New to site, just some basic questions.

[BUICKGNMAN87]

I have a bone stock 87 gn that I just purchased. The car is not in good shape, and the motor may as well be dead. The previous owner did NOT know what he had. in fack he stated "I allways felt this car was fast for a buick." he used it as his daily beat up car. I am on a very tight budget, but I bought it. I have allways wanted a GN. I have total respect for those cars.

My questions are:

1. I want to get it back on the road, but the motor is blown. I need a good core to start with. new and used turbo 3.8 are expensive. can I use a none turbo 3.8 and modify it with the turbo motor parts? ie, FI, turbo, heads etc...

2. If so, when I go looking for a 3.8 V6 out of a regal or something, what should I look for? any particular year? Block? car? What do I look for in a good core. I will then ugrade all parts for turbocharging. such as: crank, rods, pistons, cam etc...

3. what does "rolled fillets mean" for the crank

Thanks
