I recently purchased a D1sc from a friend of mine and I am pretty sure that it has the standard 3 core intercooler that they usually come with. My question is will this suit my application ( I am planning on 500-600hp at the wheels) or should I sell it and get the 3 core sheet metal intercooler. And how much will I end up paying for the 3 core sheet metal intercooler? BTW my car is a 91 coupe. Thanks in advance.
