Well Gang, my search continues. Some time back I asked some silly questions about the new Patrol and Prado options as a 4B.

I still havent made a decison though I have lately been doing some research on purchasing a high milage 80 Series cruiser, dropping it off to brunswick diesel and having them shoehorn a 6.5 litre diesel in. Isnt it sad that I even need to consider this when I would rather buy something new but as i see it there are no 4B on the road that come close to the credibility of the old 80 series. Dont bag now, just personnel preference, and remeber my last car was a 100series TD GXL.

Has anyone had any experience with this type of approach (base vehicle and drive line standing up to the new chev) and actual work quality and ball park cost form Brunswick.

Any feedback appreciated.

Cheers Pete

Just a question but have you given any thought to a new TD troopie? Might not have all the comforts but has the goods for when things get tough?? The 80 series is probably the best all-round package Toyota put together however. Cheers

I have thought of troopie but I would still like passenger car type seating and fininsh. I thought if I threw a couple of thousand at the interior as well it should come up OK. This is only a thought at the moment and prove to be cost prohibitive.

There is a gu getting around kalgoorlie with a bruswick diesal. And when I saw her in the carpark I questioned her as to why and how much. It was a 2.8 that blew up and it cost 16k with a different g/box (2.8 have lighter gerboxes) pluss a few other mods

Top rig when its done, thats what i would do in preference to new rig, have been in a 60 with 6.2 and it was awesome and cheaper to run, especially if you fit 3.7 diffs, or marks overdrive.
Should cost about $13000 ar brunswicks and they are the cheapest, best of luck im still saving lol

Wasn't there a big stink about insurance on these converted vehicles about 12 months ago. I recall it even made it into the 4x4 mag's that no insurance company would touch a Chev V8 powered 4by.

I'm with Pesty, it would be the obvious thing to do if you have the bikkies and a straight 4x4 to stick the bent 8 inside of.........just the sound of that burble would make it worthwhile.

Brunswick have been doing this for eons, i looked at it about 6 years ago but merely as self indulgence not necessity.

Can you recall the main reasons that the Insurers were steering clear?

I think the reason the ins coy's were nervous was their perception that anybody who'd do this to their 4by MUST be an absolute hoon and wanting to use their machine for racing or other dubious reasons. Never mind that there are serious off-roaders amongst us who simply wish to have a better towing capability etc.
Not sure, but I reckon that's the reason.

Wouldn't be worrying about a high mileage 80. Suggest you get the lowest click vehicle the wallet will allow. Also if the bodywork is good, go for it. Apart from the conversion, mechanical side of things would be much cheaper than body problems.

Just need twin 3" exhausts to finish it off. Enjoy...

A friend had the 6.5 put in his very clean straight, powered by 3F 80 series, it now uses less fuel, much more relaxing to drive and goes like stink. Looks like afactory setup and driveline hasn't been touched except for new clutch when motor was put in.

You know,
The more I read about the Chev V8 turbo, the more convincing it is to go that way. Long term investment i recon would be excellent. Shouldnt have sold my old GQ, damn it ! Might find out more about it actually, See who imports them, what condition they arrive in and cost to rebuild. Wonder if my account is still on file for trade prices......might check that out too.

I've got an older Brunswick converted HJ75 with a 6.5 V8 Chev diesel in it and it's fine.

Made a few changes which made significant improvements.

I have a snorkel setup with a Donaldson pre-cleaner for the serious stuff, but standard aircleaners are far too restrictive. I run a K&N rice boy filter for normal duty and it makes a big increase in power / drivaeability. A big improvement.

Also put a hot dog on it - nothing else. Made quite a difference from the standard muffler fitted. Noisy, but that's OK when it's a V8. The exhaust is a fairly cheap affair with crush bends, so the 3" pipe is really 2.5". Not good enough in my book.

Change the accelerator return spring. Brunswick put a heavy duty double spring that made it a real pain to drive which can quickly be replaced with a single lightweight one. Yeah I know it might break, but the sky might fall on me too. This has been the single biggest improvement to the 'feel' of the whole vehicle. Sounds silly I know, but trust me, it's true.

I change the oil and filter every 5,000km's with Caltex Delo Silver. This is the recommended mli spec oil for the 6.5's that all the US enthusiasts say is the go. Surprisingly difficult to get, however the Ampol servo in Spearwood sells it in 20l drums.

Get big amps through to start them. I use a two mutha extra heavy duty batteries to spin the beast over. One will do it sorta OK, but two is far better.

90km/h in the standard ratio HJ75 is a very relaxed cruising speed for this donk, so it may be worth gearing the 80 series up if required. Don't know what the standard diff ratios for that model are. Put a Detroit "No-Spin" Locker in my rear diff.

Search the internet for US information on these motors, plenty available if you look hard enough. Lots of specialist companies around.

They are not fast, but the've got a ton of grunt right from idle. If I have to take off in the early morning and don't want to wake the neighbours, I can reverse up the steep driveway of my house, and drive off without touching the throttle and go through the gears. It's a nice feeling to know you will never run out of grunt climbing a sand hill again and it'll sound like there's a 903 Cummins truck engine under the bonnet while you're at it.

Put it this way, I find my nice, modern, luxurious GU wagon sits gathering dust alot of the time as the old V8 Cruiser is so much more fun to punt around in. "Man does not live on bread alone"

Good luck Peter and let us know how you go mate.

Thanks V8

I like what I hear so far. I am looking at the beauty of the chev for power and economy not speed, i also like normally aspirated and not to high tech.

Thanks a load for the detailed repsonse. I think i will be talking to Brunswick and getting the bad news, as in cost, this week.

