Im just curious how many people drive a rb26 powered vehicle as a daily to and from work? What mods do u have and how much difference has it cost u in fuel?

I have a rb26 powered r31 and was looking to grab a power fc, injectors and eventually n1 turbos. At the moment im getting around 350 to 400kms driving in traffic conditions and around 550km+ hwy driving. This is with a 60l fuel tank, ball bearing r34 turbos and full exhaust with 12psi.

Im willing to compromise a bit but not only to get 200l from a tank lol as i do a fair bit of driving. Interested in what others are getting from there daily rb26's

I split my daily duties between two cars but I get about that 450km/tank mark with 280KW. I actually get better fuel ecconemy in my R32 GT-R than I did in my GTS-T because the off boost drivability is a lot better. As we all know, you need to rev the nuts off an RB20 to make it move. Not that I had to do much in general driving, but I had to hit boost more often.

I've been dailying my R32 GT-R now, usually driving in traffic. Usually get 450-550 km per tank (60L) depending on how much boost it sees (not much) and more importantly how the AFMs feel lol. I got 650km once, but I did lots of highway kms and the AFMs were kind. Engine is standard, standard turbo, standard dumps and aftermarket everything after.

My goal is to get 10L/100km, which I believe is achievable with Nistune, new coilpacks and new AFMs.

You should be easily getting 550-600km to a tank if you take it easy. R31s are lighter and don't have 4WD.

When I had my R32 GTS-t, I was easily getting 600km per tank in traffic. Only mod was R34 turbo, everything else was standard including the exhaust. Damn I miss that car :( especially the sunroof lol.

Biggest factor is your right foot. If that's in check, then it'll be O2 sensors, spark, tune. Also if your car is an Aus-spec, make sure the rear calipers aren't dragging.

300KW and everything under the bonnet oversized pistons, 400Km per tank (If im lucky). It's been off the road for about a year though so im still not into the light foot stage...

I wouldn't use a 26 as a daily just because they are old. and they are cursed. I suppose the biggest difference you will see is from the turbos? if you have a turbo thats boosting in at like 2k (mine does) there isn't alot you can do about fuel.

I drive my 260rs everyday into melbourne cbd and out again all through peak hour. Quite stock atm, running 12psi, boost controller, turbo back exhaust and pod filters, SAFC.

I get 350kms in city traffic and 500km on highway driving. Being a wagon its heavier also. :-(

thats good to hear that with minor mods fuel economy still remains pretty decent. Have u all kept the standard cooling systems in place? one thing i find is the 26 feels horrible in the heat, keeps me in cruise mode though which in return keeps me out of trouble with the boys in blue so no complaints there. Only main problem i have had has been a few split coolant hoses over the past year, apart from that a 26 is a joy to drive daily

I daily my 34 GTR. With front pipes and exhaust I was averaging 320-350kms in inner west traffic every weekday. With 275 tyres, that makes a difference too I think.

Now with e85, haltech, 1000cc inj, pump, wideband I got 110kms to half a tank. With about 50% highway 50% thrash and traffic. Not real happy with that to be honest. I'll give it a couple of weeks to suss out what the average is. I may have underfilled the first tank of e85.

Not sure - didn't dyno it prior to putting the Haltech etc in.

Didn't have anything expect the front pipes and exhaust previously - it was boosting to 1.2bar by itself in 1st and 2nd and about 0.9bar in 3rd and 4th in cold weather.

    • There's plenty of OEM steering arms that are bolted on. Not in the same fashion/orientation as that one, to be sure, but still. Examples of what I'm thinking of would use holes like the ones that have the downward facing studs on the GTR uprights (down the bottom end, under the driveshaft opening, near the lower balljoint) and bolt a steering arm on using only 2 bolts that would be somewhat similarly in shear as these you're complainig about. I reckon old Holdens did that, and I've never seen a broken one of those.
    • Let's be honest, most of the people designing parts like the above, aren't engineers. Sometimes they come from disciplines that gives them more qualitative feel for design than quantitive, however, plenty of them have just picked up a license to Fusion and started making things. And that's the honest part about the majority of these guys making parts like that, they don't have huge R&D teams and heaps of time or experience working out the numbers on it. Shit, most smaller teams that do have real engineers still roll with "yeah, it should be okay, and does the job, let's make them and just see"...   The smaller guys like KiwiCNC, aren't the likes of Bosch etc with proper engineering procedures, and oversights, and sign off. As such, it's why they can produce a product to market a lot quicker, but it always comes back to, question it all.   I'm still not a fan of that bolt on piece. Why not just machine it all in one go? With the right design it's possible. The only reason I can see is if they want different heights/length for the tie rod to bolt to. And if they have the cncs themselves,they can easily offer that exact feature, and just machine it all in one go.

    • This is how I last did this when I had a master cylinder fail and introduce air. Bleed before first stage, go oh shit through first stage, bleed at end of first stage, go oh shit through second stage, bleed at end of second stage, go oh shit through third stage, bleed at end of third stage, go oh shit through fourth stage, bleed at lunch, go oh shit through fifth stage, bleed at end of fifth stage, go oh shit through sixth stage....you get the idea. It did come good in the end. My Topdon scan tool can bleed the HY51 and V37, but it doesn't have a consult connector and I don't have an R34 to check that on. I think finding a tool in an Australian workshop other than Nissan that can bleed an R34 will be like rocking horse poo. No way will a generic ODB tool do it.
    • Hmm. Perhaps not the same engineers. The OE Nissan engineers did not forsee a future with spacers pushing the tie rod force application further away from the steering arm and creating that torque. The failures are happening since the advent of those things, and some 30 years after they designed the uprights. So latent casting deficiencies, 30+ yrs of wear and tear, + unexpected usage could quite easily = unforeseen failure. Meanwhile, the engineers who are designing the billet CNC or fabricated uprights are also designing, for the same parts makers, the correction tie rod ends. And they are designing and building these with motorsport (or, at the very least, the meth addled antics of drifters) in mind. So I would hope (in fact, I would expect) that their design work included the offset of that steering force. Doesn't mean that it is not totally valid to ask the question of them, before committing $$.
