Have you ever seen a big block in one of these cars? Turboed or not. See if you can find one and get some pictures, it could help make your discision on using a big block or small block. On mine i'm having to relocate the battery so i have a place to put the turbo. And having a 5 inch exhaust coming off the turbo makes mine just another thing you have to make room for. Try and make a plan and stick to it, are you going to intercool? If yes , are you going to have one or two. Is this a street car or track? If street do you want air conditioning? Specialty Products Design has a lot of big block flanges for making headers, tubing, j-bends,u-bends and turbo flanges. On another note i talked to you awhile back about your TA-60, i ended up with a TA-61. Now it looks like i have to get a new trans and a little stall.
