I have an R33 GTS-T Manual skyline.

I have just got a job that means I will drive about 120k return each day to work. It will be 95% highway driving at 100kph.

Now this is my first import. I have only owned falcons before which are built for the highway slog.

FYI, the car has been properly serviced. syn oil every 5000ks. new gearbox and diff oil, new plugs, timing belt done etc...

Now as you would all know the car sits at about 2600-2700 at 100kph. Is that too much to be doing 600ks every week? Am I going to wear it out really quickly if I do this sort of rpm all the time? or will it be fine if I keep the oil changes up?

What sort of lts per 100kph can a turbo skyline get if its in good mechanical condition when used on the freeway?

any thought on this would be great

Thanks!

why do people seem to think that skylines are some mythical beast that needs to be treated in some special way and can't be driven like a normal car? they are just a standard family car with a turbo attatched. it will be more than fine to do the highway run in. highway driving is generally better on cars than the stop/start of city driving.

as for fuel economy, you should see around 10L/100kms on the stock ecu.

thanks for the reply. I figured provided i service it the way I do it would be completely fine. I usually change the engine oil (synthetic oil + drift magnetic filter) every 5000kms. Do you think that given the light loads that are applied on highway cruiseing I could make it 7500kms without any harm? at 5000kms ill be changing oil every 2months!!

Now I just wish nissan put cruise control in them!

yeah 7500kms of highway driving would be fine. in city driving you can spend a lot of time just idling which is wear going on the engine but not on the clock

mate no offence, but you start pointless threads every few days it seems.

YES its a car it will be able to do it, its built to do that shit, if you didnt know that then maybe you should catch the bus.

Thats pretty unfair really. I don't start threads every couple of days about this sort of stuff. Nothing I ask isn't without some sought of grounding. This is a forum designed to allow people who are not experts in skylines, find out the information they need. If this offends you I'm sorry. This is the first skyline I have owned, everything before has been a low reving highway slug, I wanted to know how these engines/drivelines cope with that sought of driving as very few people use them for that. Once again I apologise for upsetting you, I'll stop flooding the forum and leave more space for people starting threads about 'what turbo will suit my rb25 best'.

sounds good :banana:

in all essence mate.. A car is a car.. Lots of people use them for highway driving.. especially R33.. they are everywhere.. As long as you service is regularly with the correct equipment then your car will be fine..

You do less wear and tear to the motor when you sit at a constant speed, i.e., highway driving where the engine sits at a constant rpm. You cause more engine wear & tear from city driving.

Didnt mean to offend you, or bring you down or anything man, my appologies :P

Won't be the most comfortable of trips but it will handle fine mechanically. I do wish the R33 had a longer 5th gear or even a 6th gear...the engine could easily do the job with 500rpm less at 100km/h. But these cars were meant to get off the line quickly and the compromise is fuel economy. It won't be fantastic, no turbo petrol car is at highway speed compared to n/a counterparts...but will be much better than city driving that's for sure.

when i'm on the freeway for long periods, i like to give the throttle a stab here and there, get into positive boost, or back off a bit, etc. just to keep the revs moving around.

dunno if it's any better for it, but sitting at a steady 3krpm for long periods just sounds unhealthy to me lol

the sitting at 3krpm isn't an issue. pretty much every 4 cylinder will sit at that sort of rpm at 100km/h.

as for being off boost, yeah that cuts the fuel down a bit, however you are at the sort of rpm that you will very quickly be into positive boost on hills or just speed up a bit, so you can very quickly start drinking the fuel if you aren't very smooth with your throttle application. just grab a multimeter and check your o2 sensor is working, otherwise your fuel economy will really suck.

Now this is my first import. I have only owned falcons before which are built for the highway slog.

If the rest of the thread wasn't sensible I would swear you are trolling. falcons built for the highway? yeah, maybe parking on the side of it after they overheated (seriously, 90% of the cars i see broken down at the top of a long hill are falcons).

10L/100km for the freeway, no problems. motor loves it.

i'd take a commodore or falcon for highway driving over a skyline any day of the week.

the only reason you'd see falcons on the side of the road comes down to the lack of maintenance by a lot of owners, not the actual cars. if skylines were treated like a lot of commodores and falcons are there'd be a hell of a lot more of them on the side of the road broken down than commodores and falcons.

    • Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.
    • @PranK can you elaborate further on the Colorlock Dye? The website has a lot of options. I'm sure you've done all the research. I have old genuine leather seats that I have bought various refurbing creams and such, but never a dye. Any info on how long it lasts? Does it wash out? Is it a hassle? What product do I actually need? Am I just buying this kit and following the steps the page advises or something else? https://www.colourlockaustralia.com.au/colourlock-leather-repair-kit-dye.html
    • These going to fit over the big brakes? I'd be reeeeeeeeaaaall hesitant to believe so.
    • The leather work properly stunned me. Again, I am thankful that the leather was in such good condition. I'm not sure what the indent is at the top of the passenger seat. Like somebody was sitting in it with a golf ball between their shoulders. The wheels are more grey than silver now and missing a lot of gloss.  Here's one with nice silver wheels.
    • It's amazing how well the works on the leather seats. Looks mint. Looking forward to see how you go with the wheels. They do suit the car! Gutter rash is easy to fix, but I'm curious about getting the colour done.
