Compression ratio is The differing power figures from through are due to changes in dynamometer testing procedures.

Due to noise regulations, Toyota recalled them for a flash of the PCM to up their output to classify them in the more lenient "sports car" noise category. The Corolla Compressor and Lotus Exige S add a supercharger with intercooler to achieve hp kWwhile the Exige R's supercharger increases output to hp kW. The addition of a non-intercooled supercharger to the Elise SC produces hp kW with a considerable weight saving.

The 2ZZ-GE was the first production engine to combine cam-phasing variable valve timing with dual-profile variable valve lift in the American market. The table below lists the specifications of the two camshaft profiles. The 2ZZ engine is also the only model in the ZZ engine family to use just six-speed manual transmission, as well as the only one to have been available with a four-speed Tiptronic-style automatic. These gearboxes were unique to this engine; since then, only a few Toyota engines have been paired with either a six-speed manual or a Tiptronic-style automatic and only one other engine, the 4GR-FSE, has received both.

The "lift" engagement and the engine redline vary by application. Consequently, it is impossible to "over-rev" the engine with the throttle alone; a downshift from a higher gear must be involved.

A typical "over-rev" can damage the oil pump, commonly disintegrating the lobe ring, resulting in damage similar to the picture at right. The oil pump is the Achilles heel of the 2ZZ, though incidents are rare and usually occur due to fault of the driver. Even the briefest period of oil starvation is usually fatal to this engine design. MMC is a reinforcement material composed of ceramic parts and fibers.

For the first few years of production, the engines were notorious for failing "lift bolts". This did not damage the engine, but would hamper performance as the high output cam profile was unable to properly engage. Toyota fixed the problem in late with a redesigned bolt that was installed on later engines.

Earlier engines with the problematic bolts can be fixed via a Toyota-issued TSB simply requiring the new bolt to be installed in place of the old one. The and newer Matrix and Corolla XRS models were equipped with smog pumps and have an extra hole above each exhaust port in the engine head and manifold where air is injected to achieve complete fuel burning before the exhaust stream reaches the catalyst.

The Toyota 2ZZ engine has an The 2ZZ-GE engine utilized a forged crankshaft that had five journals and eight balance weights. To reduce reciprocating mass and friction, the 2ZZ-GE engine has lightweight connecting rods which featured nutless-type plastic region tightening bolts.

The engine is equipped with aluminum alloy pistons with two compression and single oil control ring. The pistons were internally cooled by oil jets and used full floating-type piston pins.

The cylinder head is made of aluminum alloy which gives it good cooling efficiency. The engine has dual overhead camshaft design with four valves per cylinder. The camshaft is driven by the single roller chain pitch 8 mm with the outer hydraulic tensioner and lubrication nozzle. To variable inlet valve timing, the 2ZZ-GE engine used a variable valve lift system operated on the inlet and exhaust valves.

At engine speeds above rpm, high-lift camshaft profiles are engaged and the cam lobes increased intake lift from 7. The intake valves have a Calculate the thickness of new adjusting valve lifter so valve clearance comes within specified values. Valve lifters are available in 41 sizes to range from 2.

The main difference between the 2ZZ and 1ZZ is as follows: the 2ZZ got a composite cylinder block, crankshaft with a decreased piston stoke 85 mm82 mm pistons and increased compression ratio up to It strongly differs from the VVT-i model: after 6, rpm valve lifting increases and reaches not more than For some markets there are models with a decreased capacity of not less than HP.

Apart from that, a new 2ZZ exhaust manifold is applied. Its throttle body diameter is 76 mm. An exhaust system, comparing with that of the 1ZZ, has diameter increased to 58 mm. Therefore, you will have to adjust the valves in eachkm. In addition to a naturally aspirated motor, supercharged models came into existence. The supercharged 2ZZ engines were mounted only in Corolla and Lotus models. Oil is enormously consumed. This is the most common trouble after runningmileskm.

To sort that out is as easy as ABC. You should do major repairs of the 2ZZ what ever unpleasant it might seem to be. Knocking noise in the engine. The problem is similar to that, which is typical of the 1ZZ. If any, you should buy a brand new timing chain and replace that of you own. It must have strained. If any rough idling, cleanse throttle body units and idle run valves. While doing that thing, you should check everything. Besides that, the VVTL-i system needs servicing each 30, miles 50, km of mileage.

Without doing so, the system may come to a halt and decrease in its capacity can occur after working at 6, rpm.

Having reached such a rate of running, you will probably face a need of complete overhaul. Otherwise, you must purchase a new 2ZZ engine. To assemble a good 2ZZ turbo can turn to be quite a costly and complicated thing.

You will have to replace the valves with lightweight ones, purchase Monkey Wrench Racing valve springs, enlarge the oil pan, Walbro lph fuel pump, and cc fuel injectors. For developing HP, you need to get Crower connecting rods, cc injectors, and increase boost pressure.

