On paper they all look about the same. The EFR6758 seems a bit better than the rest but I couldn´t find any user data on the TurboZentrum package. What would you choose and why?

Couple of things to note on that one from their website:-
"PLEASE NOTE:
The installation on vehicle with right-hand-drive will take some modifications.
Important note about exhaust temperatur
In the past some customers didnt taked care about the exhaust temperatur. Even though the stock turbo is going with up to 1050°C in some cases, this is a) not necessary and b) the death for an EFR turbocharger. Please take care at your programming that the exhaust temperatur never exeed 950°C in any case!"
It's good that they point these things out. Many places wouldn't. The EGT warning does kind of make the EFR sound a bit less resilient than the other options.
I would go TTE420 personally.

I'd love to try out one of the EFR turbos, they're a common type used on the VR6 engines so would love to see how one works on a 2.0 TFSI engine. It's just a case of how much modification one would need for RHD vehicles, but at the price they quote it's good. But for simplest plug-and-play it's the TTE420 all day long.

When I had a VR6 turbo, guys using EFRs in the states were seeing a higher rate of failure compared to the tried and test Garretts. So I stuck with ye ol fashioned GT35R!
Anyway, would the TTE420 be a good option to improve spool and power (from the same PSI) over a standard K04? I don't want to push for 400+hp because it gets expensive, but wouldn't mind running Stage 2 eddy power but with a better, sturdier turbo that standard and improve spool up.

I saw Niki post on FB saying that with stage 2 setup and the right fueling additions the TTE420 makes 400 easy.
No doubt that the turbo is superior to most others on the market, maybe because its been tried and tested more than the other hybrids. Shame about the cost though lol
I agree. 400 should be more than enough unless your chasing figures or want an absolute animal.
Has anyone is a stage 2 k04 raced a tte420 to see if the cost is worth the hassle?

Good to know, cheers!
I think a replacement KO4 is a grand +VAT from the dealer (I wouldn't entertain s/hand or rebuilt personally), so if going down that route, I'm already £1200 in. Might as well throw another £600 in and get a much better snail!
I doubt there would be a huge amount of difference between the two when rolling into boost from say, 3rd upwards. I only say that because I've had a rolling race with a Stage 2+ Eddie (mine's stage 1) and the difference wasn't great. Talking edging away rather than pulling away. Then again, unless something stomps off like I've hit the brakes, I always class that as edging away :grin:
