Hey guys, hope all’s well on your end of the world in these trying times.
I’m running a K3VET engine at the moment with a hybrid TD04, “Carrillo” conrods (yes they are knock-offs), ART Japan cast pistons and factory stock cast crankshaft.
I’ve been looking to rebuild the engine and I’ve already got in touch with Pauter for a set of 4x conrods and it seems like they’re the only manufacturers that do make anything for the Daihatsu engines at all. Maybe a little overkill but I endeavour to “legitimise” the engine and rid of the knock-off bits and pieces.
On to pistons, I realise that we do not have very many options especially when it comes to forging the engine (For cast, Nissan Micra / March K10 / 11 low compression pistons are a good fit however, and are but one option). I did however find something interesting from Wössner, part no. K9470DA (Fiat Abarth 500);
- Piston Size 72.00mm
- Compression Ratio 9.8:1
- Pin Diameter 18.00mm
- Rod Length 129.00
- Stroke 84.00mm
- Displacement 1368CC
- Application Turbo
- Comp. Height 26.80mm
There are 2 issues here however that I can see immediately;
- The stroke of the K3VET (according to the manual) is 79.7mm vs 84mm
- Compression height of the K3VET 20mm vs 26.80mm
Are these issues that can be overcome?
