Paul t  why does your clicky go to the microsoft site???

Er, dunno. Which clicky are we talking about, and how do I change it :D

Guess I must have put it in to test what happens.

Cheers

Ops!Sorry Paul T.

Please add up to the previous statement this one as well.

Both must be considered.

The 1ZZFE and 2ZZGE are Toyota’s latest 4 cylinder engines. Both are all –aluminum 1800cc 16-valve engines with variable cam timing, matching the current offerings of other manufacturers. This is Toyota’s first all aluminum 4 cylinder block. The 1ZZFE introduced in 1988, without variable cam timing- was updated with VVT, when the 2ZZFE debuted in 2000. The 2ZZGE- was further enhanced with a variable lift feature.

The variable cam timing feature addresses the problem associated with the old FE engines. (Please read the separate notes in the TECH Section.) Without VVT, the old engines seemed to run abruptly out of breathe- a function of their smooth power delivery that promised “more”- but hit a performance wall. The VVT 1ZZFE and VVTi 2ZZGE- now have the performance surge to satisfy the driver. (Of course people will still want more, which is why Toysport is in business.)

It is very interesting to note the difference between the two engines. The 1ZZFE and 2ZZGE are of the same displacement, but their bore and stroke are different. The 1ZZFE “izzy” with the FE head is the quick response, high torque model- has a longer stroke ratio, to further improve the torque characteristic. The 2ZZGE “duzzy” with the sports type GE head is the high RPM, higher HP unit- with a square bore / stroke ratio. This allows it to rev and deliver power in the higher RPM range.

The driving characteristic of both engines are dramatically evident. In the 2000 Celica, where both engines are offered- the GT with the 1ZZFE is easier and smoother to drive- more responsive. The GTS with the 2ZZGE starts of lazier, and need lots of pedal- but ultimately more HP. Which is a good contrast- drivers now know the trade-off between drivability and horsepower. A lot of people who tested the cars opted for the more responsive GT model, although they were initially looking for power. The power band characteristic of the two engines offer a good choice- chooses which is more important.

A recurring question- why did the MRS end with the 1ZZFE? Overall, the 1ZZFE was more compatible to the overall concept. The 2ZZGE would need more attention driving (to extract the power)- detracting from the fun aspect of cruising. For diehards- yes we can do the 2ZZGE conversion.

From Toyota’s early pioneering Twin Cams, to the succeeding multi-valve DOHC engines, to this new generation of variable cam timing and lift units…..Toyota continues to be the world’s largest Twin Cam manufacturer. As a review: Toyota Twin Cams have seen it all- 2, 4, and 5 valves; four, six, eight, twelve cylinders; normally aspirated, supercharged, turbo, and twin-turbo; gas, propane, and diesel. TVIS, non-TVIS, and individual throttle bodies. Been there, done that.

BUILDING THE ZZ ENGINES

The aluminum block is hefty and casted really clean. It will allow the engine to produce massive horsepower over stock. Dimensionally they are bigger than the 4AGE, the engine family it is superceding. Block strengthening is possible, by pinning the cylinders to stabilize the bores. The crank is a lightweight design and so are the rods. The crank and rods are casted really well, stress-relief and shot-peen- will produce parts that look forged.

The 2ZZGE has problems. Bent valves from missed shifts have been common. Sticking valve mechanism also cause unscheduled visits to the Toyota Dealers.

Toyota is addressing these problems currently. We have forged pistons in stock and .5mm os available with deeper valve reliefs and a .5 higher compression.

Dont I know it!

Hi Nick,

The statement is valid for 1999-2000 years.

In the meantime(what Toyota claims) they have sort out the issue!

If I remembered you have a same issue in the past isn't it?

[PaulT]

Thanks for the info, Mircea. It's very interesting to see the different strategies for the 1.8 engines with/without lift.

Regarding the Elise, you can see how Lotus changed the map from this chart. They have managed to give the lift a bit of a jump and also seem to have found some more (maybe +10%) mid-range torque. Probably that's causing the increased fuel consumption, although might be quite nice to have in the Corolla.

The thing about the Toyota production cars is that they must have reasonable fuel economy and low emissions, just sneaking under 200g/km C02 in UK, and most importantly high reliability. Lotus doesn't care so much about fuel efficiency and probably not so much about ultimate reliability either.

There seems to be a bit of a buzz of the Celica forum about a new generic

mod chip which should be available shortly. Hopefully that could also be used on the Corolla. Wish I could afford to try, writing your own engine maps would be a serious laugh!

Other than that, the best people have been able to do at the moment and still get an improvement is move the lift to 5800rpm. Seems you can also increase the top end to 8600+.

Time will tell whether anybody can stretch the band a bit lower.

Cheers

Paul.

2002 Corolla T-Sport Scraping Noice

After the car had only covered 20,000 did it only start to cause problems, the engine blew itself to bits needing the following to be replaced.

