hi all
ive got a xr3i 1600
that im turboing at the moment
to just try a few things out.

i need to lower the compestion
i havnt got a set of rs pistons yet
as they are fucking hard to get hold of in
new zealand.

so what im wondering is there any other way to lower
the compretion ?

will consider any ideas at the moment
apart from skimming the pistons

thanks
