hey i'm gonna build a d16a6 with a 14b sometime in the near future and i was wondering if i stayed with the internal wastegate would boost creep be present I'll be running a 2.5" exhaust. what are the chances of me doing like a 3rd gear pull and boost spiking up to like 15 psi at 5000 rpm i only wanna run about 7-8 on street and 10 on track.

just keep a close eye on the boost gauge

so i'm guessing at that low of a boost setting that it's not likely to happen but could?

i dont think you have anything to worry about, try it, if it creeps, port the wastegate

what exactly is it that causes boost creep??

Not that common. And if it does happen, in most instances it's 2-3psi increase. sometimes it can get pretty dramatic.

I dont see any boost creep in the upper RPM on my turbo D16z6 at all.

45psi

say i didnt want to use my internal wastegate, can i just weld if shut and use an external??

Your more likely to boost creep if you try to boost too low. Creep = too small of a wastegate. I've never had a problem with it.
