Sounds like you are getting ripped with the machining costs.

Injectors and water/meth. e85 is too much dicking around for my liking.

Yep, going to a different servo is sooo difficult. :P

This thread is now delivering f**k yea Can we have a dyno graph with a single, twins and a third axis for bench press weigh for comparison

Twins on a RB will always be shit, all of a sudden the Muricans and Canadians are experts with RBs.

Look guys, I'm the guy who had the white 34 with 2863's in -5 housings, it made 489kwatw but at 33psi. It was a mental track car, I actually never got a proper time with that power figure on new tyres

Running a high end GTR on 98 is playing with fire IMO (no Pun intended), it feels like filling your car with a tank full of hand grenades.
You get a good tune, the AFR's and timing don't have much head room, you get a servo that dodgy's up the 98 with diluted 95 or 92 in it, which happens more than people realise.
You add in a hot day after you had it tuned in Winter, your at the track with water temps up, ambient air is up with a lower octane fuel than you thought you filled up on because of some scamming servo trying to rip people off and boom, it can be a recipe for disaster and it happens more than people realise.
An E85 setup for a few grand is one of the cheapest insurance policies you can have for longevity for your engine, let alone the performance increase.
You can't tune high boost levels over a max 24-25psi with 98, and between 24-30psi in my experience is where the GTX 2863's start to really show their abilities. -5's wouldn't really do much after 25psi anyway so it didn't matter so much.
Regardless of mods to any performance car, E85 is worth every day of the week.
I didn't make bugger all more power with my -5's when I tuned it on E85, but I was confdent I could race it at the track as hard as I want without a worry in the world.

When I was on 98 I would hear a knock here and there come through on bad batches of fuel with the check engine light coming through from the Haltech ECU, and with the inconsistency with the 98, I don't think it's worth it.
United are rolling out servos everywhere now with E92 and there should be no excuse now for saying ethanol is not easily available. Check the United website for Ethanol servos, they are popping up everywhere now.
When I sold my 34GTR recently it was driven from Brissy to Sydney easily between E85 servos. The other option for all those with a Haltech Platnum pro or the like, is you can use the sensor upgrade, it works a treat.
Drum E85 is a total waste of time and money, it is designed for a regulated racing series with consistency.
You can quite easily tune a car with a few HP less for head room and run the bowser stuff no problems at all. Buy a cheap Ethanol test kit, carry a 5L drum in the car with you, fill it, use the test kit for content level and you're safer than 98ron everyday of the week. I tried drum E85, never again, it is too much dicking around.

I took my car back got it tuned on Caltex E70-85 and lost like 15hp, so it was a no brainer for me, $1.14/litre for pump stuff, or $2.50-$3.00/litre for the drum for 15hp...........no thanks the bowser was just fine :)
Sorry about the big ramble again guys, I do get a bit carried away.

Very well said :)

I looked at United servo list in Sydney a few weeks ago and unfortunately it is still limited here.

Caltex eflex however is more readily available.

Already have the water/meth kit from the previous zed, so I might as well use it.

Even if United placed a servo at the end of his street, he still wouldn't use ethanol, because the bogans up the road told him it was bad news. You just can't help some people Simon.

Agreed, well said.

I noticed there are plenty of United servos selling e85 that arent listed too.

well all I got out of that is 'tune you're car on E85 and she won't go bang!'

Now that's been said I think I'm gonna take it to my tuner like ASAP.

I has Haltech platinum pro so looks like that ethanol sensor is gonna be coming my way :)

Hahahahah, thanks guys, " well all I got out of that is 'tune you're car on E85 and she won't go bang!"..........lol. The platinum pro is a good ECU and if you can source the Sensor from the States, it's just the GM version you'll save quite a few dollars I've been told, but I never tried the sensor because I was hooked on E85 all the time and I could never bring myself to even think about 98 ever again......lol.

It's a bit like tryres I suppose, once you have a set of 295 03G semi slicks, you are always on the hunt for the same level of grip :)

Anyway back to GTX 63's, the E85 will def allow the boost level increase so you can get your twins on song up around the 30psi mark. 33psi was max for me and was not yielding much more over 30-31psi. Different dump pipes, exhaust systems, cam profiles might get a little more boost top end, but probably yielding the efficiencies in the mid range would be my focus, especially not going to crazy with cams up at 272 degrees which I had. I should have gone back to a 260 really and keep a 11.0 lift. Big overlap cams are so over rated with turbo cars, I think it is a mentality that has come across from the world of Natural aspiration and drag racing cars with big automatic transmissions and stall converters, not forced induction.
I suppose a huge single for drag racing may benefit?

Hey Anthony, I only ran 1000cc ID injectors for the increased fuel flow with the E85 and was heaps for 478kw. I would probably try a different injector than the ID's, they haven't really had the best reputation from a lot of people and Ethanol for some reason, but the capacity at 1000cc is plenty. Have you got a good fuel system to deliver the increased fuel demand from ethanol? Also a dual entry fuel rail is essential too, in fact I reckon every GTR owner should have a dual entry rail, there is a reason the number 6 cylinder is the problem one :)
Man all theis talk about GTR's again makes me want my car back again, gee I would have liked to have kept on playing around with this.

yeah E85 seems the way to go especially with it being available so close to me.

