I have surprised a few in my 2.2j...but they arent fast by any means...the tranny is weak, shifting feels like Im driving with my eyes cloed, the interior is not very durable, they are heavy for what they have under the hood, sluggish. But...1-3 gear ratios are quite aggressive and you give a few people a run for their money. I could hang even with my friends Probe GT 6cly (w/clutch master, fly wheel, pullys, exhaust, and intake) with my stock 2.2J. We raced all the time and we would be dead even until we hit 4th (the top end on the J is rediculously sluggish). I like the way my sunfire looks, its aggressive looking and thats really why I bought it. You always hear the cliche of " the fun is MAKING it fast" and thay may be for gearheads that know how to rebuild engines and stuff like that. I, however, don't know how to do that so making my car fast would cost way too much money for what its worth..so im gettin REX this summer. Also, there is next to 0 aftermarket support for GM J platforms.
