A sensible setup. 250-300kw is really the perfect setup for the 25, not so much that its unusable without jail time and sensible enough that you can still use it normally without it being a complete pig.

My evo 7 had a 3082 with a 1.06 rear on it, it was a complete dog below 4 and didn't hit full boost until 5.5. Ridiculous turbo choice by the previous owner, hilarious and fun but ridiculous none the less.

Was much better when I changed it to a high flowed stock turbo, was all on at 3500 and made almost the same power.

Mid size high flows are the way to go - improve a vehicle's power decently and leave it at that for reliability, tractability and usability.

When choosing my turbo I drove Hypergear's 340kw 33 that took until 4500rpm to actually get anywhere and then it wanted to eat a gutter. He asked me if I liked the power...I said no man, make me a turbo that comes on quickly instead of this, so he did. Haven't looked back - convinced my turbo is what these cars should have come with from factory!

There is more to performance than dyno charts

I just said centrifugal chargers have their benefits which aren't immediately apparent.

Midrange kick is pointless if you are breaking traction there. Seperating your stuff from being tied to your exhaust manifold is also nice.

The smart answer if modding a RWD skyline for power is immediately LS convert it.

Does it ever bother you that there are absolute f**kwits out there who wouldn't know a tenth of what you do about cars, driving 500kw GTRs up and down bypass that never miss a beat

I must agree since i also have a highflow. aka - best skyline turbo ever, lol.

But I wouldn't want a 250km range or cold start issues :P

300km thank you very much. No cold start issues here, even on freezing cold mornings. Getting the cold start crank and post crank settings right is the key to cold starts on e85. Flex fuel = best of both worlds.

I live right next to Glenny Kebabs and I hate this quite a bit at times :P (so many stanced golf R's holy shit)
I originally wanted to buy a Supra and could have, back in the day.
Would have done a lot more driving I assume, but wouldn't have (needed to) learn anything at all.
There is an element of fun to learning stuff, and there's always more stuff to break learn from

Only problem with E85 is that it allows you to push so hard on the tune you will break the next thing up the chain as it will never ping.

This ain't so good if you have metal head gaskets, head studs, stronger pistons, rods, crank because when they aren't the weakest point you end up Gregging it™

98 isn't a bad idea as it stops you from going too insane, its a built in safety measure of sorts to make sure the rest of your setup is actually going well. E85 is like fuel-steroids. You can get the 'right' power on 98 in a Skyline at least to the point where everything else starts to become a limitation. You may not get forum and instagram #efame but you will be able to have fun with the vehicle and have a modicum of reliability and do more than hardpark it and fap over a dyno sheet if you go full retard with timing. (or full advance on timing, really)

Yeah flex seems like a good idea on paper, I'd want to have complete confidence in the tuner though! 

I think an STI would be more like 250km, those tanks are small af. Been looking into getting a Subi

Going to remain silent on the Gregging it™ front, as the last track day that we were at together didn't end well for me and you came out unscathed

Whaaaa? What happen?

Everyone I was with that day was super happy they could lend the helmet you offered. You're the shining pinnacle of "Track day people are awesome!!" in their eyes. I did not know things went badly. Please tell me you didn't split a block due to aggressive timing due to magic E85 :P

For me, it's been just as good in practice as it has been on paper. As far as the tuner, you'd want to have confidence in a tuner doing anything to your car even if it's not e85 related. Since going e85, ive had no issues to speak of. I run a tank of 98 every 3-4 months, followed by a change of fuel filter. Has worked well so far. I also drive my car daily, so the fuel never gets enough time to absorb water and turn things to shit. Knock on wood that by saying that i wont be in the gregging it(tm) club.

Boost or Intake leak = overboosting turbo (correct psi by the time it got to the engine) = overheated turbo = warped / cracked exhaust manifold. My day was over by midday.

No worries about the helmet, never put blocks in place that stop people from getting out onto the track. We've got future track day participants to take care of!


Edit: 

 

88e positive news from update = up it goes, tomorrow back down again 

Give it till the 22nd for results... At the moment its happy building solid base, im happy it hasnt gone spastic high and then everyone dumps within 24hours.