My car has HKS 1,000cc injectors, HKS fuel rail, Tomei FPR, Walbro 450 ltr p/m so fuel system is not fancy mate.

Anyways, glad you getting edgy about having another GTR.

Anyway, back to the GTX talk ;)

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      By Duncan · Posted

      I thought I'd do a write up on an auto transmission fluid change for a the nissan 7 speed Automatic. At some stage the genius engineers decided that the fluid in the trans was "for the life of the transmission", (which seems kind of self supporting to me) and removed the dip stick and fill tube (funnily enough there is still a casting for it). Anyway, for this job you do need 2 specialist tools in addition to regular hand tools, jack and good chassis stands. You need a way to pump fluid up to the transmission; I got one of these but there are plenty of other options: https://www.ebay.com.au/itm/364584087070 Don't trust the generic listing though, it does not come with the required adapter for the Nissan 7 Speed. You need one of these, can't do the job without it: https://navarapart.com.au/product/genuine-nissan-patrol-y62-d23-np300-navara-re7-dipstick-fill-connector1 You need a heap of compatible transmission oil. Could be Nissan, could be anything else rated for Nissan Matic S. You need at least 10 litres, I had 15 to give it a better flush... Also, you need some biiig oil catch trays, at least one of these, or bigger if possible (volume was fine, size was very marginal): https://autobarn.com.au/ab/Autobarn-Category/Tools-%26-Garage/Specialty-Tools/Oil-Service/Garage-Tough-Oil-Drain-Pan-Black-16L---GT1068/p/TO03191 Finally, a measuring jug is very useful if your pump does not have volumes marked on it, I got a 6l one: https://www.repco.com.au/oils-fluids/fluid-accessories/measuring-jugs/penrite-measuring-jug-6l-pmj006/p/A5322648 Oh, and gloves.....this stuff is horrible (not as bad as diff oil, but getting there) ....First, jack up your car.....

      Duncan's V37.......race car?

      By Duncan · Posted

      So I mentioned the apprentice, @LachyK helped take the bonnet off. We just undid the nuts on the hinges and unclipped the gas struts, then pulled the bonnet back a little as the front was catching on the front bar.  I had a good look at everything today and have removed the rams, repaired/reset the hinges and bolted it back together like it never happened. I'll do a separate write up on the repair, and I also removed the poppers from the Fuga today too to save grief down the road.....as said above it is at least $5k to repair retail. I'm also happier about my ability to prepare a race car, and less happy about Nis-nault's engineering (I can hear @GTSBoy sAfrican Americaning) because the top hose of the radiator didn't slip off.......it snapped clean off. By practice I put the hose clamp hard up against the flare on a neck to make it least likely to ever move (thanks @Neil!). I guess that puts a little more pressure on the end of the pipe as it is further away from the rad, but still, that is pretty shit. I've put it back on for now as there was a fair bit of neck still there, but obviously there is no lip on the neck any more so I don't think I'll track it again until I have a new rad. Speaking of which....more research required. It looks like Koyo makes a standard size radiator in ally which I'll grab in the meantime, but I really want something thicker so might have to go custom in the medium term (ouch) Coolant still needs a refill and I have the pressure tester on it over night, but other than a wash down of the engine bay it seems alright. And @MBS206 noted something noisy on the front of the engine and I think I agree....time for a new accessory belt and tensioners I think.

      our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)

      R33 persistent issues. P/steering and lag/misfire

      By GTSBoy · Posted

      What are we supposed to be seeing in the photo of the steering angle sensor? The outer housing doesn't turn, right? All the action is on the inside. The real test here is whether or not your car has had the steering put back together by a butcher. When the steering is centred (and we're not caring about the wheel too much here, we're talking about the front wheels, parallel, facing front) then you should have an absolutely even number of turns from centre to left lock and centre to right lock. If there is any difference at all then perhaps the thing has been put back together wrongly, either the steering wheel put on one spline (or more!) off, and the alignment bodged to straighteb the wheel, or the opposite where something silly was done underneath and the wheel put back on crooked to compensate. Nut there isn't actually much evidence that you have such a problem anyway. It is something you can easily measure and test for to find out though. My money is still on the HICAS CU not driving the PS solenoid with the proper PWM signal required to lighten the load at lower speed. If it were me, I would be putting either a multimeter or oscilloscope onto the solenoid terminals and taking it for a drive, looking for the voltage to change. The PWM signal is 0v, 12V, 0V, 12v with ...obviously...modulated pulse width. You should see that as an average voltage somewhere between 0V and 12V, and it should vary with speed. An handheld oscilloscope would be the better tool for this, because they are definitely good enough but there's no telling if any cheap shit multimeter that people have lying around are good enough. You can also directly interfere with the solenoid. If you wire up a little voltage divider with variable resistor on it, and hook the PS solenoid direct to 12V through that, you can manually adjust the voltage to the solenoid and you should be able to make it go ligheter and heavier. If you cannot, then the problem is either the solenoid itself dead, or your description of the steering being "tight" (which I have just been assuming you mean "heavy") could be that you have a mechanical problem in the steering and there is heaps of resistance to movement.
