Along the lines of this dreamer thread (super/turbo charge I5)....... How about installing two in tandem LLR 3.7L I5s?? 10 cylinders!

If you can't live with a modded I5 = Intake, PCM tune, Efan, PP TB, cat back exhaust, and even a header............ That is why GM made the LH8 Alpha.

I like the H3 enough to invest in aesthetic mods, but having to drive the I-5 every day is borderline intolerable. At this point, though, it's a sunk cost... unless anybody wants to trade me their Alpha.
