I am looking at repowering my tb42 88 patrol. I am going a bit unconventional and chosen the holden 3.8 v6 with t700r auto box. Marks do a adaptor plate for the box to patrol transfer case. I was wondering has anybody done this before if so any hidden suprises i should know about. I have a whole car for a donor vehicle so mounts looms etc are not a problem also gear ratios are very similar to nissans auto. My reasons for converting are high fuel economy poor engine running and lack of EFI (carby probs) car has only travelled 124000 klms, any ideas on new consumption figures. All help is greatly appreciated

Save your time, spend a little money & reco the carby - also if you live where you've easy access to LPG you may like to consider installing it?..

124k's is still fresh for one of these engines?

Hope this helps..

Thanks for your reply

I have had the carby rebuilt and new ignition put in converted from points to electronic hoping to alleviate tuning probs however the car stays in tune for around 1000klms soon as you get off road the car works harder and then starts to idle poorly and develops a slight miss coupled with the apin in the but auto choke that never seems to know if its coming or going. I also have looked at gas but the car has to use a helluva lot of fuel to justify the gas setup cost for the klms we travel.

I've got a VT Commodore and it's very ecconomical but when I tow my boat I find it drinks a bit more. A patrol is faily heavy to begin with probably twice the weight of the VT so i'd be surprised if it's worth your trouble. Like the post above at 124k the engine has plenty of life. Just get ethe carby overhauled.

From memory I did a trip up the Albury and I went through about 50l for 300k and I would get less than 10l/100km normally. Car weighs about 1350kg and the boat is a large aluminium runabout with largish outboard.

Mate,
Any idea on how much that conversion is going to cost?
If it was me in your position, I'd be seriously looking at a Chev 6.2 or 6.5 V8 diesel. Excellent economy and more torque than a ladies bowls afternoon.
I think they cost around $10K but not 100% sure....fitting would be extra.

Thanks roachie for your reply

Ive actually got a whole vn donor car for 250 bucks and need new mounts and adaptor kit from marks for the transfer case so i should get away with the conversion for a couple of grand doin most of the work myself of course. The only problem with the import diesels is parts are hard to come by in the bush and high fitting/ purchase costs i would be better selling my car and buying a later model 4.2 deisel.

Another good engine to go with is the VH45 out of a Jap Import, V8 4.5ltr front cut is about $3000 with everything you need.

Sandy Bowman at Aus4wd in Bayswater Vic has done one, and knows everything you need

VH45
DOHC V8, 8 cylinder, 32 valve, EFI
278hp
out of a Infiniti Q45

bit of info from a google search

Nissan V8s
The Nissan VH45DE and VH41DE motor, as fitted to the luxury saloon Infiniti, are the sole modern Nissan V8s. The VH45 V8 has a swept volume of 4.5 litres and produces a maximum power output of an easy 201kW at 5600rpm. Credited with the same peak power, the smaller VH41 (4.1-litre) version needs to rev to 6400 to match the '45.

Designed as a rear-wheel-drive engine, it is quite similar in specification to Toyota's 4-litre 1UZ-FE Lexus V8, but the VH45 in particular has a fatter torque curve for added flexibility. They are extremely quiet and smooth power plants with the potential for monster horsepower through their multi-valve alloy heads. Unfortunately, we have never seen any of these engines in modified form, but it would be fair to assume 280kW could be reached with simply a good exhaust, up-spec cams, slightly higher compression and a well sorted programmable injection system.

Note that a highly modified version of this engine design (pictured) is currently being used in the US Indy Car series, where it pushes out over 550kW!

Thanks for the info i hadnt thought of the nissan 8 I have a quad cam 1uzfe 8 in my vk calais top motor but am worried about high fuel economy if transplanting into the patrol this reason is one of the main reasons behind the repower project. I am after a more economical engine package that is both reliable and if something does happen parts must be readily available in remote areas. I have looked at selling and purchasing a deisel patrol but with only 124000 klms on the car its too good to sell its still like new bar the paintwork you wouldnt happen to have a contact number for aus 4wd

Thanks for the great info

Have you thought of a TD42 transplant. You will get econ, and reliability matched by no other. 500,000 is common in one of these.

Im actually just talking to a mate on ICQ, he has stripped his down as it had a rattle in the top end, The motor has 550,000klms on it, it still has the cross hatching on the bores from NEW...

Nick W says:
And cros bleep ching is still clearly visible in liners even after 550,000kms!
Nick W says:
no ridge in bore either--im amazed

He uses Rimula X oil and filters every 5000klms.

Any questions on the VH45, call Sandy, he is a top bloke and really willin to help. He loves those sorta projects.

to buy a secondhand td42 is not cheap though. One at a wrecker I was at recently was a new td6 he reckoned he'd get $15k for the engine as it virtually no km's on it. Not sure what one is worth with hundreds of thousand km,s.

$15,000.. I would not bother walking into that place again, the bloke is a crack user... tell him you can get a whole car for less, take the motor, and sell him the rest of the car for about $50,000 at his prices.... LMAO!!!!!!

There was a TD42 WITH safari turbo AND intercooler about 18mths ago, for $8000. Take the $4000 of accessories off it, and its cheap.

No conversion is cheap. The VH45 conversion COMPLETE is about $13,000 Inc Engineers cert.
