Quite noticeable with it on I think. Took it off recently to see if it was the cause of my limp mode and whilst I’ve had it off it’s less lively. Seems to have a good impact

That is boosting hard! I'm about to go out for my bi-weekly shop and drive, i'll disconnect the wastegate connection and see if it behaves similarly (i suspect then it'd probably limp mode the moment i start it though). I'll film it too.

It sounds like it's overboosting (that surge of hiss as the rpms suddenly pick up real fast) considerably as it pulls to higher revs, possibly wastegate not opening, or the ECU wondering why tf the turbo is flowing so much more all of a sudden.

 

What happens if you drive gently until you get into 2nd and boot it while at ~2k rpm? If it's overboosting it'll pull really hard for a moment and then probably kick to limp mode.

 

Out of curiosity, did you replace all the gaskets and stuff? And are you sure the wastegate connection is properly connected?

I Floored it through 1st and 2nd it pulled very hard. then left it for 10 minutes. Now its completely fine. very confused maybe the very high pressure forced the wastegate open?

Help!! 

 

I have the new turbo on but after about 1 min of driving the EPC light came on. Almost feels like a boost leak but I've checked all the pipes.

You may need to adapt the actuator unit on the replacement turbo, so the engine ecu knows its position accurately.

Could have been stuck closed from being off  for a while. I disconnected the wastegate on mine and the EPC light stays on constantly and there's no power beyond 2500 rpm, it barely gets past 4000 even in 1st, torque low down hits hard though, presumably because the turbo's constantly spooled from the lack of wastegate.

In 1st gear i had nowhere near as much of a surge as yours with my stock turbo, so i think it's definitely a case of the wastegate was just stuck for a moment (or as anydmod said, it hadn't yet relearnt the position, if that's a thing).

Yes I think that was it. Just driven to work ( I have to go in once a week) and it was absolutely fine. It felt a little faster. Does it flow more air at the same pressure or maybe it's the placebo effect lol

The turbine is bigger and will flow better, my intial thought is that it'd have less exhaust pressure and as such take longer to build up boost, but perhaps because it's flowing more freely it's allowing it to spin up the turbo faster and have less backpressure at the same time.

 

Also as it has a bigger compressor it should be able to provide the same boost at lower turbo speed, so slightly reducing turbo lag, it's also more free flowing like the exhaust side, so it can pull air in easier, which would be more beneficial at high engine rpms where a smaller turbo peaks out and boost tails off (it will still tail off anyway but thats due to the mapping).

 

(commence ramble)

If it is better in every way, why they didn't put the slightly bigger turbo on to begin with, even if they did keep the same 90/110 tunes. There has to be some downside that they used a smaller turbo for the 122/125ps 1.4's and the 1.2's. It's not like it's a huge material cost, they'd probably benefit more from economy of scale if theyd stuck to the single larger turbo. Once the gasket set arrives for mine ill put mine on and do some pulls to see if there is any appreciable difference in power/torque.

 

My only thought is that it was to stop people buying smaller engine or lower tuned variants and just remapping to acheive 160 on the 1.2 or 185 on the 1.4 no matter the variants, the 1.2 stock maps to the 130 ish mark, the 122/125ps 1.4's map to the 155 ish area (the small turbo really chokes up the 1.4), and the 140/150ps ones map to 185 ish.

Yes the Vag group love reusing parts. maybe the cost of having two is justified as they sell lots of 1.2s and 122/125 1.4s .  yes  if just with a remap you could get 160hp out of the 1.2 i guess they would loose sales on the more expensive 1.4. I got bored of waiting for the gaskets but they have arrived this morning. i just reused everything i will make sure nothing is leaking tomorrow. Is the best way soapy water? Took me about 6.5 hours in total (It was a bit dark). if i did it again it would probably take half the time. so hoping the gaskets are fine. the oil drain took me a while. also before installing the turbo its worth installing the oil feed on the turbo side as their is not enough room to squeeze the tube between the turbo and the block. So after turbo was on it had to come off again.  Whats the expected time of this job/ rough price at garage

Annoying that they arrived the day after fitting! I'll be replacing all the gaskets and seals i can. The main ones i'd be concerned about is the exhaust gaskets, (there's also the metal crush ring thing that sits in a channel between the v-band from turbo-cat). The oil feeds will probably be visible if they're leaking (if you have brake clean, a quick spray-down of the area will clean away any oil from the installation so itd be easy to spot any leaks)

 

Did you remove the plastic intake piece or keep it fitted? I'm considering getting a silicon custom hose made for a direct turbo-air filter pipe, it might make a little more induction noise and flow a little better too hehe

Does anyone know anywhere that makes custom silicon pipes?

