tial wastegates

[s5uewf]

Are the tial 46mm wastegates a bolt on item or is fab work required?
Sorry for the questions, but I have not found the local Maryland area 930 owners to learn from yet. I appreciate all the tips this forum provides.

If using stock headers, you will need to buy the 46mm Tial that is specifically designed for 930's The difference is the cooling vanes are shaved giving them more of a boxed shape to clear the stock headers (the others are more round). Other than that it is bolt on. Just don't get to crazy with the boost springs till you take care of some other stuff (fuel tuning, bigger intercooler etc)

I don't believe thats true. I sell a good amount of the WG's and I rarly sell the 930 version but as cheap insurance for $40 more ($490total) you know it is bolt on

+1 This is my understanding as well. My Tial is has the cooling fins shaved on the one side to clear the valve cover. If you have aftermarket exhaust, then it's not a problem.

Right....kuz on the other hand, I'm using the SSI headers and the Tial has the rounded fins which clear the headers just fine.....of course I also have RarlyL8's custom Y pipe too. But when using the stock equipment, the shaved fins are definitely something to consider before buying one.

MB11 should know....he builds exhaust systems along with RarlyL8.

Seek and ye shall find!

There are a number of us around.. spread out around the beltway on the MD, DC, & VA sides. Number of very competent shops around as well.

Ben, I bought a Tial WG from you for my '87 930 (OEM heat exchangers) and had to grind off quite a bit of fin for it to clear an ajoining pipe. It must've been the "generic" Tial WG. For 930 guys, I think it's better to sell them the 930-specific unit (they've got lottsa money anyway).

[AngM018]

I run the regular round Tial, but do have custom SSI headers that give me more than enough room at the WG location.

I also recently fitted standard tial style wastegate to friends car and had to cut away some material on the fins so wastegate would fit to standard exhaust system,b&b style headers etc standard tial wastegate should be fine i believe.

I run the "standard" 46mm Tial on mine and it fit perfectly for my B&B headers and my OBX headers. However, I have to remove it to get my lower valve cover off. It's not resting against the cover or anything, there just isn't enough clearence to slip the cover out once it's loose. One of these days, I'll take the grinder to a couple of the upper fins...

Yeah, once you swap to a aftermarket exhaust with the flat side Tial, you can remove the valve cover with out removing the WG.

But then, I only take the covers off once a year in the Winter to inspect the valve train and adjust the valve clearance. No biggie.

Yeah, same here.

Ditto my experience. Just a few minutes on the grinder and she fits fine.

I was going to suggest you Paul! Also there's some cool 930 owners on the dorkus site I've spoken to.

[mb911]

To answer the question if you buy the 930 specific Wg then it is a bolt on regardless.

[Chuck Jones]

I had a set of SSI headers with heat that I had RarlyL8 design a Y pipe for....and the 46mm Tial fit on there with plenty of room as you can see in the picture. This setup has been great, but it doesn't solve the issue for your stock system.
