no - he bought a Silverado

It was done in Brisbane

I am thinking of buying a Landcruiser 105 with a 6.5 Turbo Chev diesel and LPG injection. Its done 285,000km. 105,000 on the diesel engine. What are these conversions like? How many more km's will I get out of the engine and vehicle? Whats the economy like? Any thoughts welcome.

Got twin tanks on mine. I have 95l usable in the rear and 50l usable drivers side belly. I think the tank is an APA ?B80? I have twin fillers and a switch on the dash to choose which tank. I have a 2 inch body lift to fit the tank in.

I changed the reflectors on mine and that alone was the biggest upgrade. I then made a custom loom with 4 relays. This has helped a bit too. I am still running 55/60w globes and it does a good job. I may change to 90/130w soon.

Horse - I got mine going by using a TB42 distributor and straight gas. Really happy with it.

I dont think you will find any "grenade" utes. Nissan only had 4.2 TD as an engine option up until then end of the GU5's. When the released the GU6 they dropped the 4.2 TD and brought it out with the ZD30 common rail engine. My understanding is that the ZD30 common rail does not blow up.

quite interested in this. my mate is rebuildind a tb42 for turbo atm and wants to get a cam done. create: all the tuners i've spoke to say 225 is better size than 425. people make 200kwatw with a 225. just what i've been told I'm no expert when it comes to turbo engines but from what I have seen a ...

Steve, I wouldnt say that I am an expert on this one but I will throw in my comments. I think your impco 225 is too small. I dont think it will have enough flow for a turbo engine. Are you running straight gas? Is your regraphed dizzy still running vacuum advance? I got rid of mine and ran about 20 ...

I dont think there is anyone that makes a new cam, you can only get a regrind done. I had mine done by Camshaft Services in Adelaide. I had it reground for LPG. It just has more duration and a slight change in timing. It seems to work well. I originally had the cam made for my TB42. Then when I ...

Inlet manifold has a completely different stud pattern. I think the ports are bigger too on the TB45

The TB42 engine has an extra set of oil galleries that feed the head through the front of the engine. If you put a TB45 head on, the galleries arent there and you then get oil leaking out the front of the engine between the block and head. No amount of hylomar could stop it. There is probably a way ...

I have tried a TB45 head on a TB42 block. "mungaGQ" has a TB42 head on a TB45 block.
I now have a complete TB45 engine in my GQ.

Head TB45 head on TB42 block no go. TB42 head on TB45 block is OK but not advised. Inlet Manifold No - inlet manifold unique on TB45 and TB42 Dizzy can be swapped with some modifications P/S Pump Yes direct bolt up fitment Extractors Yes direct bolt up fitment If you want more detailed info just ask.

It was well worth the conversion. I also dont have any risk of cracking a head as its rare for TB45 to do it. I have done a lot of work to the engine also to prepare it for LPG. I have a build thread on 4WD action forum, have a look there to get the info rather than me post it all here again http ...

Bad Mav - you were right on the money! I ran a coil of fencing wire inside my intake hoes and it fixed it.

Thanks heaps!

I have a GQ with a TB45 engine fitted. The engine wont rev past 3000rpm on fully throttle. When it hits 3000rpm it stops dead and misfires so it must be electrical. If I drive away slowly with half throttle it will rev to 6000rpm. I have removed the rev limitor from the rotor button and I can find ...

I am in NSW and I swapped the TB42 for a GU TB45 and it didnt need engineering. I went to a NSW AUVIS garage and he filled out a from for the engine replacement and then did a blue slip.

Use shims, I think 2 per side should do the job. Wont be much good as a shopping trolley tho - it will scrub tyres.

The mounting bracket or adjuster can bend and then the pulley doesnt run true. Check the belt tension too. Roo Dogs sells a full rebuild kit too.

I've had a V6 and I4 RAV4 as a company car. They both go really well on sand. Fuel economy can get really bad in the V6 tho. The I4 has more than enough power.
I had the V6 in some really rough terrain the down hill accent works tops!

Stick a GU TB45 in it. Well worth the effort. Doesnt need engineering. Bolts straight in.

I think the throttle body is 65mm internal. Fits directly to GQ throttle cable dont know about GU.

I have a TB45 engine in my GQ. I am using a XF throttle body. It works really well. I polished the internals and removed any casting marks also. I made up a new flange plate and had it TIG welded on. Really simple modification. http://i325.photobucket.com/albums/k371/createtech/Patrol/IMGP1073.jpg

Hone $80. Surface gring $120. Rings $160.
I had a mate do the weight balance for me.

Over the past couple of months I have had the TB45 bottom end rebuilt. I had the bores honed, new rings, decked and weight balanced. I couldnt afford to get the engine rotational balanced so just got all the components weight matched. I pulled out the old motor and stuck the complete TB45 engine in ...

No the law is for cars built after 2003 manufacture. The emission laws are much stricter. If the car is uncommon and you are pioneering the conversion then you have to get the car passed for emissions and ADR's. It can cost heaps - so getting LPG vapour done is much easier.

I noticed a small puddle appearing under the front diff pumpkin on my GQ. I cleaned up the area and left it. When I came back the next day and had a good look I found I have a hairline crack in the weld about 50mm long. Can I drain the oil, grind back and then mig weld it? http://i325.photobucket ...

Just doing the conversion now. Engine mounts are exactly the same. Gearbox exactly the same. Gearbox is the same. Really easy.

my vote goes to bighorns too. I'm really happy with them.