1, new camshaft

2, four new pistons

3, 16 new exhaust inlet valves

4, new clutch

After six week driving a Toyota Yaris I finally was given my T-Sport back, but with a very tappy engine and a clutch that didn’t feel very nice at all. As I only just got the vehicle back I decided to let everything bed in and see what it was like again after 500miles, unfortunately it didn’t even make 500miles before the new clutch collapsed not allowing me to change gear. Back the car went again for its third clutch, this was fast becoming a joke. After another 3 week off the road and back in the Yaris the Corolla was back in my possession, when I got it home I went to check the oil and to my complete disbelief the dealer had left off my plastic engine cover!

Over the last 2 month of ownership the car started to make this nasty scraping noise at low RPM under load this was the final straw for me hence the arrival of my Honda Civic Type-R which may I say is one of the finest cars I have ever driven!

Hi Paul T,

Thanks for the info.

2ZZGE -from my point of view is allready high tuned.

I hope that the new 2006 TS will come equiped with 2.l engine with higher

low-midle range torque and most important with a new higher tune and lighter chasis so that the ratios weight/power hit under 6kg/hp and more than

180 torque/t.

All the best,

Mircea

[Aphelion]

Hey what's this i hear about a 2006 T Sport, is this when they are going to soup the car up a bit?

Any one got any news??

By the way Nick did you ever find out what the casue of the scraping noise was??

Cheers

[eep2nw]

Sounds like Nick has got his entire engine replaced.... mine's just covered 20Kmiles as well as I'm getting those scraping noises... I hope it's not a fault with the engine....(haven't heard celica owners complaining yet)...

Hello everyone!

the graph posted here:

http://www.puresportscar.com/gallery/showp...&sort=1&cat=506

reminds me of the graphs that the cold air intake guys promise. maybe lotus didn't do that much to the ECU program but instead just optimized the intake?

PS I've been reading your forum for some time now. Thank's a lot for the info. I have also dacided to take a CTS, just having a final thought.

The only problem is that it'll be the first 3d Corolla in Russia! So im really afraid of service problems... I went to the deler and asked him to call the chief mechanic. I asked the mechanic about the 2zzge engine and he told me that it's the same as the 1zzge with a more advanced ECU!!! He said that the cyl. heads and everything are the same!!! But it seems that there's a garage which has sold three of four of these cars and im going to talk to them this weekend, maybe the situation there is better. the only good thing here is that RON98 petrol costs $0,5 per litre!

[ROSS KELLY]

Why get a type R when everybody and the granny has got one.

Get a cts and do it up and be different!

Ive got mine down to 6.4

[xoom]

Hi Guys,

I have noticed a few of you guys have gotten 0-60mph times from a track test.

When you guys get this done do you recieve a print out of a time slip ?

If you do would it be possible to get some of these scanned and put online ?

Cheers

[bzn]

The thing about CTR is that everyone knows what it is and what it can do. Everybody knows that Honda claims a 6.6 0-60, but nobody, exept the people that have a CTS knows what it can do! Read the CTR forums! They all think it's really gor a 8.4 0-60 sprint!

The guys that got beaten by one say it's turbocharged! And this is what hot hatch owners think! Who bout the gen public?

IMO, only cos of this factor the cts is superior, let alone the interior, running price etc.

[mircea]

Hi bzn,

For the same reason I got my TS instead of any other hot hatch!

Bealive me! To see their faces( BMW's,AUDI's, ETC owners) when Lift come into live

paid off all the money!

Just three in Moscow?Perfect!You have the exclusivity as well!

Just got a written slip this time, however, here is the actual clock! (And an action photo, exciting! :lol: )

Hi Paul

Thanks for that.

Just a question. Have you done any modifications to your car or is it all still standard ?

Cheers

No modifications, 100% uk factory spec., Jan 2003.

FYI. out of interest

Toyota Matrix XRS (US/Canada) bigger and heavier than the T-sport

Toyota's stats

0-60 mph, sec 7.8

1/4 mile, sec @ mph 15.7 @ 91.5

[exon16m]

i have a video of my cts 0-60 in under 8.4 (video of the dash) but dont know how to put it on here message me if you can help

[Blacksheep]

I've done 2 things to my T Sport which have greatly increased the mid range performance, 1 was fit a Blitz Air filter, the other which transformed the car was to fit a High Flow sports cat, I've lost a little power ?(5%ish) below 3000rpm but I would say the power above 3000 has gained anything from 10%-20% and has much more pull where it used to be a little flat at 4000-5500.

I must also mention however my car has only done 1800 miles so a bit is going to be the engine loosening up, but believe me when i had the cat done it transformed the car, i've also taken it to Toyota to check it still past the emission test and it flew it 0.00 on the display perfect.

The guys that fitted the cat for me told me the standard one really was a horrible little unit (or should I say big the one fitted is half the size) and I should notice a big improvement mid range, which is exactly what i have noticed, i haven't noticed any difference in fuel consumption except its actually getting a little better although again thats probably down to the engine etc loosening up...

[Black RunX]

I also believe that the CTS has a low 7sec 0-60 time because I have killed other cars that have been tetsed at 7.7 - 8 secs...
