T3 w/ internal wastegate actuator + HF Manifold = :(

By teal_dx
- Tue Feb 10, 2009 4:29 am #95405 I bought a turbo off a guy with an HX in early 2006 and pieced together the rest of the kit over time.

This is how I bought the kit, and how I assumed he had it on his car.

Finally getting around to installing (I'm busy) it and was test fitting everything yesterday.

I have a HF manifold, adaptor plate, T3 turbo (internal WG) and Spoolin Performance 2.5" DP

I tried to put the turbo on and the actuator on the back of the turbo hits the block - not even close to being able to fit.

arrows point to the contact areas

Clocking the turbo does me no good. Even if I install the adaptor plate around the other way, I can't flip the turbo around and have the hot side on the driver side because then the 2.5" DP won't work (I love the DP, will do whatever it takes to use it)
Plus the turbo will be hitting the block then.

So it looks like my option is to find another manifold that pushes the turbo farther away from the block. Or convert to external wastegate which means buying a different manifold + wastegate + making a dump tube.

:x GD Money pit!

Seriously though, I hear of people running T3's and HF manifolds all the time on D series and never heard about this problem happening. Am I missing something?

I know its possible on the t25 not completely sure on the t3

- Tue Feb 10, 2009 5:21 am #95430 oh like disassemble the exhaust side and put it back together so that the actuator is on the bottom or front?
That sounds like it could work, if I can rotate it the right amount to keep the 3 bolt exhaust flange in a position to mount the DP correctly.


edit: nevermind that won't work. The manifold flange has to point straight up to the HF adaptor and the 5 bolt swingvalve/cover is always going to be pointing the same way putting the rod & actuator on the side of the block.
The exhaust side is all 1 piece.

- Tue Feb 10, 2009 3:07 pm #95486 ok heres another idea what if you took some sheet metal made a bracket to use one of the whole that are threaded on the block lets say where the p/s might of went....get something to extend the actuator out of the way and everything like that. that might possibly work just gotta work out the whole customizing bit

- Tue Feb 10, 2009 8:59 pm #95541 you're on the right path....
someone suggested I make a bracket to move the actuator closer to the hot side and shorten the rod by a couple inches. There's not that bulge in the block a couple inches to the left.

I still have not ruled out buying a non-AC friendly cast manifold that will push things out a bit, if I can find one for cheap.

- Tue Feb 10, 2009 10:50 pm #95574 tried that, 2 problems.
The whole turbo is closer to the block since the flange is more offset to one side. the back of the exhaust housing hits the block.
And I'd have to ditch my Spoolin DP which I love :(

Ran in to this when I ran a TD05H on my HF mani. Ended up buying a smaller internal gate off a 86-93 Supra Turbo (7MGTE with the CT-26 turbo). It has a double bend in the acutator arm that allowed me to move to a diff mounting hole.

I've also seen the o2 bung on the manifold used as a external gate port if you don't mind going that route

- Mon Feb 23, 2009 12:03 am #98281 yeah but I thought that could put a strain on the studs. I'm going to shorten or extend the actuator arm to make it fit :thumb:
Also got a deal on a cast rev hard manifold so I'm going to make a WG block off plate and see how everything fits with that :thumb:

- Mon Feb 23, 2009 1:23 am #98295 Can you come up on 2 thick exhaust mani gaskets or one thick and one regular which ever works and slap them on?

That should push the hx mani out some.
Like that you don't have to worry bout customizing the wastegate actuator.
