Not been on for while as car been off road in garage for 18 months or so.
Had lots to do including transfer case bearing ,head gaskets and general maintenance.
Now I got more time and money am looking to bring the old girl back out (97 Jdm Impreza).
Am bringing car back out on td04L but want something bit more.
I was running a vf22 but it died of old age and no one can or will repair it.
Just want upgrade from vf22 ,don't want to go mad so have been advised either vf34 or td05 18g. FRONT ENTRY

Engine mods are:
Decat Downpipe
Afterburner full exhaust
Silicon intake pipe
K+N induction kit

Also because it is an import which had the bigger turbo it has yellow injectors instead of Grey so am hoping these are bigger and won't need upgrading when turbo upgraded.
Thing is even though they are yellow may not be 440 and I need to know how to id them.

Would appreciate any help from you lovely Subaru nuts 😎😎😎
