It's definantly not a plug in deal. There is splicing and soldering required. Takes some work and patience (especially your first time). There are tons of write ups on various webpages on the SR install. If I were you I'd start researching and then ask about anything that you question. When you feel confident that you understand how the wiring works then go for it.
The front clips look like they've been sitting in a junkyard. They aern't the prettiest thing in the world. Some importers will clean them up a bit and again some won't. But as long as everything is there works it's all good.
I personally have never done an S14 swap. But Brian (head tech) has. I believe it was an S14 motor into an S14 if I recall correctly. There were a few diferences but nothing major. The car is in Chicago, black S14 owned by a guy named Samad.
Like I said if you are mechanically inclined you can do it yourself. It will take longer but it may be worth it for you. Of course if you take it to a shop it will be in and out and you can enjoy the feeling of roasting hondas like they are nothing (oh wait they are
)
