimatley theoritical though. The only proven turbo builder for the Zetec is Turbo Tom at focus-power.com. He's looking for a Cougar zetec to prototype the Cougar turbo kit. Look a few threads down.
There's a few fitment issues, the biggest of which is between the back of the block and the firewall. The JRSC was made to fit in the space between the Focus block and their firewall, and there's about 6 more inches in the Focus than our car. I test fit one, but got so frustrated trying to physically make it work I didn't even bother tying to finish.
Gude - no dice. I've not heard good things about them - thier rep on the Focus and Escort forums is :thumbsdn:. It's not a Cougar kit, though they do have a ZX2 and ZX3 that could be made to fit.
If it's really urgent and important, follow the lead of Seawulf and Afterhours and build your own (that's what I'm doing). Tom Lespereance (TurboTom) is starting to work on the Cougar Zetec, so if you can wait for that, it'll get you the most bang for your buck in the FI world.
When it comes to superchargers, you will see as much or more power from a turbo as opposed to the current "bolt-on" SCs for the Zetec. And while a SC could give you more initial boost sooner than a turbo, a turbo will give you full boost before a SC will. For example, a 03 Cobra(granted a totally different car, but the principle is the same) will do 7psi by 2250rpms and 9psi around 5000rpms. I get 7psi at 2500rpms and 9psi at 2800rpms. The spool on a I4 SC isn't that great when the base JRSC kit only puts out 5psi at near the redline and will give you 30-40wtq less than a turbo that gives you full boost before 3000rpms.
The only place that the SC has an advantage over a turbo is it's more CARB friendly, as it doesn't change any emissions components and most turbo kits eliminate the stock cat. So if you live in an area that has a lot of emissions [censored]'s the SC will be easier to pass inspection. And again, none of the SC kits for the Focus are direct bolt ons for our Zetecs. Though it is possible the new Vortech kit can be made to fit easier than the JR kit. It would also give you more power than the JR and has easier options to intercool than the JR. But for the price of that you could do your own homemade turbo kit and make more HP and TQ.
No. Seriously, I don't want to be a dick, but before doing my turbo I had zero turbo knowledge, I then spent months researching turbo's on the web, especially custum setups. I spent weeks reading the Focus forums, the Focus zetec is internally the same as ours so lots of the principles of turboing that engine will apply to ours, and saw what they were doing. Granted, my dad did built my first setup and while he is a mechanic with over 25+yrs experience he'd never worked with a turbo before, he just read up on them using the information I researched.
Here's some links that are required reading. First, do a search of my past posts using my username and read everything I've posted relating to my turbo setup. Also do a search for Afterhours, he's also just done a homemade turbo setup. Then check these links out.
One of the legends of turbo Dodge cars. He's got a lot of low buck how-to's on his site and good general info. Unfortunately he passed away a little while back, but the site is still there. This sight is where I chose my muffler.
A real important page with lots of good tech, including how to make a turbo manifold on the cheap. That page was probably the single most important resource I found. This website sells their own standalone engine managment, but it's real hard to install and wouldn't be good for a street car, but again the technical info is real good.
This is a how-to on making a twin turbo setup on a Mustang. This was also a real important resource for us and even though it's for a V8, the principals still apply for any engine. This ties the link above for most important resource I found. It shows you how to do it on the cheap and that's how I did it, ordering everything though Ebay or junkyards, or Napa or making what was needed.
And finally my webspace with pics of my setup and a general description of what we did. Once you've absorebed everything here you almost wouldn't need any help, but either me or Afterhours will answer any specific questions you have.
