pretty sure it can be done. check with some suppliers of the engine as they usually also do fittings. it would be an awesome machine but would the cost of it all be sensible compared to rebuilding your motor and fitting a turbo or replacing with an low milage turbo from the wreckers. i have a 1hz 80 series towing a 19ft full size van and it does it allright except on hills of course but then who really cares about going fast. your decision really and if you go ahead with the chev conversion i think many would be interested to know the results of before and after etc.

All depends on your budget.
Conversion will cost you about $13,000 where a turbo will cost you $4000...

I was over at Piranha (Melb) approx 2 yrs ago and a dude pulled in with a 75 series flat top that he had just put what he called a 'small hummer diesel' into.

From memory he said it was a 6.4 diesel Chev motor, no doubt the same thing you are talking about.

It fitted OK (just) and he used a MARKS adaptor kit to mate it to the transmission. He also muttered something about it allegedly being able to do 200kph plus.

I am guessing, but I reckon you would need extra fuel tanks as it looked a 'thirsty' mother.

Troopie1,

Got a 6.2 in a 60 series wagon...4 yrs now
Lots of torque in low end; 8-8.5km/l half ton load East coast [high density diesel] worst was 6.5km/l in Darwin [crap Asian fuel]
I have heard reports about conversions going through clutches [1st gear is now VERY torquey]...couldn't justify the $ for a longer tooth.. really needs a longer 5th/overdrive as 100km/hr is just past the 'optimum' economy range....can't see 200km/h unless it had a custom box [ I think mine redlines @ 3500rpm]
Problems:1. I think I am up for injector/pump work [staggers & hunts around 1200rpm]
2. Belt fitting is a pain
3. Fitted 2 fuel pumps
I think if you intend to fit the unit yourself you could get it 'just right' [ in particular the alternator] Chev recommends 2 starting batts...found 720cca just short. You will need a good radiator or it will overheat on hill-climbs [the Melanie & Toowoomba ranges catches mine out.

Hope this helps

Guys in our club tow 2 tonne offroad vans with 1HZ 80 Series Cruisers. Slow on hills but fine everywhere else.

Check out Brunswick Diesels in Brunswick Junction - they supply and fit the 6.2 and 6.5l Chevy v8's. They have a great reputation and I havent heard anything but positive comments about them. (I think they also fit turbos to them - imagine what a beast the troopy would be then!!!)

A Friend had his 4.2 deisel GQ patrol converted to the chevy 6.5 at Brunswick Deisel. They do a very professional job, very impressive power and torque outputs.
it certainly makes me want to convert my GQ over to one also!!
He also have the diff ratios changed over to the patrol 4.8 ratios - Brunswick do this converstion, and that made a huge difference in driveabiity when touring, as it now revs at 2200 doing 110kph as opposed to approx 2600 at 110kph..

Coops (Pilbara) replied:

I believe the 6.5 is a better option as 6.2 has overheating issues.
Know of a guy in Pilbara who did this conversion (started with 6.2 and then went to 6.5) in a 75 series troopy. Awesome machine. My brother has 6.2 in his 60 series - again an awesome machine but fuel pump issues.
Nothing too serious but issues all the same.
Looking at the same conversion into my 80 series (6.5 that is)
Hope this helps

you also have to consider your insurance as a lot of companys wont insure these changes, also they are very noisey motors inside the cab. Col

Got a Brunswick 6.5V8 in my HJ75 and a Detroit Locker diff. It goes pretty well. Could do with a slighly taller 5th though. Just had to replace the clutch with a HD item.

Not as sophisticated as a Jap turbo, but HEAPS more fun. Just wish I could get a Detroit 8V71 and an Alison under the bonnet - now that'd be a combo.
