Time for an update! I pulled out my brake pads after last trackday, and saw that they were pretty much toast. Blistered up, chunks coming out, and starting to come away from the backing plate. These

And then all these bits came along to make it look a bit more complete. They're from JSAI Aero, and seem to be of decent quality, and test fitted ok. Finally, a bit of a sneak peak Still hav

Thanks mate!

No specific plans to be honest. Just a few things I'd like to do.

So, after the trackday I went over everything again. Found my gearbox was making a nasty input bearing noise, so took it down to award. After a chat to Terry, he said it was nothing to worry about, and that the noise would probably drive out in a few hundred kms on the road. I suspect the ATF I was using in the box was too thin and not providing enough protection in high G areas, so I refilled it with Redline Shockproof light. Again, I can't complement the gearbox enough. People say they are weak, but this has had so many track days now, and looking back on the vids, a couple of times where it should have gone pop but hasn't! Driving style has a lot to do with it I think.

I've installed a power steering cooler, as I think the PS was getting pretty hot. I grabbed a small PWR auto tranny core from repco and plumbed it in, and ran a duct to it. Pics will be below. Pretty easy to setup, and not very expensive. It's just mounting it and finding the space!

I've got to get the dump pipe off, and it's got a couple of small cracks on one of the supports, they need a bit of weld.

I want to investigate water cooling for the wastegate. It has a tial 44mm on it, with the ports to water cool it. I want to do this mainly for reliability. But I'm not quite sure where to get and return the feeds to.

I also want to make up some deflectors for the front brakes, as they were getting pretty damm hot and glazed the pads. I never lost brakes, but it is clear that they can work better then what they were.

Finally, I might have my hands on some more slicks to try out after the Sydney 500. Should be a set of Yokos I can get my hands on. The Michelins have been epic, and are the Rolls Royce of slicks, but they are getting pretty worn now (have a look at the front right!).

You'll shit in an 11 if you can get it off the line.

Probably, my best 60ft was a 2.0

It's a bit of a pig to get off the line. This is on federal RSR 235/45/17 at 25psi. Doubt I'll take it again, I just don't want to smash the gearbox.

That brake squeal though

Because Racecar! Actually, I was bedding brakes in down the slow down area :D

Trackday put on by RTDC at SMSP south circuit. Had unfinished business since I was unable to take my place at the 2014 SAU trackday.

Had a little hiccup where some silicone intercooler pipe decided to burst due to heat and pressure, but fortunately some guys at the track helped me out with leads, and after a short drive, it was back in business without missing a session. Will make up some heat shielding to protect it for the future.

Rear tyres turned out to be pretty diabolical, so I couldn't even get full boost into her. Definitely due a new old set of slicks. In comparison, on full power out of the hairpin on the Brabham circuit day I could get power down pretty easily. On low boost it just burst into wheelspin.

Nevertheless, I got a PB (by 3.5 seconds no less!) of 1:04.1. Have no doubt on some fresher tyres that would drop into the threes.

Well, long time since updates, so away we go!

I noticed the rear pads were getting pretty hot, so I did something I should have done a long time ago. Cut the stone guards off it. I know, exciting right!

On to better shit.

I wanted to get it looking a bit tougher, and I went through a phase of looking for Type X bits for ages, but never bothered getting anything. I liked the look (everyone does compared to the earlier front end!!) and it gives me heaps more air to play with for ducting. Well, I found a OEM front bar, AND an OEM Lower lip for sale round my neck of the woods. Went for a drive, cash changed hands and boom; it was mine :)

Needed a bit of work, had some random holes in it, bit of a ding, and was silver, but had all the metal to go behind it. Well, something to work on!

So, I went to work - fibreglassed the holes, and a crack in the lower lip. Bogged up the dent, and filled the holes,

More to come in a bit :)

So being an hugely experienced painter (having painted two bars, and a roof in my life...) I decided to do me own work. DIY mechanical is one thing, paint and panel is totally another!

Anyway, Bar and lip went into primer just fine

Still have a fair bit more paint work to do, so another couple of weekends probably before its time to roll.

Got to get the electronics sorted for the new indicators too. The LEDs need resistors, and the wiring needs a tidy up.

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

      From Japan and back to Europe, my sh*tbox R34 GTT

      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.
