Been there long ago, with both my FJ-60 2F and later with my FJ-62 with 3F. This motors on a lighter FJ-70 rock but on the heavier wagons never were fast.
Even after a boost limit of 6 pounds on my turbocharged FJ-60, rings were blown after less than 10k miles. It was an animal but unfortunately didn´t last much.
Did some light mod on my 3F FJ-62 but again I was quite dissapointed.
There is nothing better than increased cubic inches and a lot of more torque available to pamper such a heavy baby as the FJ-80.
If it were mine and the 3FE have a lot of miles on it, I would replace it with a standard or stroked chevy 350 without any hesitation. ( I still remember the nice feeling of my FJ-40 chevy 350 equiped).
Or just keep it under Toyota brand and would look for a FZJ engine with low milleage.
On my younger days I had a Malibu Laguna with a maxed LT-1 with more than 400 hp and a BM modified auto transmission with a 3500 rpm stall torque converter and believe me, it was a nightmare on trafic. One day I got tired and replaced it with a stock 454 LS-5 bigblock motor and a stock turbo 400 transmission ...... and that was the first day I started to enjoy my car with humongous amount of torque, a minimum you could barely feel, a rocking start no matter how fat were the tires and zero problems like I had with the high lift camshaft etc. that the older massaged small block motor had.
In short, a stock motor will give you years of peace of mind and will have less items to break.
Just my grain of salt

she turns heads around here.slow vs fast off road.when you can crawl slow you tend to brake less s***.these old motors are designed for lasting longer add a bunch of horsepower s*** starts braking
