Thats on turn 3 (immediately after pit straight). The track diagram doesn't do that corner justice, it is a lot sharper early on, then the radius drops rapidly. Gotta brake deep into it, then get on the noise as you apex :cool:

No interstate racing as yet, my job has me away from home 6 months of the year at the moment. Will be doing Dutton, maybe Classic Adelaide, and some track days interstate in the next couple of years though....

hmm would love to see your car at the track..like it would be very similar to our race car..But we have gone all out now with dry sump setup and massive rollcage..Can I ask what ECU and turbos you are running?

The dutton is off tap I just did the NSW round in Nov..I think your more of a Superlap kind of guy!!!!

Dutton is more orientated on motorkana and hill climbs I was a bummed at the lack of good track time and was pissy 2 x lap dashes.. Classic Adelaide would be awesome I want to do that but just be a navigator for my first time..

You would like the SAU Vic track day they awesome peeps and have good tracks over there will be more than us here in NSW soon with Oran Park closing :yes:

Nice Pics DSTROY !!

I just realised your car is basically a GTR :cool: Nice work!! Are you running Single Turbo on the 26??

Andew just installed a pair of GT2860-5's on my car at the start of the week. and im so happy with the improved power :yes:

Google earth FTW!!!

.....Can I ask what ECU and turbos you are running?

I'm running a PWR FC d-jetro and Trust T517z 8.0cm turbos. Had them rebuilt with oversize thrust bearings for when I turn up the boost and add E85.......

With that power i had street tyres and did a 1.25.00 and i try'd not to rev it over 7000rpm

This time i have 300kw, semi slicks, half cage, and i want to fit a oil cooler before i go out. I don't think I'll be running it at full boost though.

Hey was that 1.25.00 an official time ?

Yep once again its a good idea. Close to stock power levels will also benefit as your intake system will not injest oil mist from the head - which effectively lowers your octane rating of your fuel air mix and will bring detonation on earlier. With a bit of boost on board, you will get blow by your rings and oil controls rings, which pressurises your sump and therefore head, and will breath oil out of your rocker cover breathers. Installing a catch can, whether it be with a return to sump a la nismo one, or simply catching the oil and seperating the air (to atmosphere) will negate the above mentioned problem.

One thing to add about catch cans - The non atmospheric vented ones are totally regency friendly. The autech one is particularly good as its just a cylinder that sits on top of the engine and returns straight back in...

I'm going to grab one of these when I grab turbos cam gears and cams. Will get a sump baffle before I even consider taking it to lala, and thats inspite of having an oil relocation and cooler kit installed already. I use the car as a daily so I dont wanna go fooly hektik (bahaha). Sump baffle and head baffle and catch can should be OK with N1 spec turbos and water pump

I'll get there eventually... I just need someone to buy this 2nd hand liver I have for sale....

Reading this I realised that as I want to getting into track work at some point that this would be a good addition to my car - but then I started contemplating defects & Regency. Our cars are a big enough defect magnet without adding something that is gonna cause more woe - and almost everything I'd read had shown most catch cans seemed to be defectable and very illegal. But then I saw:

... But noticed they're pretty much RB26 only (at least based on the description), and that if it did fit to an RB25 that it would stand out as a defect magnet and require removing the engine cover off of an R34 RB25DET (like mine).

Are there any other options in a similar vein that would fit an R34 RB25 (without removing the cover preferably) and that aren't gonna be so obvious whilst still remaining legal?

You could just get a custom one made - any automotive alloy fabrication shop can do it for you. Then you can hide it, or paint it black and run black lines to further stealth up the installation. Isn't it funny - we modify our cars to be suitable for track work, so we can get off the street and enjoy our car in the safety of the race track, and due to our outdated defect system it discourages us!! Talk about a self licking ice cream......

They're a great idea Ben and combined with a front tank (either atmo or plumb back), work very well.

Problem is, when using them on their own and as much as the overhead tanks can catch a fair bit of oil, after only a couple laps of lalla, they still allow mist to be thrown into your FMIC.

Andrew has probably the best solution with his setup, which if I remember correctly, runs both tanks plus all the internal oil mods.........Jess (sinful) also runs both tanks.

The other tank you speak of, is it running the Autech overhead tank as well as a normal oil catch can, or the other tank you speak of radiator breathers like: http://justjap.com/store/product.php?produ...=314&page=1 ?

This might be helpful for your rb25: http://justskylines.com/skyline/knowledgeb...k_plumbing.aspx

On mine - the overhead tank feeds another tank instead of back into your rear turbo inlet and PCV valve like the one pictured from just jap. This secondary tank sits in the position of the battery and vents air to atmosphere and feeds oil back into sump.

Sounds interesting, can you take a picture of your enginebay, having trouble trying to picture how its all plumbed in my head

    • Cheers. Skyline is back on the menu, can’t get rid of it. It’s like a child you don’t want, or herpes 
    • 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.
