I have an update for Street Mod.

You can no longer just use "any nissan engine" Since the update/backdate revision, the only two engines you could use in the case of our cars would be the KA24DE and the KA24E. You could only upgrade from the E to the DE (Or even downgrade for whatever the reason) But no SR20 because it was not offered stateside in the S chassis and definitely no RB/VQ etc.

An example local to me is a 1986 Prelude running a b16a2 from a 99-00 Civic Si. It was legal until update/backdate because it was a Honda engine. After update/backdate the car became an XP car and was basically useless for anything other than a bunch of fun.

Likewise, putting that same b16a2 into a 96-00 civic ex/dl/lx would be completely legal for SM.
