1Zs (up to 96) are common as muck and very cheap on ebay (£2-300 complete), but they are limited on tunability as the pistons are weak - 140hp max I'm told.
i only want around 120 -130 bhp as a max,
if you need only 120-130hp you can try to make your NA turbo
I know some 1Z whichs had 170-180 hp and everything is ok...
