Hi all,

Just wanted to ask a quick question or two...i was wondering if any skyline owners with a RB20DET uses ever travels a fair distance (being at least over a 100km)...what is considered a safe speed to sit on engine wise?....i was just wondering because i sometimes drive my R32 over 240km distance like 4 times a year and i sit on a speed where the engine is revving around 4.5 - 5 revs...is that safe for RB engines?....comments would be apreciated

cheers

i drove from melb to queensland...

sat on 110-115 km/h for 2-3 hours straight for most of the time

sometimes up a hill with a full car (read: fridge, books, all my belongings plus me and my g/f) i would sit on full boost for 10secs while i climbed a hill

the good old rb20 didn't miss a beat! :)

what did you guys sit on?

I did a day trip 4 hours to, and 4 hours back.. sitting on 120km/ph most of the way

they are made for the track bro, they can handle heaps of shit b4 they get mad at ya! lol

120 was my slowest speed when i was on the freeway, and yeah same as the other guys, didnt miss a beat..

the only real time she used fule was when i was on boost! playing games with fords!! lol

Just did a re-calculation - more like 160 / 175, don't see a problem, used to do that and much more here in the other States in the '60s and 70s,for long distances, when it was legal, and those cars held together. RBs should do it easily.

yeah the car was doin around the 160+ mark at those revs. i was just a bit worried that sitting on this speed with a turbo engine being only a 2litre might not be good for the RB...however the engine did cope pretty well and at sometimes i would get carried away and hit 180km/h.

I drove my rb25 100klm each way return for 9 months in the NT, sitting just below the rev limiter at 190 for 1/2 hour each time. Also drove the car the 4500klm to get there....no problems except finding 98 octane :)

Cut wire 52 on the computer. Should be a green wire with a yellow trace or a yellow wire with a green trace....can't recall, it's been ages. Make sure you put a switch on it so you can exit from Hicas diag mode when you need to.

just a warning...

when i tried this wire 53 cut, i had issues with stalling when cold at low rpm

why? don't know...

problem went away when i re-connected the wire!

Hi, I once did a trip where I sat on 140 kms an hour for 4 hours solid - just cruising with no excessive acceleration and achieved 10kms a litre, not bad for an rb20det!

Like most cars it can handle high revs if the cooling system is in good nick, my car has been on several track excursions where it gets a 'good' workout over a 10 min period then a 30-40 min cooldown and the temp gauge has never moved from the normal position it sits on and has always idled perfectly after those runs.

:werd: i was doin between 160 and 180 for a good 30 mins with revs around 4500 rpm on the way to wollongong from liverpool , heaps of hills and the way down as like :headspin:

    • That idea has crossed my mind, I do a 5km walk everyday, this does take me past some bushland......I think you may be onto something 😉  That, plus 1 rock on every bin night might do the trick, it may take a year, but it could save me a couple of grand The only issue is the big 'Boonies", I have a few that weigh around 30-40kg, maybe they should be the first to go into the raised garden bed,  and then let the next owner deal with them....my daughter gets the joint when I kick the bucket, mums the word mate......LOL Noice......
    • Wow. Did you call the car a Nissan Skyline?
    • You're retired Mark, on bin night, go for a walk, kind of like you're doing the beep test. Put one rock in the first neighbours, come back, get another rock, go to the second neighbours, repeat over many weeks. All rocks eventually gone...
    • No chop chop of anything mate, it is what it is, plus, I don't want any air that isn't either going through the cooling stack or intake getting into the engine compartment increasing under bonnet pressure  Yeah, the Mazda Speed aftermarket intake above is less than ideal for multiple reasons, the requirement to remove the bumper every time you need to service the filter, and also smaller in diameter than the NC1 OEM one Weirdly, Mazda Speed is part of the Mazda motorsport division, "form over function" and $$$$$ for Mazda from unsuspecting punters I suspect  After some googling about them it seems they added no power, but do increase some induction noise Meh In other news, the electricians have been busy today at the house, and are back tomorrow finishing up all the security stuff and exterior lighting, they also added some lighting on the garage ceiling, which will come in handy when working in the garage when it's not freezing out there My Birdies raised garden bed also arrived today as well, which I'll put together and place tomorrow, it's a big tall Bessie, 74cm high, 92cm wide and 214cm long, this will come in handy as I am starting to get "stockpiles" of good soils from doing landscaping, some of the clean rock, namely the river stone, will go into the bottom of the bed for drainage, as well as the old Apricot tree that was out the back,  and when it's full, I'll grab another one, I will be growing enough veggies to keep me both busy as well as supplementing the shopping list I'm also awaiting another quote for a new Colourbond front fence, as the "1980 style cemented in rock edging" that was there and "fashionable at the time" looked arse, and my god, the amount of cement used to fix the rock was insane, it took 1.5 days for me to break out 12 meters of the stuff by hand, trim the bushes back to the fence line and dump it out the back of the joint to deal with at a later date,I will soon need a skip bin to tip it all Unfortunately they did alot of the cemented in rock around the joint, which I hate, so a few pallets of retaining wall blocks for around the front and back where the cemented in rock is will be required to bring it up to a standard, and look, that I will be happy with 12 meters worth of rock and cement Finished smashing the fence line and ready for a fence to be installed, yes, the lawns need some TLC and thickness, the previous owner trimmed the grass to the roots 😢, the TLC I can provide, and nature over time will do the rest And there's probably about another 40 meters worth of this landscaping abomination left to do around the front and back gardens, I'm guessing maybe 3 or 4 tons worth, tip fees for this will be a killer Meh, all in all I'm having fun and keeping busy, plus, it's good PT
