hey guys,

got my car back from gtech performance on thurseday, car is tuned on e85 fuel running a vipec ecu the car made 317.1 rwkw

they did get it to 328rwkw but wasnt very safe as there was a missfire anything over that and also injectors are at 85%.

good this is when u pop the bonnet you can hardly tell anything is done to it, apart from the big ass 50mm pro gate :D

car is not complete yet but safe to drive on this power level, will be going back there in February when they open up agian for bigger injectors, different ignition setup and another tune

lets see how she goes.

i will be putting standard supsension in the car soon enough, a set of slicks and taking it down the strip for some 1/4mile action.

heres a pik from there christmas party the other day, and also have just a sample video of the car (nothing major just a bit of up and down the street screaming)

ps. the r33 rims are only on the back as the 18s had wires hanging out and wasnt suitable for the dyno.

for the fuel setup i have 2 x bosch 044 fuel pumps, surge tank, 800cc injectors (or there abouts), surge tank, braided fuel lines in the boot, new fuel lines from boot to fuel rail, new fuel rail, vipec ecu, garrett gt3540, catch can setup,

and thats the basis really

e85 is only available at the hoppers crossing petrol station on old geelong road, pump number 10.

car is all over the road, but i cant even drive it really as i dont get my license back until 05/05

Ah nice work, I am thinking of upgrading to a surge tank, and considering replacing lines while im there, and mayb try e85 on a new tune. Do you need special ethanol injectors or pumps for e85? Or just a higher flowing system?

in regards to whether you need special injectors, im not sure, but as u can see i have 2 bosch 044 fuel pumps which u can get most places.

the thing to remember though is that e85 burn ALOT quicker.

not sure exactly, as i got it done as a packege mate.

nytsky - i know that e85 needs a much higher cc injector and there dyno is quiet a low reading dyno, but as i said its not complete 100% so everything will be sorted out in 6 weeks,

and as they say, a dyno should only be a tuning tool so im hanging to take out to calder/heathcote and see what mph/et i can get.

feels absolutely mental :D, couldnt be happier.

GT35 only made 320rwkw on E85? How much boost is being used?

I ask because you can virtually do that on PULP, with a 3076!

Regardless of the fact it is a low reading dyno - cause lets face it - every 2nd post says the dyno they used reads low these days.

Indeed take it to the track, i would imagine the MPH will match 320rwkw. However it should be 400++

you definately dont need to upgrade lines.

Seen plenty of cars make 450rwkw+ on factory Nissan lines. More about the fuel pump being decent :D

r31 nismoid, as i said, its having missfire issues and the tuning is not finished, also as i said dyno dont mean anything, its about the mph thats what im waiting for

the turbo is a gt3540 with the .64 rear and on 18psi boost

i run 323 rwkw on e85 on virtually the same boost and a smaller turbo...

as for fuel, 2 x 044's and a surge tank are not req'd (nice to have tho)

i run nismo 555 injectors, a nismo drop in fuel pump and stock fpr, lines, rail etc

What did the Vipec ECU set you back?

Vi-PEC plug-in ecu is $1881 inc GST

As a side note...

we put some new Injector Dynamics 1000cc jobbies in a completely standard car the other day...the Vi-PEC controlled them beautifully. At idle the AFR's didn't jump around at all, i reckon we could have put 2000cc ID injectors in and it would have been just as good. These new injectors we are getting out of the States are the latest technology and when driven by the Vi-PEC are very impressive indeed.

You might want to think about reading the post again, Bas stated the car IS NOT COMPLETE, 317kw is the current tune as they had injector issues, as for 400++ wow, stock bottom end, no worries :)

Did you read? There were no injector issues at all. 85% duty is not a worry... read on and you shall see why...

Now further detail is provided... a GT35 in .63 is pretty much at the limit @ 330rwkw miss firing aside. You'll also probably find the miss firing could also be induced by .63 rear.

It is horribly restrictive for that compressor.

There should not be issues with fuel because of the following...

1. 800cc/E85 is more than enough for 370rwkw+

2. Two Bosch 044's with E85 will support 400rwkw+

Given the above... You'll never reach those limits with a GT35/.63, so all is well and good. Leaves one issue. Miss firing.

Would likely be coil packs and/or plug choice, but i wouldn't be surprised as i said above, if it was indeed the rear housing choice playing a factor.

ALL ISSUES ASIDE, here is a little clip of what the car sounds like.

as i said, im extremelly happy with how it has turned out and cannot wait till its finished, so we will see what happens once i take it to calder.

Thats intersesting i would have thought that turbo be good for 380+ on E85 considering my little HKS 3037 .68 has seen 350 on numerous dyno's.

What mods are used to make this power? Have you done anything special to be able to run e85?

And where abouts do you you get e85 in melb from? Last I hered there were only 2 servos selling it.

The other servo that has e85 is fueltown(heading towards the city) next to southland on nepean hwy. Look for the big banner cant miss it.

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
