depends on the turbo and the power level you are looking to attain. essentially, a bigger wastegate allows more air to bypass the exducer and is a bit better at controlling boost. However, bigger isn't ALWAYS better; it needs to be matched to the turbo and the boost level you are wanting to run. Generally, a 38mm with either a 5lb or a 10 lb spring is great intermediate size.

The stock auto should be ok on 350whp, but I would definitely upgrade your stall and maybe stick in a tranny cooler. Don't expect it to last forever.
38mm wastegate should be just fine for that power range. 10 psi spring.

the oil cooler would be a good idea

But isn't that the point of going turbo? To drive faster and crazier than you could ever could in the SC?

38mm will be more than enough but a 10 psi spring??? no sir not unless you want to blow your engine or your planing on gettting a head gasket 10 psi is too much for stock compression unless your running 100 octane . im running a .3 bar spring and just using my boost controller to hit about .6 bar but my head gasket and arp head studs are on their way

My mistake; I always assume people are going to fix that compression ' problem ' when going turbo 
I wouldn't run more than 7 or 8 psi on stock compression, and no bigger than a 61mm compressor wheel (SP61 or similar).
