Thorough testing At Monkeywrench Racing we believe in testing everything that we sell. That’s why we spent hours testing and tuning our shop’s 2000 Celica GT-S with Piper’s new 2zz camshafts. With these results in hand you can decide which cams best suit your goals for your Elise, Celica, Matrix/Vibe/Corolla, or other 2ZZ-powered vehicle. Bottom line is if you are running a stock engine and stock ECU you’re much better off with the stage 2 cams. If you’re running the Power FC you’ll enjoy significantly more midrange and some additional top end power from either grind. If you have a built engine, ported head, high compression, revving to 9k, etc, you’ll probably want to run a Power FC / stage 3 combination for maximum power.

**You MUST run upgraded aftermarket valve springs with these cams to avoid coil bind. 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.

Reading the graphs: Green is horsepower, blue is torque. Both are measured at the wheels, horsepower is corrected via the SAE standard but torque is uncorrected. The solid line is the first of the two parts listed, the dotted is the second ie. if it says dog vs cat, dog would be the solid line and cat would be the dotted line. Got it?

PCI-01-ST2vsSTK-StockYou can see here that the stage 2 cams, even with the stock ECU, provide a huge improvement in power delivery around the VVL engagement point making the 2ZZ a much more drivable and responsive engine. Idle is good and low end torque does not suffer.

PCI-02-ST2vsSTK-PFCAdd the Power FC and gains are even more impressive.

We work very hard to make sure test conditions don’t vary but I think this one is a case of the stock ECU being run while the car was a little on the cool side and the PFC being run when the engine was a little bit hot. The PFC will have a little more advantage than you see here.
