hey guys, if you want to pick up where i left off with this ill chip in. supercharging using the eaton m90 or smaller m62 (both basically stand alone as far as oiling are redily avaiable in the us and i think are close to the one listed) first you need to mount it. easiest scenario i came up with was to make an adapter to mount to the intake manifold to replace the stock crossover tube and hone out the stock tb and make a mounting plate for it on the supercharger. thats step one. i got into this phase and dropped it when my sporty had some issues and i switched to a camaro.
2nd is to reman the crank pulley for the sc belt and a tensioner setup. still relitivly easy with some $$ to a machine shop.
3rd is your fuel setup. look to the 626 or miata for injectors cause the air fed sportage injectors just wont do it. this will take a little modding of the intake and fuel rail.
4th how to manage. basically for piggy back go with the microtec, apexi but i would recomend megasquirt as a stand alone. this way you have total control and monitoring of your system with saving and playback avaialable for troubleshooting and performance enhancing.
the turbo/supercharger debate can be made simple. what type of driving do you do? rally type and on road work best with a turbo. rock crawling and more seriouse off road and sand running go supercharger.
as far as turbo what i came up with is first you need to upgrade the injectors and fuel system. fabbing a turbo manifold is easy as can be and some dsm cars like the talon or eclipse offer a decent turbo with minor takeoff lag that should work nice. i belive its mazda626.com that has a listing of compadable parts.
the things to look around at is heat soak to the intake from the turbo so some moving of wiring is required, also cutting for an intercooler (which i highly recomend to reduce inlet temps and engine killing kr) is needed. 3rd would be to run some form of alky injection. my feel is that with such a small area and low airflow under the hood of a sportage heat soak will help kill your motor. also from what i read in the article -
http://members.aol.com/solomiata/FE3.htmlyou need to drill the block for an oil passage. i was looking into a sandwich adapter to allow for an oil cooler to run as a turbo line.
hope somebody finnaly does it. feel free to ask questions. if i cant ansewer them a freind of mine is running a modded sportage fe3 turbo in his 626 or mx6 i forget which but he runs low 11's in the 1/4r mile on 93 octane pump gas. he should know.
forgot to mention, working the details of a turbo you need to calculate when you want the power. a low rpm will get you some extra tq but will die out abouve 4000. lots of math and reading will help.
