Os88 Vs Hollinger Decision!

Okay so after lots of research and with some mixed reviews I'm after some info on people's experience with the OS88. I'm helping a mate with this as he's stuck with the transmission. So he's building a big HP GTR, we're talking Nitto RB32 Stroker, CNC head with the works, dry sump, ProMod etc etc. Hoping for 8 sec passes one day.

Now he's always wanted a sequential box and is trying to stay away from auto like the popular TH400 etc even tho it's proving to be difficult to decide. From what we've found is that people who used it in England and on their forums it's a mixed bag of reviews some say it's shit, many have broken them etc. Some say they're the shit. Some say that Hollinger is better but Hollinger can't take too many hard launches but is more reliable and less maintenance. Also apparently OS88 is a pain in the street compared to the Hollinger and that it'll wear out quicker requiring attention.

As you all know none of these are cheap and even tho he's willing to spend on whatever is better but it's proving to be a hard decisions. With the cost of any of these it's important to make the right choice, which is why I'm asking for some help on here.

If anyone has personally used them as dailies and track warriors, could you please help us out and shed some light.

To make it harder, PPG have a sequential soon and Albins seems to be gaining popularity.

Yeh I know that's the only issue, how long did they really last. Even a Hollinger will do 8's easy but won't take too many launches before issues. I'm starting to think the TH400 is the way to go, app

Having purchased and installed an OS88 last year, it really isn't that crazy out on the street.

I chose the 88 for a few reasons.

Helical cut gears. It's no noiser in gear than a stock box.

It bolts pretty much straight in (apart from a bees dick of tunnel massage)

From what I can gather, the Holinger is a lot more "crash and bangy" than the OS88.

Cost. It was quite a fair whack cheaper than the other options.

The PPG sequential I'm no sold on. Speaking to them for a fair amount of time while making the decision on my box, they said "we still use a stock housing... There is only so strong we can make it while being restricted here" . The OS88 for exmaple moves the shafts further out, making the gears larger.

I chose the R3C (triple plate solid centre) and it's absolutely fantastic to drive. I doubt it would hold the power that you're after. (Although the Tomei Yellow R34 drag car used an R3C so it can't be that shit)

Yeh Ppg he's not very keen on, not too much info on their sequential, basically it's still unproven.

Thank Paul that's exactly the type of response I was looking for. I'm a massive OS88 fan and that'd be my choice but then again I wouldn't be chasing these crazy numbers which is a different ball game. I'll pass on what you said.

Jap's were doing 8's back in late 90's in sequential boxes. dont know how long they lasted but I would go with the th400... just because I didn't do it and want to know how it would feel street driven daily.

I'm starting to think the TH400 is the way to go, apparently very easy to drive on the street too. Only thing tho. An auto GTR, I can't make peace with that and I respect that it works incredibly well but I couldn't do it. That's me personally, but he'll have to make a decisions

Talk with mercury motorsports how much abuse the OS88 took at over 1000hp. Unbelievable gearbox!!

Yep speak to Adam and Humzza at JEM they put one in a red 33 GTR I believe and Humzza had one in his car.

Give them a call and just say you're looking for advice/experience - Could even find them on Facebook if that helps

They were also doing them with H-Pattern boxes lol.

You've also got another choice - Samsonas. Quite a few WTAC cars this year were running them, I suspect they are part sponsoring a few cars to get the name out there - logical business sense.

So not sure how good or not good they are, certainly something to look into given local support etc.

Albins also have been doing good work and releasing various upgrades to lots of boxes lately, which is interesting.

Thanks guys we'll give Mercury and JEM a buzz and see what they say. We'll also contact Albins and see what they say. Who would have thought this was gonna be this hard lol.

Ash Samsona's is good but I don't think they've released a GTR version and from the sound of it they're good to about 800hp. But we'll suss them out also.

I bought one with Paul for my 34, I have an R4C quad plate and I have both street driven and raced with the OS88 and am quite impressed with it, I was looking at the Albins after driving my brothers offroad race car with an Albins sequiential but they run a massive shifter assembly which can't be hidden for a street car, for a street car the OS88 wins due to its stealth but for a out an out race car the manualised TH400 would be my choice

I had a Hollinger it was great but there service was rubbish minimum of a 3 week wait for anything.I had no dramas but I didn't do a lot of work did some street driving maybe 20-30 passes at the track and I did a trackday

I have now upgraded to the albins  I'm extremely happy with the albins there service is amazing I had 1 issue and the part was flown up from Victoria and car was on the track  the next day. The gearbox has not missed a beat has been in my race car making 530kw atw and I have put it in my street car which has been up to 1044hp atw

but the down fall is the tunnel has to be modded literally a section cut out and fabbed new one to be installed

I'm hearing good things about Albins, but the trans tunnel mod sounds not cool... what model car are you running it in?

