    well after a few hours of searching around ive come across two different setups..

    http://cgi.ebay.com/ebaymotors/ws/eB...#ht_500wt_1182

    http://www.blackbirdscustomtrucks.co...x7.html#1fbolt

    one has an ebrake option, the other does not. One has a 2 piston option the other does not.


    Now just lies on the master cylinder and booster. Im wondering if there are any larger units i could use to really make the brakes on this way better and less squishy.

    Awesome build, I would throw a transgo hd2 kit and a sonnax pressure regulating boost valve in the 80e for a little added insurance. Boost and weight might be pushing the limit stock.
    I'm not familiar with the 06 gto cam, but if its similiar to the ls6 cam, thats a favorite budget boost cam around most of the forums.

    well the brakes are a must now. I was driving around last night and managed to notice the master cylinder is leaking now and i was low on the rear brake fluid. I popped the cover off and the was smoking something fierce.

    Im just wondering now if there is some sort of upgraded master cylinder/booster i could use since i will be swapping to rear disc brakes from these large rear drums on my 14 bolt.

    Ive searched and searched and am just not finding anything aside from a chrome plated deal. Im wondering if there is a larger unit or a way i could like run a corvette unit or something to that degree if i wanted to without much fabricating and so forth.. The hoses are so old i am just going to get my friend who builds braided hoses to set me up with some nice hoses while im at it..

    At this rate this son of a is going to be a full restoration!

    So i think i have concluded on the manifolds i want to use, just may end up using a gto alternator bracket if i can fit it, and use the ls4 front manifold on the passenger side, and maybe a modified 6.0 truck manifold on the other, either way both sides id weld a v band fitting on so i could clock things at better angles.. This way the hot side piping can run directly out forward with a shorter charge path IMO and i can just jig up the union in front of either the water pump (if there is room between my radiator), or off to the drivers side more and just end up doing a back door setup from the turbo clocked directly into the end tank of the intercooler on the passengers side..
    Like i have it setting here just into the opposite side so the downpipe wouldnt have to clear the column and so forth.. Probably just do the bov on the other end tank, and have a clean pipe coming out of the radiator support directly beside the radiator up and into the tb.
    With the particular radiator i am going to use(copped it out of my rx7 im parting with), i have a 25"x21" radiator as opposed to the nearly 35"x21" stock truck radiator.
    Now i dont know if this is enough radiator? But it NEVER gave me problems in other setups with these motors? Perhaps with the added weight and towing with the truck this entire concept is a dumbass idea, lol..
    heres some different setups..
    The ls4 front manifold on the drivers side...
    The ls4 front manifold on the passenger side

    either way like a nut job im hard at work in my lab at 343 am, so i better get my ass back to work here.. more to come..

    Truck is at a shop somewhere in ohio... No one knows.... It's kinda a effup situation with his wife... It's hard to find good partners and when you think you have one that is there for you when that is not the case it could drive you down to your grave... Wish I could trade or give up anything valuable or body part from him to be alive...... Just always remember it could be the last time you see your close friend/family you never know whats going on the next day.
