m90 supercharger, gm on 2.2L
Tuesday, July 11, 2006 7:37 PM
Ok so I'm on a mission, i bought a m90 for cheap and I will get it mounted to the 2.2 in the 95.

Now to give you an idea of m90 in compairison, its the size of the head, and the pully is about as big as the waterpump but is the same type as the Alternator.

So here's the plan, mount it where the normal intake is now, but chop up a stock intake and make/weld it to the supercharger. The SC will sit lower on the back of the engine because of the brake pressure cylinder is in the way of the intake, and b4 the intake there is just enough room to run an intake pipe between the break/fender to FMIC.

I thought about locating the SC up front, but the issue then arrises because of heat off the exhaust manifold. It will fit, but awefully close to the exhaust manifold.

Any one have any other ideas besides "it wont work" or your "crazy". I've already heard that from most the novices. All the machine shop guys say, it should work it's just a matter of integrating into the header setup.

If anybody is currious this SC originally came with a MAF, and it's still mounted, but i doubt i will be using it as my J pcm is map.

so you want to mount it to the Intake manifold, then run it through a FMIC, and back to the Throttle body??

how would it work, but it matters of intergrating it into the "header" set-up??

do you even know how un effeicent the blower is going to be on the 2.2? do you know how much boost its going to be pushing? how about the rpm?

its not as easy as bolting any supercharger onto motor.

p.s all j's pcms are map.. not just yours

Actually i got an idea, with the stock pully it will boost around 7psi.

The m90 is the charger used on the 3800 SSEi's and while it's efficiency for a v6 isnt the top it should be fine for my application. The car is more of a show queen, though it does see some tracks. I'm only looking for mid 14's, and i've seen a blown 2.2L with an m90 do better.

I can integrate it into the intake mani setup, but i will have to build a custom fuel rail with top feeds to make it work, it should work and if it doesnt do much, well then lesson learned.

Where did you see a 2.2 with an M90? I'd love to see some info on that if you could find a link or some pics.


15.3 @ 89.97mph, 14's on the way?

the efficiency of it is going to be no where near what your probably expecting. There is a reason GM uses the m45 on the 2.4l twin cam and a m62 on the ecotec
How are you controlling fuel? how about timing? what happened to your FMIC idea? What are you going to do for a belt? how about brackets? all custom obviously, but now your cheap supercharger just turned into a huge expense
all i can say is i'll believe it when i see it.

No offense, but people post stuff like this all the time and only 5% (maybe less) of the people actually do what they are say they're going to. I expect most of your replies to reflect that. It's not that anybody is against you, it's that odds just aren't in your favor, but prove me wrong.

That said, Your choice of blowers may not be the most logical as the flow rates aren't going to match very well. There is no point in adding a FMIC because the temperatures wont grow as high with your engine operating on the lower end of the charger's efficiency. You are going to run into problems with actually lining up the pulleys making the intake manifold. Make sure you brace it as well or your manifold may crack with the constant belt pressure plus vibrations.

Well sorry to say but now you are hearing it from one of the veterans. Sure you can make anything "work" but how well will it really work and is it worth it. Even if you could fab up something to make it work the M90 is way too big for a stock 2.2. And if your machine shop guys are saying to integrate it into your header you should really think about bringing it somewhere else, lol. Also what are you going to do about the TB? What about the BBV? How about the wiring and the PCM? I don't really want you to answer those questions I just just pointing out that this will be a huge headache and probably not worth the time or money. And you say you have seen an M90 installed on a 2.2 before? I would love to see the pics of that. By the way did you know that it takes about 80hp from the crank just to spin the M90 at 6000rpm. I think any additional power you would make will be eaten up by spinning the SC and if you get past that then I don't think the internals will last very long.

But hey, don't get me wrong. If you want to do it go for it but my opinion is it would be a waste of time and money.

An M90 really is too big. If you go with it anyway Minion was right it will be operating at the lower end of its potential. The higher you get to the peak potential by spinning it faster the more heat. An itercooler is simply not needed. If you did use one you would hurt your performance because you would have to produce boost through the entire lenght of piping plus the FMIC. Getting it to line up is going to be a nightmare. Also you need to route the belt so it spins all acesories and the supercharger in the correct direction. Bracing it will require alot of time to construct and design a brace that probably will not be sturdy enough in the first place. Not to mention all that custom fab will probably not look good in a show car. Have you seen al the braces in the GM 2.4 kit? Have you ever installed one? I know you have not because otherwise you would fully realize what you are up against. On top of all that you have to figure out your entire fuel sytem (injector size, fuel rail, fuel presure, upgraded fuel pump. Then you need a diferent map senor. You also have to figure out your igniton timing, and spark plugs to use. If all you want in the end is 14 sec 1/4 mile just buy a turbo kit.
