You have to get the file size under 180k each before you can upload them to Rennlist. Try that and if it still doesn't work, you can e-mail them to me.


I've tried rotating the WG every which way and nothing works. As I start to get close, I always end up with either the WG hitting the torque tube or the pipes refusing to move any more.

I'm not sure what you mean here. Are you looking for a pic that shows more of the crossover pipe?

Jake,

Recheck the orientation and mounting of the plates. I can see the one that exits the WG (with the notch in it) is in the wrong position. It's been a while since I put a 38 mm one on so recheck your (attachment) plates. Pauerman, post a picture of yours mounted since you have the same set-up.

Yes, as most have mentioned here you should have another connection between the waste gate and the cross over pipe.

Jake951

OK, I'll shoot another photo tomorrow and post it here.


I believe the notched plate is correct. There are two notches, on opposite edges of the plate. The notch that you don't see in my first photo is facing the underside of the bell housing, which is where it has to be to allow the plate to clear the housing.

Thanks guys for the suggestions. I'll give it one final try tomorrow.

Jake 951. Make sure that the cross over pipe bolts(3 of them) are loose and that the dump tube to exhaust joint is also not tight. That should give you some additional play.

I finally got the WG in this afternoon! It was a VERY tight fit, but it did go in. There were two things that helped in the end and may be helpful to anyone who attempts to install a Tial in the future.

First, I finally realized that at the inlet/crossover pipe slip joint, the two pipes do not quite meet head on when the WG is in the correct alignment. You have to wiggle that joint around to get the inlet pipe into the right position.

Second, you have to install the adapter plate mounting bolts one at a time, alternating between the inlet and discharge pipe flanges but leaving the bolts quite loose initially. Once you get a couple bolts threaded into each plate, you start tightening down a bit, which starts to force the WG into alignment against the resistance of the pipes. This also lets you get the remaining bolts into each plate because the bolt holes will now line up.

Thanks to everyone for all the help. I would have given up if it hadn't been for the advice I got here. Rennlist rocks!

At last....

good work, brings back memories of the weekend me and my 4 jack stands spent together unbolting the old exhaust.

Jake951, Now that you have the WG in, how does it work,Less lag?More boost?? Thanks,FRED

Jake951

The results are a little surprising. I can't tell any difference between the Tial and my old Guru WG! Boost builds very quickly with both WG's, but also rolls off from 18 psi in the 4000-5000 rpm range to about 15 psi at redline with both WG's. The reason I went to the Tial was to fix the boost rolloff. Based on this little "experiment" I think I can now condlude that (a) an upgraded WG, even as good as a Tial (this one with a 1.1 bar spring), doesn't solve all boost problems, and (b) my turbo (the stock K26/8) must be running out of poop in the upper rpm's and is the real culprit here.

A couple other observations on the Guru vs. the Tial WG's...with both WG's out of the car, I did a test feeding pressure to the inlet ports and observing how much pressure it took to crack the WG's open. The Guru starts to open at 13 psi and the Tial at 17 psi. I believe the Guru spring is rated at .75 bar, although there is a new one now with a stiffer spring.

Also, I connected the Tial directly to the banjo bolt (no boost controller inline) and it develops 14 psi peak boost. This means there is at least 3 psi drop between the banjo bolt and the intake manifold.

If you want to sell the guru modded wg to recoup some of your cost drop me a PM as my new car will have a stock wg on it and I can buy the newer stiffer spring from guru before install.

Jake951

Thanks, but I already have a buyer for the Guru WG.

Jake, time for an EBC!

Jake951

Yeah, I've thought about EBC, but based on the evidence I've seen, I'm not sure any EBC would solve my upper rpm boost rolloff.
