MWR Stage 2 camshafts are a mild-to-midrange option for the Toyota and Lotus 2ZZ-GE engine. Upgrade for significant power increase on stock engines or built engines revving to 8600rpm or less. Naturally aspirated, supercharged, turbocharged engines can benefit from this camshaft upgrade, with increases in midrange torque and helping to fill in that 4000-6000rpm gap.

These cams provide significant gains on a stock ECU but benefit from a tune. Aftermarket forced induction guys, definitely do a re-tune to maximize your gains and optimize VVT and fuel mixture settings.

Q: How does the camshaft lobe, lift & duration affect power?

• The 2zz starts out with fairly big cams. The aftermarket cams add lift and duration to increase performance from the midrange up. Ultimate power gains are pretty similar between MWR and Piper; the difference is in the small lobe, where Piper went pretty conservative for a good idle and MWR went bigger to maximize gains in the 2zz’s notoriously soft 4000-6000rpm midrange.

• Checking/adjusting valve clearance during installation is recommended
  
• Upgraded aftermarket valve springs art required to avoid coil bind.
