Gearbox options

[Shakeywakey]

What are people doing with their boxes when running over 500?

I have an 8HP but decided against that as they’re lame.

Could do a CD09 swap but comes in about 4K for parts.

What other options are there for improving the FD box or fitting a better one

Cd00a is the route I’ll eventually take.

I’m at 850bhp and 510lbft, currently using stock box with OSG kit but having issues with jumping out of gear which is currently being investigated.

To do cd00a properly you are looking at least double that including new rear end set up etc. I’ve recently priced it up using Ronin rear end with 8.8 diff plus all the Fisch kit and other bits and pieces you need to complete install and that’s minus labour.

Ball park costs;

I’m only planning on running low to mid 500’s as it’s going to be a track car so hopefully I can get away with abit of a cheaper option.

I think when you’re getting to that price point I’d just go Samsonas 6 speed dog box in it.

Cars got a Studded full bridge with a GT4094 currently and was running big power, but I’m planning on simplifying the car with a smaller turbo and trying to make it somewhat reliable.

I’m at 505fhp and the stock box cannot take it. On its 2nd gearbox with the first being rebuilt twice and the second box now needs 5th gear synchro. I was looking at the cd09 but not looking to spend £7-10k on gearbox swaps.

I hear you but I don’t want a dog box for road car.

I was looking at Samsonas too and even with that swap you are looking at £12k.

HGT sequential is about £15k landed plus labour.

Grannas Magnum swap is £12k plus labour.

Quaiffe have a few options - again £10k range.

Unfortunately there isn’t a cheap swap out there really. CD00a/9 is probably the most cost efficient. The good thing about this swap though is once done IF you broke the box you can get brand new OEM ones for about £2k, the others all need maintenance and cost a lot more if shit goes wrong.

I’ve spent a long time researching various options.

Interesting - must be the difference in how people drive as I was running stock box at 670hp and it was perfect, it was even coping with 3rd gear 10,500rpm pulls, I’m sure I would of had issues eventually but I actually regret swapping it for this OSG kit.

I think the CD09 can be done for around4k plus labour which isn’t too bad but they don’t shift that great from what Iv heard.

I think the Samsonas H pattern box is around €5k to buy but seems abit involved to get it working.

Is your OS box broken? Would you be selling it once removed as that could be an option for me as I’d be running a lot less power than you
