I am looking at purchasing an 87 turbo. It was recently painted and had leather put in. A few months ago it blew the head gasket. They replaced it and had the head milled, don't know if they did anything to the block. After that it got a knock in it. I have heard it and it doesn't sound too bad only starts when the engine is reved up. The car comes with a 88 na, the engine is good. I thought about doing a temp swap until I figure out what to do with the 7mgte. The 88 needs body work and new bumpers. The guy only wants $2800 for both. What would ya'll recommend.
