I was wondering if anyone had a complete list of what it would take to put a turbo on a grand Prix with a 3.4L. And if anyone knows how to get the engine back to the original 300 hp that it was originally intended to have. Would if be better to do that then the turbo or one or the other. And what will a stock 4T60-E withstand up to. Id like to reprogram it to have the 300. But it would be cool to have one with a turbo too. Also if I were to do either or. What hard parts or rebuild kits would I need to strengthen the tranny. I would like a complete list as I am new to the turbo and transmission rebuilding.
