ok guys i got my girlfriends sister and she thinks that the more you rev the car the better it is for it. becuase you should be working the engine?

ok she drives a lil honda civic.

most cars these days are not maid to be reving at 3000 rmp to 3500 rpm

now there is proberly nothing wrong with doing this

but doing this on every gear every day..

i see it as eventually not damaing the engine but wearing it out and the life of the einge will decreease..

no guys dont get me wrong we are talking about normal cars here

also applies to if you got a sports car eg skyline and rev the **** out of it every day your ganna tell me its ganna last as long as some one not reving it as much

Let me know what ya think fellas

Thanks =)

Cheers

I would think that every rev is doing you damage.

Every engine is made to rev.

My point, every time an engine runs it is wearing out. It is a simply case of friction. The faster an engine revs the hotter it runs the more friction that is created and the faster an engine will wear. You cant relly say that high revs are doing damage, thats what engines do, but it is wearing out quicker than if your didnt rev the engine hard.

Highly modified engines are designed to rev higher, they are designed to opperate more eficently at higher revs, but still the longevity of the motor is sacrificed. Look at F1 engines. One race and they need to be rebuilt.

Every rev is doing you dammage.

Simply, a motor that reves low or is not under much strain is going to last longer than an engine that is reved hard, eg. 250cc generator motor compared to a 250cc motor bike.

However, engines do need a good punt every now and then to circulate the oils and get rid of carbon and oil build up.

In other word I dont relly know what the hell im talking about but it sound good. You decide :)

I thik Eric is onto something. It depends on how you treat it, that means how you maintain it as well as how you drive it.

A bit of a squirt now and then on a well maintained car is not really going to hurt it.

Thrashing the crap out of it with the oil level below the end of the dipstick is not going to be a good thing.

Taxis and interstate trucks do huge mileages, and get driven pretty hard as well. The driver, often, is not the owner. But they do get regular service though, and last a very long time between rebuilds.

The reason taxi engines last so long is that they rarely cool down. Cold starts are the worst enemy of any engine, and is the time when most of the damage is done.

It doesn't hurt to rev an engine every now and then. I put a L20ET into my 240Z in 1989, and never had to touch it (bar a couple of dead welsh plugs) since. And it got plenty of canings in its lifetime. Its being lined up to be transplanted into a R30 hatch, and it will have a RB20DET turbo hanging off the side, not that restrictive POS it come out of the factory with.

      J50 clock date suddenly reset to January 1

      Well, I can recommend the partial AV system translation CD I ordered from Car Audio Workshop in NZ. Whilst it didn't address the date issue, it has conveniently translated on-screen menu items into English, and now allows the GPS-received time to be offset in hours rather than minutes, so I can display Eastern Australian time accurately ( and bump it by another hour when daylight savings starts ).

      Yuh, if it's 45°C outside, my car is driving in it.

      I'd be curious to hear more. Otherwise, have you driven a modern x-trail? I wonder how it compares. Here in Australia they are/were popular for rentals and fleet vehicles. I have been in some and my impression was they are bad. But, this may have been very different in the 2000s at a good trim level. Twenty years is plenty of time to make the model worse. I do very much agree with the 2 silver cars in the garage approach. But, not driving because it's too hot would not leave a lot of time in the year for many Australians. I don't think you need to worry too much unless the car has actual issues with overheating.

      Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.

      Thanks for that, hadn’t used my brain enough to think about that.
