Hi all,

I've just got my car back after some major modifications with a healthy 272.9rwkw before 6000 rpm - obviously my crappy 235s have no chance of holding it in 1st or 2nd (barely in 3rd) so I can't get most of my power down.

The search is on for some new rears - to match the fronts i need to go 265/30/19

I was thinking of the Nitto NT05s but they don't come to Aus in this size apparently...

The two others i'm tossing up between are the Pirrelli P Zero Rosso and the Yokohama Advan AD08 - prices for these are around the $600 - $650 mark each (ouch :) )

Anyone have any thoughts?

Cheers.

take a look at the federal 595 RS-R tyres, they are fairly cheap for a decent road legal semi slick.

otherwise check out http://www.tirerack.com/ they deliver internationally, though expect ~$200 for freight and a $30 international money transfer charge when you pay for them, friend just got some 265 17's Michelin Pilot Sport PS2 tyres for just over $800 delivered, the cheapest price he could find one tyre for in australia was just under the price for 2 from the USA even with delivery etc.

heaps 2 pick from

the old 3076r made 272kw.. what boost?

old 3076? I assume you aren't meaning the 5 blade one? Mine's a spankin new 6 blade.

272.9rwkw @ 18psi - fairly conservative tune, max power is in before 6000rpm all the way to redline so i could lean on it a bit more.

It looks a bit lazy coming onto boost but it makes the numbers.

I reckon there is more to be had in the mid range with tweaking/checking boost control and wastegate pre-load.

Have you modified your suspension? How much rear camber?

My R33 makes very similar power (allowing variations for dynos) and I have almost no issues getting power to the road with regular road tyres. I have the old SK GB suspension (bilsteins etc) and I have tweaked the settings around to suit me.

good result... was this internal gate?

Also.... I went and got new tyres the day before i started on my 3076r build because I knew how the after effect was going to be...

I have I think nexens (i'll have to check.. cant remember the brand) was 600 all up for 4 new tyres... 235/40/18s...

They hold on pretty well for what they are and cheap to replace! even when i had my car in 2wd they were good.. in awd theres barely any let go...

Yup .82 rear.

The boost does look a little slower than some other graphs - although we mapped it up against an R33 with almost the exact mods on the dyno charts and mine made 30kw more throughout the whole range and almost 70nm more torque throughout until both making the same power at redline - and the 33 was on 21psi. Thinking that's the NEO making the difference.

I might just play around with the gain on the boost controller in small increments and see what I can glean re the boost delivery...

As for traction it is standard suspension with King Springs - thinking of going the pineapples. If i put my foot past 2/3 in 2nd it breaks out everytime around 4.5-5k. But they are pretty average Hancook 235s...

And yes it's internally gated - spent enough $$ without going for external!

I was really only after 240-250ish when i began this whole thing but thought i may as well get the best parts and see where i ended up... I think the 273 could definitely go up but it is a daily driver and i want it to last a number of years so don't want to lean on it too much...

yeh looks the goods, dif comes on slower being internal gated

im running brand new federal 235 40 18s 595 SS on the rear and in 2nd with 290rwkw i dont loose traction and thats tucking rim with G4 coilovers hard as lol.. HRMM

    • Was going to say the car pulls up nicely everywhere, especially going into that last long right hander before the main straight. Looks like a lot of fun.
    • 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
