Well I went to the storage place today to take some measurements for my M90 s/c... and took some pics.
The interior is FOR SALE- everything but the dash and dash related parts. All other panels, seats, etc. MUST GO! Make offers, pay shipping.

How in the world do you plan on fitting an M90 in there, let alone get it hooked up to the belt?
Have you got one in hand? If not, I can take some pics/measurements for ya and I can also give you a contact to get them about as cheap as they come? I know HTPerformance had one for sale on here at one point that included the LIM, but the LIM is probably going to be worthless for your application.
That said, that thing can give off a tremendous amount of heat, so keep that in mind. I know where there is a will there is a way, but an M90 is a fairly stout blower and I just cant see how you are going to get that thing in there to say nothing of hood clearance and serviceability. They also use the most foul smelling oil ever know in the history of the world too. That stuff stinks wickedly bad.
Also, if you do get one, make sure the coating on the rotors is in good shape and that the coupler is not toast. In fact, Id get a rebuild kit for them and replace the seals and bearings in the nose drive and the needle bearings in the case, which I can point you to a resource for that as well.
Even if you do manage to get that thing installed you're going to have to deal with the BBV (Boost By-Pass Valve). I believe Jackson Racing uses and M62 for their blower on the SVT which is a smaller blower in physical size.
Im not trying to discourage you, but I think there is a ton of considerations for using a M90 in a Focus. I think you would be better off using either the M62 as Jackson Racing has or using a centrifugal blower. There is also the consideration of using either a Gen III or a Gen V M90. If it were me and I was dead set on using the M90 Id go with the Gen III. Id also have that sucker ported cause outlet temps are going to be a BEAR in that Zetec with the M90. You get those outlet temps too high and you're going to be constantly engaging the knock sensor and you'll loose about 2 - 3 hp for every degree of knock that sensor sees.
Anyway, I'll stop rambling. You can always email me if you need some info.

After many many careful measurements, I have found it will fit JRSC / PWSC style, right on the (custom) intake manifold. I'll need to fab my own manifold, but it'll fit just like a JRSC / PWSC. That's also why I want to run a water-to-air intercooler and an "ice bucket", to keep everything cool.
I have all the dimensions for the M90, as well as the compressor map. I'm doing my homework now to avoid problems later.
It will not be servicable on-car, I'll have to take it off every time I need to work on it, fortunately the M90 requires little servicing. It's going to be packed in there, but it'll fit... barely, but it will.

If you are going M90 Gen 3, then get that thing ported. If you look at the bottom of an M90 you'll see the triangle shaped outlet. The wide end of the triangle is not flush with the case, if you get that machined and made flush it will not only add some power but also reduce your outlet temps.
I would suggest a Gen 5 M90 if it not for the fact there are some differences in the two designs that have to do with the BBV and the PCV systems, but the Gen 5 is already ported and the slots on both sides of the outlet are about half the size of the Gen 3 and because of that the Gen 5 gives of a definately enhanced supercharger sound, much more distinctive than the Gen 3.
Issues to beware of on the Gen 3 are primarily the coupler in the nose drive, they are prone to going bad but the after market ones are rock solid. I installed one on my blower shortly after getting the car. If the coupler is bad there will be play in the nose drive and it will sound like you got pebbles running around in the blower.
The other issue is the coating. On the Gen 3 blowers it is a type of expoxy coating, obvously not epoxy, but similar and it wears off after some time and reduces the sealing in the blower and will reduce boost. You can run the blower without it, just dont expect to see good boost numbers. Then Gen 5 uses a different coating and is much more durable.
Dont ever use any type of cleaner on those Gen 3 rotors. I can use Amsoil Power Foam, GM top clean, Seafoam or anything like that because it will degrade and/or strip the coating.
If you email me I'll give you a couple links to some places you can get some M90's pretty reasonable.

I would email you, but I don't recall your email address, and it won't let me click "email" in your profile.
I was just going to buy a used M90 off a SuperCoupe- you can usually scoop those up on eBay for ~$100. It flows 500cfm @Q 12krpm, and I would assume I could spin it a little higher.
All the ported ones I've seen usually go for $700-1000... sometimes more, and since I am trying to build this "on the cheap" my goal is 300whp with under $3k in mods (since they make 270whp w/ the Powerworks s/c, and that is ~$3k).

Ummm, I dont know where you are looking for your ported blowers at, but I got one in the works for around $200. Mind you, its just the case but you could pick up a used one cheep and just swap out the case. I have attached a picture of what a ported M90 looks like.
Dont quote me, but I dont think they are set up to spin at 12k. Seems I recall reading that around 13k or so was max spin on those things. I believe the GTP is set up to spin at around 10.5k or so, thereabouts, maybe 11k. You'll certainly be able to spin it more than 12k, but depending on the pulley it comes with, I would be skeptical that it spins that high already. Speaking of which, that would be another investment I would make is a modular pulley system. Get the hub pressed on and then you can change out pulleys in about 5 minutes. Well on my car anyway, I would say a bit longer on the Focus. The advantage is that you could run a street pulley and then a smaller one for track nights.
I would say not to expect more than around 50hp from the M90, maybe a little more depending on tune and such, but there are some variables there also such as pulley size, KR, port work, etc. You could be putting out 10psi but if your exhaust cant get rid of it you arent going to get much from it, but Im sure you know that. You'll see less psi the more free flowing things are which is a good thing to an extent.
Anyway my email address is syntheticshield AT cableone DOT net.

