Hi this is my first time posting a thread and was curious, Is it possible and if it is what are my options. I have a 2001 Honda Accord v6 and was wondering if there was any kind of engine I could swap while else keeping the car automatic and how much would it be estimated to be?
Unless you're looking to spend a ton of money on a completely custom swap, your options are probably limited to other J-series engines. I know that people have done the J32 from the Acura CL. I'm not aware of any 3.5 swaps, but I'm sure somebody's done it.
I know that Comptech used to make a supercharger kit for the J-series but that was almost 20 years ago at this point. You can fab up a turbo setup for pretty much any application, but I'd be worried about the transmission. I don't know if you're aware, but Honda fucked up on those early V6 auto transmissions. They're prone to breaking just from normal use, so I can't imagine adding a significant amount of power would help.
Have you looked in to bolt-ons? The factory exhaust manifolds on these cars are pretty restrictive. You could find some power with headers and a catback, especially if you do some tuning.
