Saw you were running smaller twins on your setup. I am planning on doing the same for my 87 Grand National swap. I'm actually shopping for my engine right now, and I'm leaning towards a 4.8 but it all depends on what kind of deals I can scrounge up. I'm going to search to see if you have a build thread, but I'd really like to know what turbos you're running if you don't mind. Right now I'm looking at twin BW200's, if I remember right I have my choice of 47,50,51, and 56mm comp wheels. They're about $600ish new. I've debated some ebay 3071's or 2871's but when I found out I could snag the Borg Warner units so cheap I've been leaning that direction. This will be a street car and my primary focus is to make the most responsive setup possible. I'm going to put in a decent cam and possibly have whatever heads come on the engine worked over. TSP quoted be a ballpark of $16-1800 for their 2.5 heads and appropriate cam, but I haven't really looked into other options.
