    Common Engine Swaps and Related Discussions
    Hi everyone, I'm finishing up my 4th gen swap and running into a couple road blocks.

    3SGTE Turbo
    I am looking for an alternator for my gen 3 with no power steering. I was wondering if it is interchangeable with the gen 2 and if not, what alternators would work. Toyota doesn't order parts for japanese engines so I can't just go OEM gen 3. Thank you!