For those interested in an OS88, here is the oiling issue that needs to be rectified before you put it in the car. 

The little slot where the light is coming through is the breather for the box. There is no cover for it and the gear acts like a paddle wheel and pumps oil up the hole and through the hose. So a cover will be made to stop this.

The oil breather fitting also needs to be drilled and tapped. My fitting popped out once it got in the car. OS must use clag glue to secure the fitting... it doesn't last.

I am also changing the sensor that lives in the bell housing.

So the OS88 - are they all helical cut gears?  I love the noise of my dog gears - will I lose that with a OS88?

Where are OS88 made - japan?

Having issues replacing the reverse gears in my Quaiffe/Trust 6 speed sequential - so may have to look at a replacement.

Quaiffe have the reverse idler gear and cam selector operating arm - BUT - No selectors or reverse gears.  Will have to be made I'm told - and that could be many months away i'm told.

Quaiffe haven't been the quickest in responding / helping either.  

I'm shattered - I love this box - would love to fix it - but proving difficult it appears.

Been busted up over it for the last day .....

      What do you mean?  In between the two I shared?  They're the same boost   This will be insane.   A mate has a GTSt with a 9:1 RB30/25 with Tomei 256 cams and a Borg S362SX-E that is already a beast from the basement but has a stock 5 speed and will probably get a ZF8 one day.  After the G35 900 RB26 setup I'd be lying if the topic of "Wtf would a divided G35 be like on this thing?" idea hadn't come up - you'd definitely want a wide boost control range setup with it, as even with the less responsive and potent S361 we're having to ramp boost in from very low levels in the early gears.

      Upgrade an rb25neo

      ZF8 is faster, wider ratio spread, better in every way. I do not dispute this. But I have brain damage and I want the feeling of shifting gears. To me the extra work is fun, but I daily an automatic and in the US like 90+% of cars are automatic so a manual transmission is an "exotic" experience. If I want an automatic I've driven an F80 M3 with DCT more than a few times and it's incredibly capable but it's emotionally vacant to me.

      Different folks for different folks I guess - for me, the 6MT > ZF8 claim is wild.  If I had a manual Skyline I'd be saving up fix that with a ZF8.  I went for a M135i, has the N55 which resolves a lot of the issues the N54 has, it already has the ZF8, is barely heavier than an R34 GTt, full boost before 2000rpm while also being real-word-faster than my old 280kw @ hubs R33 GTS25t and doing absolutely everything better.  There's nothing I'd change on it to be more like my old Skyline, tbh... it doesn't sound the same but it's got it's own awesome sound - definitely not worse.   To be fair I can't argue with most of those points.  I guess i was pointing it out as a comparison for a Skyline GTR and it's much closer all around there, like the weight difference between an M240i and an R34 GT-R isn't that much etc.   As above, I ended up getting an M135i which is in the 1400kg range - the M140 and M240is that you can get up till 2018 are B58, ZF8, RWD and in the 1400kg range which is a bit of fun... but doesn't fit the tyre etc of the Supra.  They are a run drive, though- maybe no an A90 Supra but a huge upgrade over a Skyline "sporty chassis" wise.

      Im loving this thread. I have a g35/900 t4 split 1.00 ar going on my rb30/25 with 9:1 and 264 cams. its drive by wire and with vct i think it should spool nicely. I have the 8speed gearbox on the floor ready to go on so full boost changes will be a thing if the tyres can deal with it. it should always be on boost

      The trouble for me is the automatic takes away so much from it. And the E92 has hydraulic power steering. Even after putting in an LSD you're looking at re-mapping the xDrive to be more like a Skyline which is just a lot of effort for something that is supposed to be easier and cheaper. I consider the E92 335i 6MT to basically be the obviously superior car to something like an R34 GTT. Half the price out here, the N54 makes so much more power so easily, is a far more refined car, etc. You do have to deal with the nightmare of the N54's foibles vs the B58 which is comparatively miles better and if a turbo does fail it's only one of them vs two and a lot less pipe spaghetti.  996 or 997 Turbo has the AWD system mapped like a Skyline. Basically always RWD unless engaging the front axle makes sense. A coworker let me drive his 997.2 Turbo 6MT and it's absolutely tremendous. I don't think I'd want more power in a street car.