That also helps the automobile to remain fit for city operation. You are only to purchase them and fit the stock pistons with them. At 7 psi 0. Without taking into consideration the fact that the 2ZZ-GE engine is highly forced, there is some backlog left for tuning.

All you have to do is purchasing Monkey wrench racing camshafts fitted with springs, making a head porting, getting a DD Performance intake manifold, light valves, 90 mm hrottle body, exhaust manifold, direct-flow exhaust system and ECU Apexi Power FC. When all the aftermarket parts adjusted, your engine will develop about horsepower.Bore is 82 mm 3.

Compression ratio is Power output for this engine varies depending on the vehicle and tuning, with the Celica GT-S, Corolla T-Sport,[5][6] Lotus Elise and Lotus Exige offering kW hp but the American versions of the Corolla, Matrix, and Pontiac Vibe versions only developing hp[4] with all later years offering anywhere from hp in to hp in due to a recurved powerband.

The differing power figures from through are due to changes in dynamometer testing procedures. Due to noise regulations, Toyota recalled them for a flash of the PCM to up their output to classify them in the more lenient sports car noise category.

The addition of a non-intercooled supercharger to the Elise SC produces hp kW with a considerable weight saving. Unique to the ZZ family, the 2ZZ-GE utilizes a dual camshaft profile system the L in VVTL-i, known by enthusiasts as lift to produce the added power without an increase in displacement or forced induction. The 2ZZ-GE was the first production engine to combine cam-phasing variable valve timing with dual-profile variable valve timing in the American market.

The table below lists the specifications of the two camshaft profiles. This is similar in concept to Hondas i-VTEC, but the two systems are very different in design and execution.

These gearboxes were unique to this engine; since then, only a few Toyota engines have been paired with either a six-speed manual or a Tiptronic-style automatic and only one other engine, the 4GR-FSE, has received both. Toyota commissioned Yamaha to design the 2ZZ-GE based on Toyotas ZZ block and the engine is similar to a typical street bike engine, in that it utilizes a nearly square stroke ratio allowing for high-RPM operation and producing a power peak near the top of the RPM range.

The high-output cam profile is not activated until approximately 6, rpm and will not engage until the engine has reached at least 60 celsius fahrenheit. The lift engagement and the engine redline vary by application.

The first Japanese versions were rev limited to rpm with a peak of hp. Consequently, it is impossible to over-rev the engine with the throttle alone; a downshift from a higher gear must be involved. A typical over-rev can damage the oil pump, commonly disintegrating the lobe ring, resulting in damage similar to the picture at right.

The entire exterior design and chassis is the same as the American Corolla. Bore is Output is 95 hp 71 kW at rpm with 96 ftlb Nm of torque at rpm. The Corolla Compressor and Lotus Exige S add a supercharger with intercooler to achieve hp kWwhile the Exige Rs supercharger increases output to hp kW. Toyota fixed the problem in late with a redesigned bolt that was installed on later engines. Mavis Sakihara.The Lotus Elise is a favorite sports car throughout the world due to its low weight, excellent handling, and effortless performance.

With an innovative bonded aluminum chassis, uncompromised suspension design, minimal weight, and mid-engine placement, it's a thrilling and responsive car to drive. While the Elise chassis was designed for worldwide use, its 1. Rover's K engine was a clean sheet of paper design with some innovative features such as through bolting of the bottom and top ends through the block and lightweight construction.

In later Elise models it made, and horsepower, with the main improvements coming through increasingly sophisticated valve control which yielded better breathing. While the Rover K engine had some innovative features and was relatively light, it was never designed to meet U. The K engine was a relatively new design in when Lotus proposed its use in the original Elise. But by the time Lotus decided to bring Elise to the U.

With the parts supply for Lotus' only U. In addition to keeping the dealer network alive, supplying Elises to a previously untapped U. Long-time Lotus development engineer and driver Roger Becker flew to Japan with the idea of sourcing Toyota's new, 1.

While his courtship gestures to the giant manufacturer were initially rejected, Becker persisted and succeeded in gaining a contract for the engines. It may have helped that Lotus and Toyota have a long history together, including Toyota purchasing engineering services from and indeed a minor ownership stake in Lotus during the s.

Being in wide use throughout the Toyota world means these engines have broad parts and service support, thus forming a good basis for the new, worldwide Lotus Elise model. Different bore and stroke measurements and valvetrains mean the two engines end up with different blocks, heads, pistons, valves, cams, rods, cranks, and so on.

They are truly different engines with little in common other than a similar displacement and a few general dimensions. This is the most recent in a series of Toyota performance engines created by Yamaha. As with the earlier Yamaha-designed Toyota 4A-GE which is the basis of Formula Atlantic racing engines, the 'G' designation of the 2ZZ-GE indicates a 50 degree included valve angle, which is a geometry selected for better breathing and higher performance than the flatter combustion chamber designs which promote lower emissions at the expense of power.

