clarkie 1 Posted January 20, 2008 Report Share Posted January 20, 2008 hello chaps. im goin to be rebuilding my gearbox very soon with a peloquins lsd and i want to change the final drive to give me a better acceleration but also want to change the 5th gear to give me a good motorway cruising gear so was thinking of using the diesel 5th. what sort of power will it be able to handle as im goin to be running quite high bhp. also if any 1 could give me part numbers for the bits im goin to need that would be a great help. many thanks . stu Link to post Share on other sites
Lizard Racing 0 Posted January 20, 2008 Report Share Posted January 20, 2008 Stu parts for the gears are 02A311361M and 02A311158R giving you 0.717 5th. Ive got a 3.94 final drive but most people opt for the 3.64. I have not fitted mine yet but I reckon I will only get 110ish in 4th and will be lucky to hit 60 in 2nd at 7100-7200 RPM ish. The 0.717 will give you same top and cruise revs as your standard 5th and 3.389 that you are running at the moment. Link to post Share on other sites
clarkie 1 Posted January 20, 2008 Author Report Share Posted January 20, 2008 thanks alex. what sort of top speed do you think it will do with the diesel 5th? Link to post Share on other sites
Lizard Racing 0 Posted January 20, 2008 Report Share Posted January 20, 2008 168ish give or take. I will try and find out when I go to Brunters thats if I dont bottle it! Link to post Share on other sites
clarkie 1 Posted January 20, 2008 Author Report Share Posted January 20, 2008 cool nice 1 mate. i think i will prob go for the 3.64 final drive. thanks mate. Link to post Share on other sites
Lizard Racing 0 Posted January 20, 2008 Report Share Posted January 20, 2008 with a 3.64 it will be taller 180ish on paper but you will need alot power and I mean alot to get over 150-160ish in a VR. You will feel a massive drop in pace when changing from 4th to 5th though. Link to post Share on other sites
clarkie 1 Posted January 20, 2008 Author Report Share Posted January 20, 2008 hopfully i will have alot of power so that should be a good option to take. any idea what the part number for the final drive is? (3.64) thanks Link to post Share on other sites
Lizard Racing 0 Posted January 20, 2008 Report Share Posted January 20, 2008 02A409143L is the part number but to buy new is £250ish. There is a MK3 GTI box for sale on Ed38 forum for £25 though! Link to post Share on other sites

john555 0 Posted March 19, 2008 Report Share Posted March 19, 2008 can you fit the 5th gear from the diesil without changing the final drive and what is the advantage of changing the final drivealso if i just changed the 5th gear what would it rev at at motorway speeds Link to post Share on other sites
Lizard Racing 0 Posted March 24, 2008 Report Share Posted March 24, 2008 Yes you can fit just the 5th GEARS. You can do it in less than 2 hours with the right tools and without taking the box out.Diesel 5th with standard FD will give you 70mph at just 2500RPM as opposed to 3000RPM ish standard.

james4287 1 Posted November 3, 2008 Report Share Posted November 3, 2008 possibly a daft question but will that then take forever to accelerate in 5th?will i be constanlty selecting 4th to ovetrake etc? Link to post Share on other sites
Lizard Racing 0 Posted November 3, 2008 Report Share Posted November 3, 2008 Thats where the extra ponies come in. Economy with standard engine is ok in 5th anyway so wouldn't bother. A diesel 5th will only offset the additional thirst of increased performance. Link to post Share on other sites