 

Found this adapter piece from r-tmg's induction kit, but imo there's nothing really wrong with the stock air filter box (i mean, the same air filter/box can manage like 200bhp with a 1.4tsi) and i'd rather keep it somewhat standard, a silicon hose would give a tad more noise, maintain factory airbox, and possibly slightly improve flow.

I left the intake thing on looks quite difficult to pull off/on when the turbo is mounted. The turbo came out fine with it on. That adaptor seems quite expensive

If it's freed up for now it should be alright, though next time you go out i'd recommend trying to get it really hot, not just one or two quick blasts, needs to be sustained heavy loads to get it hot enough to start burning stuff off.

Aparently a good soak of mr muscle through the hot side of the turbo (exhaust side only, don't touch the aluminium cold side with it!) is really good for getting rid of carbon desposits, followed through by a good dousing of brake-clean or IPA to rinse it out all good n proper.

While i'm still waiting on the gaskets, i might pick up some mr muscle and give it a flush out, not going to hurt it i guess.

yea ive taken it for a bit of a drive. was still pulling at 125 i ran out of road on  flat usually stops about 120.

 

Defiantly feels faster

Damn! It'll be interesting to see what it can do when it's mapped! Is yours 90PS or 110PS stock? I'm guessing 110PS as my 90PS runs out of steam at 113-115 on flat roads.

mines 110 stock and ive still got the race chip. i took it off when i was having the wastegate issue but its back on now

yea i can feel a difference not sure about top speed

Also been treating it to Tesco momentum 99 Ron as the price has come down and I'm not driving much. Not sure how much of a difference it makes

Ah fair, i dont' have a racechip or anything like that so i'll just be waiting for the remap, be nice if it gains some without though! The longer the turbo isn't on the car, the more i'm considering looking into having it hybrided

Honestly not a great deal from what i've found. It didnt improve acceleration or top speed for me by any noticable amount. (just the usual 1-2mph variance depending on wet/dry, cold/warm, backwind/headwind etc).

Even with a remap specifically tuned for 99 Ron vs 95 Ron, there's only a few bhp difference, on a stock map the ECU isn't going to gain/lose even as much as that, maybe a couple hp at most.

It can have other benefits like the cleaning aditives in Shell's V-Power 99, which did contribute to a noticably smoother running engine even under heavy acceleration, Tesco don't have anything special in there vs 95 though, just octane boosting aditives. 

Got a clip of a rolling 1st gear pull with stock 1.2TSI 90PS.

Hey all - I hope everyone is keeping safe and healthy.

 

I'd like to get some outside perspective - I'm currently on Team Dynamics 215/40/17 with the Eibach lowering springs and the handling is great however after about a year of running this setup I'm getting annoyed of having to slow down for every slight imperfection on the road which is always! 

For a while now I've been seriously considering about downsizing the wheels to 15 inch with a larger sidewall. In my mind this will hinder cornering ability slightly but it also means I won't have to slow down all the time because of imperfections on the road surface which will result in a more enjoyable driving experience overall.

 

Let's get the ball rolling! What are your thoughts on the above and what wheel/tyre setups are you running?

I've got my old set of 16 inch wheels laying around, aesthetically not in perfect condition but they're round and balanced and have pretty good tyres on them. You're welcome to try them out. I'm in Sheffield so local-ish to you too.

Same alloys as these, 215/45 R16. I'd say 15inch will probably be much too soft. There was a huge improvement in handling when i went from 16-17 inch, that said, i'm still on stock springs so far though.

Yeah after some research I am starting to think 15 may be a bit too soft, I may go back to 16 inch... 

Is anyone with auto lights able to help.

 

I am trying to retrofit auto lights and have been following this guide

https://wirer.sk/easy_light/

 

this guide says that pin and 1 and 4 need to be connected my sensor only has pins 2 and 3. is anyone able to check what is plugged into their light sensor on the dash
