you dont need a big one thats for sure.. a 38mm is standard size and will work fine. When you have more exhaust gas going past the turbo you will have less going out the gate so a larger gate is not necessary. A car boosting low psi has more desire for larger gate because alot more of its exhaust will want to be dumped out of the gate. http://www.tialsport.com/technical.htm for additional info.
