What do these numbers mean? 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.

Installation is easy, taking only 2-3 hours for someone familiar with these engines. We recommend checking valve clearance but it usually does not require adjustment. Use the OEM recommended valve clearance and torque specs during install. Timing is simply set using the stock timing marks, no degreeing is needed.

If you are running a stock naturally aspirated engine and stock ECU (tune) you’re much better off with the stage 2 cams.

If you have a built engine, ported head, high compression, revving to 9k, etc, you’ll probably want to run stage 3 for maximum power.

Supercharged? Stage 3 tends to work best with no penalty in the midrange.

Turbo? We often stick with a stage 2 cam for turbo builds since there is less need for huge duration and you don’t generally need to rev as high.

**You MUST run upgraded aftermarket valve springs with *any* 2zz aftermarket cams to avoid coil bind. MWR springs are the best choice for those revving to 9000 or less. Ferrea dual valve springs work great to 9500+ but cause significantly faster valve and seat wear. You can optionally upgrade your retainers to titanium and while you’re at it, replace those problematic stock 2ZZ valves with MWR’s superior stainless steel valves or Ferrea stainless/inconel valves.

Here are some dyno graphs demonstrating typical gains. These are honest dynos of both setups running at their very best. No sandbagging. You can expect similar results adding these cams to a 2ZZ in your Lotus or any other 2ZZ-powered car. The setup on the test car was extremely basic which is why the numbers read lower than the results we have posted elsewhere on the site for the Piper cams..

  2. Safa Misaghian

    Best modification ever for 2zz..exelents results with stock ecu, and outrageous results with pfc tuning..best purchase ever..

    Great quality..
    Check with your tuner as the stage 3 had to much lift for my turbo setup and couldn’t use lift.

    MWR note: thanks for the feedback! We recommend stage 2 at a maximum for most turbo setups. The larger small lobe improves spoolup nicely but going too big (stage 3) especially with a small or mid size turbo can make tuning difficult.
