    No play in turbo shaft and spins freely..
    The quality looks good for the price..
    I followed a few builds with these turbos and decided to give them a try..These will be for the track..may get another set for the street.. 20170425_143855.jpg

    Nice build.

    I've been using this technique to prime the oil pump. Easiest way ive seen.

    yes I have seen this on youtube...
    This would be ok on a running motor but on a new build you want to prime complete engine ,especially lifters , crank journals and cam bearings

    This pump runs with your drill
    Hook up hoses with one to oil
    Filter housing and the other
    Hose in oil can and prime away
    You can also hook up to oil pump
    Plug on front side of engine

    also wedged a short tie strap inside to help lock it in place..

    Where are the air cleaners going to mount/be fed from? Hi beam h/l's going away?
    From the description of the down pipe location, are the w/g's going to open air, too?

    Going to put longer 90 bend so the turbos will sit behind the head lights like the yellow banana and run the air filters the same..
    The down pipes will curve down and exit in front of front tires ..
    maybe later run dual exhaust, but for now they will dump out the front fenders
    waste gate pipes will be routed to down pipes after they are in place and
    also may move to 90 bends..my fabricator is super busy so I'm collecting
    parts until he has a spot in the shop for me..
