Hello, I am new to this but I have a plan to turbo my grand prix's 3800 using cartuning.com's turbo kit, I would also like to build my motor in addition to this. My problem is that I am running a bone stock 4t65e transmission and I doubt it would last long with the possibly 300 -400 hp set up I'm hoping for. So I was hoping someone would be able to throw me a list of transmissions that could handle this. Front wheel, rear wheel, automatic, and manual are all fine as long as they bolt to the 3800 (or can be made to). I'm just looking to weigh my options here. Thank you so much for reading and thank you for any suggestions.
