Use what the manual recommends.

Higher octane rating doesn't mean more power, it means the fuel is more resistant to being ignited. So putting like 98ron fuel and octane booster into an old R31 is just going to make your car a son of a bitch to get started and missfire or something.

I wouldn't bother wasting money on BP Ultimate with a normal car just because it has detergent in it.

There is a reason BP98 is the most recommended pump fuel for high performance cars...

and ????????

if you state that then you should state the reason

any 98 is better for a high performance car .

Ultimate offers no gains over Vortex 98 and vica-versa

I beg to differ. Reasons have been pointed out in this thread already.

Not all 98 fuel is the same. It may have 98 octane, but that is just the RON, there is more to fuel than that. My mechanic owns the Glen Forrest Caltex service station, he is highly into cars and is the only mechanic i trust my car with. I asked him what fuel i should be filling up with and he told me BP Ultimate hands down. That coming from the owner of a Caltex. Now I'm not basing my argument on that fact but it does still weigh in.

I've driven with other fuels before. Vortex i don't notice a difference in performance but i don't get the same mileage out of it as i do with Ultimate. I've tested this numerous times, and be it absolutely hammering my car taking it up to redline or driving like a old woman, BP Ultimate comes out on top everytime, i get about 15-20% better efficiency with it. Peak 98 is shocking, i'll never use that again. Car drove like crap and i only got 210km's out of a full tank. I've never used Shell in my car, refuse to touch the stuff after it destroyed my dad's old car.

Point is, you ask anyone that knows anything about fuel and cars, their recommendation is BP Ultimate. Sure it may be similar to other cheap fuels, but cheap Chinese performance parts are very similar to Japanese performance parts... Rule of thumb with cars, you get what you pay for.

I used peak about a week ago and got 425kms, how the hell did you manage 210kms in a non-turbo.

Hence why i don't like Peak. Went straight back to 500kms to a tank when i filled up with BP again. I wasn't driving aggressively or anything either. May have been a bad bit of fuel, i have no idea, but i've never had a problem with BP. For me it is tried and trusted. I've done my own comparisons and BP stands out. I'd rather pay the extra 5c p/L, or whatever the difference is at the time, for the piece of mind that what i'm putting in my car is healthy.

Why do you change fuels for in forst place ??

I also prefer to pay a premium for consistency in quality.

Wont ever be consistent in pump fuels

    • 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
