Your 95 SC2 is sitting in my garage. I want it to go to a good home, not to some 16 yr old to crash and then not have the 20yr old airbag not deploy
Suspension mods are pretty thin so you'd have to improvise, but if the frame bolts up w a bit of shaving, sounds doable
As for the S3, just don't pitch it to GM and you have a chance. And you can make it stand out in a crowd.

Well okay, but you gotta promise each of us a percentage of the earnings from the car...(looks for sketch pad)
I kinda got bored the other night, and finished my S series design, as well as a larger L series(dimensionally placed squarely within the mid size segment) and a two seat RedLine coupe, using a bespoke version of the S series engine with a 9,000 RPM redline...

This talk about an updated design for the S series echoes many of the thoughts I've had since I started owning one. I mean, from a physical size and general appearance standpoint it fits in the same class as the Ford Escort series right before it was dropped. I've driven both and there seems to me to be quite a difference in handling and go power. My SW2 never ceases to amaze me with how much get up and go it has for something with a sub 2 liter engine that can carry 5 passengers. My Geo Metro can get marginally better mileage (it's an auto) but is a total wimp on the road. In fact, I've toyed with the idea of putting the 1.9 in the Metro but I would need to have yet another vehicle available to use while that was going on. The S series is just so lightweight for its size and the 1.9 DOHC is an excellent engine IMHO. A turbo would make this engine even better for power output but I wonder how it would affect the gas mileage. As long as it wasn't constantly driven full out it may not be a significant loss. Having the extra horses would always be appreciated when trying to merge with traffic during rush hour around here.

Actually a turbo might help with fuel mileage, since the engine wouldn't be working as hard and revs would be lower during merging/passing maneuvers... My supercharged ION can generate enough power/torque to climb steep hills without losing speed, in 5th gear, as low as 22-2300 RPM, because it's eating 7-8psi of boost... I imagine that a turbo s series with a manual trans could go around just about everywhere in 5th gear, as long as the turbo would spool up at a low enough RPM... The reason my ION sucks fuel like it does is that with such a tiny pulley on the blower, it takes considerable power to spin the blower while it is making boost...

Actually, none of those factors were present in my argument against the efficiency of the supercharger... Any time the bypass valve is closed, the blower is forcing air into the engine, and making boost... The amount of boost is largely determined by the volume of the blower(roughly half the volume of the engine in my case) and blower speed, in relation to engine speed... In short, I've always been able to make boost at low RPM, before getting tuned, and before my bypass mod... AND with the way the bypass valve works(not relative to the bypass mod) it closes long before engine vacuum reaches near zero(as in a WOT condition), so I make boost at part throttle, at low RPM...
Keep these data points in mind-
Speed-90km/h(~55mph)
RPM- ~2200
(The above were read from the gauge cluster, not the UG, so there is a little error I'm sure)
TPS percent- 58.4%
Boost- 5.9psi
The above was taken while climbing the last major hill between my house and Glenville(on US 33)... I can climb it in 5th gear, and not lose speed, and not needing to go WOT...
I do agree however, that keeping the bypass mod in place is tempting fate for something horrible to happen to some part of my drivetrain... There are several instances in which the ECU pulls boost:
Engine temp above acceptable range
Spark knock detected
Sensor malfunction
During gear changes
At launch(though ZZP defeated this one in the tune)
At maximum boost limit
The ECU can only safeguard the car against abuse under these conditions if the solenoid is active and connected... By disconnecting the sensor, I have allowed higher than anticipated boost levels(I've seen as high as 17.5psi) and prevented the ECU from pulling boost when it detects detonation(which I can't detect until it's too late) or under an overheat condition(which I can detect by looking at UG)... So, I try to be alert when the throttle is pinned, and always keep 92 or better in the tank, shift carefully(and always with the clutch disengaged), and pray nothing breaks while I'm playing...

Are we terribly worried about mileage?
Let's build the monster, THEN tame it a bit
