Re: Thor conversion

Yes and no - with no local support MS3 is too much hassle - the documentation is crap and the forum is not the greatest so I am back on carbs at the moment and will buy an off the shelf ECU and then put the Thor back on.

Re: Thor conversion

I assume you mean this barb in the centre upper of this pic https://live.staticflickr.com/65535/49163138036_2275d95ebc_k.jpg 081 On my old 3.5 manifold there was a similar barb that was connected via a small rubber pipe to a similar barb in the top radiator tank - I assume to allow air to escape the...

Re: Megasquirt Settings

Each time I have asked for an initial map on a couple of forums I was told no - I have to do my own. MSers seem loath to share this sort of thing.

Re: Ignition module wiring

Well the first thing is I would not use a system that has the ignition module on the dizzy. In RV8 it cooks and develops dry joints and often failure to start - get a dizzy or a modification kit that has the ignition module located away from the dizzy - early Disco V8s had the ignition module as you...

Re: MOST FOUL RESISTANT PLUGS

I have a similar problem in another vehicle - in my case the carb is running a bit rich and over a couple of days carbon builds up on the spark plugs with a commensurate reduction in performance until the engine will not run - there is no spark at the spark plugs so mimicking an ignition problem whi...

Re: Lucas 14CUX on a 4.6 ?

Just a minor point - the 4.6 piston gudgeon pins are thicker walled than the 4.0 pistons (outside diameter is the same but the walls are thicker). Now the 4.0 gudgeons are plenty strong enough but as I had both the 4.0 and 4.6 pistons, I had my machine shop change the gudegeons in the 4.0 pistons ov...

Re: Lucas 14CUX on a 4.6 ?

There is no "little jiggery-pokery" required - they simply go straight in and you can use standard heads and head gaskets. No modifications are required. Standard 8.3:1 4.0 pistons produce a compression ratio of about 9.5:1 in a standard 4.6. I have a a 4.0 engine block, 4.6 crank and conrods and lo...

Re: Lucas 14CUX on a 4.6 ?

I didn't I just happened to be lucky enough to pick up a factory reconditioned block for a very good price. New pistons and rings too - but they're 4.0 type - and one of the new pistons has been cracked due to very poor storage. Ok I misunderstood as in your original post you said "I've got a LR re...

Re: Lucas 14CUX on a 4.6 ?

I know of a 4.6 that runs a 14CUX injection system and standard ECU - the standard ECU programming has enough scope to provide enough fuel with the 14CUX injectors for a 4.6. Note that the 14CUX has a smaller intake (and throttle body) than the 4.6 Thor system so may be a little restricted at high r...

Re: Zenith Stromberg CD 175 Needle/Jet modifications

So I guess no one has an idea = other than Pauls suggestion to buy the book.

I was hoping that someone had done it.

Well it looks like I have done my $$$$ - sensor installed but not yet connected electrically. I guess I will use until it fails and get something else. :cry:

Zenith Stromberg CD 175 Needle/Jet modifications

I have got 2 Zenith Stromberg CD175 carbs from a 3.5 RV8 in a RV8 4.6 - they run the engine Ok but do not have needles/jets suitable for the larger capacity engine. Can anyone outline what mods such as larger needles and jets are required to be made to the carbs for the larger engine. Yes I know the...

Re: 4.6 RV8 rough power and trq estimate

Correct but if you are not able to do better than that in any configuration you might as well stay standard.
