Wastegate Question

[pdot]

Hi Guys,

Just got a quick question here about wastegate sizing and options.

To give you a bit of context:

• Engine: RB20DET
• Turbo: TD06-20G

We had been recommended a 50mm wastegate and opted for a Turbosmart 50mm and after a few delays we finally got the wastegate but they had sent us the 60mm. I'm getting a little bit impatient to get everything into the car to start driving again so was wondering if the 60mm would be fine or if it would be best to sort it out properly and switch it over for the 50mm.

Does anyone have any input onto the best choice for wastegate size? Turbosmart on their website states:

Big Turbo/Low Boost = Bigger Wastegate
Big Turbo/High Boost = Smaller Wastegate
Small Turbo/High Boost = Smaller Wastegate
Small Turbo/Low Boost = Bigger Wastegate

But doesn't neccesarily translate over to precise measurements.

Cheers!

Big wastegates take up more space. Other than that, it should work.
