There's a number of people been asking me to post up the details of my latest project. As my username suggests I've been shoehorning a 16v CG13 engine into my wife's Figaro.
It all started with a burnt out piston, Figaro parts cost a fortune and the 28mpg you get from a standard Figaro are reason enough for a change.
I picked up an insurance write-off K11 CG13 for £250. I bought the whole car because I know I needed the engine, box, ecu, loom, etc. Plus it was useful for robbing other bits when needed.
Out with the engine and box.
First trial fit in the Figaro.
This highlighted a number of problems with the engine and gearbox mounts, as well as the gear shift linkages. The major breakthrough was realising a K10 5-speed gearbox can be bolted up to a CG13 block. This makes fitting so much easier. The Figaro engine bay is a K10 engine bay so the left hand side and rear gearbox mounts bolt right in. The Figaro also share its floor pan and bulkhead with a K10 so a K10 pedal box and gear stick assembly also bolt right in. There is even the clutch cable hole already in the Figaro bulkhead but blanked off with a rubber bung.
K10 and Figaro pedal boxes-
Fitted-
Standard K10 gear stick assembly bolts to the Figaro floor pan. I made up a chrome outer sleeve from 15mm chrome pipe and a cue ball gear knob fits with the interior of the Figaro better than the standard black plastic. Note the centre console and front dash have still to be fitted.
Once I'd got the engine and box in roughly the right place I mocked up adapter plates for the Figaro air-con compressor and alternator. It might have been easier to use K11 parts but I didn't have a K11 air-con compressor and it was easy enough to make adapters to bolt them to the CG13 block. The power steering pump was a different matter and I could not make the Figaro one fit so I used a K11 power steering pump and had special hoses made up to fit the Figaro rack.
Block with mocked up wooden adapter plates. The power steering one was an earlier attempt that I could not make work. Once I was happy with the fit I made them out of 10mm Aluminum plate-
With the engine in the right position and the ancillaries mounted I could figure out how to make the right hand engine mount fit. I could have cut the original mount off the chassis and moved it forward to line up with the CG13 mount. However I had some aluminum plate left over so decided to make an adapter and use the original Figaro mount, turned through 90degrees.
The rubber metalastic mount is obviously directional so a trip to a mates garage and we pressed out the old bushing (by the way, it took 13 tonnes on his hydraulic press to press out), pressed out the CG13 rubber from its aluminum housing and pressed the CG13 bushing back into the steel K10 mounting but turned through 90degrees so I could use the mount horizontally. I used high tensile (12.9) countersunk bolts throughout.
Ancillary mount detail-
Next came the wiring which was a project in itself! Unfortunately the donor Micra had NATS, which I knew nothing about. A bit of reading up and I decided to source a non-NATS ECU. This added slightly to the complication because I now had to make a non-NATS ECU work with a NATS loom in a Figaro.
Thankfully I downloaded the NATS and non-NATS wiring diagrams from the forum and purchased the Figaro wiring diagrams, which I got printed out on A1 paper.
My advice when doing this is label everything!
The Figaro and Micra looms have a combination of 'engine' and 'car' bits to them. So I split the two looms as I wanted the 'engine' wires from the CG13 loom but the 'car' bits from the Figaro loom.
CG13 'engine' wires split out-
Figaro 'car' wires-
Two halves spliced together to make a new hybrid loom-
ECU mounted in passenger side foot well in place of original ECU-
The new loom hasn't been wrapped up yet just in case I have any problems.
The installation (nearly) complete-
I couldn't fit the Micra air filter box so decided to use the original Figaro one.
Not sure about the ducting though, bit too blingy for me, might have to paint it black!
