GTM makes a 4.1L stroker kit for the HR. That would get you closer to 340rwhp.

what would be the benefits of a stroker and the sizes 3.8, 4.1,4.2 and the 4.5?? more torque yes, but would it limit the rev's? Basically could some one justify why to spend more money on a stroker please? thank you

You should really pick up a basic engine building book, it will answer alot of these basic questions

No one here can justify any of this to you - it's up to you to justify it to yourself. It's a toy, a hobby, and ultimately, it's just a car. The only one who really is going to care about it is you.

really if you don't know what to do about HR to DE headers, you have some research to be doing.
