Conrod upper 381g
Conrod lower 119.2g
Nuts 14.6g
Total weight 927.3g

Lots of stuff coming in!
The cutest package from Thailand:
Cute box contained connectors for Toyota coil on plugs. Most likely fake as fuck but hopefully they work enough.
Pistons, again.
Arp hardware – studs and bolts. No cat this time.
Engine management unit from MaxxECU, with long loom, lambda sensor and stickers!
The turbo – BorgWarner EFR 6258. Hardware kit needed.
Toyota coil on plugs (dirty and used) – look how the last one is bit short and stubby compared to the rest of the coils. The last one is from Yaris and the long and skinny ones are from Lexus. Funny thing is that I ordered four Yaris ones but got three Lexus coils and one Yaris.
Not going to complain, because the Lexus coils seem to fit pretty well into 4A head. 🙂
Lexus coil part number – 90919-02246
Pistons arrived! They’re Wiseco K506M815, 81.5mm (+0.5mm) oversize and  with rings and other small bits.
Cat claimed the box when I presented all the stuff to her.
With the cat in the box there are ARP head studs and ARP flywheel bolts.
Seems that I have reached the point where there is nothing to take apart anymore!
One of the pistons (the one that had a ultrasonic bath) taken apart and measured – maybe bit too HDR-ish photo 😀
The new oil pump, this one with 74mm gears. I found some info about how the new dry pump should be primed with grease or assembly lube, but I think that is for later.
Finally, I’ve at least primed the engine block! Got all of the paint stripped, the block cleaned and greaseless and then painted with 2-component epoxy primer (which is actually fine for only coat, but maybe light silver top coat…?)
