I would think running it to the mani would be a bad idea considering how much vacuum you'd have sucking on the can.

I emailed FM to see if their can would work, they said the only thing is the pin diameter. How big is the pin on the Greddy WG?

I've been running off the manifold for over 10K miles with no problems.

It may depend on the quality of the actuator. The diaphragm is cupped like the surround on a subwoofer. Running off the mani causes the cup to invert when under vacuum then pop back under pressure. It cause stress and premature failure of the diaphragm. But to each there own.

If you guys need a wastegate can that can hold high boost,I suggest going to a auto wreckers and find a 1st gen mitsubishi eclipse and use the can off the stock turbo.I'm pretty sure the stock wastegate is set to a 10 or 12 psi minimum.

Well, I saw on the FM deal of the day that they are selling a T25/T28 actuator for $30. I called and asked if it would fit the Greddy and they said, "probably not without welding it." So if you can make it work, it looks like a pretty good deal. Today only.

I don't think so. Mine is about 8psi. Didn't they use some electronic boost modulation to get to 10/12 psi?

That's the FM2 type with the integral bracket. The one I'm trying to figure out is the FM1 style with the straight arm and no bracket.

I suppose I could fab an end for the FM1 style can pretty easily.

I'm not giving FM any money
I do have easy access to a torch and a welder, so persuading something to fit is just half the fun.

Even though the boost is regulated by a electronic boost controller,it's still alot better than the stock greddy one.If you compare the physical size of both wastegates,the one from the DSM is alot bigger.

It's worth a try,you can't loose for the price it can be picked up for.

If a 14b actuator will work, then the ones I have, see pics posted on page 1 should work too.. a 14b and a 16g are externally almost identical.

I have 4 of these units that I will let got for like $10 a piece or whatever...

ben are you still looking for one?

a local guy here (rappadan), got a hold of two old 300zx turbos. it bolted right into postion like the stock wastegate, but the rod needs to be lengthed about 1".

ill let you know how the results are. but i believe he might have a spare.

If it is just a matter of extending the actuator arm, could you use something like this (if you wanted to avoid welding):

They don't specify the threads, but it may be standardized.