Thanks again, Pete

thanks for the info V8, it is of interest to me with the brunswick 6.2 chev diesel conversion in my troopie.
I always use 2nd gear to get moving, it avoids the embarrassing 'jump' in first on takeoff.
The K&N rice boy filter you mention has me curious, where did you get it from? (I'm in Perth).
There is no problem with the accelerator springs on my troopie, maybe they fit doubles only on the 6.5's.
There is a 'hesitation' when accelerating from idle (in second) after stopping at the lights, a bit like turbo lag except there is no turbo under the bonnet - does your donk do that too?

I had the V8 fitted for extra power for towing a 2.5 ton boat & trailer rig, made a big difference but the standard Toyota rear diff packed in eventually, not sure if its time was up or the extra power did it.

My donk starts easily on a single battery, btw.

Yeah 2nd is the go for takeoff most of the time. If it an uphill start or I have a load on, I get it rolling in 1st, then snap second straight away.

I got my K&N filter from a speed shop on South St, O'Connor next to Battery World but it was expensive, over $100 from memory. I have seen a similar 'looking' item from SuperCrap Auto for under $20 now. I think Repco has a sale on K&N at the moment. Just try running it without the aircleaner and see how it goes before spending any money I reckon. One thing I didn't mention is it gives a lot of induction roar that can be heard from inside the cab if that bothers you.

No lag on mine at all. Has the mechanical Stanadyne rotary injector pump on it.

I put a new starter on it a few months back which may have made a difference, but haven't tried one battery yet.

Also have an additional fuel filter with sight glass fitted and regularly use Morey's diesel additive to keep the injectors and fuel clean.

Does your Troopie feel like it needs another gear to be more relaxed when cruising at 110km/h?

V8, you're right about an extra gear, I wish there was a 6 speed gearbox. There's enough grunt to run a cruise control on the manual box but one has to be careful in hilly terrain as the fuel bill goes up then :-(
I'll check what kind of rotary injector pump is on mine, it's mechanically driven.
Battery is the standard troopie battery wit two 'z' (N?zz). The starter motor is the geared type.
Brunswick did fit a sight glass fuel filter ( Lucas I think).

I did modify the clumsy snorkel input to the standard Toyota air cleaner canister.
It came in at a right angle which meant that the filter area immediately opposite the intake hole always got clogged with dirt ( finer filter).
I modified it to a tangential intake which sets up a swirling action that uses the entire filter surface to trap the dirt (similar than the original Toyota under bonnet intake but in reverse direction).

I have no idea why the acceleration hesitation, Brunswick told me it is 'normal' for this engine. Once going though, she moves like a bat out of hell. I guess I could rev up more before releasing the clutch but that can be dangerous, especially on wet roads.
I'll have a look at super cheap for these filters, thanks for the info.

Hi Peter. A mate has one of the chev V8 turbo's in an early 80 series. It used to be the 3F motor. As far as I know, all he's done is lift it up 2" and put on a 3" exhaust. The auto box handles it fine.

He did find a silly little plate at the top af the valley with a hole in it about an inch square. This was on top of the intake manifold. He took it out, cut the hole to be as big as possible and put it back. Had improved performance straight away. I don't know what it was for, and he doesn't care, it just goes faster now !

If I had the opportunity to do this to an 80 series or GU, I wouldn't hesitate.

My Humvee has a 6.2 in it with a turbo 400 HD auto behind it.
As has been said these engines need lot's of air. The standard air intake on the Humvee came in through the snorkel hat in front of the windscreen chucked a right angle around a baffle plate and then into a huge donaldson type aircleaner, from there into the engine . All plumbing is minimum 4 1/2 inches ID.
A fellow owner fitted a deep fording kit part of which removed the first baffle (which prevented water ingress directly into the aircleaner) and replaced it with a 90 deg rubber elbow (again 4.5" ID). It felt like he'd gained an extra cylinder so we've all fitted the elbow and it made a huge difference to the performance and responsiveness of the engine. This is on a NA engine so a turbo could probably do with even more air.
On the Humvee the exhaust is 3" all the way with a straight through muffler and it normally exits in front of the LH rear wheel so is pretty free flowing. The Humvee's are also fitted with stainless steel headers which dump straight into 3" system.
All the Chev V8 diesels run a mechanical rotary Stanadyne injection pump, turbo's are electronically controlled (pretty crudely compared to modern common rail systems).
A Turbo on a Humvee 6.5 gives only a small increase in actual HP but more than doubles the torque.
I get around 16 -17 mpg out of the Humvee, not a whole lot worse than a loaded 1hz troopy. It is a brick as far as aero dynamics go though.

Hello - while not suggesting this is the best option, I think Ron Krikke Auto's in Bunbury sell "new" BD vehicles in a variety of Toyota models. I think they sometimes use old Petrol models as these are cheaper to buy and then wack the BD in. You may wish to give them a ring to get an idea of what they've got and how much.

Hi Pete,

I was steered away from them. Simply because the main reason is that Chev parts are much harder to get a hold of then genuine tojo or aftermarket parts in remote centres. I think there's a reason a dozen engineers sit around a blueprint and design the motor for the car and car for th motor.

If you are mainly doing weekend out of city runs it may be worthwile as you're not far from the parts.

For what its worth. I've yet to justify the need for one after my offroad experience. And for towing, I believe it's called a 1HZ turbo diesel - far more reliable.

The guys at Armadale 4x4 have been doing V6 and V8 coversions in hilux and cruisers for a while now. Not diesel V8's but anyway, Michael told me years ago that he recommended a six speed light truck gearbox for the V8's, but not many had the money for it. Untill they blew up the gearbox and went back and asked for the bigger one. It can be done, and I'm sure if you asked brunswicks, they'd know about this option.
