    How Much It Cost You To Do Your Swap?

    Everything I used on my 1j could have been used on a 2j. All rand new parts. My car runs flawlessly. And doesn't leak. Just need to look in the right places. And do ALL the work yourself.

    What does it take to go E85? Advantages/Disadvantages?

    When i went to uti they had a gto 6.0 with a rear mount turbo. Only made mid 400's. With a cam intake and exhaust and tune you could make more than that with a ls engine.
