Holden VZ V8 6.0L 5.7L L98 LS2 LS1

Please note: Tuning is done in the house on our dyno otherwise a remote custom tune can be organize.All figures are in rwkw (rear wheel kW) this is the power after it’s been transferred from the engine to the rear wheels. You may see other numbers used like HP, BHP, RWHP, WHP, PS, fwkW etc. Some figures are quoted at the engine and some are quoted at the wheels, if you get confused you can always use an online calculator or ask us.

VZ V8 Engine Performance
Figures will change depending on the engine on your VZ, so to do camshaft recommendations.

On the LS1 we recommend the 224/224@112 LSA (very lumpy camshaft)
on the 6.0L we recommend the 225/236@114 LSA camshaft.

These are generally as big as you can go without needing a high stall. On some VZ's the stock stall converter may be on it's way out so a high stall is always a good option!
We can supply and install high stalls for $2500 if required at the same time,
2500-2800RPM is what we recommend.