The compressor maps I've seen for the M90 put it at 500cfm @ 12k rpm. 500 CFM = ~300hp. -40hp (it takes 40hp to run the compressor at 12k) = 260 + nitrous.
My goal is 300whp, and form my #'s, it's feasable. Since the 500cfm @ 12k was on a stock compressor, I would assume a ported blower would flow even more.
I plan to have headwork, cams, low CR pistons + rods in this motor, so it'll be set up for boost. I'd prefer not to spray to get my 300whp, but I'll do what I need to.
I'll set up for direct port nitrous, as I don't think running the spray through a red-hot supercharger is a good idea

Well what you will need to keep in mind that that power gain is dependent on several things, despite what the mapping indicates.
1. If its a used M90, chances are it is not going to seal perfectly.
2. Outlet temps. The higher they are, the less power not only in terms of overall boost but power lost from KR. Again 2-3hp per degree of KR.
3. Overall efficiency of the M90. This is why the Gen 5 M90 is a popular addon to the GTP. First it is ported to start and secondly it is more efficient over the Gen 3.
4. Drag losses from the bearings, particularly and especially the nose drive bearings. There are some solutions out there to that but they can be pricey.
I dont recall what the stock compression is on the Zetec motor, but anything over 8.5:1 is going to be an issue particularly if outlet temps are not controlled. If you do the blower porting, head work and cams as you mentioned I would assume you would have the outlet temps dealt with sufficiently, though I cant say for sure since I have no experience with blown Zetec engine to draw upon.
Realistically your looking in the area of a 40% increase in power, MAYBE 45% tops. Which on a standard Zetec would amount to about 50hp and still leave you at under 200hp at the crank. Headwork and cams would obviously get you some more but Im not sure they are going to amount to 100 more hp.
I aint saying it isnt possible Im just saying that with my experience with the M90 its going to be tough. Just to illustrate that, the GTP comes from the factory stock with 240hp and 280tq. An N/A Grand Prix GT clocks in at 200hp. Assuming a 40% typical gain for an M90 I should see 280hp at the crank but instead its 240. Granted some is due to lower compression on the GTP but not all of it. Now, my first phase of work on the GTP focused on dealing with KR. Increasing airflow, and exhaust work then getting temperatures down. Even with all of this I still see about 3* of KR at the top of second and Im still running a stock pulley. Its too cold to do the work now, but when I get the Ported LIM and blower on there that will deal with the existing KR and be enough to drop down to the next pulley size. Higher ratio rockers and inlet work will get me to the next stage hopefully.
Again, I aint trying to discourage you, I just think it may require a bit more than you are planning on to get to 300hp. Then once you get that all worked out, you got traction to deal with. If you can hit 1.8 - 2.0 seconds on the 60ft times in even a slightly modified GTP you are doing really good. There is so much low rpm torque that it can be a real chore to control traction. Heck, the first week I was out of the Focus and into the GTP I spent retraining my foot because I was always breaking the tires loose.
I certainly hope you can do it, it would be one bad Focus to say the least. Id even like to meet it at the track when you get it done, it would be interesting to say the least.

Well I am figuring it this way- the JRSC and PWSC are both smaller blowers. JRSC is an M45 and PWSC is an M62. The PWSC kit puts you at 220whp + (251 on the SVT)... so I don't see why a larger blower won't get me more. Larger blower = more boost = more power.
Headwork, cams, free-flowing exhaust, bigger blower. Sounds like a recipie for success to me.

Dont quote me on this but Im almost certain the JRSC 'was' using a M62, so with a M90 you would get 28cu in. more, definately an advantage there. The M62 I do believe was in the area of 7-8psi which is where the M90 is with the 3.8" pulley. Even with a 3.4" pulley most are still doing only about 9psi.
Ive see a few in the 3" to sub 3.0" pulley range and they are in the area of 12psi. Ive seen very few over that point and those usually require extensive modification, not the least of which is a full size intercooler.
Just for comparison, the GPX Grand Prix (http://www.grandprix.net/limited/indexjs.html#gpx), a prototype that was unveild in 97 to show the direction Pontiac was taking the Grand Prix (that was the introduction of the W body wide track, the body style I have). That car was a V6 (3.8L) and the M90 was going to be set with 10psi, functional ram air and an intercooler and would still only be putting 300 hp at the crank. So, take away 2psi, ram air and the intercooler and you're left with what I own now with 240hp at the crank (before I started modifications). Consider the fact that the Focus RS is a turbocharged 4cyl and is only putting down what, 215hp?
The Chevroley Cobalt SS Supercharged is a 2.2L 4cyl with a M62 and its only putting out 205hp at 12psi. Thats only 32hp over the N/A version of the same motor.
I think you can definately get there with an M90 I just feel, from my experience, it will take a little more than anticipated. Now, go with a M112 and you may be on target, but those blowers are less common and probably more expensive. I can say with some confidence that your headwork, cams and exhaust are all going to go to reducing KR rather that bigger peformance gains. You arent going to have the advantage of a Lower Intake Manifold, at least not the style I have that lends itself extremely well to porting due to the space restraints, so you are going to have to work elsewhere to reduce overall temps and the head work, cams, exhaust are going to be dealing with that.
Again, Im not saying it cant be done, there is just a ton of factors involved. I have seen the after affects of several grand prixs that didnt deal with the KR issue and it results in popped pistons and a rebuild.
I hope you get it done, Id love to see a Focus on the street with 300hp, it would an embarassment to even some muscle cars given the weight advantage and the high revving nature of a 4cyl.

