    Sourced a full imobilised loom, ignition barrel, keys, ecu etc from a micra. Also, instead of an engine temp sensor for ecu, will just use a potentiometer with a resistor in line to mimic the resistances shown by the temp sensor, and then manually adjusting it (a bit like a manual choke!) Rather than modifying the head or block

    I'd never do the mapping myself... I'd pay someone to do it. I've seen people spend 8k diy'ing and breaking and learning when they could have had it professiinaly built for 4k. Mapping as a learning excercise doesn't interest me, and I know a VERY good mapper. The donor engine also has chain driven cams, and there is no timing issue having the timing run off the dizzy. Having the crank sensor on the crank pulley looks ugly imo, much neater in the dizzy. Fitting the nissan engine management in stock tune to start with gives me a big initial saving (and I can swap between micra and almera ecu's to get the best spark/fuel map, with 4 different ecu's; 1.0, 1.3, 1.4 and 1.6). As you said, I can choose megasquirt if it is more appropriate, but I'll leave that decision to my tuning man.
  3. Wear on the inside edges is more likely to be excessively negative camber, or possibly under inflated tyres. Ensure that your camber is no more than -1 degree for road use, toe is between =/-0.1 degrees, (toe out gives better turn in grip but the car tends to wander at speed in a straight line, toe in gives better straight line stability but compromises turn in grip) and that you perfrom the checks with all four tyres correctly inflated and ballast the car ONLY according to normal driving weight, e.g. if 99% of the time it's only you in the car, only ballast the front drivers seat.

    I noticed those too, hopefully they won't be gone before the Herald materialises!

    Hmm, chain driven supercharger?

    Well I think you could get a rotten donor micra for £100, maybe £100 for the head to be modded for the temp sensor, then you could just rehone and re-ring for the low comp pistons. £100 for the inlet adaptor, and maybe £300 for the inlet manifold and fuel rail to be modded, and £50 for the lamda sensor boss to be welded. I'm fortunate I have access to all the tools and equipment I need at work, so i'll only have to pay for the donor vehicle (which I'll break for parts and recover some money off).
  7. I don't agree with this, I use an alias to protect my privacy. I don't want people googling my name and being able to track my forum habits and see everything I've done to my vehicles.
  8. Hello everyone! I was a member many moons ago under Solo_Andy1989 on the old forum with a 1500 Spit. Anyway, I'm just about to finish my modern practical apprenticeship and so I've been looking at 13/60 Herald Saloons as a gift to myself if they give me a job after. My current car as it stands is a Nissan Micra, with a 1600 Almera engine and brakes and an electric water pump and home made pump controller (A bone stock looking granny spec '95 micra that does 0-60 in 8.3 seconds and can beat a Golf Gti makes for much hilarity). Nissan engines of this era intrigued me for a few reasons: 1. They use a distributor. The ignition coil is built into the distributor cap (although an external one can be used with a bit of a play), and the crank position sensor for the engine exists as an optical disc with slots where the points would be on a lucas dizzy, under the rotor arm. 2. They have a throttle assembly with an air flow sensor, throttle position sensor and idle control valve all built in. 3. The ECU's come both with and without imobilisers, and for £500-£600, you can have a reprogrammable daughterboard fitted and the ECU retuned for power, economy, torque etc etc 4. The ecu RPM output is sufficient to operate a Lucas Tachometer So, my plan is thus: Modify the top half of a Nissan 1.3 dizzy to fit the bottom half of Lucas dizzy Modify single carb Herald 13/60 intake manifold to take Nissan 1.3 injectors and fuel rail Manufacture an adaptor plate to fit the Nissan 1.3 (45mm) throttle/sensor assembly to the Herald 13/60 intake manifold Source second herald 13/60 head, rebuild modify to take a Nissan 1.3 coolant temp sensor Modify Herald 13/60 4-2-1 to take a Nissan 1.3 exhaust/lambda sensor Modify a Nissan Micra 1.3 engine loom to fit a 13/60 engine Modify a Nissan Micra 1.3 Immobiliser loom and ecu and fit under a 13/60 dash Modify the throttle cable accordingly Remove crank driven fan and fit electric rad fan (controlled my the engine ECU) I would expect this to do a few things: 1. Give me a fairly tidy and inconspicuous electronic fuel and ignition system with cheap, readily available parts. 2. Produce no extra power 3. Be infinitely more reliable than carbs and points 4. Make the car harder to steal It would also give me the perfect starting point for a serious power build. The idea would be to, after the novelty of fuel injection had worn off: Source second 13/60 engine bottom half, rebuild with US spec low comp pistons Fit larger 1.6 injectors Fit larger 1.6 throttle/sensor assembly (50mm) Fit Eaton M24 supercharger from a Polo 1.4 TFSI Fit 4-2-1 exhaust manifold Machine/source new crank pulley to gear for approximately 10psi Send to a man for tuning to approx 90hp Fit Vitesse brakes Lower car 1" all round Basically make it a little more torquey without resorting to changing the engine/gearbox/propshaft/diff etc like I would with a 1500, or the extra weight of a 6 pot. I considered fitting the Nissan 1600 engine, as it was originally designed for longitudinal mounting, but figured that wouldn't involve nearly as much tinkering! Any suggestions or (constructive) criticisms welcome :-) Andy
