Here's a local'ish option.. Refurb to OE or upgraded options.. I'll have a chat with them and see what's what 🤞

This is one I've spotted and is on my 'maybe'.. so a Hybrid ball bearing IS38 for around £800 which isn't bad for a full hybrid. Vortex is another Hybrid that comes up a lot and apparently opens up big BHP increase.. but it's not cheap. Another I've spotted is a the Mamba Hybrid. What I'm hoping to find is a turbo specialist who offer different levels of rebuilt.. new core and refurb to OE, refurb with design flaws improved on.. stronger basically and maybe a rebuild with tweaks.. bigger, faster, bit more boost.. I dunno.. will have to see what's out there for sensible money.

Bit of an update.. I've taken a punt on a used IS38 off a 2014 Golf R with around 80k miles on the clock.. only £100 so worth a punt. Still haven't decided whether to just keep it tucked away as a spare just in case or crack on get it refurbed. My thinking is, I do want to remap my Superb 280.. I just haven't decided on the map.. some of them might be more aggressive on boost than others.. will my 100k miles turbo survive? Wait and see? Or pre-emp it? And if I do refurb this spare one.. standard back to OE refurb.. or try and get some improvements (without going silly on cost) 🤔🤔🤔

On the money again dude.. I bought one last night for £100. 06K 145 722A part number taken off a Golf R with 80k miles, so I'm feeling pretty confident it's the right one 🤞 Next research is who best to refurb it if needs be. The question is straight refurb or refurb with improvements 🤔

You know your EA888s 👌 Engine No: CJXA134060 Turbos are my current research focus.. Trying to work out if I the IS38 really is a weak link and what's the cheapest/best route to getting it refurbed with improved reliability.. improvements over OE a bonus but not something I really want to spend a fortune on. I've found a localish Turbo specialist so I'm going to call them up and see what they suggest. Only downside seems to be you need to take the turbo off and send it to them for refurb so that's would be a bit of time without the car. Hmm

Yep, mines up to 100k now and makes a suspicious noise so I need to think carefully about a remap.. don't want it to go pop but looking at cheapest/best way to solve the problem if it does.. Anyone come across this...? Any idea how I would identify which one I have? "Early 702n turbos prone to going. 722H better."

The original post I meant to put 278, basically it's an original 280.. brain fade.. can't edit it.

I've come across this - DNFE at least. So are these the engine codes for the newer Gen 4 engines? Mine's older so was pretty sure only a Gen 3. I've now had a read through the docs that came with the car and confirmed she's a CJXA. So definitely a Gen 3. Would love a Gen 4 obviously but I'll just have to make do eh 🙂

Look at an internet search for IS38 Cartridge.. They're obviously churning them out in China and I'm guess quite a few of the sub £100 ones on eBay are probably from China too.. But AutoDoc are offering Ridex, Evoron, Alanko, Meat & Doria.. Never heard of any of them but if AutoDoc.. I trust them 🤔

Temping but I want to keep everything looking stock.. So a rebuilt IS38 with improved internals is a really attractive option. The claimed improvements address design flaws and reliability of the original OE unit. BUT also claim to improve spool speed slightly.

Yeah, I had a nose around Awesome's turbo offerings but they are mega bucks! Hence putting it out there I guess.. Awesome do an IS38+ which I think is where they refurb the internals with ball bearings.. £1600! IF (an it's this IF I'm trying to get a feel for) the aftermarket IS38 cartridges are good, they're between £100 to £150. And claim (?) the have engineered out some of the inherent weaknesses in the original spec IS38s 🤷‍♂️

Yeah, my thinking is, issues with the IS38 turbo seem to be pretty well documented, especially early cars. After market solutions have inevitably popped up everywhere. The question is how to spot the good ones?

Hey guys, old topic I know but I'm just having a good read up about the IS38 turbo on my 2016 Superb 280. She's been well looked after but she has done 100k miles and I think I can hear mechanical turbo grating noise.. maybe. I've been looking on eBay at upgraded IS38 cores as an option if she ever goes pop.. or maybe even as a precaution.. Many of the adverts (there a lot) claim a number of improvements over OE. Here's the text from one of the adverts . "This CHRA is a DIRECT FIT, plug and play and requires no modifications to install. Thrust bearing is upgraded with full 360 thrust pad, enlarged triple oil ways to improve load handling and reliability. The Turbine wheel is also upgraded to a staggered gap high temperature type, ideal for low back pressure exhausts with larger bores or removed silencers. Finally all CHRA are high speed balanced to motorsport tolerance to ensure maximum reliablity. This is the strongest standard replacment CHRA on the market" Anyone else done thand how was it? Thoughts?

