Lets talk gearboxes

[Stuwey]

In reality, you can only make a shopping-trolley hatchback so fast.

Turbo is a good start, a K04 or Frankenturbo or similar is better. Front mount 'coolers and free-flowing exhausts are good, too. Some quality suspension and some decent bushings to control the chassis is certainly getting things going better, along with some larger brakes to make it stop again.

However, you can only go so fast with a silly open differential, especially with the added handicap of FWD.

I ask, Where to with this?

We know the crown wheels can be different on any day of the week, so it's a gearbox out and measure, even before ordering the diff for our standard gearbox (which i'm not confident in anyways)

We also know, with some out-the-box thinking from our UK friends, that you can get 6 gears under the bonnet, but I ask... Which box? Is there any preferences of those available, or any particular car we should be thieving these from? For those with and LSD fitted, which would you choose again?

Essentially i'm thinking 6spd and LSD into my car in the future, but want to figure out exactly how I might go about it, BEFORE i get my hands (probably very) dirty.

^ speeder from the mk5 2 litre FSI is what Junior fitted to his Polo.

Not supposed to be really strong though. It handled 320 hp out of his car ok though.

I wanted to be the first 6 speeder down under

I can get you an 02S over if you want Gav

This'll be a while off, you may still take that crown yet.

GF has a 2.0/6spd in her FSI Jetta - It pulls more revs down the highway than my car - hence what had me thinking...

[nightphotographer]

That's probably an 02S code? MK5 FSI...

Junior runs and 02M 6 speed IIRC

Pretty sure (at some stage) boba's 1000hp golf runs/ran an 02M as well

I reckon it is 02S Lee, the 02M is physically much bigger with different mountings from the pictures I looked at. Though it has the internal slave cylinder like the 02M.

Yeah you're right he was running the 02S
UK Polo GTI 320BHP

Re the LSD, depends if it's being circuit driven, or just straight line. If circuit, you want a clutch plate style not a torsion. The people who I've spoken with how know the difference, all say the extra money of the plate LSD is worth every cent.

If the car is off the road, the the crown size is much less relevant unless you're ordering from overseas with months as the lead time.

In speaking with my wheel aligner guy who does the setup for race cars, he suggests a plate diff is worth 1-1.5secs on lakeside (2.4km circuit). Guy Harding advised a plate diff is around the $4k fitted. Big coin for 1 sec...

I'd probably put a Quaife ATB in, they drive nice without being intrusive on the street and would be a huge improvement on the current open-wheeler-peeler, even if not a total winner for the last tenth on the track.
