I have very good experience with Powermasters 170 amp units and installed several for my customers here in my country.
I am not afiliated, nor a authorized distributor or related with them just in case. I tried others and was very disappointed. You can increase the gauge of the wire used in the winding of the stator, put bigger rectifier diodes but at the end they will run very hot and sooner or later something is gona fail. Also they doesn't provide enough amps at low rpm
Powermaster use a bigger Denso case model, manufacturated by Denso USA versus the stock made in Japan. They came with a plug adapter to match their round Camry type conector to the Land Cruiser in line type.
Each alt came with a individual rating test sheet which close matched the values I measured when I checked them in my bench. Of course this values will decrease a bit when installed since they will work at the high temperatures you find in the motor and loaded with the vehicle electrical demand, and their integrated voltage regulator will limit the alternator ouput acording to this increased temperature as to protect them.
Since they came with a serpentine type pulley and it's shaft diameter is bigger, I bought a stock alternator replacement dual V pulley which will be machined to the Powermaster alternator bigger shaft.
(Take in mind that because the case is bigger, it will take a lot more of fiddling to put them in place against the stock, also the belts are harder to install since there is less tension adjustment clearance).
This is great because the customer can keep his stock alternator as a backup and ready to install in case the newer fail.
I have seen 1FZ's with dual alternator setups. They keep the stock alt but add a second one on the right side. A crankshaft pulley from a 2.6 ltr Isuzu trooper is bolted over the stock crankshaft main pulley (with longer bolts) driving the new alternator through an aditional belt. Alternator support bracket is bolted to two existing unused threads and the one exhaust manifold holding bolt.
