hi, i talked to stewart w ralling and he said
the pistons would be good for 12 lb.( and i was running 15 lb for about 5
mins ) and stewart also said that it was
dentonation
i also phoned up a turbo place in nsw,
and he said it was dentonation.
the two pistons looked absolutely fine
, besides the cracked lands, no sign of any
other damage.
any ideas on how to
controll dentonation? the dizzy was modified for 15 degrees, with engine idling
and vac line disc, and a total of 20 degrees.
i have a inter cooler, would water inject be a good
idea?

Are you sure it was the boost, and
not the detonation, that broke the ring lands?

Does it have a set of extractors on it or has the
stand. exh mani been modified at all?? Is there a water feed running
from somewhere into the turbo?? If not , like adam said i doubt its a
T25/28 as the stand z18 used a T3 which is a complete diff bolt pattern.
They never came out with a T25 from factory....
As for the question
of the head ive had my head shaved 2 times on 2 different rebuilds and
it still runs up to 20psi no probs on the standard bottom end.As for how
much boost you can run that will depend on what injectors are in it and
how hot the air is thats getting pumped into it.
As for just bolting
a L18 bottom end onto it i dont see any particular point whatsoever.
Unless you spend money setting it up to handle a forced induction
lifestyle, and then u may aswell of used a z18 bottom end to start
with.
As for power mine made around 90kw@wheels@10psi in pretty
standard form. 176hp@wheels sounds like a crock of shit/attempted
selling point to me.

cheap/easy to find cause I'd be looking at replacing it. also he didn't
downgrade from a T3 down to the T28the motor had a T25 on it when it
came in from the importers, he upgraded it to a T28. I can't use a Z22
bottom end cause the car it's going into is only just over 800kg which
limits me to a 2L with forced induction. I have a spare L18
bottom end here, can I just bolt that under the Z18 head, instead of
going to the trouble of stripping the current one down to inspect
it. Dave
