Rn85r hilux putting a 4y in place of the 2y


Recommended Posts

Hi all im just after some info on the 2y vs the 4y motors are they compatable for a bolt in swap. Are the bellhousing bolt patterns the same? Are the engine mounts the same aswell as the whole clutch setup. I ask because im looking to upgrade the standard 2y for a 4y that is in my rn85r. I have looked into all the other conversions around and im just not intrested in spending that much extra effort. Even if i had to get a sutible 5 speed gearbox to upgrade the 4 speed in the old girl. And yes i have tried using the search function but thats not much help. Cheers fellas.

Hi looking at other forums there’s someone who wants to change their 4Y engine with G52 gearbox (G54 - upgraded version) from a Toyota 4Runner to a W56 gearbox. If he has the 4Y with the same G52/54 gearbox as the 2Y then surely the engines are interchangeable.

Yeah my cousin is running a 4y / 5 speed in his Ol Stout tray back, on gas, tows a small van all up and down the east coast, dropped straight in, BUT my Little workmate with its injected 2 Litre-1RZe, still has more KW and Torque, actually between the 3y and 4y theres only a bee,s d*ck in power gain, put up a link for you to browse, Cheers Conrod
