Waste Gate Size

[A34D4ME]

So I guess Tiel is the brand but what about the size? I see the 38mm is around $200 with the 40mm being as high as $350.

If I use my T3/T4 at around 7lbs, can I use the smaller one? I'll even go 35mm if I can.

Also, where is the best place to run the hose from?

I run a 35mm on my setup. Holds boost just fine.

Either compressor tap, hotpipe, or FPR line works just fine. Intake manifold will cause slightly higher boost(1-2psi) over hotpipe or comressor tap.

Intake manifold and FPR will increase the boost (2-3 PSI from stock spring )
