Larger wastegate for small turbo!?

Recommended Posts

I'm in need of a wastegate. I'm going to use a 14b (TD05H) on a D16z6 and shoot for 200whp. Maybe 8 psi or so? I need an external wastegate. I read this:


Wastegate sizing

One of the more popular misconceptions about wastegate sizing is; the more powerful the engine, the bigger the wastegate is needed. This guide indicates the right size of wastegate:


big turbo/low boost = bigger wastegate

big turbo/high boost = smaller wastegate

small turbo/high boost = smaller wastegate

small turbo/low boost = bigger wastegate


How much of this is true? My friend said a small WG would be ideal for me. He said a 38mm should be good. What do you guys say?
