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 :-)
