Exhaust brake for 4.2
I've had a look & there are a couple of threads here with questions about fitting an exhaust brake to a 3.0 litre Patrol, but no one in those threads had actually fitted one.
Today I had some brief correspondence with a chap from another (non Patrol) forum who has a turbo'd 4.2 with an exhaust brake fitted to his Patrol which he says, (in conjunction with a 4.6:1 diff), gives greater safety descending hill when towing a caravan, as well as giving more control in low range descents when 4wd'ing.
Given the relative lack of engine braking in the turbo'd 4.2 when compared to the n/a 1hz I had in the Troopy, the idea of fitting an exhaust brake when I eventually get around to fitting a new exhaust (3") seems like an attractive idea.
The chap's exhaust brake was from SGV Exhaust Brakes in NSW & he reckoned it cost about $1300 to buy (not sure how long ago) plus fitting costs. In my book I would rather spend that sort of money to give me greater 'sure footedness' when rolling 4 tonnes down loose hills, than I would spending it on releasing more horses.
So ...... Has anyone else yet fitted an exhaust brake to a Patrol, and in particular a 4.2 (although other motors would be of interest too) & wants to share details?
I have an exhaust brake on our ED33 (3.3 litre 4cyl diesel) engined bus, & love it when in the hills.

The only good thing about an 80 series is..... the front end?? Wrong!!, the Engine?? Wrong!! the Full Time 4WD system?? Wrong!! Its the NissanPatrol.com.au stubby holder fitted over the transfer lever.

There is also a mob in Geelong who sell aftermarket exhaust brakes for Toyotas & I believe they have been used on Patrols too. These are a butterfly type, whereas the SGV are a guillotine type. (Which they claim to be be a more effective design). SGV make their own & I was told they were helpful & good folk to deal with. Not sure if the Geelong folk are just selling a product they import, or if they make their own gear.

An exhaust brake was one of my first thoughts when I knew i was getting a TD42.
In any moment of decision, the best thing you can do is the right thing, the next best thing is the wrong thing, and the worst thing you can do is nothing.

Hey Cuppa,
What about a truck wreckers, maybe you could source one from a Canter or some other small truck, It might be a heck of a lot cheaper than going brand new.

Price wise the cost is about $2500 plus forgot the mob who used to do it ,
but not worth it from all the research I did on it .plus talking to shop owner
I was only going to use it off road, get every line redone in Braid even the short ones and it will make a difference

G'day Cuppa,
had a long talk years ago with Tony who fits the SGV units in Chipping Norton in Sinney when I found how totally R/S compression braking with a turbo is.
The old standard 4.2 was excellent with the van on, the new 3.0crd with turbo is crap.
Didn't go with it but I'd suggest a talk with him. Top bloke.
Dunno the number but enter SGV exhaust brakes on the web and you're there,
regards
Col
