    Ok, so the Driver side stock manifold feeds a U shaped pipe thats loops around and joins the passenger side manifold and they both feed the Turbo. Thanks for the visual aids!

    And although it may seem very restrictive this provides plenty of flow to use a 650hp buick 350. And my plan would be to just provide the custom manifold with V bands on both ends so people could just have an exhaust shop bend pipes and weld on a turbo flange. That way people can do any turbo placement they want, and it’s only a small manifold to ship. One reason to do this is that the drivers side is super tight with any turbo header or manifold as the steering shaft is there. This eliminates that issue. It also reduces the chances of broken bolts as only the one manifold is removed. And it allows people to setup any turbo etc that they want to.

    when mark sold full kits it was a hassle to make everything fit each car and peoples desires.

    It seems like it radically simplifies installation, as there is more space on the passenger side to accommodate the turbo and plumbing? Do use a larger single turbo unit (versus the twin turbo installs)?

    yes there is lots of room on the passenger side unless you have AC. And yes a GT-45 turbo or similar would work fine.

    Yes Sean is right it shouldnt be a problem at all with the "room"

    check VSracing for a t4 turbo
    Even any cheap T4 turbo will give you a lot of power that your "stock-ish" engine can handle but need to diagest :)

    I like that look! Now that I’m on E-85 I may go that route and eliminate the air to air intercooler.

    Some progress today.
    Custom driveshaft is in. As well as the 3" xpipe.

    I saw somebody was asking about 28x10.5 on 10 inch on a Stepchild.
    BS 6", longer wheel studs, 1/4 spacer makes it 5.75 BS , rear shock lower mounts relocated. Stock 8.5 rear ( posi build)
    It clears!

    Saw this Cutlass at car show today. Was his grandpa's car. He put the whole drive train from a rusted out 86 T-type for $4,5k. Said it fit perfectly. No problems, no custom stuff needed. Says It runs fantastic. Increasing boost says it will be 600hp +.
    This seems like the way to go for perfected turbo power to me, rather than 350 turbo conversion. :)

    wonder how much you can get all this for at the junkyard hmmm...
    or get you a TA aluminum block and start your own rest is easy to get this,
    would be cool in a Skylark non GS car.

    Might want to put a air bag in that right rear spring with about 15 lbs in it.

    Hey Bud' not much been working like a pig... but you are right i have to get going...the todo list is getting smaller ...
    i was trying to sort out a cheap throttle cable option but i guess i just buy a adjustable cable and a FAST mount that works with the Snipers.

    Then i should be close to starting it up... maybe this upcoming weekend

    thanks to your Ass kick i was able to finish the throttle cable. Filled up fluids, charged the battery, and updated the EFI firmware. I noticed that the starter either dont catch or doesnt engage i am off tmrw so i might have a night off beer and wrenching and MAAAAYBE i start her tonight.!
    wish me luck ahahahah
