S4 bigger turbo

[grat_master]

Hi,

I am interested I going stage 3 for my 2020 S4. Since I live in Canada, the Pure750 and TTE810 are too expensive so I am looking at either the Apr kit or a Chinese turbo from Jackal Motorsports or incoming CTS Turbo.

Is Apr turbo kit worth 1000$ more vs the cheapest offerings? I'm paying 3975$ all included for the Apr and 2950$ all included for the Jackal (and probably CTS too).

Will probably be tuned by Logic Street Performance.

Thanks

I would wait and see on that CTS turbo. Rather than support a US company at this point in time. As for tuning, there is a nice company in toronto that could sort you out: YD Motorsports. They have custom dyno tuning. I had a previous stage3 build quote from them using a turbo from TPC (Turbo parts canada)... They were managing around 500whp on pump gas, stock downpipe etc.

You can avoid the nasty duty, shipping, and exchange rate costs too.

It will be a Chinese turbo, they all are.

Aren't you tuned with logic street performance? Edit : no with Apr.

yes i have the APR stage 3. I got it last year when it was on sale.

The TPC turbos are china derived but assembled and sold out of Ottawa, Similar story for whatever CTS will be doing. Friends of mine have/do work for TPC and they seem to have a pretty good product line. Before they scaled up the owner even checked out my RS6 hybrids for me to see if anything could be improved on back when i built my b5. Solid guy.

And YD has been tuning lots of stuff. You should check them out. There are also a few decent audi tuners in the montreal area, but i dont know how many are still active. Rombotis, VAG come to mind.

I would *not* necessarily use YD Motorsports again. I had a WMI system installed + their TCU/ECU dyno tune. It made very good power. But, there were deficiencies. I would much more consider using them again if I had a BMW or possibly Mercedes.

Which tune should I get then? I'm close to Montreal but I don't mind driving to Ontario for that.

I will also wait for the release of CTS Turbo upcoming turbo kit.

As an APR turbo owner and on my 5th (or so) tune - I'd 100% recommend Logic Street Performance. No need to drive anywhere, except some runs and logging to dial the tune in.

If you get the CTS turbo (which makes some extremely impressive times on pump), same tuner - Logic.

That's probably what I will do. If I compare prices, cts turbo should be a bit cheaper than the Apr kit and lsp tune is about the same price as Apr tune. Might as well go full custom.

I asked yd for a price quote and they gave me 3000$ + taxes. That's way out of my budget.

Thanks!

lol, christ they cranked their prices since i talked to them 2 years ago. sorry man.

[TunedB9S4]

That's $1000 more than I paid. Wow!

[grat_master]

Yeah crazy price. They quoted 1850$ + hst for ecu and 1100$ + hst for tcu, plus I have to drive there so fuel + food.

I will go with logic street on their next sale. Last black friday it was around 2200$ everything included (dongle, shipping, deadbeef, etc).

I was also wondering what is the difference between a TTE810 turbo inlet adapter and a GT35R adapter? Aren't both 66mm? Why would IE sell both if they are the same size?

Anybody knows?

I asked ie and they got back with an explanation that doesn't make any sense. They said bolt holes are not at the same position. Which is not true since we can use the same 034 turbo inlet with different insert for all the turbos.

if it helps at all the pure750 adapter fits perfectly on the APR turbo.

Yeah I know that already, but thanks for trying to help.

They responded again and I feel a bit silly for not seeing this. A TTE810 turbo has the O-ring built in it, but a GT35R not. Therefore the TTE810 adapter doesn't have an O-ring on the turbo side and the GT35R one does.

Now I don't know if using a GT35R adapter on the Apr turbo is very bad or not. Yeah they won't be smooth to each other, but there is only a 1mm radius difference between the two. Shouldn't be that bad, is it?

[S4James]

I run the IE intake on the APR turbo using the IE Pure750 ring adapter, and its nearly a perfect match.
