I just noticed a 2.0 TSI engine is an option on the Jetta whereas the vRS currently only has the 2.0 TFSI. The specs seem very similar when in the Jetta and vRS so can't see an obvious reason to prefer one over the other. Presumably the TFSI will be retired in due course and the TSI will be the only option.

Other than the published specs is there anything else compelling for the customer about the 2.0 TSI?

VRS now comes with TSI

just wondering if you know from what build week the change over is going to happen from being TFSI to TSI on a VRS or is it an option? instead of a complete changeover

its already happened..i have had mine for a month nearly and mines a tsi (must update my avatar!)

The TSI has a cam chain not a cam belt I believe.

If this is true then that is a compelling reason to get the TSI over the TFSI.

It looks like the 2.0 TSI has more torque at lower revs and smoother responses in all conditions compared to the 2.0 TFSI, IOW more refined over the TFSI than the headline spec figures would suggest. I'm still a bit surprised the TSI isn't ahead of the TFSI in any of the headline figures. Maybe it's more capable of subsequent up-speccing than the TFSI?

It seems like the 1.4, 1.8 and 2.0 engines have different bells and whistles not just capacity differences. I haven't found any definitive specs of which bell/whistle applies exclusively to which engine.

Did you test drive a TFSI? If so, have you noticed any differences?

I had a mk2 vrs before my new facelift vRS

the new engine seems very willing, and much quieter

even though its got only a 1000 miles on the clock now it seems a fair bit quicker, but that might just be the torque coming in a bit lower and being more constant through the range

but overall my initial impression is its much more refined

So other than possibly having a chain instead of a belt, along with a little more low-down torque, is there any difference in the block or engine/turbo/injectors design at all to achieve this improvement?

there was a thread on here not long ago which had the technical docs for the engine on..will see if I can find it

yes

The belt drive engine was an adaptation whereas the chain drive engine was a greenfields design.

Variable valve timing is different, packaging is different, servicing is slightly easier.

Just had a butchers at the previous link. It's very thorough, but explains what's new about the FSI.

1.8TSI and 2.0TSI are in fact EA888 range sister-engines with a difference in displacement.

1.4TSI is a EA113 range engine and is adopted from the older machines.

The old 2.0TFSI is also an EA113 machine.

Shouldn't that be EA111 ?

Economy is also improved, think it's about 3MPG better on the combined cycle. This does seem to tally, as my friend's Rocco is more economical than mine by about that margin. The unit does seem a touch smoother and is perhaps more refined/quieter. Not been in an FL vRS on the move yet, and I put the last two characteristics to better soundproofing in the Rocco (which is probably true as well!).

why oh why, cant they put the more powerful versions that are in the Leon Cupra/Ed30 Golf/Audi S3 in an Octavia, would be my perfect car!

It's called VAG product marketing strategy...

...and gives people with the modifying bug something to do

just hit the car with the mod-stick. It isn't expensive or dangerous to add a few more HP

I was under the impression the upgraded TFSI unit in those cars would be near 300hp with just a map and a few bits, whereas with the one in the Octy, it would take thousands? Ive already been hitting my derv with the mod stick!

Are all new Octavia VRS TSI then, not TFSI?

Sorry if this is covering old ground, but the brochure/website still say TFSI so didn't know if anyone has a link or something?

Edit: Any difference in economy?

See my previous post, #16.

All facelift Octy vRS petrols use the TSi unit.

Doh, sorry...I missed that post yday :rotz:

TSI introduced in the interior facelifted modells. As well as in the special edition for the GB market.

Biggest pro, next to the chaindrive, is the IHI turbo (which is bigger than the K03, but smaller than the K04). This makes the TSI easier to chip (bigger poweroutput without mods on the engine).
