Thanks guys ;)

Sure I can give you basics :P

It's an SR20VE+T now, big custom cams, sleeved / forged bottom end, modded Precision turbo on 6boost manifold, ported head, oversized valves etc, Bosch 2000cc injectors, custom plenum, Plazmaman throttle body.

sounds wicked. there is some cool stuff happening around the place with the SR VET heads going on to SR20s. but your thing is out of this world. I'd like to come check it out one day soon. :)

Thats awesome, its a PT6765 I'm guessing? The Precision and the FP-HTA billet turbos are wicked pieces of kit, good to see them catching on down this part of the world. I am hoping that soon I'll be able to report some results for a built RB25 running a PT6765 on E85... that should be quite interesting.

cheers mate, allways keen to try new things!

Yes i used to get 380 to 450km's to a tank with BP98 depending how i drove it. I came up with a magical number in my head when making up the map in datalogit on my pc at home which was spot on, and its no way near double then what it was, but i will say it is more then 25% consumption.

My gtr uses bout 20 litres per 100 ks I did a trip from.Brisbane to.tweed on.the weekend and.went through a tank in 180 km mind u its a very very heavaly modified engine

Finally joined the E85 club! RB25 Neo with super responsive turbo making 242rwkw on 98 and 279rwkw on E85! Very happy

Havent tried cold start yet but my idle is smoother than on 98! Thanks Trent from Status Tuning and Tao from Hypergear turbos!

Hi guys,

I just had my car run on a dyno on the weekend, it pulled 353rwkw @ 24.5psi

the AFR's were dead flat on 11:1

boost held strong to redline, only droping maybe 1.5-2psi from peak.

question is, is 11:1 AFR too rich for E85? i dont think there is much advance timing in the tune, maybe 3-5 degrees over PULP

turbo's -5's

exhaust 3in full system incl 3in decat

nismo AFM's

std airbox

K&N air filter

1000cc injectors

Nistune ECU

twin walbro in tank fuel pumps

ARC 70mm intercooler

silicone I/C piping

std cams (recond when engine rebuilt)

forged bottom end

Mines dump pipes

std manifolds

that's pretty much it

That is very low power for -5s on 98 fuel. I would fix whatever the issue is holding that back. Should be able to make around 350rwkw on 98 first. 318 is -7 or -9 power. Whatever restriction you have may be holding back your E85 results in a more significant way.

honestly in my experience it's in the ball park. having seen dozens of cars with -5s most often they make between 310 and 340kw at 20-22psi. 353kw on E85 is not bad. perhaps a little low but every car and every dyno is so different as long as it's performing it's not worth worrying about.

11:8 to 12 AFR is the sweet/safe spot. Leaning it out a bit will net you some gains.

    • Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance
    • My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..
    • The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.
    • Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????
    • Thanks Paul I reached out to Autotainment but they no longer work on JDM cars as the guy who used to do the work moved on and is no longer doing that kind of work. I am talking with Level Up Audio though.
