    thats a good point! Ill change that!

    Ill post more pics as it continues, I have a TH400 apart waiting for a rebuild and a transbrake/reverse manual valve body. I also have to wire up and tune the Megasquirt and the MSD 6LS controller.

    Thumbs up

    Is this your first time at this turbo thing? Looks like you really know what your doing. The quality of each step by step photo is really nice too. No gaps or guessing how it looks or how you made each piece. Really well done. Thanks for taking the time to share everything.

    Nice job of fabrication and documenting your progress. What vehicle did the upper radiator hose come from?
