You must have seen "Injun" or atleast its pictures, the grey FJ-40 with 1UZ that a fellow pakwheeler Nauman Shafique (Noms) had, it was sold for 1.2M the other day. He bought a 1995 model 2.7 liter petrol Surf, which takes him to office every day, serves as his vacation 4x4 as well as his future rally or service vehicle. Hope you understand what I am suggesting.
I know that you love your 40, but it has its limitations, you can overcome some but you cannot redesign it completely. You are brave, courageous and now a decently skilled rally driver. You are technically sound and have a team of exceptional people that support you both on and off the track. Youth and resources will not always be on your side.
Purely my personal opinion and certainly not to offend in any way, you need a better horse for rallies that can do justice with your enormous efforts and skills.
