Nah man. Was ordered two months ago. I'm betting late February if delivery in Japan works well with the container it's being put in.

They both have taller ratios.

Assuming a 265/35x18 tyre and stock ratios and a rev limit of 8000 RPM the speeds are as follow

Stock

1st - 75

2nd - 120

3rd - 180

PPG Helical and straight cut dog

1st - 89

2nd - 143

3rd - 189

OS GIKEN

1st - 87

2nd - 138

3rd - 190

Is the os giken speeds that you have showed are they the correct speeds even with the close ratio gear set? I would have thought that the closer gear set would shorten at least gears 2,3,4 and 5? Ow btw are those figures for a 34 ? Or 32 gtr?

The OS GIKEN 5 speed is most definately taller than factory gearing. That is assuming 4.11's in the diffs. Gts4 ratios will shorten that by 7% iirc.

What's the setup?

It would make the gearing awfully short with the 4.11's. You'd be changing gears like an Evo. It isn't the cheapest conversion to do.

Like he said what's the set up?

Set up is an r34 gtr getrag 6spd gearbox fitted to a 32 gtr .. it's the whole box including everything needed to do the conversation

By setup I meant what's the engine/turbo combination.

Boobee. The reason I was asking turbo/engine combo is that (and this is my opinion only) the taller gears in the OS set make a lethargic bottom end of a 2.6 L engine and make it even more pronounced.

For example, a mate on here on a pretty decent R33 GTR put one in and ended pulling it out and going back to stock ratios. That was predominately a track car too. 2.6 with -9's and -5's at different points.

Just something to think about.

Bakemono. Cheers man :D. Be good to drive it again lol.

Oh the lols

only do the Getrag if you do the 3.545 diffs as well, 1st gear in my 34 is now and always was useless even when it was a 2.6 with -7s, so add 4.11s to that and you may as well stay with the 5 speed as you won't use first with the Getrag

I can't wait to see the difference between 4.11s and 3.545s with the two identical OS88s once put side by side :D

    • A locally delivered Infiniti have remote start installed but don't come with the remote start key. You need a new remote start key and they just need it programed. And this is different to making/programing a new key that just starts the car.  
    • Cheers, and cheers for sharing so much of the build and also sharing the glimpse of what turns out to bring a lot of us poor decision makers together haha.  I do recommend learning more about how to manage it, if not considering getting a  formal diagnosis.  The discussion with the psychiatrist I got my diagnosis through was quite eye opening, things I'd not even considered to be ADHD related and hadn't mentioned were things she asked about out of the blue and were common themes with people with my flavour of ADHD.   It's not a label for people who are hyperactive and ill-attentive, there's more to it than that and some of it can be much more challenging or damaging - though there are of course two sides to the thing, and a lot of the stuff we have to go through and work on to live with it make us effectively "better" at other things as well. Aside from the fact that there is some argument I could have a bit of ASD seasoning in there (came up during the diagnosis, and neurodiverse things seem to not stay as a cookie cut) I suspect you need to learn more about ADHD if you are puzzled about how hyperfocus could possibly apply.  I *do* personally use "superpower" with quotes deliberately, but it's 100% an ADHD thing due to the exact reason that lack of focus is also an ADHD thing... Loosely speaking the inattentive side of ADHD isn't the inability to focus, it's the inability to control where the focus goes.  Not being able to sleep because brain is more interested in thinking about a stupid thing I said to a girl I liked 30 years ago, not being able to focus on work because my brain is more keen on putting together the torque management strategy we're going to try out with a drag car next weekend, not being able to focus on a conversation with someone I WANT to listen to and respect because there is a flickering light in my peripheral vision.    If I could just stop work and build the torque management setup right there and then I'd not hear anything else until it was done.  
    • Maybe you should do some more reading.  Google positive effects of ADHD and you'll get your answers.  One of my personal downsides of ADHD has been talking before I think.   Maybe you have it too?
    • Excuse me for butting in....but which part of ADHD can be considered a superpower? I would have though it far more likely that some ASD comorbidity is more likely to be contributing to an ability to hyperfocus on something. ADHD being aimed somewhat in the other direction. My shed looks like your shed. My whiteboard list of unfinished projects has entries going back 15 years. I know what you're talking about - I just struggle to connect ADHD to the results being discussed.
    • Thanks for reaching out!  It's a blessing and a curse at the same time.  I'm undiagnosed but it doesn't take a rocket scientist to see it in me... I have more half started projects laying around my house, shed, garden, etc taking up space and money, destroying aesthetics than if I added up all of my mates projects together. But, ADHD gives me the ability to hyper focus on things that no mere mortal could even  comprehend.  A recent pool build is an example of that....  I dont know anyone else that would be dumb enough and focused enough to take on then complete something of that magnitude. I call ADHD a superpower but it can equally be completely destructive if not controlled and focusedon the right places. Addiction is a major concern to ADHD people and thankfully my addictions have been no worse than projects, XBOX, chocolate and being an arsehole! It's often hereditary and my 13 year old son is currently learning how to drive it at the moment. Keep lurking! If i can finally finish this bloody thing at some point it will be a win for all of us ADHD'ers! 🤪
