I was considering taking plenum, lower and exhaust mans from a junkyard Alero and sending them somewhere like milzy to have them ported. Then, when I rebuild the motor, I can send in the heads for porting and milling.
Edit:
That'll probably be what I do. I know I can expect decent power increases, as a friend from work has a 98 GAGT with the 3100, ans he had his ported, milled and tuned. Says his power jumped up a bit, even with it being NA.
Plus, I think I saw someone in the timeslip thread post their all stock Alero quarter mile, at like 16.9 or so. This makes me feel good, because I think back to a video of a Turbo Civic SI attempting to keep up with a Buick Grand National. The GN gives the Civic a head start and still pulls off a 10.4, but the Civic takes it to (I think) 15.9 or so. Since mine is stock now, it wouldn't fall too far behind.
Here's the video.
