Im hoping the turbo does turn out to be a good thing and that ive made the right choice and im all bout midrange and the smile it gives me with my car :nyaanyaa: haha

ive heard joeyjoe fella using 550cc injectors with E85 making 320 or so rwkw my car is purely for thrills so fuel economy doesnt come into the picture for me.

Im a plumber by trade( i do have a good mechanical aptitude tho) :wacko: but im wondering if making extra power by changing fuel as apposed to mechanically I.E( more boost bigger cams etc) is it making my engine more reliable???? If that makes sense? haha

Hamish is doing this with a Pro S not a KAI

The KAI has proved disapointing in comparison. I pulled 243rwkw on monday with my new front cover. Mind you I havent pushed the tune yet (there are reasons behind this) but its a very slight gain over the standard front cover and its got a bit nicer curve

Just so you know, you wont be seeing 320rwkw on E85, the KAI is fairly more responsive at least by the looks of it, More like GT-RS sort of driveability

So he prob will get hes target of 270 on e85. Im running 555 also and making 307 kw. If you want to go down the sensor path its not as easy just hooking up the sensor. Youll also need a compatible ecu link, vipec etc. Theres a whole thread on it if you search.

Sorry mate, just read that Advan was doing the work.... if your wanting to get the ethanol sensor sorted out speak to Yavuz at Unigroup engineering. I have had brief talks about doing this to my car and Yavuz is all over it and has some ideas on how to tackle it. He knows his Links as well which is a plus

or go to JEM. they have fitted a number of cars with the zeitronix E content sensor (they are dealers for it). and tuned many cars on E85/Eflex etc now. I would talk to those guys.

I've got my GTR on E85 and i had changed injectors, added another fuel pump and retune.

seriously, there is no point running E85 for "safety" its costly to change injectors etc for little gains if your motor, turbo, AFM's or other gear are going to limit you to power you could easily achieve on PULP

i had my GTR running 21psi on PULP and getting 350rwkw, then went to E85, upped the boost to 24psi and got 370rwkw. the boost wont hold until redline it drops off to 20 or so PSI so that's why there is no huge gain in the top end. but midrange is crazy! and thats where most driving is done. torque difference is great.

then again, on my setup i was nearing the limit of PULP with the parts i had. if i had to do it again i probably wouldnt bother. the limited station and less ecconomy means with a spirited hills run i have a 20L jerry can in the boot just to make sure i don't run out of fuel.

for what you've listed, get your turbo, and injectors fitted and tuned on PULP and enjoy for a while and save up for E85 if you feel the need.

what turbos?

what turbos?

turbo's on mine are -5's

I'm thinking maybe an exhaust leak is contributing to the boost not holding at 24psi. because after a hard few goes at WOT on high boost i can hear a high pitched whistle coming from the engine anytime the turbo's spool.

i'm also getting very small amounts of blue smoke out the back of the muffler when i back off the throttle, some have suggested maybe turbo seals?

Hey cal spewing bout the turbo mate im not chasing that much power so i wont be too disappointed by not making that kinda power mate

So changing the front didnt get you more power mate?

ATM its a 3kw gain. But as I said I havent touched the timing really, just trimmed the AFR's to be alright.

So there might be a little more power in the tune, but the way I've modified it, it may have a slight leak so that could also be causing a loss in power (it is a temporary thing at the moment)

The main difference is overall driveability, it feels alot better on the street, slightly more responsive (not a great deal but) and I was having an issue with what sounded like surge at around 16psi in 5th gear (short version of what was happening) which has disappeared now.

So basically at the moment its an improvement. But its not on par with the Pro S

Yeah im thinking bang for my buck at the moment and since that i have my fuel injectors and other fuel system parts a servo a km away from my house that has E85 im thinkng once my turbo arrives and i install that and my fuel injectors Z32 afm im gunna need a tune anyways so its not gunna cost me any extra to run E85 and get the extra midrange plus the HP i was chasing with the Kai turbo kit since it doesnt seem to work as good as the Pro S kit that i just couldnt get my hands on! :domokun:

Lol thats ok mate if i go down the ethanol sensor and the link computer option i will prob get my link from Advan which im prob not gunna do now cos if my injectors will see my HP target im chasing ill be happy without spending the extra $$$$ and using the nistune

could be. still 350kw on pulp is right at the good end of power for -5s on 21psi so things seem fairly healthy. I would have expected a bit more like 380kw or so though with 3psi more boost AND E85 change. still I wouldn't be too concerned. fix the exhaust leak though, they certainly don't help.

Hrmmm whistling noise when the turbos are on boost..have a read of my thread from yesterday lol Mine was the gasket between the turbo and manifold :/

Im a bit annoyed with it really, I wanted to run 270rwkw on 98 and then when/if E85 ever comes out on pump where I live I was gonna have a "Race" E85 tune and then a daily tune that would run 270rwkw just on less boost.

At the moment Im just making 243rwkw on 18psi. Its disapointing seen as I ordered a Pro S at the time the started discontinuing them so I was told the KAI was just as good if not better. Doesnt seem to be the case

    • Not that I know from experience, but in theory you'd want your gate spring to be as close to target pressure as possible, so you'd go with the higher gate spring?
    • Before I commit to it as I already have the wastegate off the car, would you change it to the 9psi spring instead of the 12, or whack it back on now and try your suggestion?   Edit: Actually I might just swap the spring and see what the logs say after another few pulls, as we know it's still spiking without the Mac valve in the picture so I need more data without the Mac valve trying to combat the issue.
    • Sounds good Hmm suppose the main thing is, how much do you care about this car? The filler doesn't make for a very good water barrier lol. If there was a tiny little bit of rust forming now, that in 3 to 5 years time becomes obvious under the paint (starts to bubble up), would it bother you? 
    • I already have the ability to datalog the voltage... what I can't do is correlate it to what the gauge is showing when I'm looking at the data at a later date. Or something like this. Except getting the oil to 125C+ involves me going 200+kmh at the track so you can imagine this is a little tricky unless I do something like note what the voltage is when I am at the top of 5th gear so I have a point to reference on. Drove car today. O2 still reading richer because hopefully not a leak instead of massive restriction I've introduced. Car really doesn't sound like a LS. It's quite strange. Pulled a bit of fuel out up top. This does potentially explain why my spark plugs looked like the car was running pretty over-rich. If I was tuning it to a ~12.7 which in reality was far richer than that in the past. It will be handy to have the dyno WB to compare my WB to to compare notes that's for sure. At this point I'm happy to just sit in the passenger seat and tune the thing given I've got about 7 million hours on the platform lol.
    • Yeah I understand you have to pay for an updated map or subscription service or something. But I can't even find a current map for Australia. My map is dated 2017, but didn't this car version still sell in Australia until 2021?   Also, just as an aside, the navigation system warns you of traffic incidences ahead.....why would they include that on a map they knew is not receiving live information. I am forever going to be warned of an incident that probably existed for 30 minutes 8 years ago.
