Full-race 4-bolt downpipe tricks (or V-band?)
Welcoming ideas on how those of us with a Full-race tubular manifold have attached the downpipe to your turbine housing.
I have a 4-bolt turbine, so I used allen bolts and lock washers. Very hard to access the top bolt though, and the far right one's no picnic. Considering getting a bolt that's too long and welding a nut to it for the right depth -- this would space the bolt head back far enough to get some kind of wrench on it.
Also considering pulling the turbo/mani out and replacing the turbine (and downpipe flange) with a V-band. Maybe mhave the turbine housing machined for the band, or maybe get a new one (ideas on where to get one? Have looked at ATP turbo but open to other ideas).
Other approaches? Please share -- I could use some good ideas. Goal is to have this car be reliable enough to put the GF in across country with no hiccups.
Thanks,
Stanford

For the Full-race manifold, I think the V-band would have one instead of 4 bolts to tighten, and that bolt should be less prone to loosening.
Top bolt on the FR manifold makes me think V-band would be my inexpensive option to retaining my sanity -- expensive option would be to go top-mount path and sell the FR manifold / downpipe.

any advantage with a V-band? Is it worth all the hassle?
I wanted to upgrade but i dont think Fullrace offered it i forget why.
Although i really havent had any problems with my setup i must say.

If you dont want to deal with the headaches , then go vband. Tial makes a nice s/s turbine vband housing.
I want to switch wastegates but the 4 bolt setup (plus my custom dumptube) is pretty much a whole day affair. My 4bolt setup has not backed out or leaked yet. Im using the 4 studs and nut/lock washer setup. To get to the other bolts, we remove the nuts holding the right motor mount and jack the motor up.
I still love the kit, but next time, its vband all the way

OK, that's a rather excellent idea on dropping the two motor mount nuts and raising the engine. Way to go. Looks like I'll have something to "look forward to" (dread a little less, to be more precise) when I get back from Christmas. Thanks again to you guys -- really appreciate the help keeping us turbos on the road.
Whoosh,

Thanks. I just picked up a "Sidewinder" ratchet and some allen sockets that I'm going to give a shot. Also picked up a couple of longer Allen bolts that I'll put a nut or two on -- idea is to screw the long allen all the way in, and then use one (or two if I double-nut) to provide the clamping -- a pseudo stud clamping setup with the convenience of an allen head to pull the stud out if needed.
FWIW, the 3" V-band housing from ATP Turbo is $390 plus ceramic coating. Based on that, I'm willing to give a few allen heads, studs, motor jacking and/or specialized tools before giving up on the 4-bolt.
