can you even get a roots style supercharger on a straight 4cyl? i thought they only made them for 8cyl engines...

They're mostly seen on v6's & v8 cars, but there are still quite a few 4 cylinder cars with them. Most companies use them on 4 cylinders to retain the 4 cylinder fuel economy, but make the engine accelerate & feel torqey like a v8.

get an eaton m90 or m112 and make a custom intake manifold
|
An m112 is a little big for the 2.3. Honestly the m90 is a little big for it aswell. Both will work, but roots supercharging a car is the same as turboing a car as far as size; you go too big you lose efficiency, you go too small you lose efficiency.
You would probably be better off with an m62 for the 2.3.
You don't need to make a custom intake manifold for it. The only real necessity is that you mount the inlet of the supercharger AFTER the throttle body. You can leave the intake the same, but you'll have to move the tb. & you will have to make a custom bracket, which is cake to make as long as you can weld, cut metal. roots s/c kits are extremely easy to make imo. The hardest part if you're going the junkyard route is finding a crank pulley if you're using two belts (one for accessory, one for the s/c alone) With an m62 you really don't need a separate belt for the s/c as the hp required to drive an m62 isn't too great.
As far as the throttle body you kinda have it made if you're using an m62, generally you can find an m62 with one still bolted to the supercharger case, but you'll have to run a longer throttle cable (I usually just use bicycle brake cable)
Also, you can use a front mount intercooler with one. The deal with that is, the further the throttle plate is away from the engine, the slower the throttle response, but with the supercharger response is still pretty quick even with a fmic plumped in.
