G102 Engine Swap

Installing a 1.6L EFI engine from a 1994 Daihatsu Applause into a 1.3L EFI 1990 Daihatsu Charade.

The beginning

One completely stock-standard G102 Charade. Purchased for the princely sum of A$2000.

Engine bay, containing standard HC-E 1300 EFI (with blown head gasket).

The swap.

All wires and pipework disconnected (and LABELLED! LABEL EVERYTHING!), fluids drained, battery, radiator and air filter removed.

Out comes the old HC-E!

Swapping all brackets, manifolds, sensors, clutch and gearbox between engines. The engines are almost identical, and everything bolts straight on. I used the Applause inlet manifold, throttle body, fuel rail and injectors. An Applause pressure plate and driven plate were used on the Charade flywheel.
I'm the one on the right, Gary is on the left. We're greasing the clutch throw-out bearing.

Next day - the assembled HD-E 1600 EFI goes in.

Connecting everything, below and above. Did I mention that I LABELLED EVERYTHING so I knew where to connect it? I kept the Charade's ECU and wiring loom.

Everything back in place. Looks just like the old one :-)

The clean-up

The only glitch was the injector leads. The plugs on my Charade loom wouldn't connect to the Applause injectors. The differences between the Charade plug (white) and the Applause plug (grey) are small but significant.
Easy fixed: one Applause loom for spares, snip snip, yellow to yellow, red to red, solder and tape. The hybrid franken-loom is born.

Bonnet back on, fluids replaced. The car had 216,135km on the odometer - the engine came out of an 80,000km wreck.

The Aftermath

While I had the engine bay empty, I noticed some pretty serious cracks in the strut towers and chassis rails. Apparently, this is a known problem on G102 Charades. So, I had them welded up before I went for roadworthy.
While I was running around getting the little bits and pieces fixed up for roadworthy, a truck pulled out of a driveway in front of me. On a wet road. I'm glad I had the chassis welded up, or else I may have had a HD-E Applause engine in my lap. We got the crumpled wreck off the road with a forklift (I crashed just over the road from DaiAuto wrecking yard, which was convenient).
Needing a new car urgently, I ran out and bought another G102 - a blue '89 model - with a working engine, this time.
Several months later, with messy legalities finished, I was the owner of a blue G102 (in good working order), and a red G102 (written off, but with a nice HD-E in it), and a cheque for the pre-crash value of the red one.
If I had the space to keep the red wreck as a parts car I would have (and done the engine swap myself again)...but I didn't.
So I collected all of the best bits into the one car - I got DaiAuto to swap the HD into the new Charade - their labour in exchange for whatever was left after I drove away.
As of last page update, I'm still driving my 1.6L Charade. I thoroughly recommend the upgrade.
