Actually it's not really a problem, just one the tuners don't want to tackle. ASP Racing makes S/C pulleys for the Eaton M90 in the GM s/c cars and those pulleys are also pressed on. They sell a pulley extractor/inserter. Someone with the resources (mostly time and an '03 coupe) should call Lee and discuss the possibilty and what it takes to get started. Here's a pic of their pulley puller. Here's a website that sells the ASP pulley and rents the extractor. This may be the best way to tackle the problem.

Remember, you only have to reduce it 10-20% to get desired results. So if the pulley is 3 1/2" for example, reducing it to 2.8" would give you 20% more boost, more than a crank pulley currently. Look at the s/c pulleys from ASP for the Ford Lightning with the Eaton s/c. ASP sells a 2.8" pulley and that's for a 13 second pickup truck. We are only hoping for a 15 second little car. Don't believe the hype from tuners, talk to a real pulley company. I think this would be a great opportunity to design a new fresh idea for the 1.8. I think it can not only be made but be produced and sold for under $100 with no belt change.

Ive held many different types of bearings in my hands, they are heavy, and the individual rollers themselves are rather dense as well...certainly doesn't feel or look like aluminum.
The engine bearings arent that type. Engine bearings look like a ring of metal that's been cut in half to form two semi-circles. They really only act as bushings when the engine is starting. After that, the shaft journal rides on a thin film of oil.

I knew I wasn't loosing my mind. I did say
Ive seen bearings with aluminum bearing *cages*, heck even plastic ones, but Ive never seen an actual aluminum roller, ball, or pin.
I'm not a total idiot.

You guys are talking about the connecting rod "bearings" on the crank journals, right? Yeah, those aren't much removed from bushings...why they call them bearings is beyond me. The Oil pressure is the only thing keeping them alive. When I read DCX's post I though, what, is he on crack? An aluminum roller? C'mon, that won't last 100 miles

Um, yeah...Honda *Leafblower* maybe.
Not trying to flame you or anything, but C'mon, bearings made of aluminum? No way. Certainly not main bearings, the aluminum would deform under the weight of the crankshaft and flywheel alone. Ive seen bearings with aluminum bearing *cages*, heck even plastic ones, but Ive never seen an actual aluminum roller, ball, or pin. Same goes for lead...have you ever used lead? Its limper than a wet noodle. The bearings are steel.

However, much of my engine experience is with Harley's, which use roller bearings for the "main bearings", as well as on the crankpin. And those are high carbon steel, with an RC of at least 50 or 60...so please understand my natural reaction to your post about the bearings being aluminum
Ive worked on plenty of car motors, but not anytime recently, so I apologize for the knee-jerk reaction
Thanks for the links, I knew they started with a "B", but its been so long I forgot the term

Supercharger (blower)
If you go to Eaton's web site you will find that they DO make the supercharger for MB and have since the getgo.
The beauty of it is that unlike a turbo which uses engine oil for lub the supercharger has it's own oil. Eaton claims a work cycle of at least 100,000 miles for there units. The other benefits over a turbo I'm sure are already known by most of those on this forum.

Here is quick pic
The issue here is the design of the pulley, notice it is recessed over the nose of the supercharger. those bastids!
Also I don't think they gave us a threaded hole in the end of the shaft for an installer, which makes a bit more inconvenient.
If I were a conspiracy nut I'd say they did it on purpose :p

Don't panic yet dynodog, it's not the end of the world as you know it. The s/c pulley is pressed on as in many applications like the Ford Lightning and the Pontiac GTP, no biggy, you just need the right tool to remove it. Talk to Lee at ASPRacing.com, that's what they do and they have and can sell you the tool you need to do this. There are some ASP dealers that can rent you the tool.

No panic here, I can make the tools myself and the pulley for that matter. My car is a daily driver, may not even modify it, modification is low on my priority list at the moment.
I put it out here for yourself and others to see the design constraints which will make it difficult
Given that a smaller blower is being driven harder than the modified 2.3 L, a better intercooler (or misting) may very well be the best first step with the 1.8L anyway.
Of course, I am disappointed with stock power level for the $$ this car cost...but I knew that going in.
If I want a kick I take out my 7 second R.E.D. or my 10 second 69 GTO
