I thought the 6HP26 was full electronic and needs its ECU to be able to talk to an engine ECU and BCU to operate.

I have asked the Volvo owner to clarify.

I personally do not know - according to the Volvo driver is not required.

Thanks for the information. I have found a power steering unit that does not change drive through 90 degrees so can be fitted in the steering column. I have seen it in a Volvo 304. The steering column is cut and about 6" taken out and the power unit is inserted - so the original manual steering box is still used - no cutting or fabrication of the chassis but cutting of the steering column. This is the unit This is the unit in the volvo with an outer cover welded in. - the pic got turned through 90 degrees - ad the forum will not let me fix it - sorry

An Aussie Army 101 doing brake tests. These have 9.00x16 tyres (a tad under 35") and the same drum brakes as a series 3 lwb. So there is maybe not a real need to go disks. Some 101s have aftermarket disk brakes - the disks do not stop better than the drums but do tend to stop straighter and require less maintenance.

For sure - but not something that a New Zulander will find in his local wrecker in New Zealand.

Sorry - what Landrover had a disk braked salsbury front end? I thought they were all rover diffs and the only salsbury were the 101 and one tonner but these were drums. Garry

More power but you will need to run higher octane fuel.

If there are side bolts on the mains then it is a 4.0 - these are visible around the bottom of the block from the outside. If the castings are there but not drilled then it is a 3.9. I was just highlighting that you can use the pistons you already have if you wanted but highlighting it would be very hi comp. You can use 4.6 Hi Comp or Low Comp pistons or 4.0 Low comp pistons as an alternative.

If you have a 4.0 rather than a 3.9 you can just put the 4.6 crank and rods into your 4.0 block - they are the same. You can use your 4.0 Hi Comp pistons but your compression ratio will be very high. Probably something like 11.3:1. The 4.0 pistons have less dish (volume) in them than the equivalent 4.6 pistons. I did the above with my 4.0 block and used the standard 4.0 lo comp pistons (rather than the 4.6 pistons) which give a compression ratio of about 9.2:1 in a 4.6. Garry

Thanks but as the Thor is a common rail system, if the injectors are fired by banks rather than individually how do you stop fuel being squirted into non firing cylinders in the same bank? Would seem a big waste of fuel - this is what I understand Megsquirt V8 is doing - modifying MS1 so that it will fire sequentially. Through the brains trust a while back I was told categorically that MS1 will run a Thor engine so i acquired the relevant manifold etc - but now I am told that it is not quite ready (Nige and his development mate). If I had been told the truth I would have acquired Gems or 4CUX system. People who think they know all MS say it will run all RV8s but that is not true just at the moment - they do not seem to understand that Thor is common rail and full sequential not batch/bank firing like older systems. Read Nige posts above. I have posts on forums on three continents and on MS dedicated forums and have not come across one person running MS on a Thor engine - I have heard of some but not one person who has a MS Thor engine has posted up their experiences. If you know one get them to post up what they have so I can get real time advice. Anyway in view of all the conflicting and simply wrong information I am not going to go with MS the Thor at this stage. I believe the original Bosch Motronic can be modified to run away from its parent car in cars like TVR and Morgan and kit cars so am now looking at this. If this draws a blank I will buy a Mega Jolt or basic Megasquirt from a authorized MS dealer in the US where prices are about half they are in the UK and either put carbs or 4CUX on the engine. The other option is to get a manifold for a Holly carb and put the new Holly self learning self contained injection system on it - does everything MS does without the mucking around. In the future, once MS systems are fully proved and tested in the market I may revisit then but for now it is not going to happen. Thanks for all the input. Garry

My understanding that will not work on a Thor due commonrail and sequential injection - no banks A and B. But I am still learning. Many people providing advice are providing advice related to Gems or 4CUX and not Thor - hence I am getting confused.

