Nissan Patrol 4.8L Manual Transmission

Thanks dear.....
The Torque of 4.8L engine is 420 Nm,
while the torue of 4.5L engine is 350 Nm,
Justed want to ensure if i can use 4.5L gears on 4.8L
physically it can be fitted, but will any be any problem practically to do so ?

Best thing to do is check the part numbers of the complete gear box, if the last digit is out chances are it will be something minor like a electrical plug..... the further the part number has changed the more major it becomes.

Can't see Nissan like other manufactures doing major changes with the box from a 4.5 - 4.8.

Or the other thing is find a place who sells gear sets, if there part numbers are the same between to tow boxes chances are they are the same.

Its the input shaft....breaks just at the splines near the clutch plate...especially if its had a hard time apparently.
There is a thread on it in the Patrol forum...but I.m stuffed if I can find it atm.
Also from reports there...the gearbox out of a late ZD30 will fit ....just needs something removedaround near starter area of bell housing.

HTH

Hi fellow 4.800 owners, you have got me worried! about the gear box on the 4.8 ,my is a 2005 model and is running fine .What are the tell tale sign that I should look for .Cheers Uppy

Nothing to worry about from 2002 on uppy , they are seriously strong , thats why we use them.

Just 2 tips
1/ its was designed for 185kw , so don't put 400+ kw through them , thats why ours suffer.

2 , there are 2 rubber breather hoses that run under exhaust , they are easily torn off when having fun.

A/ Check regularly , as sucking water into the box isn't good.

B/ The metal pipes they connect to can be twisted and hoses shortend a little to put them more out of harms way.

C/ They like synthetic oil as well.

I knew you would have this post under control Robin, well done.

thanks makes me feel better .love the 4.8
cheers uppy

Thanks Robin.

The torque of our 4.8 is well over 900nm and the gears are fine, but we have twisted an input shaft and snapped an output shaft when driving 37" tyres so you will have no issue guys.

Hi Robin,what tricks have you done to the 4.8 to get those nm figures and what power output are you getting,regards,Mike

Basically Mike its just a great big turbo running high Boost and 4" inlet / outlet system.

Uses a Haltech ECU which can have multiple maps , 1 of which effectivily disconnects the turbo and can run LPG also (keeps it legal in that mode).

Flywheel kw are 400 now (300 rw) which is down from what is was (450kw) as we couldn't afford the parts to keep the valves under control at over the limit revs.

I don't reccomend this to anyone as Nissan may be strong but its to easy to snap something somewhere in the drivetrain.

Its been interesting though , while this car is rough as guts and has a snappy 3 plate clutch we have compared it (getting up difficult places) to my daily driver 2010 auto 4800 and I have to say that brute force does take you further.
