Keep us posted with this one! Why did you changed from STP to Wagner (i know the pros and cons)?

I will change, since I very much doubt the lifetime of the STR for that 250 USD I payed for it. And since I will change turbo anyway I find it a better choice to avoid a disapointed GT3071R setup because of the STR might not be the best choice. I mean, the STR has not disapointed me until now and might be perfect for a RS2 setup or even a S2 backup solution.

I have thought about it for a long time and said to myself, why not keep the STR and see how it flows with the new turbo, but I simply don't want to do a EM change once my new turbo setup is not running ok.

I think with the Wagner EM I just play safe with EGT and get the most out of the turbo and my engine. But maybe it is just a thing between the ears..... I just know the Wagner is suited for the job for sure

It's on my car now! I have no pictures yet of the final install, but all I can say is that it fits nicely and looks great. I had to shorten 3 manifold-head studs to get the EX manifold be fitted nicely. However it was a pain in the *** to bolt on the middle lower bolts, since the space is so limited and very tight between the cylinder head and manifold.

We took some pics of comparing the RS2, STR and Wagner manifolds next to each other as well as comparing the RS2, a K27/26#8 and my new GT3071R turbo. After this shoot the battery got no juice anymore to take more pics of the rest of the install, so I will post these another time
