Gazzar Posted June 7, 2020 Author Share Posted June 7, 2020 No one. You just assumed. I've decided not to worry about the zinc paint. Apparently most modern oils don't have zinc, as it messes up the catalyst. I'm not fitting a cat to this Landrover, for the use it will get, I see no point. Zinc is helpful to running in an engine.

Gazzar Posted June 7, 2020 Author Share Posted June 7, 2020 Next up will be finishing the top. Then the distributer/cam position sensor planning. I also need to think about a stand so I can fit the flywheel, is it necessary? Quote Link to comment Share on other sites More sharing options...
Landrover17H Posted June 9, 2020 Share Posted June 9, 2020 (edited) If I read it right, and I'm sure you're more aware than me, but yours might well be a first? An MJ'ed 2.25 has been done a few times, and searching shows up a few 'projects', yet I don't think a full EFI 2.25/2.5 has ever been done. There's V8s to the point of boredom, but no 'In the flesh and running' EFI 2.25/2.5. Edited June 9, 2020 by Landrover17H Quote Link to comment Share on other sites More sharing options...
Gazzar Posted June 9, 2020 Author Share Posted June 9, 2020 Don't know. I expect it has been started, with throttles/ injectors out of 90s eurobox etc. I'm trying to plan the next stage, and mesh that planning with the lightweight build. I think I'll build up the tanks, bulkhead, loom etc, with no paint prep. Get the engine running, then strip back and do the pretty stuff afterward. 1 Quote Link to comment Share on other sites More sharing options...
Gazzar Posted June 9, 2020 Author Share Posted June 9, 2020 I'm thinking of getting something like this as a intermediate tank to feed the injector. Mounted on the pass side of the bulkhead in place of the tool box. Fed by the lift pump, returning to the tanks. Quote Link to comment Share on other sites More sharing options...
Landrover17H Posted June 9, 2020 Share Posted June 9, 2020 I have tell of a supercharged 2.25 as far back as 1973, I have the list as: 1) Not less than four MJed 2.25s (I think Roland at ACR did kick-off). 2) One turbo project sits on Youtube. 3) Two with steam-engines for comedy-effect. 4) One natural-gas 2.5. 5) Heaps of LPG conversions, sadly these are on the wane. And you with full EFI. Reckoning on you as a first. Quote Link to comment Share on other sites More sharing options...
Gazzar Posted June 9, 2020 Author Share Posted June 9, 2020 http://www.melsteve.plus.com/LandRover/index.html ? Not explored this in ages, might be relevent. Quote Link to comment Share on other sites More sharing options...
Gazzar Posted June 9, 2020 Author Share Posted June 9, 2020 Surge tank ordered, and the main loom. Update: Loom could be ten weeks!!!!!! Plenty of time to get a starter and alternator, and figure out the split charge systems. Quote Link to comment Share on other sites More sharing options...
Gazzar Posted June 12, 2020 Author Share Posted June 12, 2020 I've one or two more jobs to do on this before I start on the trigger wheel. Paint will feature. But first an experiment. With acid. I'm putting the cast steel coolant system from a series into this engine, and eBay delivered some candidates. Which were a bit rusty, so time to try citric acid. I'm looking for something to clear out the water galleries in the block, but am reluctant to just lob some untested stuff straight in. I'll check the progress in the morning, if all I've left is rusty sludge, them I may have the concentration wrong. Quote Link to comment Share on other sites More sharing options...
Gazzar Posted June 12, 2020 Author Share Posted June 12, 2020 I've changed my mind on the rocker cover, the series one is too nice to paint, and, as I've also found the 90 breather, I'll fit the 90 rocker as well, happy to spray that mod blue. There's another benefit, the valve clearances on the ACR camshaft are smaller than standard, thus the little label screwed to the rocker cover has the wrong information on it. I've a few other bits to paint. Quote Link to comment Share on other sites More sharing options...
Gazzar Posted June 12, 2020 Author Share Posted June 12, 2020 I'll do the intake manifold in paint. It's cleaned up okay, but would look really well in blue. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted June 12, 2020 Share Posted June 12, 2020 Oxalic acid is great stuff, only eats rust, leaves the steel clean. Excellent for cooling systems. 2 Quote Link to comment Share on other sites More sharing options...
Gazzar Posted June 12, 2020 Author Share Posted June 12, 2020 Chemistry, magic to me, to be honest. Gave up when it got to ionic bonds, beyond me. The citric stuff is fairly safe, so I think I can't mess it up, but if the rust doesn't shift I'll check out the oxalic acid. Or boil the citric acid.

Gazzar Posted June 13, 2020 Author Share Posted June 13, 2020 Change of subject. Can I use the standard coolant temperature sensor for megasquirt? Will it interfere with the normal gauge and vice versa? I ask, because now is the time to drill and tap for new sensors. Thanks. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted June 13, 2020 Share Posted June 13, 2020 Use a separate one, a Rover V8 wouldn't sensor wouldn't be bad, as we all know the configuration for it... A gauge sender and ECU sensor are two different things, the ECU sensor will normally have two wires going to it so you get a decent reference voltage.

Gazzar Posted June 13, 2020 Author Share Posted June 13, 2020 I'll have to tap into something to get a reading. Maybe the heater take off? Thanks, I'll order one up today. Are there any other block sensors or similar that it would be smart to look at now? Cam and crank I think I have a solution for. Quote Link to comment Share on other sites More sharing options...

Not sure if you’ll need it with your kit but the only other one that springs to mind is possibly an air temperature sensor. And a MAP sensor...?

Gazzar Posted June 13, 2020 Author Share Posted June 13, 2020 The map sensor, I think that could go on one of the untapped bosses on the manifold. Could the air temp sensor go on the series swan neck? Quote Link to comment Share on other sites More sharing options...

Could the air temp sensor go on the series swan neck? The last one I fitted went on the inlet manifold but that was for a Cosworth engine in my Capri and there was already a tapped port for it. I believe as close to the inlet as possible would be preferable. Remind me what ECU you will be using to run the engine, is it MS? Quote Link to comment Share on other sites More sharing options...
Gazzar Posted June 13, 2020 Author Share Posted June 13, 2020 Micro squirt, probably. I looked at the speedaudrino but an ECU engineer I know looked at one, he had concerns about its robustness. Plus, I know a megasquirt expert visits here on occasion..... Quote Link to comment Share on other sites More sharing options...
Gazzar Posted June 13, 2020 Author Share Posted June 13, 2020 Is this the V8 sensor? I'll probably buy from one of the Landrover on line shops. Quote Link to comment Share on other sites More sharing options...
Gazzar Posted June 13, 2020 Author Share Posted June 13, 2020 Fitting it will be fun. There's a number of options. I like directly on the head, where the 2a sensor was. Here is easily a accessable: Quote Link to comment Share on other sites More sharing options...
Gazzar Posted June 13, 2020 Author Share Posted June 13, 2020 But those options involve a risk I'll wreck the head. So would this work? Beside the heater take off? Quote Link to comment Share on other sites More sharing options...

Landrover17H Posted June 13, 2020 Share Posted June 13, 2020 Don't know about that, but Series cooling linkage to 17H, you'll find there's two flavours of that 3 bolt pipe manifold jobby on the 17H. If you're lucky you've already got the one with the extra port. Standby, I'll dig out some pix. Quote Link to comment Share on other sites More sharing options...
