Anyone have a spare set of wastegate actuators?
I am in need of a pair of actuators, complete with rods and brackets.
Need to be the "push to open" type, and around 5-7 psi boost range. I think the ones on the T3 series will work..
Anyone have a pair they need to get rid of?
thanks!

uhh,,, twin Borg Warner turbos on a LT1 motor.. in a 68 camaro.. the turbos came off a diesel, and the stock actuators are controlled by a computer/vacuum relay setup..
I either have to replace them, or weld the gate shut and add a pair of stand alone wastegates. Figured it would be easier to replace the actuators..
I found a site that sells new ones for the T3's, so I'll probably go that route

Wow, you should probably have 2 boost gauges, one for each turbo, to make sure that the load on the 2 banks of cylinders is the same! If one is a little off, it might make your engine run off-balance sorta....

With those turbos coming off a diesel, what is the turbo exhaust side a/r? I wouldn't think that would work well for a gas motor that redlines at or around 5500. Anyways, nice setup. That thing is going to be scary fast.

Re:Anyone have a spare set of wastegate actuators?
Actually, with the gates wired shut, and one of the turbos not spooling up correctly (stiff bearings, doesn't spin as well as it should) I am seeing right at 11 psi, which is too much for the combo right now. That's why I need to get the right actuators, and rebuild the one turbo. I start seeing boost around 3500 - 4000 rpm, which is where the stall comes in right now.
And I have the rev limiter set at 6500 on this motor.. the solid roller 383 coming later will be set at 7500.. :P

I haven't gotten it to the point where I can take it to the track yet.. playing on the street, I can spin the 31 x 16.5 Hoosier tires thru 1st and second..
It's a basically stock LT1 motor with a mild cam that went low 11's with a 100 shot before the twins, so I figure it should go at least that now...
