Modded engines

[Stephen perkins]

Not saying I'm gonna do it now but in the future because I just got this engine but where would I send my lrp .28 to get modded or does a particular person sale the modded engines?

Here are two of the more popular:

I have an RB modded STS D30M. I can say his work is top notch.
