hmm, yea...for engine swap, you are going to have to go for the b-series such as the b18 and b20's. i heard you need custom mounts and only a couple places made em (really hard to find)... i thought the LX-i was around 120?...sine it was fuel injected and the others were carbed?
as for the JDM shit, good lck with that, i havent seen much aftermarket exterior parts other than liek the basic clear corner or bumper lights.
suspension will probably be one of the easiest, DC sport only make the 3rd gen strut bar, otherwise, u'll hgave to modifiy it from a 4th gen strut bar.
