hi guys as my old 3.0L engine in my 91 lwb patrol is getting a little bit sad 370,000km sad to be accurate i was wondering if i could replace it with the bigger 4.2L without to much hassle would it require a engineers report (i am in victoria) and would there be any other hassles (besides removing silly grin from face because of more power)
must admit i would like the extra power up the hills whilst towing
any help appreciated
warm regards simon

I think it would be cheaper & easier to trade it in on a 4.2.

I pretty sure I read somewhere on a nissan forum that the 3.0 lt has a different drivetrain - gearbox diffs etc. Totally agree with the above

Another option is to fit a VL Commodore Turbo Engine. Unsure as to engineers report requirement in vic.

Andrew Patrol is correct.. Gearbox, wiring, etc etc the works is different. it wont be as cheap as you hoped. But you do have 4.3 diffs, the only good thing on a 3.0 :(

For the cost you are going to go through, it would be cheaper to go the VL Turbo (Same engine anyway just NA instead of turbo) motor than the TD42. Or even a 350 Chev conversion.

thanks to everyone for your help certainly not as easy as i had hoped although i do like the thought of the turbo from the commodore might look into that one

Also make sure to research the torque characteristics, a turbo motor doesn'do much down low where you need it for 4wd'ing. do yourself a favour and go the 4.2 route. that way you can spend more time using it than fixing it.
