hi mate,
Its just the straight cut gearset and dog components that PPG provide (1st - 4th gear only) for the dog box. Youre looking at about £2000-3000 for the gearset only depending on how well you barter with PPG
If you were thinking of dropping one into an R you would also want/need to consider:
- Gearbox casing
- Rings/Other Ancilleries - Nissan OE stuff is good enough in my opinion
- Selector forks etc - PPG do a replacement 3/4 selector fork for about £400 and you really want to use this
- 5th Gear - I'm going (as I think Rishi is) for a Helical cut 5th from Quaife.
- Case treatment - If you're going for a dog box, Im assuming you're probably running or plan to run more than 400 bhp. The GTIR has a gearbox casing which is weak and has been known to split/crack/explode - while straight cut gears do a lot to help workaround this problem, you will still have it. Im personally going for De-seaming, Shotpeening, Bracing and then Cryo treating mine to try to get the strongest case possible.
In terms of gearing, I posted the figures a while ago (the topic was Holinger Sequential Gearbox), cant find my email otherwise Id post them here for you
Hope that helps, Cheers Andy

Still waiting on some shims!
Just think about drivability too... You can take the car back to Hiteq and ask Ian for his Bracing Mod... Or similarly ask 00sid for his... Both 00sid and Mo Jamal ran at TOTB using their bracings, and both drove home after a hard day on the track and drag strip without any problems...
Remember that its not the gearkit thats the problem... Its the thrust load on the casing caused by the Quaife's helical cut gears... Hence where the bracing comes in...
There is of course the PPG Straight Cut Syncro box which would allow for normal driving and remove thrust load... You'll just have more of a whine from the straight cut gears...
The full blown PPG Dog Box will be a pain for normal driving... But perfect for fast road, track and drag...

i have been checking with japanese Tuner about this WPC treatment on GTiR gearbox
was quoted around 600 pound plus shipping back for me
been informed that RNN14 gearbox commonly break at 400bhp level
a WPC treatment will make the gearbox stronger
a lot of RNN14 using this method with OS Giken Twin plate and still can survive for hard abuse
that what i was told

What's the price for the bracing from Hiteq or 00sid? I'm interested in it myself for casing piece of mind.
Looking at them I'm assuming they can be fitted in situ, is that correct?

si originally said he'd do them for £150 i think
