any good link tuners in sydney??

im beginning to think e85 and its availability issues will be the end of the good old pfc

I havent read the whole thread but send it to Unigroup Engineering in Girraween. Yavuz tuned our link G4 and was very impresed with it. Add to that the fact he really knows his shit :D I have been ising them for years and woldnt take my car to anyone else. And i use to work for another big name GTR workshop in Sydney

I am actually going to speak to him about using this Ethanol sensor in our car this weekend as Sydney only has a handfull iof servos with E anything and to do away with the laptop on the back seat would be awesome :D

I couldnt tell you how it compares as i havent seen those turbo's on a similar engine. The head has a fair bit of port work done. I know we are quite happy with the response we have. 22psi at a little over 4000rpm is pretty decent.

Was hoping to have a cracck at 140mph this weekend but the drag days been canned :(

T78's are one of my favourite rb26 turbo's... when set up right they really work nice.

hey you guys so i have some questions.

I am running a 2.7 RB with an HKS F-Con V-pro with 1000cc HKS injectors. We want to run E85 with the Flex Fuel setup since its impossible almost to get race fuel here in California (to many forms.)

So with that in mind we are thinking about running 1600cc Bosch Injectors. Not sure if the HKS unit can control them at idle??? anyone have any luck.

I know a lot of you will tell me to use ID2000cc but honestly thats about 1200USD for a set and I just cant justify that after already spending that much on the 1000cc HKS injectors.

So a couple of questions:

1. Whats the most amount of boost you can use on e85?

2. Why do you use the GMC Flex Fuel sensor over the Ford Sensor as its seems to be 5 times the price.

3. Can you run E85 with Methanol and what are the benefits.

4. Instead of replacing the HKS 1000cc injectors could I just add 2 additional injectors to the intake manifold?

Thanks you guys. This thread is very informative.

What's your duty cycle % thingy with the 1000cc's at the moment? i'd be thinking you might not need bigger. And more importantly, what turbos?

1) how long's a piece of string? i would say it rests entirely on your current setup

2) link to Ford sensor please, it might be a lot more economical for people then if it's cheaper. I wasn't aware of any other options at the time other than getting a $50 s/hand one from a wrecker.... which i didn't want to take the chance.

3) No idea

4) How do you know you need to replace the 1000cc ones?

in other news, i have been mixing and matching a bit around town but where the Flex setup came in ultra handy recently is on the drive back from Shepparton. Motorsport even out there, car was on E-flex on the way out, took a couple jerry cans for the event (and to top up after the drive out), running a bit low on fuel on the way back though, no e-flex left in cans, no worries, pull into the BP at Wallan, throw in some 98, smooth as you like spirited entry to free-way on exit and cruise home, without a hitch :) Easy, simple and works flawlessly :)

I highly recommend :D

That link seems to show an aftermarket sensor...

Quote: How does it work?

Simply put, our sensor duplicates the signal that the OEM sensor produces. Your engine control module sees the signal it expects and it clears the engine failure codes. Our Flex Fuel Smart Sensor is designed to use with Regular Unleaded Gasoline which contains up to 15% Ethanol. We do not recommend installing our Flex Fuel Sensor and continuing to use E85.

Not sure what they mean though.

Didn't read down as far as you did - looks like a fake - definitely no use for flexy system :(

Its not actually a flex sensor by the looks its just a signal generator that tells the ecu its constantly running regular unleaded... The signal may be tweaked slightly to compensate for the 15% E mentioned.. Id assume the ecu would go into limp mode when the factory sensor shits itself to save people money this is an option especially if your not running high % ethanol mixes..

      V37 Suspension change

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before

      OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:

      R34 manual conversion speed signal wire finding, need help

      By GTSBoy · Posted

      Yes. Autos typically work from the speed sensor on the pinion shaft of the diff. I also think that even if you have a proper speed sensor for the bog manual in the manual box, that the signal it outputs is not compatible with the auto dash anyway. You should consult that manual (the book, not the gearbox).

      And I just realised that that advice is slightly nonsensical for a GTR, because you need 2 of them. But it is otherwise true.

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

      By Duncan · Posted

      Having had a reasonable look at the car, I'll be able to remove the (one time) rams and retract the hinge (they are held in the down location by a tiny (m3?) sacrificial screw) which will get it physically back in shape. From there if you remove the rams you need a resistor to turn off the airbag light (as Mark said, there are plug in kits and I might go that way because its reversible). And...per all the threads on here, even if you have the resistors to turn off the airbag light, the bonnet light will stay on as it writes to the airbag computer history - that is either replace the airbag controller, reprogam the EPROM (if I can work out how), or remove the globe from the dash. Having seen how sensitive this system is, if I had my time over I'd pre-emptively remove the rams, even on a road car, because this is all a very unnecessary pain in the arse. Reminds me, time to go and have a look at the Fuga too....
