If I remember right, they're top feed, you'd have to get a top feed rail in order to run them, and check the sizes, you dont want to run 2 different sized injectors in your new top feed rail.

The FD model (93-98) are side feed. The primary injectors are 550cc and have purple tops. The secondary injectors are 850cc with brown tops. You may need new plugs and different sized O-rings.

the 850's should fit without leaking, or at least with some different O rings you should be able to make them work. I had a set but I sold them because there is nothing on the market really capable of controlling them accurately short of a standalone (and they were hella overkill for me anyway). the 550's, however, require some little adaptor flange. if you run a search there have been like 5 or 6 threads about this, and I'm pretty sure a yahoo or google search will turn up the information as well. I think the "collars" as the adaptors are called, are manufactured by a japanese company called "D-Speed."
