I wouldn't get it.

Sorry guys, I know this is a 'Zu board and all, but c'mon, the 4ZE1 is such a primitive engine...why bother if you have a choice?
Yeah, you can get all sentimental about it an put an AMC head and a Taurus fan and a Ford 3G alt, a cam, some headers, etc.
But, you'll still be seeing nothing but the <img src="/forums/images/graemlins/butwiggle.gif" alt="" /> of any 2G Trooper on the freeway. Of course, the 1G Troops do look better. hmmm...maybe it is worth having that engine...