I know for a fact the JRSC is an M45. A small blower. Even those are making 40hp > stock (on the Focus). The PWSC is an M62, this I also know for a fact. The M62 is making ~90 hp > stock. I'm just trying to make ~150hp > stock, on high boost.
You have to remember something else I think you're missing. 12psi on a 3.8L is closer to 20psi on a 2.0L engine, because a 3.8L needs more air to feed it than a 2.0L does- nearly twice as much air. Just like if you put the M90 on a 5.0L (and spun it at the same speed) it would produce ~ 8psi.
I plan to run ~8.0:1 compression, which should allow me to run a pretty good amount of boost. And since this is a larger blower, I won't have to spin it as fast to get more boost, meaning more efficient boost (think colder boost).
I do agree, however, 300whp isn't going to be EASY- but I do believe it will be EASIER with an M90 than with a smaller blower. Reason being, I plan to start off at ~ 15psi (about 1.5x what the PWSC puts out) and work my way up. I'm thinking 20psi should get me there. Even if I just leave it at 15psi and spray it to meet my goal- I'll still have one bad-ass Focus.

Okay, you are correct, I stand corrected. It is the M45 on the Zetec and the M62 on the SVT. I still think though, given the Ecotec platform not even putting out 40hp on a 2.2L w/12psi that even with the M90 its gonna be really tough. Furthermore, the smallest pulley you can run on the M90 is in the 2.5 - 2.8" range and if I remember correctly that is spinning that thing near design limits.
As well, with 8.0:1 compression your going to need boost to kick in pretty quickly which is going to require some fanagling of the BBV settings, easy enough though.
Also, spinning the blower slower has little to nothing to do with outlet temps. Outlets are a result of physical laws that if you compress a gas (air being one) temps go up, so your outlet temps are going to be a function of the boost your making. Granted there is a relationship between the spin rate and the boost, but if you spin it at 10k and make 8psi or 14k @ 8psi, the outlet temps are going to be nearly the same.
I dont thing the M90 itself will have any issues with 15psi, that I know of anyway, but there are VERY few in the 3800 arena making that kind of boost with an M90. Anwyone making that kind of boost has either went twin turbo, twin screw blower or centrifugal blower. Theres a whole slew of GTP's in the 12 - 13s ET range, but those going lower are using other F/I options. One of the vendors for aftermarket parts currently holds the 3800 FWD record with a 9.01 @ 150mph but he is twin turboed.
The weak point with runnig that much boost is going to be gaskets. I have a set of replacement gaskets on my desk at home that will allow me to get there, but without them I wouldnt be able to touch 15psi. The LIM gasket would be the first to go since is its a type of plastic from the factory and was not intended for much more than 13psi. So be certain (which Im sure you will be) that your gaskets are going to be able to withstand that kind of pressure.
One thing you can do to keep the temps down is use water/alcohol injection. There are some awesome kits out there, I have a link to one on my business website in fact. I know the guy that sells them and they are outstanding kits. It can be a tad intensive to tune with injection, but it can be done and can offset not having an intercooler. Its very safe overall. Several of the GTP owners are using it and it is extremely popular with the Buick Grand National guys, which also used a 3800 motor.
Anyway, I'll leave it at that. Im anxious to see this done, even more so to run it at the track. It should be something you document extremely well, including research, pictures, everything. It could very well be something you could put a kit together for. There's certainly enough M90's on the market that they can be had pretty cheaply.

You have to remember something else I think you're missing. 12psi on a 3.8L is closer to 20psi on a 2.0L engine, because a 3.8L needs more air to feed it than a 2.0L does- nearly twice as much air. Just like if you put the M90 on a 5.0L (and spun it at the same speed) it would produce ~ 8psi.
I plan to run ~8.0:1 compression, which should allow me to run a pretty good amount of boost. And since this is a larger blower, I won't have to spin it as fast to get more boost, meaning more efficient boost (think colder boost).
I do agree, however, 300whp isn't going to be EASY- but I do believe it will be EASIER with an M90 than with a smaller blower. Reason being, I plan to start off at ~ 15psi (about 1.5x what the PWSC puts out) and work my way up. I'm thinking 20psi should get me there. Even if I just leave it at 15psi and spray it to meet my goal- I'll still have one bad-ass Focus.
