What kind of issues were there? Considering buying the kit and would like to know about potential issues.

Okay I figure some details are probably okay from a customer standpoint. And as a customer, I just didn't and don't want to get in the middle of a he said/she said.. I just want the turbo to work. I also want to share my experience so others here do not have similar issues.

The wastegate would not pass the adaptation no matter what the shop did. They found that the wastegate lever on the turbo was welded in the wrong clocking position causing the rod to be too short. Apparently there is an extension kit - not sure if it would have applied in this situation, but it wasn't used. No new turbo was shipped. The shop was able to work around the issue.

Keep in mind that by no means am I very technically inclined on the inner-workings of the turbo and wastegate/actuator system.

Question. Does this turbo not whoosh at all compared to the IS20 when you let off the gas? Is it the anti-surge housing that causes this?

Having been around for the 354 pages of this thread, and keeping this on my radar if my IS20 ever shits to bed, I'm pretty sure one of the major notes I've seen is that it should sound wonderful because of the anti-surge housing. I could be misremembering though haha.

Whooshy boiz on lifting off the throttle are gone. Big turbo whistle. If you let off from WOT under high load will get you some flutter.

A lot more intake noise on building boost.

Yeah I read earlier that some people were hearing "enhanced" whooshing noises but that is definitely not my experience...just a lot of whistle, which sounds amazing. Lots of suck, no blow lol. Haven't noticed any flutter from letting off WOT, at any load or RPM.....yet.

Anti-surge housings are for preventing surge while on throttle. This turbo makes all kinds of great noise. I think you had said that you were still running the stock airbox, which I've done and it suppresses a lot of the turbo noise, wooshy noises included. I run the APR open Pex intake and the sound is perfect. I hate obnoxiously loud intakes, I had Integrated Engineering's intake on my GTI at one point and I hated it, besides the fitment being bad, it was too much. I think mostly because it used aluminum on the intake tubing. APR open PEX intake connected to a generic silicone intake tube is just enough. You'll definitely hear the whistle more and some whooshing, with windows up it is not as noticeable, which I prefer.

Thank you.

The stock waste gate is reused fom the existing turbo so I'd chaulk it up to bad luck rather than being an issue with the DTR turbo/kit.

They went through two actuators. The shop was worried that the wastegate lever being welded incorrectly was a contributing if not leading factor in causing the actuator to fail.

Yeah but where there was an audible yet subdued whoosh with the IS20 on the OEM airbox, there is absolutely none with the DTR...unless the whoosh on the DTR is just quieter generally and that's why I'm not hearing it? The whistle I believe is perfect...could be a tad louder.

How difficult is it to adjust the voltage of the actuator with the turbo on the car? I was going to reuse my is20 actuator, but if the engine needs to be running to check the voltage it sounds like a long winded process to wait for everything to cool, and possibly not have the room necessary to adjust...

Does anyone with a GTI provide their thoughts on the drivability between the FWD and AWD files?

FWD file feels like an absolute slug in 1st and 2nd — like no, to minimal boost. If you have sticky tires and can articulate your right foot, get the AWD file.

Fwd is designed so you never break traction, which equals speed, in theory, but I swear up and down the awd file is faster and much more enjoyable around town.

Thanks, do you have the electronic LSD?

The FWD file was developed on my car, GLI with electronic diff, 255/35-19 PS4S tires, and good roads. We considered it the "best case" scenario for traction... While I 100% agree that the AWD feels faster, it is not. I think the fun of roasting the tires and trying to pedal it is too much fun that it overrides that actual speed the FWD file gets.

We could not get better 0-60 times than we did with the current FWD file; I think the best was 4.9 seconds, but consistent 5.0/5.1's were easily attained.
