Title: G40 dsg tfsi
Post by: GR40 on May 04, 2014, 11:31:34 PM
I was looking around (about a month ago) and found this for sale, on a Greek car selling site. I wasn't sure if it would be interesting to anyone here but it was to me and though I should share. Greeks, we are both geniuses and totally retarded at the same time.

Nice find!! That's awesome! That subframe looks trick! Can't see a price or description. Pretty cool though

The description is in Greek and the status of the price is "ask me for a deal" (meaning you ll have to call in person to agree on a price) here is the link for the first page. I 'll translate it in English for you!

(Engine swap to dsg tfsi) The car weights just 840kg fully dressed with carpet, trims and glass windows... its ideal for drag or street use (streetracing).. everything is functional including the paddles.. its fitted with a κ04ttrs turbo and a high pressure pump.. Sparco carbon fiber seats and much more. It is currently working at 0.6 bar and it goes like a shocker ball (damn the Greek slunk, he means it is fast) with exceptional dragster time figures.. It rides like a normal car, it has all it's paperwork.. anyone who is familiar with the model can tell what it is capable of.. call me for more details.

Looks pretty mad!

How does that suspension even work with two track control arms basically in the same location?! Retarded!

Same as with all the triangle shaped arms! Not claiming this to be the most efficient arm I have seen but I bet its better than putting strain at the chassis legs that we all know are prone to crack! Also to fit the engine he had to remove the sway bar mounting points and that leaves no spot to where u can mount a control arm!

It's not the same as a wishbone at all.  Normally you have a bush or member to take majority of lateral load and the other can cope mainly with fore/aft.  This setup looks like it'd struggle to deal with lateral load.

I agree that it may have issues and I don't see either how this could possibly be an optimum design but like I said before, I doubt he had an alternative. The tfsi is taller than a PY engine (thus is sits a bit lower) and its bigger in all dimensions, the dsg would obstructs an arm mounted forward and the limited space may had left him with no alternative! I can see though that the secondary arms mount at an angle with the original mounts and I can only assume that when the car is lowered on its wheels they could possibly provide some resistance to lateral load! Hey, I am no suspension expert and I doubt this was build for anything other than straight lines but it is what it is, a polo G40 with a tfsi and a dsg maybe the first and maybe the only one ever. Someone had to try and fit one and through trial and error this could become a viable engine swap or a total waste of time.

Good work for getting it to fit (and run?) but I'd be concerned with chassis strength and suspension geometry. For sure it's worse than standard, which takes some effort.

Other option would be either a very low subframe under the gearbox/engine to the front radiator bar pickup mounts on the chassis legs and hang another strut off there.

Still, good to know it doesn't fit  ;D

Alternative which might well fit is one of VW's 3cyl motors (12v) + DSG.

Quirky, but for performance alone the loss of a cylinder isn't compensated for by the addition of DSG in my opinion.

If the purpose of fitting the DSG is to gain quicker shifts then either a H-pattern dog box would prob. more effective.

If one wants to have the power as well then Yoof has demonstrated 8v turbo is capable of producing more than enough.  Then a 16v conversion again would be less compromised.

So it's flawed and pointless?  Harsh but true...

It costs 5000 euros

DSG quicker than a H-pattern dog box I think (mine is) and has the advantage of a shift without torque drop.

I still like the idea of a Polo with paddles  8)

Yeah DSG is bound to be a little quicker, but not much and weight penalty etc. would cancel of of it out?  DSG is certainly impressive in a road car.  I've never driven a dog box but local 106 Hillclimb car sounds like theres no interruption, only the briefest of lifts to unloads the transmission.  Sounds ace!

The engine is un modified though, it could be tuned to match the power of a highly string py engine? If you compare it to a standard polo engine it's pretty cool
