if i am not wrong the bigger the diameter, the higher you can boost.

is installing a wastegate neccesary ??

 

[dolly]

ur stock turbo edi got an internal wastegate, unless you changed turbo edi lar

 

[jinkl]

erm depends of ur usage
like for me the internal wastegate rosak and caused overboosting
so i changed to external 38mm me 63t evo also

all turbos got internal wastegate ah ??
wat if i just make a wastepipe ???

the wastepipe will help the exhaust breath better by separating the internal wastegate air from the exhaust air... thus making it better flow...

Doesn't mean bigger will get higher boost. When bigger, more exhaust air will be letting off so the boost will be low, unless your mech screw the wastegate very tight. My Thai 38mm Trust last time allow me to boost up to 1.8bar. :)
