I wouldn't advise going over 89mm in an L18W, although I have seen them at
90mm they have problems with cylinder wall cracks due to flex at high
stress. I am boring my current block to 88mm (when I get the pistons made
up) which should have no flex problems I hope. Z22E pistons and L16/24
rods are a good combo, and converting to Chevy bolts is not difficult.
Datrats has a set of 87mm arias forged pistons with 29mm compression ht and
3mm dish which would be a good combo with L13 rods for hi-po turbo, or
L16/24 for normal turbo use. I am not a turbo freak so maybe some of the
other blokes could assist with the calcs better than I.

Subject: L18w blocks
Whats the maximum bore size for an L18w block? Can you go as big as 88
or maybe 89? I'm considering Z22 or Z24 pistons with L16 rods or is it
only L24 rods that came with 9mm bolts? While i'm at it any ideas on
maximum distance for an effective quench deck. This is for a turbo set
up.
