Hi guys,

Put this post up in general maintenance section and no replies as yet so I thought I'd ask some fellow sandgropers

I have just upgraded from a 33 GTST to a GTR and need to know how to adjust the grab point of the clutch as it is almost at the top of the clutch pedal throw

I did this on my GTST but this looks totally different

Can someone help as I have never worked on a GTR before

Cheers

Should be the same on a GTST, Just "unlock" the 14mm nut and adjust the rod accordingly?

LOL " Should be the same " GTR run a clutch booster and is not wise to adjust the rod , adjusting the pedal will just screw things over . Let the people who know offer the advice ..

The "same" in the sense they run the same type of rod/adjustment system regardless of having a booster or not.

In regards to the adjustment anyone who has fitted an after market clutch (say a twin plate) would have adjusted this rod to get the correct pedal adjustment. Just be carefull when adjusting. You always need about 2-3mm freeplay.

No free play will lead to excessive clutch wear, and too much will lead to a high grab point.

Oh an working on vehicles 5 days a week for almost 7 years, I think I have the "know" to give out this kind of advice :)

So you adjust the pedal side of a boosted clutch and nothing else ?

I tried but failed in adjusting clutch

On my GTST there is a 12mm lock nut and a post to screw in/out

On the GTR the setup is the same but the post is covered by a rubber grommet all the way from the locknut to the firewall.

I tried to pull the grommet back but it doesn't look like it should be messed with.

There is also a pedal adjustment that doesn't effect grab point just gives you a longer or shorter maximum throw of the pedal

HELP

Anyone ???

Does this mean there is no adjustment and my clutch is worn?

      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.
