Tons of info on r3v and an e30tech. There's even members on here with build threads. Do a quick search and you won't be disappointed. I'm just finishing up my m52 swap so feel free to PM anytime.
Anything in particular you want to know?
Here's a good place to start. Once you are done that just follow members build threads. Any hiccups along the way are usually solved in the thread and documented.
Hope that helps for now.