Sorry getting mixed messages about the MS ECU - I understood from Nige that a modified MS1 is not yet fully developed. I am totally confused on what is on the market NOW that will run a Thor. I appreciate the difference between the just an ECU and a full kit. If someone with a fully functioning Thor on Megasquirt of any type would come along and explain what they have etc, I would appreciate it. Thanks

But as you indicated earlier - the MS1 system is still under development where the MS3 is already there and is very cost effective from recognised US suppliers compared to UK suppliers - the whole topic seems awfully confusing and I am just trying to understand. Thanks

If you were able to advise which model - that would be great. Cheers Garry

On paper the MS3 ECU could runs a Thor injection system - why isn't Megasquirt V8 using this version. Anyone used it on the Thor??

The block is a top hatted 4.0 Thor engine that has a 4.6 crank, and conrods. I have also have a couple of sets of Thor manifolds, injectors, rails and loom. Teh only sensors I have at the moment are on induction system. Garry

Mike - that is exactly what I was looking for - an actual conversion rather than a hearsay conversion. We do not have the Sherpa in Australia but I do remember driving around in them when I lived in the UK. I will do some further research on this and see if I can source two from breakers and get them imported. I was a member of the 101 Club but they were not really providing much support for foreign members and their spare parts process was woeful - they still owe me some small parts from about 4 years ago that I have paid for - decided it was better to pay more at other suppliers and get the goods rather than paying less and never getting them. A number of other Aussie members have also left the club for similar reasons. Thanks to every one else for your comments - as indicated the 101 steering is basically the same design from the relay to the wheels but nothing is common with any other Landrover - it is much more heavy duty than those. Likewise there has been a few suggestions to use electric steering etc and thanks for those but I a not looking a prototyping something that has not been done - hence my interest in those who have actually done it. If anyone has versions that have been installed in 101s that do not involve cutting the chassis please post. Cheers Garry

Thanks Nige - I wished I had the above information earlier as I did not have an injection system and on the advice of people on here and on other forums have acquired the Thor manifold, loom and injectors. The overwhelming advice was that out of carbs, 4cuix, Gems and Thor was that Thor was the way to go and "just Megasquirt it" and that seemed logical as a Thor Megasquirt seemed to exist. Unfortunately forums send out mixed messages. I might drop the Thor idea, distributorless ignition and Megasquirt all together and just go big jetted carbies and electronic dissy - to be honest it just seems too hard and expensive to go with Megasquirt. Thanks Garry

Not at all - just frustrating to be seeking information on a topic you know little about and there is irrelevant information but that is what forums are like.

Pics will not be much good as most of the system I am taking about is hidden - basically from the steering relay to the wheels it is the same basic system as any other series vehicle. The steering column with the steering box attached at the bottom is nearly vertical and has a steering arm and tube that goes back to the steering relay. Hopefully some pics below but will be hard to interpret if the system is not know, I am not after suggestions on how to do power steering and I have no intention of experimenting. I am after someone who has actually done it on their 101 without cutting the chassis. There are plenty of people who know someone who has done it but with one exception I have not found anyone who has actually done it themselves. The first pic is the steering arm attached to the steering box and the steering rod that goes back to the steering relay (steering box bottom right corner). The second pic is taken from between the chassis rails and shows the same as the first pic but from the opposite side. The last pic is the steering box. The steering column is at the top. The output side of the steering box is obscured by the chassis. Had to add pics as thumbnails as Photobucket is down. Cheers Garry

Looks like the thread has gone downhill pretty quick with rubbish posts that add nothing to the topic. However thanks to those who posted early as these provided the sort of information I was looking for - in particular Nige who posted information on competitors as well as his own organisation - I appreciate the input and later when I have my engine built I will be in contact direct. One question though for Nige and Bobtail84 - Nige's website seems to indicate the Thor version is up and running but your discussion here seems there is a little more testing/building is required. Can you clarify its current status. Thanks Garry

Other than Megasquirt - V8 who else sells Megasquirt for Thor engines. Thanks Garry

Thanks for that - on the 101 all boxes need to be mounted on the outside of the chassis or else a couple of right angle boxes are needed to take the steering drive to the steering box. The RRC, Disco and Defender boxes can be mounted on the outside of the chassis but it needs to be cut as per the following pic - something I do not want to do. I need to double check the P38 steering box when I can get hold of one. The Vauxhall Omega B is our Holden Commodore but here it runs a rack and pinion system not a separate steering box. Thanks for the leads. Cheers Garry
