Hi all,

Having pretty much destroyed my gearbox, im in the market for a strong replacement.

We all know OS gearsets are good for the money but im leaning towards a DOG engagement gearbox.

With PPG the leader in the market for these there is another option with PAR.

Just wondering is there anyone out there who has one of PARs gearsets with dog engagement?

Comments?

Don't think its been used yet, but Anna just bought a par dog box for her 33, and Mark and I are going to go that way for the 32 (straight cut as well).

There was a thread recently discussing some opinions, Brad in particular has used a wide range of them including par, ppg and holinger

Ive chosen to go with a PPG Helical 1st-4th DOG (Syncho 5th)

Now all i need is to find someone that sells them at a decent price.

Anyone have any suggestions or know someone who has an account with a supplier that could do me a good deal?

Dont buy a helical PPG box. You will break it.

Straight cut or nothing when it comes to dog engagements.

Been there done that with pretty much all of them. PPG is far better than most though

The ONLY one id now recommend is the H pattern Hollinger which is what I suspect is in my car now but not certain. Buy the H6S its pretty much the same box as my H6S-SEQ but a H pattern

You'll need a bellhouse ing its the only bomb proof box I would trust. I know of some second hands ones coming up for sale if your interested. Pretty well priced too.

We have a PPG helical dog in our street/circuit GTR and its a bit of a bitch on the street...very clunky and you really have to smash it into gear. We have not had any problems with it though and its done about 12000klms, been thrashed a fair bit and done Superlap. The straight cut in the drag car is so much nicer to shift and can be upshifted effortlessly using only 2 fingers. The whine in 5th is annoying though and makes highway cruising in Twoogle a bit unpleasant.

Hmm interesting.

With the amount of punishment my standard box has taken i cant believe the gear teeth are still attached.

1st,2nd and even 3rd gear launches and still no breakage (excluding syncros)

Which is why im thinking the PPG helical cut "has" to be far far stronger.

The noise of a straight cut would get on my nerves after a while especially on cruises.

Brad, the gearsets that you might have for sale, are they all needing a new bellhousing?

I think if Brad cannot come up with something Dave the PPG helical would be the best option then. The straight cut is a fairly noisy box, where as the helical is much quieter but harsher to shift. Come up and have a drive of the car if you like to see what you think.

I can come up with the hollingers within a decent time frame. Its a matter of the people I can buy them from getting them as well.

They are ex super car boxes which have been serviced and rebuilt. Ill ask whats available.

But yes it would need a bell housing attatched and a tail shaft made up.

Im not a fan of helical gears. They have pros and cons and im a performance situation there is a reason most good things are straight cut. But your right the noise does drive you insane.

The hollinger would work out more expensive than a PPG though. If your interested ill ask the question

I have a couple of friends running the PPG helical dog's in their GT-R's, both of which make just over 800hp and they have not smashed them. They have not done mega km's but when they come out they get absolutely punished. Launched every time, 3rd gear burnouts.

Looking at my OS Giken and PPG gear sets side by side and going off the tooth profile, if TWO-06L didn't smash his OS Box, and you haven't smashed your standard one, then there is NO WAY that you'll smash a PPG Helical cut unless it falls off the delivery truck!

Dave drives the street/circuit car like a demon...with over 600hp at all 4...still going strong.

      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.
