starting discussion on the use of new VW 2.5L 5Cyl in Small Chassis

[david]

a quick search on ebay.co.uk doesn't show any results for that engine, very interesting, here stateside they are very easy to find and average around $500 (usd) for the long block.

just done a quick search myself,not a sausage.

[Error404]

nope, can't get them over here easily or cheaply. Wonder how much it would cost to get one shipped over on a pallet.

did you say group buy?

[david]

did you say group buy?

first in line then

[Error404]

I'm guessing that the internals will need to be upgraded anyway, forged pistons & rods, reduced CR etc.
But could be worth it for the lighter ally block and surely much better head design?

[Rocco]

and better weight distribution

[bartolomeus]

http://goo.gl/kTKv9 I found one in Germany, it has been for sale for almost 2 months...
The ones common in USA ar not turbo right?
Didn't know that VW/Audi made this engine...

Issam stated the head can be made to flow over 270CFM's (appraently more that a ported AAN etc can)

Intake ports



VVT as well iirc.

The vortex car by Golf 2.0t has pistons and rods. (540hp ish)

Over here it is a lot of hassle/cost given what an ABY/AAN with a set of rods will do.

I dont see a ttrs or rs3 engine being cheap right now.

Much more modern technology though.

Does Hank have a thread going for this? I didnt see any info on his website.

[Sleeper_Avant]

these I5`s in non RS3/TTRS format have been getting fitted to Golfs/rabbits for quite a few years now

they are typical, over designed, huge potential modern german motors

this is not the first time we have discussed this, am i right?

amazing engines, although taking away the purity/pedigree of "our" I5`s maby?

have you seen the BIG CC 5 pots some manufacturers produce? sure theres 6.8ltr 5 pots about!!
Hows that for a stroker LOL!

[andy10v]

What is the ecu like on these? Or is it standalone for swaps?

EFIexpress has a plug and play harness with VEMS for this application.

Couple of US companies making cams for these motors getting 285hp on engine dynos. The head geometry is pretty darn close to the Gallardo v10 5.0L before it was swapped to FSI in 2009. It is no surprise that getting half of Gallardo numbers is pretty easy in the 2.5L application. Gallardos were anywhere from 520hp-540hp stock and exhausts plus intakes gets them up to 580 pretty easily. My neighbor at the speedway twin turbos them and they get 1600whp out of them on the bone stock heads.

[targus]

wonder how much it would cost to ship one in a crate? with the exchange rate probably would not be too bad.

What is needed to run one of these in say a urq? take it custom intake/exhaust and flywheel/clutch?

Also after looking on american fleabay I can see you can get the engines stupidly cheap by uk standards $350's for a 61k milage engine, what are the internals of these engines good for before needing uprated even if they are not the tt-rs engine and just a boggo spec 5 pot?

[K7ERG]

Container shipment from US coming soon..............

[Pat D]

I'd like to know if it will mate up with an 01E box without mods, and other things like alternator, ps pump, engine mounts, etc.
