Is that a definately that the gearbox can handle 310 BHP and 420 NM? Or did you mean the car itself. I Think I expressed myself badly in the first post. Because I was refering to the gearbox.
It should be fine at that power. Just dont drive hard in first!! You will destroy the input shaft bearing. Been there done that. Im on my second re-con box! But i am running higher output than you

Is their anyways that one can strengthen the first gear?
When i floor it in first it never reaches full boost, just around 0.9 bar ... But it was not my first gear that died but the 4th So i guess i will just have my gearbox repaired....
Nothing can be done with the gearbox to make it stronger without having special casings made and larger bearings put in. Sounds like the syncro went in your box. Thats very common on the 5 speed box, my first box lost 2nd and 3rd gear syncros.
Mine makes about 1.4-1.5 bar in first so i have to take it carefully.

to parking ticket, a speeding ticket, a broken 4th gear, then my x-garage called and say that could swap the gearbox for 3000 euro (a new one)... Well kinda say bay bay to them and found a repair service that would repair the gearbox for 500 Euro...
But in your ECU its has tables that it uses to decide how much boost fuel etc that you can have.
in 1st, 2nd gear etc its not putting lots of load on the engine so it refers to that part of the ECU map. Normally this doesnt use huge amoutns of boost.
as more loads is put on engine, e.g. flooring throttle in 4th doing 4mph will have a higher loading on engine because of the gearing of 4th gear. In this situation the ECU recognises this and will give more boost.

:eek2: :eek2: :eek2:
I hope you ment 40mph, cause a by-product of higher gears at
low speeds is carbon build up on cylinder heads and valves.ops:
Not an easything to get rid off and valves might not shut properly:mad:
6 speed box is stronger than 5 speed, 6 speed is based on original 016 5 speed unit used in type 85 inc. ur quattro, type 44 inc. all 200 turbos and pre '88 100 quattros. The 016 box in my type 85 Coupe quattro took a lot of abuse with 3B 2.5L. This was 426PS and 411.3 lbs/ft. Although I am using a matching 6 speed box with my RS4 engine, I do wonder if I wouldn't be better off using the good old 016 5 speed - problem is the bellhousing doesn't have enough holes to accommodate the Biturbo V6 engine... If you have access to a 6 speed unit, use it, or even better, an 016 unit if you're not bothered about losing your torsen centre diff.

What do you mean by loosing my centre diff? Will it fit perfectly or what?