    • Hey Dave, welcome aboard! Good to see another soon-to-be Stagea owner here. The wagons are awesome — plenty of space, still got that Skyline DNA, and loads of potential if you’re into mods. Definitely post up pics when you get it, everyone here loves seeing new builds. What model/year are you looking at?
    • See if you can thermal epoxy a heatsink or two onto it?
    • The other problem was one of those "oh shit we are going to die moments". Basically the high spec Q50s have a full electric steering rack, and the povo ones had a regular hydraulic rack with an electric pump.  So couple of laps into session 5 as I came into turn 2 (big run off now, happily), the dash turned into a christmas tree and the steering became super heavy and I went well off. I assumed it was a tyre failure so limped to the pits, but everything was OK. But....the master warning light was still on so I checked the DTCs and saw – C13E6 “Heat Protection”. Yes, that bloody steering rack computer sitting where the oil cooler should be has its own sensors and error logic, and decided I was using the steering wheel too much. I really appreciated the helpful information in the manual (my bold) POSSIBLE CAUSE • Continuing the overloading steering (Sports driving in the circuit etc,) “DATA MONITOR” >> “C/M TEMPERATURE”. The rise of steering force motor internal temperature caused the protection function to operate. This is not a system malfunction. INSPECTION END So, basically the electric motor in the steering rack got to 150c, and it decided to shut down without warning for my safety. Didn't feel safe. Short term I'll see if I can duct some air to that motor (the engine bay is sealed pretty tight). Long term, depending on how often this happens, I'll look into swapping the povo spec electric/hydraulic rack in. While the rack should be fine the power supply to the pump will be a pain and might be best to deal with it when I add a PDM.
    • And finally, 2 problems I really need to sort.  Firstly as Matt said the auto trans is not happy as it gets hot - I couldn't log the temps but the gauge showed 90o. On the first day I took it out back in Feb, because the coolant was getting hot I never got to any auto trans issues; but on this day by late session 3 and then really clearly in 4 and 5 as it got hotter it just would not shift up. You can hear the issue really clearly at 12:55 and 16:20 on the vid. So the good news is, literally this week Ecutek finally released tuning for the jatco 7 speed. I'll have a chat to Racebox and see what they can do electrically to keep it cooler and to get the gears, if anything. That will likely take some R&D and can only really happen on track as it never gets even warm with road use. I've also picked up some eye wateringly expensive Redline D6 ATF to try, it had the highest viscosity I could find at 100o so we will see if that helps (just waiting for some oil pan gaskets so I can change it properly). If neither of those work I need to remove the coolant/trans interwarmer and the radiator cooler and go to an external cooler....somewhere.....(goodbye washer reservoir?), and if that fails give up on this mad idea and wait for Nissan to release the manual 400R
    • So, what else.... Power. I don't know what it is making because I haven't done a post tune dyno run yet; I will when I get a chance. It was 240rwkw dead stock. Conclusion from the day....it does not need a single kw more until I sort some other stuff. It comes on so hard that I could hear the twin N1 turbos on the R32 crying, and I just can't use what it has around a tight track with the current setup. Brakes. They are perfect. Hit them hard all day and they never felt like having an issue; you can see in the video we were making ground on much lighter cars on better tyres under brakes. They are standard (red sport) calipers, standard size discs in DBA5000 2 piece, Winmax pads and Motul RBF600 fluid, all from Matty at Racebrakes Sydney. Keeping in mind the car is more powerful than my R32 and weighs 1780, he clearly knows his shit. Suspension. This is one of the first areas I need to change. It has electronically controlled dampers from factory, but everything is just way too soft for track work even on the hardest setting (it is nice when hustling on country roads though). In particular it rolls into oversteer mid corner and pitches too much under hard braking so it becomes unstable eg in the turn 1 kink I need to brake early, turn through the kink then brake again so I don't pirouette like an AE86. I need to get some decent shocks with matched springs and sway bars ASAP, even if it is just a v1 setup until I work out a proper race/rally setup later. Tyres. I am running Yoko A052 in 235/45/18 all round, because that was what I could get in approximately the right height on wheels I had in the shed (Rays/Nismo 18x8 off the old Leaf actually!). As track tyres they are pretty poor; I note GTSBoy recently posted a porker comparo video including them where they were about the same as AD09.....that is nothing like a top line track tyre. I'll start getting that sorted but realistically I should get proper sized wheels first (likely 9.5 +38 front and 11 +55 at the rear, so a custom order, and I can't rotate them like the R32), then work out what the best tyre option is. BTW on that, Targa Tas had gone to road tyres instead of semi slicks now so that is a whole other world of choices to sort. Diff. This is the other thing that urgently needs to be addressed. It left massive 1s out of the fish hook all day, even when I was trying not too (you can also hear it reving on the video, and see the RPM rising too fast compared to speed in the data). It has an open diff that Infiniti optimistically called a B-LSD for "Brake Limited Slip Diff". It does good straight line standing start 11s but it is woeful on the track. Nismo seem to make a 2 way for it.
