How much horsepower can you add to the 6th gen accord without damaging bottom end? I am thinking nitrous or turbo and am unsure of the limits of stock bottom end. If i need to modify bottom end where can i get parts from?

 

Do a search. I can garauntee that you will find your answer.

But, I will give some insight. Don't think about turbo with a lot of P.S.I. without upgrading your internals. With nitrous you don't really have to build up anything. Really all you need is colder spark plugs and a better fule pump, and maybe some different injectors, but I have heard people working with less.

 

that question is like What is the sound of one hand clapping? unanswerable.

you could add 50 HP, detonate like nobodies business, and launch a rod through the block in 30 seconds. you could add 200 HP, have it perfectly tuned, and never have a problem.

generally speaking, the F23 bottom seems to be fairly stout. search around for dynos of other motors that are about the same as yours and see what they are putting out.
