> yeah the injesctors are black tops, they flow the same as the blue tops
Blue tops spray in a single cone. Black tops spray in a dual cone pattern.
Otherwise same sameness.

I think FJT distributors now do a longer conrod which recovers a lot of the lost compression ratio.
If you've access to a machinist, it's supposedly possible to rebush B18 rods from 21mm to 19mm piston pin. They are slightly longer than d16 rods and are another route to recover the lost compression ratio.
I THINK it may be possible to source YCP Vitara pistons with a 21mm piston pin.
YCP make Grand Vitara pistons which are 75mm, 21mm wrist pin. But it's a long time since I looked at that stuff.
nothing wrong with forged pistons though.
