I've also been looking at the locally available Daihatsu Sirion motors (1L). They are the EJ-VE engines from what I can tell.
Does anyone have any info on them?
The Australian market only had the 1.0 litre (3Cyl) model up until early 2001, when the sporty 1.3 litre model - known as the GTvi - was added to the line-up. At the time, the GTvi had the most powerful naturally aspirated motor available in its class, developing 101 bhp (75 kW; 102 PS) at 7500 rpm.
I do know you can pick an entire Sirion up for a few grand, so I imagine a half-cut would be good value, or you could flog the remaining parts and probably get most of your money back.
A friend bought a Sirion new in 1998 - it's probably looking forward to a rebuild now though, after 180,000kms in 12 years. Daihatsu = Toyota, so they are reliable and parts support is top notch, but like most small engines they don't last longer than about 10 years without major work.
According to http://autospeed.com/cms/title_The-Daihatsu-Three-Cylinder-Engine-Guide/A_2968/article.html
- an Australian site:
Sirion and Cuore’s EJ-VE 1-litre three which runs DOHC, four-valve-per-cylinder breathing, a 10:1 compression ratio and EFI. It appears that variable inlet cam timing appeared from late 2001. Unfortunately, there’s no turbocharger and you’ll have to put up with its ho-hum 41kW and 89Nm.
I think the trick would be to find a GTVi variant which some sillybugger has shunted or lift-off oversteered himself into a parked car with and measure it up.
