Pretty confident its an arl unit (pd150) but guess we shall have to wait for the answer

Sure its an ASZ might have ARL bolts though. Not sure.

Heard its an abc

ZRT actually

BLT is best so ovbs tht 1

Had a google and its an asz!

I lose! But i also found that the arl has better head bolts apparently??

I love a good bacon lettece tomato

My engine is a mix and match of bits but basically at its core its an ASZ bottom end, a fettled PD130/150 head (they're all the same part anyway) and clamped down with the stronger PD150 headbolts.

Don't know why I have never lose coolant through head-lift. Is it good mapping? Not sure.

By the way - hybrid 2566vk turbo is seriously awesome, and mine isn't even setup right yet!

yeah the ARL head bolts are slightly stronger

not heard of head-lift before always thought the con rods would bend first
