I read a couple months ago about not being able to put a truck engine into a passenger car on the DMV website. I'm with you zgeezer, I'm droping in an LQ4 into my Z32. If I could get it legal I would try to get it legal, but, I don't even have a chance. I guess I gotta pay off the smog station to see a VG30DE under the hood and pray a cop doesn't see under my hood.....
