1. You can sneak a car in and register it as an S14. This is only somewhat illegal, but will get it on the road in FL. It's just as legal as all of these illegal, non-motorex Skylines running around. Technically the car will be impounded and crushed if caught by DOT/Homeland. It's a rare occurance, but definitely happens. There are *ahem* importers around here, Orlando, Miami that will do this and get you a title/registration. This is the cheap way.

2. Buy a Kaizo recertified, rebranded unibody/roller. This is 100% Fed and State legal. Your title will say Kaizo S15 Silvia. It's quite pricey and it does not come with a motor or trans.
