Good luck with it - if the N1's enabled you to run 137mph then these should give you enough power! 1:02 at Wakefield will be blisteringly quick on a short tight track.

How much boost you going to run and what power are you aiming for with this set-up?

Great to see you guys are going all out and not doing it half arsed!

YEAH 1:02 is the goal whether we can achieve it is, another question.

looking for power around the 450 - 470 awkw, hopefully with power all the way through to 8500 with a 9000 rpm limit.

should have rotional idle and anti lag switched on for friday too, not aggressive though.

awsome to hear Andrew - we werent to sure about them but that's very encouraging and the new dumps are heaps better than the old set up. we picked up 10 odd kw's at 4wheels from the side pipe and lost about 8-9 kilo's.

the -5's are the smaller style of the n1's right? the .42 instead of the larger n1 which have .60..

i beleive thats the same i have on my car, tho they were rebuilt and a 5mm larger front wheel was added.

just reading garrett now, it appears in your case its reversed. you have the .60.

They are identical to the 2530's except they are .62 instead of .63. But having used both types in the past it is amazing how much of a difference in response the -5's have over the 2530's with no difference in top end at all.

Is the intercooler piping going into and coming out of the turbos an off the shelf product or custom?

thanks for taking the time to answer everyones questions, its appreciated.

hi mate

yes the piping comin off the turbos, is off the shelf greddy stuff, good gear too!

and no problems with the questions, anytime, collectively there is a whole lot of knowledge on this forum!!

update (just got home)

car has been run in for a few hundred km's, was an interesting drive on the backroads!

back on dyno tomorrow for full tune and see what power and response we can get.

cheers russ

Yes , we have changed from the n1's, will find out if thats a good thing soon enough.

we stayed 2.6ltr because we want to rev it, and feel this is a safer option in that area as piston speeds increase with lengthening the stroke. fine for drag and short work but not as nice on longer distance stuff, i was lucky enought to be able to speak to the tomei crank engineer for a little while about the cranks and set ups while i was in japan, which was very interesting.

cheers russ

eh? you speak japanese russ?

or is that hes fluent in the savage tongue??! :P

so if i've previously had the .42 version with now a 5mm larger wheel where does this leave me?

with a strange turbo.... lol

A/R and wheel size are not the same thing by the way.

basically you now have one of the small n1s but with an odd size wheel in it. could be better, could be worse. hard to say.

yes there was a long wait on standard replacment from garrett, so 5mm larger was the closest size up. tho i think it was the whole cartridge replaced..

its so much better now where i lost a bit of midrange/top before i've not got a smoother powerout put all the way thru.

i'm done hyjacking!!

Go team Australia!!

whos the english mob going to tsukuba??

okay guys,

update

todays test was an absolute success and was also vital to find out where we are heading!

we broke all our previous PB's, by large margins( the day was very hot, track temp was 52 degrees, so there will be even more in it)

sprint 53.84 !!

national 1:16.6 ( and was held up a fair bit)

car was running 244kph on the front straight !! (on radar)

we had a power steering belt come off in the afternoon and give us a scare as it took out the dry sump belt,

(luckily it warns you straight away as the steering goes heavy and mark shut it down before we had no oil pressure and the car was on decel)

also played with suspension and alignment and got good results.

this is exciting as the power has not been increased yet over the old engine setup (rpm has though to 8500)

i will have some pics and vids up over the weekend( too tired now)

cheers russ

i run a hobbs switch (monitoring oil pressure) that triggers two relays...one to cut fuel the other ignition when low oil pressure is seen. It saved our last engine when the oil pump disintergrated.

Well done on the progress guys...I suppose you and Mark are giving Tsukuba a hammering on Gran Turismo 4

sensational.

will the car be back at QR again before you go?

Also when at Tsukuba, do you plan on letting a Japanese driver with much more experience at that circuit have a steer?

Awesome time Russell!!!

Same question as above, will the car be back at QR on a weekend for the rest of mere working mortals to drool :)?

Dirt, can you provide some more details on the parts used and the installation detail? Would you be keen to produce a kit for me/SAU members?

    • I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.  
    • Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days
    • It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
    • I assume clearances were all a-okay?
    • Shock tower brace is in +5Kw....LOL
