You should probably get a 2g turbo exhaust manifold and just stick the 14b onto there. The injectors though, you might need something that controls fuel such as an HKS-AFC. I have read a few things about it and heard you might need a M/T ECU because the A/T doesn't know to add more fuel to the bigger turbo. Do some searching, you might find what you are looking for. Hope that helped!

You will need 450cc injectors and a manual ecu to run them right!

My friend has recently done the 14b swap. It def. gives a noticeable power increase. He got the 2g mani, 450's, and 14b. He didnt swap ECU's either. Maybe thats a contribution to his backfiring, and fuel cut. Hes only running 15psi.

Hey, I'm turbolaserAWDrs's friend. I have a 91 Talon TSi automatic with a 14B, 450cc injectors and a 2G manifold. My car ran much better with these upgrades but if you are going to do this...get the 2G o2 housing and 1G manual ecu. I am in the process of getting these parts to complete the swap. The parts aren't needed but they are gonna make a difference in the long-run.