The 2ZZ-GE is Toyota's first all-aluminum engine, meaning it uses aluminum for both its block and head. This material and a high degree of engineering for weight reduction makes the 2ZZ-GE one of the highest performing engines available in its displacement class when power-to-weight ratio of the engine itself is considered.

This light and powerful engine is therefore ideally suited to the light Elise sportster. However Lotus has retuned the 2ZZ-GE for use in Elise, smoothing out the torque dip at the rpm cam changeover point and strengthening the torque in the other rpm ranges.

In addition to the improved torque Lotus brought the peak horsepower back up to in their U. Toyota has apparently expressed interest in the changes Lotus made to broaden and even the torque and increase the power. Changes to the Lotus version of the engine are not purely electronic, however, as a new intake and exhaust are also fitted.

The exhaust is so fully optimized that altering it reportedly results in a significant power loss. Aftermarket tuners and parts buyers beware!

However with the much lighter Elise to move, the gear ratios are put to more pleasant and effective use in the Elise. The significantly lesser vehicle weight together with the improved torque from Lotus' engine tuning makes this the best application of the 2ZZ-GE.

2ZZ and 1ZZ Service Manuals

Despite a pound weight gain due to air conditioning, electric window lifts, dual oil coolers and the larger engine, the new edition of the Elise continues to offer outstanding performance. Kuah also mentions that the new engine is proving to be very clean. The increased power and torque of the new engine and still-light final weight allow the car to improve upon the power-to-weight ratio of the original Elise.Quick links.

I assume the valve will probably need replacing. I also plan on replacing the valve stem seals. Or should they be replaced together? I plan on addressing the bottom-end also. I would think you might as well replace them if you are going this far but I may be wrong. I read here that you can reuse the old studs if they are still within spec after being stretched their first time, but I don't want any problems. I'll upload some pictures as I get into it with possibly more n00b questions.

Don't throw too much money in an old car sorry, it is. Look for a cheap engine from a junkyard, most come with a warranty. If that doesn't work, just replace what is necessary - the broken stuff. If it didn't burn oil, don't touch the pistons, etc. The seals should be fine with 50K on them, same goes for the bearings - but check them of course. Not that it 's the dreadful banging sound, but a remote possibility that it was the other higher pitched noise.

Knocking like that, and the fact that the spark plug was impacted would make me suspect you lost a rod bearing, the piston is travelling to far up. Was the video before or after you found the spark plug damaged? Seemed to idle ok.

So i assum the plug was impacted either while coasting down or when I hit 8k rpm. I'll start disassembling tonight if i'm not too tired from work and get some pics uploaded including of the plug. Still need my questions answered cuz i can't find any definitive answers in my searching the interwebz.

What could've caused this? Spun bearing? Also not sure if its normal for the 2ZZ's pistons to come slightly above the block deck but thats how mine is. Matrix ready for engine extraction. Came out remarkebly easy.This DIY is more advice to those who have experienced lift failing, the symptoms, the causes and the cure! This is far from comprehensive but should find the fault in most cases.

These engines very rarely go wrong so I doubt many people will need to read this. The target audience for this guide is an average DIY mechanic. Disclaimer: I can not be held accountable for any damage caused to your car by following this guide and is intended for information purposes only! So how does the high lift cam profile come into play? Well the rocker shafts are very important here because they are the oil lines that allow lift to operate.

Under low speed operating conditions the rocker shafts are at low pressure. When the ECU receives the right inputs more on this laterit sends a signal to the lift OCV oil control valve which operates causing a rapid increase in oil pressure in the rocker shafts.

This forces a plunger in the rocker, commonly known as a lift pin, under the high lift follower locking it in place.

This causes the valves to now be operated by the high lift cam lobe and Hey presto, Lift just kicked in y0! Oil flows into this hole from the shaft. Lift pin at low speed low rocker shaft pressure. Note the bottom of thelift follower can be seen here. In lift you can see that the lift pin has gone under the bottom of the high cam follower locking it in place.

The result:. As measured from the crank sensor. Obviously if any of these sensors go wrong or the transmission of their signal is impaired split wire ect then there will be no lift. On the other hand if you have a problem with lift and you have an unchecked CEL then get it checked!

It will point you to your fault much easier than all this. The next sentence is VERY important, if your car is anything other than smooth in lift ie. Jerky, lumpy or a dip in power during lift I personally would not use lift again or even the car completely until your sure it is fixed or checked out fully. If the screen was dirty oil flow will have been reduced having an effect on oil pressure. This in effect will stop the lift pins from locking the high lift follower in place.

Once they are clean, give it a try! There is a quick test you can do to check your OCV is working. Take the connector off with the ignition off!!! If you have had no luck here then it might be a good idea at this point to clean the lift oil lines using an appropriate pipe cleaning tool.
