VR6 Turbo gearbox

Hi All..

Now i have my VRT up and running.. i need to concentrate on the gearbox..

I'll be getting an uprated clutch and diff but is there any other gearboxes with taller gears that i could use?

or do i take a tdi box and swap the internals? if so what box would be a straight swap?

Im running a GT35 turbo and it runs out of revs with so much more to give in that gear..

All help be appreciated..

Thanks

 

rubjonny can always rely on you for helpful info.. Thanks Buddy..

Any recommendations on a box to chose from? i'm currently running 400bhp but will be around 450bhp in the next year so need to plan ahead really as i only want to do it once..

I would like a final drive i think of 3.0-3.1 in 5th which should give me a good motorway cruising rpm at 70mph off boost.. the other gears i am not really sure about, as you can tell not very clued up about ratios etc

 

i'm thinking of that list maybe a asd would give me the best.. as it is very similar to the vr box but with a longer 5th gear..

 

yeah in my 20vt i had a diesel box.. can not remember for the life of me which code it was but it worked very well and performed just right.. but that was only 300bhp..

Thanks for all the info tho mate..

 

They are crap at multiplying axle torque. Driven them in cars with 400bhp. Kills the fun.

 

I have a 315bhp/300lbft car. I run the regular a 3.68 FDR and no diff. Wheelspin will only occur, if I provoke the car. Some of the trackday guys run 3.68 and 3.94 in their boosted cars with no traction issues.

On a VR6, just leave the 3.39 FDR, With 205 50 15 tyres, 7000rpm is near 160mph on those.

I would only use a 3.125 FDR if you are drag racing the car and want to manage gearshifts during a 1/4 mile run. Road car not necessary.

 

thank you for the reply..

it does 160mph at the moment.. and than the engine has so much more to give but the gearbox lets out at 160 so would like a 5th ideally capable of more, one of the main reasons really..

i know that may not be for everyone but its something i would like to change..

 

The 5th on those are 0.83:1. So in theory something towards a 0.75:1 will increase the mph/rpm ratio.

 

perfect will see what i can find... Thanks mate

 

Wee tag for me

 

How is the search going?

 

hey buddy..

i think i am gonna go for the ASD code 5th gear which is a 0.717 which should give me what i'm looking for.. would have been so much easier if i could of just put a tdi box on it but wont happen being a 4cyl box

 

What about the V5 box from the 2.3 Mk4 Golf/Bora?

 

Same gear spacing as a VR6 12v CCM gearbox, but with a 3.94 final drive, so pretty short if used with 195/205 50 R15 wheels and tyres.

 

just as an update.. ended up buying a 0.717 5th gear which will have installed by next week once i get a chance to have the box out.. which fingers crossed will give me what i was looking for..

 

I do have an uprated clutch, pressure plate and flywheel if still looking.

 

sorry i had to laugh at this - as if 160mph is not enough in a 20 year old VW!!

 

Quite a lot actually!
