Stock D16 Rod Length: 137.00mm (0.067" bellow deck)
FJ Custom Rod Length: 138.63mm (0.003" bellow deck)
D16Z6 Head Milled ~3mm + FJ-R Rods = ~11:1 Compression....
3mm is a bit extreme. I know close to 2.5mm can be done on the Z6.
Lost the exact #'s to get to the quench pads on the Z6, but I know it's like 2.5mm...
Anyways, back to topic. Do Vitara builds stand up to 400whp+ becuase the low comp (and they make power at high rpms, and at high rpms detonation isn't as likely, something about spinning to fast for detonation to happen, blah blah) or are they strong enough to stand up to some detonation?
Not building a motor
yet. Researching different build ideas first.
