Talking to Adam the car was still making power and on previous runs was still making power over 8,000rpm and believes had he been able rev it to 8,000 on the 27psi run it would have made at least 480kw

Bit of and update

I had an issue where every time I’d boot the car it would trip the engine protection and throw an oil pressure code, we thought maybe the engine protection was set a bit aggressive. 

we took the car for a drive with a data logger going and fair enough it was losing oil pressure rapidly, put an extra liter of oil in it and presto all fixed. Which shows the protection was doing it’s job perfectly.

Lesson learned that even with a baffle in the sump it’s still not good enough, something better is on the cards at a later time

Great to hear that the oil pressure warning was doing it's job.

What sump, baffles and oil pump, what is the oil breathing setup, and was anything done around block oil returns or cam cover baffles?

Only oil mods are a tomei baffle in the stock sump and cam cover baffles and a catch can that vents to atmosphere. Everything else is stock cause it’s still a stock unopened r33 engine 

yeah that's exactly why I was wondering.

stock pump and not happening under sustained high revs means it is unlikely to be a "too much oil in the head" issue, just a "oil shifting in the sump under high g" issue....it obviously goes ok :) overfilling should be fine until you have a reason to open the engine

That’s what I’ll be doing, yes it goes very alright lol. Once i put it on high boost and gave it a boot in second I had to start grabbing lock to make sure it didn’t hit a gutter or tree or fence.

need to find some rear end grip or make the 4wd keep up with the car or both :/ 

Have you binned the Hicraps system yet? Like properly bin it with a full kit where you remove the Hicraps ball joints.

That made a massive difference, and also dialling in the traction rods.

    • 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.
