20~30 minute install if your quick...

 

The actually difference in the two stock motors is programming, turbo, injectors, and a camshaft I believe. So yes with enough money you cant turn the 305 into a 325. As budget wise, its a hell of a lot cheaper just getting a smarty and turning that thing into a 405 motor

 

i have been checking them out but was wanting to know how to make the 305 into a 325 before i put the tst on it. what did they do to make it a 325? and thanks for the welcome
