I have a 92 toyota pickup.. and I threw a rod.. I am going to put a carb.
22r in it but I dont know what all I will have to switch or if I will have to change anything someone tell me please....

Don't know for sure, but some things to think about.
Fuel delivery (fuel pump)
wiring harness (computer for the electronic ignition)
coil
motor mounts
air intake
exhaust system
transmission (if different then a drive shaft also)?
tachometer (if so equipped)
if you have to change the transmission then the speedometer may be off
Don't know if you have any emissions testing where you live. In CA you wouldn't be able to use a carb for that year.
