Just got my 60mm wastegate in the mail today. This thing is huge. I am hoping that the boost creep is eliminated with this huge wastegate. If it doesn't eliminate it then I would be surprised. Fitment looks like it is going to close to hitting the hotside of the turbo. But I think it will fit.

Does anyone know if the fitment with the 60mm wastegate on the full-race manifold is hindered.

Yeah, I got the 44 manifold and I bought the 60mm. The wastegate somes with a flange that works with the 44mm flange. I was just wondering if I weld this flange on the manifold and use the 60mm. Will it come in contact with the turbo on the full-race manifold.

The 60mm wastegate still creeps, but not nearly as bad as the 44mm setup (1-2psi compared to 6-8psi of creep)

I'll actually be tuning a 60mm WG setup on a built, GT35R-powered A2 tomorrow.

I can post the boost plots, if you'd like.

And it all just BARELY fits.

depending on the car ur using. if eg the single 44 should point back toward the firewall. I dont see the 60 gate fitting there exp with a adpapter flange. When i had that manifold the 44 was 1/2 or so off the firewall. You might need to angle it.

D-Rob. That would be good if you could post that up for me. i am hoping that it will eliminate it completely, but if it only creeps 1 or 2 psi, I can deal with that. I am working on a new top feed pipe right now. It is huge. I will post pictures up as soon as I get it welded tomarrow. My setup is on an EP. Real tight clearances.

Here's the pressure graph with the Full-Race manifold with 60mm wastegate pointing down towards the transmission in an EG.



Holds it very nicely.

Thanks Rob. That is exactly what I am looking for. I will be running an 8.6 spring so this should put me right around 9. Awesome. Thanks for the graph.
