GENERAL XRS INFO

Engine Type: 2ZZ-GE 1.8L I-4 with VVTL-I (Variable Valve Timing and Lift Intelligence). The 2ZZ-GE engine was developed by Toyota in collaboration with Yamaha Motorsports Japan (Yes, Yamaha as in Yamaha motorcycles).
The 2ZZ puts out close to 100 HP per liter of displacement and has one of the best power-to-weight ratios in its class. The XRS does not have an electronic DBW (drive by wire) throttle system like the 05-08 Corolla CE, LE and S have now primarily to maintain a quick and instantaneous throttle response by using the mechanical cable driven throttle system.
The 04-06 Matrix XRS and 05/06 Corolla XRS 2ZZ-GE engine has been detuned to deliver more midrange torque as compared to the 03 Matrix XRS/Celica GT-S 2ZZ-GE versions. As a result, the re-tuned 2ZZ-GE engine achieves 130 ft lbs of torque @ 6800 rpm in Celica GT-S/03 Matrix XRS 2ZZ-GE.
Also, the 2ZZ-GE engine and 6-speed transmission were licensed to one of the best roadsters ever developed... The Lotus Elise



VVTL-I or LIFT

What is this "Lift" thing that everyone’s talking about?
Lift is in the 2zz engines built by Toyota. It’s the 6200 to 8200 rpm range where the engine gets a sudden surge of power accelerating the car at a much faster rate. An approximate 40hp jump.
The 2zz engines are in the Toyota Celica GT-S and Toyota Matrix XRS. Lift is more lengthy in the manual transmission cars because they rev all the way to 8200rpms versus the automatic Transmission which only goes to an estimated 7900rpms before redlining. IE the engine cuts out and ceases to accelerate temporarily.

TIPS FROM PERSONAL EXPERIENCE

OIL TIPS:
Use 5W-30 Regular Toyota Oil and Filter until at least 8,000 miles. After that use 5W-30 or 10W-30 Synthetic oil for best results.
GAS TIPS: Use minimum of Octane 91 or higher (Octane 93 and 94 give better performance and smoothness according to many observations). Warning: DO NOTuse regular Octane 87/89 for a high revving engine with a high compression for the sake of saving a few bucks since apart from substantial power loss, it can cause pre-detonation where the gas might detonate in the piston chamber well before it was supposed and can cause the motor to blow up.
TRANSMISSION OIL TIPS: Good results have been found with multiple brands.
Newly found Neo Gear Oil, showing good results.
