05 GT manual and tbSTi auto questions

[MdMa]

I used to own a MY00 GC8 V6 STi, and have missed the rumble in my life.
I'm keen to get the preface lift, as I prefer the looks (specifically the headlights), and that fact it's a 2L, but of course would like to do a single scroll conversion for said rumble.

It will be my daily so I'm not chasing power, if it makes 130 awkw, that's fine.
What are the go mods/brands to do this conversion?

How well does the 5EAT cope long term; are there any common issues or should I stick with the manual?

Headers, uppipe, dump & turbo will need to be swapped out for a single scroll turbo conversion.

You’ll probably require a tune as well.

A tcu tune can help the auto shift points and line pressures.

The manual preface GT has a TY75 type 5mt gearbox, these are less durable than the postfl 6mt but can cope fine if driven considerately.
