@capsat thanks for tagging,
@imran.sh18 If you're in Karachi, there's an experienced machnic who've worked on Pajero Minis, his name is Ishaq on Jamshed road, the workshop name is Raja Autos in Total petrol pump street.
I'm against mods in vehicles, but max I'd recommend is converting your Pajero Mini to manual 5 speed gear, that's about it. The more you go technical on mods, more problems you'll have to deal with issues later on. Unfortunately mechanics we've are not certified or actually know how things are working, they learn by hit and trial, and always do experiments.
Wish you good luck
