High rev range healthy?

[Sporadic]

Hi All

I have had my toyota celica vvti 2002 for a 4 months now and was wondering if anyone had any tips as I have heard that it needs to be over 5000 revs for the power to kick in, but as an example, 3rd gear at 5000 is 60mph ish, bar it using up more petrol being in a lower gear, can it have a wear and tear on the engine? as it is old now and I want it to live for a few more years at least?

sorry for the n00b question but thanks for your replies

[Pericoloso]

I would expect in 3rd gear at 5000 rpm is considerably more than 60 mph.

Unless your clutch is slipping as per your other thread.

[Sporadic]

Thanks for your reply. I guess I need to look into a new clutch kit then. would you recommend any brands in particular?

5000rpm in third at 60mph sounds about the same as my 306, which is a six-speed also. Not sure on the ratios on the Celica, but can't be too dissimilar.

There is a red line for a reason.

If you are not going to use the revs, buy a turbo or V8

Is it a regular 140bhp Celica or the 190/t sport?

Hi Guys

It's the 190

It will be the 75 if you don't use the revs

Sure that's more likely to be marginally more wear and tear, but if the engine has good compression, doesn't use more oil than normal for the car and there is no blue smoke I've always thought that giving the engine, once warm, a good work out does it good.

Haha I just don't want it put the old fella under too much stress

As long as you're not bouncing off the limiter it won't do any damage. You might want to keep a close eye on your oil level though, that engine burns a bit if I remember correctly.

I'll give it a go. thanks

Nice one, I'll try sticking between 5-6 just so it's not too much stress

With respect, what did you buy a known high revving coupe for?

Whilst it’s good to take the revs up to the top every so often I wouldn’t sit at that rpm for a long time for example when cruising.

Totally agree with this. In day-to-day driving you'd rarely need to exceed 3000rpm. Only use the power at the top end when you want to (once the water and oil are up to operating temp of course).

I ran my 2l Mk2 Mondeo to ~170k before I sold it... I picked it up at 96k and it got to see >5k every day.

The only reason it wasn't seeing the red line every day is it just made noise over the last 1k with no appreciable additional acceleration so there was little point in it.

It ran just as sweetly when I got rid as when I bought it.

A Toyota OTOH? I'd expect it to reach 300k or so without any grief, just keep the oil changed and it'll be fine.

Agreed there is absolutely no point running at high revs when cruising along. You're just burning extra fuel for no benefit.

What wears an engine is "torque" not "revs".

Imagine you're riding a bicycle - which is harder, spinning the pedals quickly in too low a gear or standing up and heaving on the pedals in too high a gear? It's exactly the same inside an engine. Unless you over-rev the engine it will suffer no harm so long as you don't labour it too slowly, especially from a cold start.

By the way, over-rev is almost impossible in a modern car because there will be an electronic rev limiter. However, what can do real damage is "missing a gear". In other words, changing accidentally from 5th to 2nd in a manual car when you intended to select 4th. The engine will over-rev when you release the clutch and may suffer damage. Such incidents are typically logged in the ECU and official dealers may refuse to accept a trade-in for "Approved Used" if the engine has suffered over-rev incidents. I believe Porsche set the limit at 5 over-rev incidents.

I think it's been mentioned on here before, but the 190 VVTLI engine produces less power and torque on the first cam (before cam change at 6200rpm) than the lesser 140 engine does at the same rpm.

So rev it beyond 6200rpm or your driving the slowest Celica.
