2.0l conversion?

[BLN355]

Seeing as the Polo R and "rumoured" audi S1 will be running a 2.0l I was wondering what would really be involved in doing an engine swap on the Polo?
An s3/tt or golf r 2.0 would be a punchy unit in the 6r body (if traction wasn't an issue).

Im guessing custom mounts and a shed load of wiring would be the major hurdles?

You'd also need either a manual or a 6 speed wet-clutch DSG as well

And new suspension components to handle the extra weight hanging over the front axle and you would have to do a fair bit of weight reduction / weight distribution over the car otherwise all the weight will be at the front.

Another thing the 2.0L engines use 6 speed dsg's which i think are slightly bigger (because of the mulitplate wet clutches) and they also use different mounting positions.

Would be epic to see but a mammoth task to do. Would probably be easier getting a Polo R LHD model from Europe and put RHD dashboard and rack and pinion in...

Or just get a permit to drive a LHD vehicle

Would it be road legal? Or just a track car?

Obviously it can be done but Apart from all the conversion issues. finding the right suspension parts and the cost all aside Traction would be a issue if trying to push more power. In standard form the extra weight would compensate for getting down the extra power. If you then want to chase more power you will have dramas. The 2l can be modded to get a lot bigger numbers then the 1.4l TC and you just can't fit the wide wheels you need to handle the power under the polo unless you make the guards wider.

And at the end of the day the cost of doing it all legally would get you a golf with all the bells and whistle plus a lot of go fast/ handling mods

Yeah it'd be done to be road legal otherwise i'd just buy a clanger and go all out.

But where's the fun in a lightly modded Golf that every man and his dog own

2.0l conversion?

Won't work, the drivetrain geometry would be all wrong. The CAV engine had a fair bit of tweaking to get it to fit in the polo.

As pointed out, you need to run the 6 speed box in either dsg or manual. The weight penalty alone (hence the use of the dq200 dsg) is unfeasible.

Nice thought but if you want to chase that kind of power etc, I'd be first looking at stroking out the 1.4 first, if possible...

Now that would not be run of the mill. And if done properly would potentially solve the oil issue. Would need a whole new engine management system though as I don't think the current ECU could be tuned that much considering it needs bench tuning just for a simple remap. Wonder if there's a kit or maybe just shorter rods and different pistons?

[LunchboxVRS]

But now I said that the increase in torque may kill the gearbox if not upgraded as well.

2.0l conversion?

The ecu could be tuned easily enough and the dq200 with some software tweaking could quite happily handle more torque. The issue would be gettin someone to take the plunge first....

[LunchboxVRS]

Do we know how much torque it can handle especially when pushed? And down low? Stroking more often then not will produce a lot more torque compared to the power gain if you compare it to other mods. A friend and myself both had ford 5L v8 and he went down the bolt on vortex road where I went the stroke to 5.6l path. Peak power was within ten Kw of each other but my torque was nearly 140nm more then him and came in a lot lower in the rev range. I know there completely different but that's just an example of what stroking can do torque wise. A tune on its own will raise to 300nm then because your increasing bore the amount of air needs to be increased so a intake is needed. And with more air in you need more air out so that's an exhaust as well. Combine this with the torque increase of stroking I would estimate over 400nm. How long would a stock box with say just a DSG tune last with that much torque?

2.0l conversion?

Guy Harding would be the one to ask because after all, the apr polo is putting out in stage 2 guise some healthy torque figures. The issue isn't the gearbox, it's the clutch packs and the amount of slipping they can handle. To give you an idea, a tune 1.4tsi doesn't make peak torque until full clutch engagement has occurred, peak torque is ~3200rpm. The clutch will generally be generally slipping in the first 1500-2000rpm even without the supercharger engaged and if the supercharger is engaged then 250nm is getting fried through it (and they wonder why they have issues). The dsg tunes help to eliminate this ridiculous amount of clutch slip by being more intelligent with gear selection and shift points, as well as causing less slip. They don't suddenly drop into 2nd when you're requesting 50% throttle after a take off and then instead of dropping back, try to get the car moving in the wrong gear.

With a dsg tune 350nm should be quite workable. In all honesty though with that kind of grunt in a car that's 300+kgs lighter than a golf already should net some healthy performance increases.

rumour has it there is a Polo GTI with 310nm+ at the wheels...

well there are several:

Stage II GTI on dutch forum: 372nm and 233hp (done by JD engineering, the best VAG tuner we have so it can be said its still reliable)



Or conversions:

Polo 6R with Audi TT RS 2.0 TFSI, 272hp:



Or this one: Polo GTI fitted with a 170hp GTD engine from Golf 6:
