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

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.

Jimboomba, between Bris and GC, but west'er haha

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

Edited by MagicMikeZ32

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 ;)

    • I'm looking for some real world experiences/feed back from anyone who has personally ran a EFR7670 with a 1.05 exhaust housing or a .83 I'm leaning towards the .83 because its a street car used mostly for spirited driving in the canyons roads. I"m not looking for big numbers on paper. I want a responsive powerband that will be very linear to 8000 rpm. I dont mind if power remains somewhat flat but dont want power to drop off on top. The turbo I've purchased is a 1.05, although the mounting flange T3 vs T4 and internal vs external waste gates are different on both housings, I not concern about swapping parts or making fabrication mods to get what I want. Based on some of the research I've done with chat gpt, the 1.05 housing seems to be the way to go with slightly more lag and future proofing for more mods but recommends .83 for best response/street car setup. AI doesn't have the same emotions as real people driving a GTR so I think you guys will be able to give me better feed back 😀   
    • Surely somebody has one in VIC. Have you asked at any shops?  Is this the yearly inspection or did you get a canary?
    • This is where I share pain with you, @Duncan. The move to change so many cooling system pieces to plastic is a killer! Plastic end tanks and a few plastic hose flanges on my car's fail after so little time.  Curious about the need for a bigger rad, is that just for long sessions in the summer or because the car generally needs more cooling?
    • So, that is it! It is a pretty expensive process with the ATF costing 50-100 per 5 litres, and a mechanic will probably charge plenty because they don't want to do it. Still, considering how dirty my fluid was at 120,000klm I think it would be worth doing more like every 80,000 to keep the trans happy, they are very expensive to replace. The job is not that hard if you have the specialist tools so you can save a bit of money and do it yourself!
    • OK, onto filling. So I don't really have any pics, but will describe the process as best I can. The USDM workshop manual also covers it from TM-285 onwards. First, make sure the drain plug (17mm) is snug. Not too tight yet because it is coming off again. Note it does have a copper washer that you could replace or anneal (heat up with a blow torch) to seal nicely. Remove the fill plug, which has an inhex (I think it was 6mm but didn't check). Then, screw in the fill fitting, making sure it has a suitable o-ring (mine came without but I think it is meant to be supplied). It is important that you only screw it in hand tight. I didn't get a good pic of it, but the fill plug leads to a tube about 70mm long inside the transmission. This sets the factory level for fluid in the trans (above the join line for the pan!) and will take about 3l to fill. You then need to connect your fluid pump to the fitting via a hose, and pump in whatever amount of fluid you removed (maybe 3 litres, in my case 7 litres). If you put in more than 3l, it will spill out when you remove the fitting, so do quickly and with a drain pan underneath. Once you have pumped in the required amount of clean ATF, you start the engine and run it for 3 minutes to let the fluid circulate. Don't run it longer and if possible check the fluid temp is under 40oC (Ecutek shows Auto Trans Fluid temp now, or you could use an infrared temp gun on the bottom of the pan). The manual stresses the bit about fluid temperature because it expands when hot an might result in an underfil. So from here, the factory manual says to do the "spill and fill" again, and I did. That is, put an oil pan under the drain plug and undo it with a 17mm spanner, then watch your expensive fluid fall back out again, you should get about 3 litres.  Then, put the drain plug back in, pump 3 litres back in through the fill plug with the fitting and pump, disconnect the fill fitting and replace the fill plug, start the car and run for another 3 minutes (making sure the temp is still under 40oC). The manual then asks for a 3rd "spill and fill" just like above. I also did that and so had put 13l in by now.  This time they want you to keep the engine running and run the transmission through R and D (I hope the wheels are still off the ground!) for a while, and allow the trans temp to get to 40oC, then engine off. Finally, back under the car and undo the fill plug to let the overfill drain out; it will stop running when fluid is at the top of the levelling tube. According to the factory, that is job done! Post that, I reconnected the fill fitting and pumped in an extra 0.5l. AMS says 1.5l overfill is safe, but I started with less to see how it goes, I will add another 1.0 litres later if I'm still not happy with the hot shifts.
