So, how much abuse can a 2ZZ take?

[QUIKAG]

I was following around a bunch of sport bikes last night with one of my roommates in my Vibe GT filming my brother on his '02 Yamaha R1 and a bunch of other guys. Anyway, I had the revs above 5000rpm for probably 15-20minutes. I needed to stay close to the powerband so when the bikes took off, I could try and keep them in eye sight. I hit 8300rpm over 50 times too winding it out prior to grabbing the next gear.

So, any idea on how much abuse a 2ZZ can take before letting go? I'm sure it's a lot!

ANSWER = Toyota

Just don't mis-shift or repeat last night on a regular basis and you should see AT LEAST 150k outa ur ride.

BTW, what the hell you doin tryin to catch sportbikes in a VibeGT?!:chuckles: (hehe, jk) At least you tried!

EDIT: Maybe you could post a pic of your Vette?;)

Here's a pic of the C5 at an autocross. The Vibe GT actually did okay, they would accelerate on their bikes for a little bit and slow back down. A lot of the guys were doing wheelies and whatnot. I would have taken the Vette, but I need to replace the rear brake pads as they're squeaking pretty bad. The pads should be on my doorstep in a day or two.

The engine can take more abuse than the transmission can.

[QUIKAG]

What's the deal with the transmission? Also, any more feedback or real world examples of the type of abuse the motor can take?

[fox2000gt-s]

The motor will definitly out live the tranny. To me, it seems like the valves are a little weaker than they should be. If you really get on the gas very often, after awhile you'll probably start to hear some valve flutter. Not that they'll cause any major problems but, none the less, I believe they could have been strengthened some. As far as the rest of the motor goes you could probably beat the crap out of it and still get upwards of a 100k. Just be sure of which gear you're going into.

[QUIKAG]

Thanks, fox! So, I guess there aren't any other people on this board that run their 2ZZ motors hard?!?!?! Real life stories?!?!

[WillyK]

I run my car very hard, fairly often. I've had no engine troubles but did have a transmission rebuilt and then replaced a year and a half later.

[BRAK]

I run my car VERY hard , very often! The engine is great, and can take MUCH abuse, hell it has won awards for being the best 1.8 to 2.0 engine!!!

[TRD Liquid Silver]

the engine will be fine as long as you don't mis-shift while your redlining a gear. toyota/yamaha has done tons of R&D work before this motor was released and it all depends on how mistake free you drive it.

the tranny will boil down to the owner as well..

Sometimes this can be a problem with the 2zz: http://www.newcelica.org/forums/showthread.php?postid=1133248#post1133248 [/B][/QUOTE]

Hmmm, probably up to 500 to 600 autocross runs on mine, add in another 20 passes at the drag strip and a day at a road course (150 miles, 10 mpg) and you can start to imagine how many hard launches, rev limiter hits, etc that my car has seen.

The only problem I've had is the belt tensioner.

56,000 miles and the tranny is good, the engine is good (and still quiet, NO valve issues)

If you want some real life stories, just do a search for miss shifts. There are ton's of miss shift stories where the driver is bouncing off the rev limiter when they miss shift into the next gear down, and they write into this site to ask if we think they could have damaged their car.

Not only does the car drive after the miss shift, they continue to race the car immedeately after the fact to "test" their engine to see if it seems damaged. To me, the fact that the car even drives at all after such massive miss shifts, and continues to survive abuse right after the miss shift, is a testatment to how tough the engine is.

we dont bounce the rev-limiter, that would hurt the car, the RPM's go much higher than the limiter, into the 9k-10k range, causing the pistons to hit the valves, sometimes breaking the valves off and totally ruining your engine, thats what happened to me.

[chameleon]

???

FL Honda Stompr, your GT revs up to 9 - 10 thousand rpm's before a fuel cut limits it? That's not normal, the rev limit on my GTS is around 8400 rpm!

[SilverBulletGTS]

I think he meant it COULD go that high before causing damage if the limiter weren't there?

[Sirk_2]

NOOO
What he is talking about is that he mis shifted and then the ecu probably register the engine hitting 9-10K+ RPMS
and YES, a GT can do that, as well as a GTS...almost ANY car can do that...99% of the engines that do that just can't handle it.

[NoRulzAt140 Mph]

yes i was in my freinds gt, which im trying to make him buy a computer so he can join nc.org, he went from 5th to 2nd at about 75, an dthe rpm's slammed past the rev limitier (gt) and were bouncing on the 8 k line, , the dealer said he reved it to 987 suttin (can they really tell that?) anyways, all 16 valves, bent, as fl honda stmpr said. this was a few days ago.

[nudge1201]

In my GT-S it reved to 11500 rpm on a misshift and bent all my exhaust valves. I remember seeing a pic of a misshift at 100 mph into 2nd and the revs shoot up to 14-15k rpms and fused the pistions to the cylinderwall. and when you misshift your rev limiter does not stop your engine at the cut off because the momentum is what causes the over rev.

[chameleon]

Oh, I see what you are all saying.

When I said that people were "bouncing off the rev limiter when they miss shift" I didn't mean that the miss shift made them bounce off the rev limit. What I meant that the car was already maxed out in terms of safe engine RPM because they were bouncing off the fuel cut, then they miss shift which caused it to go even higher. I just wanted to illustrate that the engine RPM greatly surpassed safe levels. I guess I could have worded it better.

Autocrossed mine a month after I got her, and that was three years, three track events and countless auto-x's ago! I've calmed down on bouncing the rev limiter (first year auto-x'n) :) Blew one engine on a road track, tranny got replaced cause there was a loose piece of metal in there. Just past 60k and still going :)

Yeah, same thing happened to me. Small pieces broke off one of my gears and shredded up the rest of my tranny.

[QUIKAG]

So, barring a misshift, the motor should last a long time? I'm very careful as to what gear I"m going into, so I don't plan on having an overrev problem. I do bounce it off the 8350rpm rev limiter frequently, though!
