its pretty much hard to say really..esp. with import cars...for sure most import had the odometer clocked back...when i purchased my r33 it was fitted with a GTR dash with has 40K on it...but the original dash has 85K on it and the car was imported on 2002..i've put an extra 5K on it since i got it,.now lets say my car has done 100K ( originaly ) well.. i have to say..it still is running smoothly for a fairly moded one.

just really depends on how you drive it and look after it...crash it and go R.I.P.

i'd say 35cm for a piace of string.

My r32 gtst made it to about a genuine 180k (based on a service sticker i found having 60k more than the odometer when i bought the car). Swapped the engine out as it was getting tired and blowing a bit of oil into the intake.

The last 60k were done with better than 160rwkw and the last 20k with 175rwkw.

Stripped the motor today and found everything was in pretty good condition considering, with a fair bit of blowbye obvious on the sides of the pistons and a bit of excessive wear on a couple of the big end bearings and some minor scoring on one of the main bearings. Other than that the bores still had obvious hone marks and there were no busted ring lands, damaged rings or anything like that.

and a piece of string is definately 30cm

Not necessarily... The faster you go, the shorter the piece of string gets :D So someone driving a highly modded R34 GTR might observe the same piece of string o be shorter than someone driving a stock R33 GTS-t for example...

All the nerds out there will understand what I'm saying.

How long is a piece of string?

easy and indisputable.....

double the string's centre to one side!!!! :wassup:

except for G-strings, more complex geometrical math is required here. :Oops:

not a RB - but my 1979 Toyota Celice has done 790,000 km's - same engine :rant:

i just service it every 15k and it's fine :rant:

umm.....so you get my point then?

Those 2 litres appear unbreakable, but 'truck' like!! :wassup:

I killed my RB26 with 62000k's on the clock, my RB25DE had a 114 on the clock when it was layed to rest and still went like a dream, i got it with 50 000k's on it and cained it everywhere, lots of drag and track days and it did about 30 000k's with a 75hp shot of gas running though it, in the few months leading up to the engine conversion i was trying to kill it but couldnt, its gonna go in a project car next year.

my r32 gtr has around 240,000kms on the motor, it's pretty stockish. It has had a modest power increase over factory however the improvements I have had done aim at reducing the revs and boost required to make the same power as factory. This still means my engine will now not last as long as if I had left it alone under the same servicing regime.

Basically the more power you have and use regularly the quicker you will need at least a bearing / compression ring etc. rebuild.

The concept that a worked engine (say race spec) is going to last as long as a stock engine with the power being utilised is for dreamers with no money. If you have no money then drugs, gambling and performance vehilces are a sure way to increase your risk of spiraling debt and depression. Have a nice day.

The RB series has been proven to bea very strong motor...

Its the heart of all skylines right back from the 31....

It has proven itself on the track/drags/rally and street use....

The life span is very hard to determine. As left standard and driven every day for an hour a day it should last longer than the panels (rust will take over before engine dies)... If boosted or NOS'ed, Drifted and draged every where then it aint gonna last that long....

Would you say a Big Block Chev is strong.... I would....

Then how come Top fuel dragsters re-build after every run.... Its cause their pushed....

That same motor reving at 2000rpm all day everyday would run for ever.....

It comes down to the build quality and treatment.... My 2c

      Welcome Thomas! Sounds like you've made some progress. Are you able to drive it and enjoy it a bit now ?

      New fix for low tyre pressure from bmw

      By The Bogan · Posted

      HUMVEE are fine in big open areas, but they are problematic on the street and tight areas As for reliability, some of the  US Army guys I have chatted with have said that when they were working they were fine, but, the do spend alot of time in workshops for multiple reasons, admittedly, they did get a hard time by the boys and girls who drove them I would definitely put them in the "buyer beware" category  They do look tough as nails though

      Just don't use ChatGPT or any other artificial stupidity for the equivalent of googling. Their demonstrated inability to discriminate reality from hallucination should be enough to make them totally untrusted. LLMs don't know anything and cannot think to even the smallest extent. They are just predictors of the next word, and that should never be confused with capability.

      Another little story of weird shit happening

      By GTSBoy · Posted

      I think, given the usage model described in the OP, I'd never ever experience the wonders of the 400kW upgrade. What I really need is boost from 2000rpm and probably no more than 260-270rwkW. But I suspect that the highflow is not actually the turbo for that purpose, so I may in fact need to get a G25 or 30 or something right sized and very spooly. We shall see after it is tuned. I've had to back the boost and boost ramp off to stop the thing from pinging since the highflow went on, so I've been almost living the NA life for 9 months now! Injectors are recently in hand. AFM is in hand. Dyno is fixed. Just need to clear a queue of f**king Supras out of the way (and probably fit my new gearbox). So....some time this year? Lol.

      braided lines for the turbos

      By GTSBoy · Posted

      For what I gather is a Sunday/summer car....braided is fine. You're not going to be left without a vehicle and you have plenty of time for inspection/maintenance. Oof. I wouldn't use them that way. They can probably handle the temperature** but the internal corrugations means that their flow characteristics are a bit shit. Lots of extra friction and pressure loss. Makes them flow like the next pipe size down. ** They are stainless, and the stainless can usually be at least something like 304L, which is pretty good at higher temperatures (unlike 316L, which I would use for a wrt/corrosive environment, but not a particularly hot environment). But the welding needs to be top notch. And even then, because you usually need at least one cone-seat end on them (because you can twist the hose and do up both ends at the same time unless one of them is a union) they can be prone to coming loose with heat cycles.
