Have an OS Giken 1 - 5 box i bought off mayhem last year, just before Powercruise (October 2011). It was in the car approx 3 weeks before i busted it at Powercruise, driving like a numpty.

It's been sitting in my shed since as i went back to a standard box for the interim while i repaired the OS box, but the standard one has held up fine for 12 months & i have no incling to fix the one in my shed... So it's up for sale now. Suspected broken Lay Shaft, but i will confirm tonight once i crack it in half. If my suspitions are correct, it is an easy fix & the gears are all still good... It just doesn't currently have reverse or forward gears 1, 2, 3 & 5... Which is why i beleive it to be the shaft.

Wanting $1200 as is or $3k repaired. Open to offers though as i need some cash, so don't be scared to lowball.

Email/text/phonecall preferred as i wont be on here a whole lot in the near future.

Thought i'd update in here to save being asked the same questions over & over again...

I am in Perth, WA. Freight is not an issue provided you pay for it.

I got the box open to a point where i could see a few of the cogs & all seemed sweet. Couldn't pull the bellhousing any further forward that approx 1.5 inches due to something holding it back & my peanut sized brain not being able to work out exactly what. When i spin the input shaft it will spin freely for say 2 revolutions, then bind up & turn the gears slightly before spinning freely again. This confirms in my mind that it is a shaft that has sheered & when the pieces re-connect, it turns everything slightly before 'letting go' again.

I have 6 people all saying they definitely want it pending what i find when i finally manage to get it open fully. 3 of them are willing to pay my asking price (which is extremely generous), so i recant my statement above about "lowballers welcome" for now.

I will do my best to crack it completely early this week, but i have quite a lot on & can't commit to anything at this stage.

Soooooo, anyone care to share some info on how exactly to seperate the bellhousing completely? I have taken off the nosecone piece that houses the bearings & slides over the input shaft, taken off 3 x circlips (2 from around bearing case that sits on input shaft, 1 from the little shaft that pertrudes through bellhousing on top left), i have undone all bolts that connect bellhousing to box body (12 in total from memory) & i am now stuck with a 1.5" gap between bellhousing/box. Is there more than 3 circlips & i am missing one? Is there a secret nut/locking mechanism somewhere i am failing to recognise?? Am i not using a big enough hammer??? Haha

Cheers all.

    • Kinda glad I never got to this ..    https://www.facebook.com/groups/1483859159195077
    • @GTSBoy This method was able to get readings of -10 to -2, so it looks like its monitoring.  Now I need to figure out why the vacuum on the line provided isn't alternating with manifold pressure.  I went with 2 lines that an RB25 tuner recommended but I'll get a longer hose and try directly off the back of the manifold.  He may have been used to OEM intake setups while I have a DBW setup that removed the MAF and IACV.  
    • I work at a car detailing and tinting shop called Quark which gets all manner of German cars in usually (mainly due to a contract with Mercedes Benz Kita Osaka, BMW Nishinomiya and others) but every once in a while something special comes in, like a fully restored 1972 HS30 Nissan Fairlady 240ZG... The shop owner had immediately started applying film to the windows as soon as it was in the shop so the interior was completely covered in towels and plastic sheets. But I could get a few photos of the engine bay which was restored like new. Such an amazing car to see in pristine condition in Japan these days.  
    • Was going to say the car pulls up nicely everywhere, especially going into that last long right hander before the main straight. Looks like a lot of fun.
    • Hey Dave, welcome aboard! Good to see another soon-to-be Stagea owner here. The wagons are awesome — plenty of space, still got that Skyline DNA, and loads of potential if you’re into mods. Definitely post up pics when you get it, everyone here loves seeing new builds. What model/year are you looking at?
