motorrob 15 Posted September 15, 2017 Report Share Posted September 15, 2017 Currently running a 02m drp box. 4th gear has gone (weak point?) Taken 6th aswell running about 540 ftlb torque. What's my best option to do with box? Start upgrading certain parts if so how far do I go? I will be going for more power in the future. Any advise appreciated Link to post Share on other sites
ssaunders 199 Posted October 6, 2017 Report Share Posted October 6, 2017 (edited) Hi, how did you manage you manage that, the drp's are supposedly the best box? It's all about how much you want to spend? I have just had mine built with a quaife, solid input shaft, 4th gear support, 02q selector forks and diesel final drives cost £2k. I hope to run 550-600, if it was more I would look to shot peening and superfinishing and cryo treatment. I used Gas'n'gears in wales, known as HotGolf on the gti forum, top man! let me know how you get on s Edited October 6, 2017 by ssaunders Link to post Share on other sites
motorrob 15 Posted October 6, 2017 Author Report Share Posted October 6, 2017 I think it's the torque that's done it. Around 725 nm it's running. Looked into gearsets which say they good for about 600 :/. Will be going for big power/torque next year aswell.I have a spare box which I'm throwing in. Then the broken one will be done up to a higher standard. I did speak to this guy. Very helpful. Link to post Share on other sites
Flylow 2 Posted October 7, 2017 Report Share Posted October 7, 2017 Hi motorrob are you running boost and are you tracking the car or just Street use? Link to post Share on other sites

Sounds like the torque bent the shaft so the 4th gear came away a bit and stripped the gear, I read somewhere that it can take 10 ton before it bends with a solid insert it will take 30! i had a quaiffe gear set before and when I spoke to them the the gears are no stronger than standard, that was the semi cut one not the straight though. Bloody noisy as well! good luck. s Link to post Share on other sites
motorrob 15 Posted October 8, 2017 Author Report Share Posted October 8, 2017 Yeah running boost. Only about a bar atm. Street and dragstrip. (Not a daily anymore) Ah right that's good to know. I suppose with a gearset can always change gear ratios. They can be expensive though. did you use yours for street use? Unbearable noise? Link to post Share on other sites
ssaunders 199 Posted October 9, 2017 Report Share Posted October 9, 2017 Not for long journeys unless the stereo is loud. They whine like a touring car. I went with diesel final drives in mine, 1st 35, 2nd 74, 3rd 110 etc, on paper will top out at over 200mph in 6th! Link to post Share on other sites
