well, i have/had new timing chain and sprockets.. fingers crossed 
yup, from this head. it gets a little confusing with diff ratios and all that, but a rough back calculation from the 86kw motors making 55kw gives me
peak torque of 103Nm at 4600rpm
max power of 100hp (and 86Nm) at 8000rpm
AFR goes from about 11:1 at 4600 to about 12.3 at 8000rpm and is reasonably linear. i have a fair way to go there, but should be easy with the injection (Megasquirt  )
torque curve is pretty much linear between those points. i honestly think output is a bit lower than that but it's hard to tell without and engine dyno.
but even so, 103Nm from 1.3L is a bit lacking. i am hoping for peak torque around 120Nm with the injection
i have a 4KE setup atm, but have just organised to buy a 7KE setup as well not sure which will go on first
probably 4KE, but 7KE looks better for any boosted application.
i do want to try both to see what difference there are, especially in regard to throttle response and high rpm figures.
