hahahah it all done by hand and by guess work and what "looks good"

stick to factory, theve spent thousands of manhour perfecting the engine. dont let ANYONE go hacking up a perfectly fine engine

This guy has to be the most erogant person I have yet to see on this website. I say go for the mod, this guy probably dont even have a modded engine or has never seen one perform against an unmodded engine. Manufact. get it where it runs, but there is a lot of minor clean up that can be done, most have some major areas for improvement. Get a cheap engine, better, get a dead engine you dont want to sink any money in, get a dremel and some tools for it, do some research online, several sites that show good pics, and give it a whirl, compare what you have as a result to thier pics. It is not that hard, I have done 3, all of which have seen a noticeable power difference. Go for the modded, this is a hobby, it is hands on, dont let someone that dont have a clue alter your decissions. Happy Racing.
