So currently putting a list together on what mods ile be doing to my 25, have a 8g budget im working with too achieve close too 400hp and build my 32 into a drifter, will never be rego'ed again.

currently im going with

definite mods

HyperGear G3 turbo

DW300 in-tank fuel pump

740cc Deatschwerks injectors

Maybe mods

EWP

6boost midmount

Greddy manifold

But im stuck deciding if i should go with E85 or a WMI setup, both have there pros and cons, for me E85 is harder too buy as im in queensland but the power gains and and anti det will be alot more then WMI, but WMI will bring my temps down, engine will run alot cleaner and is easy to get...or run 50/50 E85 and 98ron...hummm

any advice will be appreciated,

Thanks in advance!

you can easily run WMI on E85, but now your talking some serious power lol more than you will push from a G3

for a track dedicated car in a non E85 friendly area, WMI will be easier to make do with.

once E85 is easier to come by you wont be at too much of a loss to retune and on sell the WMI kit. The WMI kits are under $500 for something that will do the job.

Why is E85 hard to get for a track only car in brisbane? There's a caltex at goodna which sells it, you'd go past that on the way to QR. There's also one in ipswich itself, a few over on the bayside and one near mt gravatt.

WMI is a BC E85 or agrestic Oz [where E85 is unavailable] solution. If you have good access to E85 and never travel outside the metro area/s then use it - its cheaper and easier to set up than WMI. For all us erudites unable to take advantage of E85, WMI is the answer.

I think the question that determines which way you go is how often do you drive the car. A lot of k's will mean WMI.

I'd like to see someone try a little straight water with E85. You would spray 1/2 the volume that you would if using a WMI setup for the same power level. Around 400cc for 400kw atw.

The advantage I see is that you could run the E85 tune a lot leaner, into the 12.x:1 range. Which will help a little with fuel economy in the long run. I can't remember exactly, what he told me but Piggaz's car drinks E85 at a pretty alarming rate. Well over 10lt/minute at wide open throttle.

From what I understand about E85 tuning, rich AFR's under full load are needed to help keep detonation at bay and also to keep things from getting too hot. In this way E85 tunes more similar to pure methanol burning engines than ULP.

Im running a Microtech LT12s btw, its going to be a track car so distance isnt that much of an issue, you use around 45% more fuel when your on E85 because to get the same amount of energy from the fuel you require alot more, just like Avgas, i just dont want to have to bring 100LTs of E85 too every drift event lol

Can someone explain how you'd do the 50/50 ethanol mix, does this mean mixing fuel at home from a drum or would you have 2pumps at the servo, one for 98 and one for ethanol?

What kind of gains would you get from 50% mix if your making say 300kw with 98?

id say get 2 20lt drums and put both in your fuel tank, i wouldnt buy e85 from the pump, only the drums, i assume it would be simlar gains too straight E85 but not as much, would also require less fuel then straight E85

just go flex-fuel setup.

Ethanol content sensor

ECU with digital input (Link G4, some of the Haltechs etc)

And get some ID1000's at least, to leave you some headroom if you change your mind. Better injectors anyway.

    • Yes. You will need to get the original boost sensor and wire it in. That is.... if you plan to use a stock ECU - even a Nistuned ECU. The Nissan ECU will not operate correctly without it connected. And yes, it will do annoying stuff like you are experiencing. You will almost certainly be better off with some aftermarket ECU, than trying to hunt down rare sensors.
    • Ok so ABS/TCS is "not" the problem. Yeah i know now about the ABS with Nistune(i told that to the Nistune guy) but iam not 100% why or why i dont have ABS. ABS cube is in the engine (always has been) but i had braked couple of times rly hard and brakes just locked and scream. Does all Skylines have ABS cube? That boost sensor https://www.sau.com.au/forums/topic/367633-wtb-r34-gtt-turbo-pressure-sensor-pics-inside/ Is this it? I need to ask but i have a picture of engine bay and i do not see that (100% is not in that place) If i do not have this the car can do what mine is?(cutting around 4000 rpm) Here is the pic of my engine bay(only one i have) BUT i think i dont have that cuz loom was used from my RB20DE NEO and i know (obviously) that it does not have boost control or any wire to that...) so maybe that is the problem? (i dont know for 100% if that car where the engine is from had that)...but i dont have the loom from that
    • I'm with you here. It's either loom has an issue, OR, injectors are not functioning properly. It could even be they're just constantly dribbling, hence the wet, but not firing.
    • Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi
