Toyota 1.8-litre 2ZZ-GT VVTL-I engine

[Tyoneal]

To All:

I don't know if it has been looked at or not, but this engine out of the late Celica GT's is also the Engine used in the lower end Lotus Elise Models. There are tons of parts and support, Turbo kits, and the engines and transmission are in the $2700-$3500 price range for everything. They are all aluminum DOHC 4 Bangers that rev to 8200 rpm.

The Lotus Elise weighs about 2000 pounds and the people who love to track their cars love these Engines. They are also dependable.

I would encourage the Owners of the SL-R Car kits to look at these as a possible candidate for this car.

Here are a couple of Links that I think will support this idea:

Anyway, just a thought.

Oh craps, I stuffed up, I was thinking of the 3S-GTE which is the Front WD turbo engine.....

Sorry Folks, I listed the wrong engine but 3T GTE and 3S GTE sound quite similar! What happens when you check the net 5 minutes before you pop off to work!

Sorry again - compare this one.

http://en.wikipedia.org/wiki/Toyota_3S-GTE_engine

Also rememebr that the 2ZZ GE Toy/Lotus motor is built not just for performance but also to meet many more regulations than the 3S GTE had to.

Yeah, don't waste your time when you can get Toyota's tuffest engine cheap and in spades .......

The 3T GTE...

http://en.wikipedia.org/wiki/Toyota_T_engine#3T-GTE

THE 4 cylinder turbo choice in my mind, 300hp without touching the internals and Front WD gearbox for them - research the net on them.
=======================================
I Guess, I'm not following you. (This is from Wiki)

3T-GTE

The 3TGTE is the most performance orientated version of the 3T engine. It features a twin-spark (two spark plugs per cylinder) design, is mated to a W55 5speed transmission, and is turbocharged with a Toyota CT-20 Turbo to generate 160 hp (119 kW) at 6000 RPM and 152 ft·lbf (206 N·m) at 4800 RPM.
Applications:
Toyota Celica A40 and A60 series
Toyota Carina A60 series
Toyota Corona T140 series
================================
The 2ZZ-GE (These have 30 more hp N/A, than the 3t does with a Turbo) With VVT, and being a Standard Engine in the Lotus, I have no idea how the 3T can be preferable to the 2ZZ-GE. Plus this is current Technology and is very well supported by the Racing Crowd.

Read Below and Tell me why this would not be preferable.

The 2ZZ-GE is a 1.8 L (1796 cc or 109.6 in³) version built in Japan. Bore is 82 mm (3.23") and the stroke is 85 mm (3.35"). It uses MFI fuel injection, has VVTL-i, and features forged steel connecting rods. Compression ratio is 11.5:1, necessitating "premium" gasoline (91 octane or above in the (R+M)/2 scale used in North America[4]). Power output for this engine varies depending on the vehicle and tuning, with the Toyota Celica, Toyota Corolla T-Sport [5] [6], Lotus Elise and Lotus Exige offering 141 kW (189 hp) but the American versions of the 2003 Toyota Corolla, Toyota Matrix, and Pontiac Vibe versions only developing 180 hp[4] with all later years offering anywhere from 173 hp in 2004 to 164 hp in 2006 due to a recurved powerband. The differing power numbers from 2004 through 2006 are due to changes in dynamometer testing procedures. The Australian variant Corolla Sportivo is 141 kW@7600 and 181N·m Torque 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 to achieve 225 hp (168 kW), while the Exige 240R's supercharger increases output to 240 hp (179 kW).

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 table below lists the specifications of the camshafts. This is similar in concept to Honda's i-VTEC, but the two systems are very different in design and execution.

Intake Exhaust
Duration Valve lift Duration Valve lift
Low Cam 228° 7.6mm 228° 7.6mm
High Cam 292° 11.2mm 276° 10.0mm
Excluding the 2003 MR2, the engine is also the only model in the ZZ engine family to use a 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).

Toyota commissioned Yamaha to design the 2ZZ-GE and it shares several similarities with street bike engines, the most notable being the relatively high RPM design. The high-output cam profile is not activated until approximately 6,200 rpm (the exact point of engagement is different depending on the vehicle, year, and PCM involved) and will not engage until the engine is sufficiently warmed up. The Toyota PCM electronically limits RPM to about 8200 RPM (or 8400 RPM in some earlier cars) via fuel and/or spark cut. Consequently, it's 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. Unfortunately, starving this particular design of oil is almost always fatal to the engine, even when caught quickly.

The engine will easily run at speeds of around 4,000 rpm for extended periods of time and is designed to periodically run at the 8,400 RPM redline without issue. For the first few years of production, the engines were notorious for failing "lift bolts". This didn't damage the engine, but would hamper performance, as the high output cam profile was unable to properly engage. Toyota fixed the problem in late 2002 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.

Also, 2004 and newer Matrix and Corolla XRS' were sold with smog pumps and have an extra hole in the engine block and header where the "air" is extracted for induction into the intake. It is of note that all 2ZZ-GE heads from 03/03 to current carry this modification even if the vehicles does not have the air injection system.

Applications:

Toyota Celica SS-II (Japan, 190 PS)
Toyota Celica GT-S (USA, 180 hp)
Toyota Celica 190/T-Sport (UK, 189 hp)
Toyota Corolla Sportivo (Australia, 189 hp (141 kW)/180 Nm)
Toyota Corolla TS (Europe, 192 PS)
Toyota Corolla Compressor (Europe, 225 PS)
Toyota Corolla XRS (USA, 164/170 hp)
Toyota Corolla Fielder Z Aero Tourer (Japan, 190 PS)
Toyota Corolla Runx Z Aero Tourer (Japan, 190 PS)
Toyota Matrix XRS (USA, 164-180 hp[4])
Pontiac Vibe GT (USA, 164-180 hp)
Lotus Elise (North America/UK, 190 hp)[7]
Lotus Exige (US/UK, 190 hp[8] & 243 hp [supercharged][9])
=========================================
I look forward to hearing from you. I've really been trying to find the best performing, best technology out there within the Toyota Line, and all arrows pointed here.

Please teach me where I am wrong. It wouldn't make sense to me for the new Lotus to be running these engines if the older technology and output of the 3t's were preferable.

Not trying to be a smart ass or nothing, just trying to see and understand what I have missed.

Sorry Mate, look at my first post again then you may want to adjust/delete your post as well.

Ah-Ha!

That makes a a big difference. I got to spend some time in the seat of a boosted MR2.

I had the best time. Can't say I left a lot of rubber on the back tires, however, to have the engine behind you at screaming at high RPM's and the Sharp handling around corners, it was pure heaven.

I am really hoping the SL-R will bring the same thing X 10.

Take care,

I know its an old post but might be new news. If you are going to use the 1zz or 2zz and using stock exhaust manifolds make sure you empty the pre cats!!! They are a problem on these engines. If not taken out they can cause engine failer. Check out the spyderchat forum here at www.spyderchat.com They have got as high as 300 hp out of the 2zz engines and good sorce for parts i.e. turbos and superchargers. Just to let you all know lol.
