I am more concerned with the wear on the rings and liner. Not the bearings.

The rings (ductile iron plasma moly inlay top ring and premium iron taper faced rings) and stock K24 liner (bored to 87.5mm) are doing fine at 8000rpm, not sure how long it'll last though. We'll find out when I open the engine again next year.

Tony does that mean your car is up and running? What times you pulling?

Should see the track sometimes in September. Queensland raceway that is :P Not willowbank hehe

I'm using the PRB manifold until the IPS manifold arrives, should be able to get close to 280whp with the IPS intake manifold. I ordered that manifold back in August last year and it's still in production..

I'm taking out the VTC system this week, going to replace the VTC stuff with adjustable gears so the cam angle is locked and no longer affected by oil pressure drop during high G corners. Hopefully I'll be able to make it to the next SAS.

Post a video for me! I want to hear the k24a at 8000rpm in all it's glory! :thumbsup:

How much does the pressure drop by in high G corners? Did you go baffled sump as well? How much did that cost?

Waiting for you.... :thumbsup:
Add oil

some 99mm stroke can rev pass 10k rpm with the right combo of oil pumping system and rod/piston combo.
