1.4 TSI engine.

Postby bigbadbob76 » 03 Oct 2018, 12:47

I guess these engines are still too new for anyone to have put one in a T25 yet.
I'm adding a mk6 golf GT to my stable in a couple of weeks and looking at the power and more importantly the torque curves for the 1.4 TSI engine (supercharged and turbocharged) it would blow the DG engine out of the water if I ever had the misfortune to write the golf off. :lol:
sure it's a screamer, making it's 160BHP at 6k rpm but it makes 134BHP at 4k rpm so you don't have to scream it.
and with that supercharger giving it 177ftLb of torque over a huge range, from 1750 up to 4500rpm it's just begging to be put in a T25 if the gearbox would take the strain.
Wiring it would be fun but no worse than a Scooby I wouldn't have thought.

177 lb.ft? Thats 240Nm, the upper limit territory for the 094 transmission, especially in a heavy bus.

The 1.4 TSI has a reputation for going pop afaik (timing chain stretch) they use a lot of oil and are fussy about fuel, 98 RON is needed.

yes, there was a spate of timing chain failures related to the hydraulic tensioner and a bad batch of chains.
Later builds were fitted with upgraded timing gear.

"they use a lot of oil" :lol: sounds like a T25. :lol:

For a modern engine, its inexcusable imho.
Our SA 2.6i uses a little oil but its got about 170k miles on the clock and 50k of those are mine!
So many "new" engines seem ridiculously fragile and prone to basic shortcomings, things like bad timing chains & tensioners should be in the history books, not a recurrent design fault.

I have one in my Golf & it's a great little engine. I've always used 95 petrol, it hardly uses a drop of oil, & has done 70,000 miles without so much as a hiccup.

Did quite of bit of research before I bought this car. Spoke to a couple of VW mechanics who said they'd had a few problems with the double turbo charged versions, the lower powered single turbo seems to be less of a problem. As an owner of the single turbo version all I can do is keep the oil topped up & changed regularly & not thrash the hell out of it. I've had 70,000 miles trouble free so far so fingers crossed.

The one I'm getting is the twin charged version, supercharger+turbo charger rather than twin turbo.
I've been recommended to not let the engine turn backwards when parked in gear as that can make the chain skip a tooth due to the tensioner design.
ie: if parked facing downhill, either leave it in neutral or in first so if it rolls forward the engine turns the right way.
If parked facing uphill, leave it in neutral or reverse so if it rolls back the same applies.
As I'm in the habit of leaving any vehicle in first when parked, this could take me a bit to get used to.
I don't trust handbrakes. at least automatics mechanically lock the shafts from turning, that's the only thing going for them for me.
On my old Saab on the other hand, you had to park in reverse or you couldn't get the key out of the ignition.
