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.

    • @joshuaho96 Hmm considering the drama you've seen/experienced, have you looked into getting a built complete long motor shipped from Australia?  Considering the AUD is basically monopoly money when compared to the USD, at a glance this seems like a good option?
    • Bloody Skylines, they put you through the bloody wringer! Stick at it! Stunning drag strip BTW! Where is it? Can see part of the name on the slip and probably should just Google it!
    • I mean the other day I had to walk someone through diagnosing why their timing belt was walking off the cam gears. At least one of the issues was a bent tensioner stud. Local mechanics have found runout on the CAS mechanism causing weird failures. I'm also no saint here I've documented some of the things I've had to learn the hard way. Something I discovered recently is that my CA emissions catalytic converters weren't even welded correctly to align the downpipe to the main cat and they tossed the support bracket that goes from the transfer case to the downpipe to support everything there. I spend a lot of time chasing down these decidedly unsexy problems and the net effect is it feels like I never actually get to the original objective (flex fuel, VCAM, oil control, cooling, etc).
    • At times with how you make everything sound, all I imagine Americans doing when they see a gtr is standing there looking at it and bashing it with a gun like how a caveman would with a club and hoping it fixes itself 
    • I think this is just a product of how the US market works for this stuff. Shops are expensive and there's no real way of knowing what kind of results you're going to get, people don't really have the institutional knowledge. I have heard too much at this point to really put faith in anybody "full service" except maybe DSport and they aren't really a full service kind of shop. If you go to the right place I have no doubt they'll get it right for you. Some locals have set it up right but the cost really is nuts and even now they're still fighting issues. And you know I'm a crazy person who thinks things like twin scroll, relatively short low-mount cast headers, PCV recirc to intake, recirculating BOV, right-sized for ~400 whp, MAF load, validating all of that to a standard comparable to OEM test programs, etc are relevant. For what it's worth, multiple local owners at this point have been stuck in a perpetual cycle of blowing a motor -> getting someone to rebuild it -> some missed detail causes the bearings to wipe and spin just outside of break-in mileage or drop valves or some other catastrophe -> cycle repeats. I usually only find out about this because I'm perpetually helping random friends with diagnosing car troubles, Skyline or otherwise. The single turbo stuff if I'm honest is mostly secondary, it just doesn't seem to achieve the numbers in the ~2000-3000 rpm region that I would expect given the results I've seen here or in Motive's videos. I don't really know what we're missing here in the US to be causing this. Lots of people like to emphasize the necessity of finishing the project first and foremost, but I'm not made of money and I can't afford to be trashing a 15k+ USD engine build with any regularity. Or spending my relatively limited garage time these days unable to triangulate problems because too much was changed all at once. Also, even if it isn't a catastrophic failure I would consider spending the cost of single turbo conversion with nothing to show for it to be pretty bad.