Can't see the pricing on their website.. I'll have another look on my pc at work or call them I guess. Quick check.. the DSG remap sounds ideal.. what's the ecu remap like? Not too aggressive?

.. but, I really like the sound of this one. So they're saying clamping pressure is dynamically adjusted by engine torque so it should cope with torque loads as you add performance to the car.. anyone have this gearbox map? Any idea how much it is?

Yeah, they seem to really know there stuff.. I thought I'd spotted an option for an engine ramap and matching gearbox map for €999 although I've just had another trawl through their website and can't find it. Tempted at that price but.. 👇

And one more for tonight.. Driving the car today I got a big whiff of cat fart 😬 I guess that's my warning sign the cat is on its way out.. If it is.. the question is do I just get an OE replacement or a non standard replacement. Or do I invest in a high flow cat.. hmm. Any ideas on difference in cost and impact on power, noise, etc?

The more I read, the more worried I am about how much torque that DQ250 box can handle. The info on the TVS Engineering website seems like they really know their stuff and that it's really important to get it right or the box can't take it. What's everyone else successfully putting through theirs and have you had any issues?

I've just bought myself an OE Golf R rear ARB and just posted my finding on sizes in that post too. The gist of it is, if my googling is correct (?) our OE Superb rear bars are only 19mm . An OE Golf R bar is 21.7mm, so nearly a 3mm increase. If you had a Golf R, to get a similar improvement you'd need to be going 25ish.. Anyway, I'll find out soon enough once it's fitted 🤞

After googling the hell out of this, I can see why a 22mm would be a disappointment on a Golf R.. As far as I can see, the standard Golf R rear is 21.7 so only 0.3 difference. Next to nothing. A 24 is an extra 2.3mm so I guess you'd notice that? I've just bought a Golf R bar for my Superb and the original I think is 19 (?) so if that's right, I'll be going up 2.7mm which is hopefully a noticeable increase. Fingers crossed..

Ok so Golf R Estate OE rear anti roll bar sounds like the way to go for me. A small and fairly cheap tweak, and all looking nicely OE. Winner winner 👍 Remap choice I'll have to keep digging. I noticed the APR gearbox remap they mention increasing clutch pressure to keep up with demands of their high torque stage 1 map. Revo do that in their stage 2 gearbox map so I'd probably want that one. Revo stage 1 with stage 2 gearbox map. Or APR Stage 1 high torque with their standard gearbox map.

Rear ARB is definitely on the list of possibles.. I've read somewhere that possibly a Golf R Estate OE bar fits the Superb.. the cars are the same width.. it's 21.7mm.. any idea what the standard fit superb bar width is? Bilstein B6s are the other mod on my list.. keep the standard ride height and upgrade when the stock shocks need replacing..

Yep, definitely going for a flash remap.. current top 2 options in the UK seem too be APR or Revo.. Revo do a stage 1 and 2 and 3 different stages of gearbox flash.. about £800 for the pair. APR there's no stage 2 but apparently their stage 1 is pretty much stage 2 anyway. Still trawling the web for feedback on people who've tried both before I decide. The air intake stuff was a definite and then I read it makes a bit more of a whooshing sound.. great when I was in my 20s but these days I like the quiet.. I've ordered a performance filter and the OE air blanking plate.. and might maybe drill out the air intake.. we'll see. I'm very tempted by a proper R600 air box but I don't want insurers to spot the mods.. Turbo elbow on the other hand I might get away with.. as long as the noise isn't silly.

Ah yes, I've spotted the DCC slider mod.. I'll have to have a ring around and find a VAG independent garage to see what they want to do it.. not entirely beyond me to work it out myself and buy a VAG.COM .. or not risk bricking the car. To be decided. Pads and Discs I guess I can look at next time they wear out.. maybe that can be from a different budget pot if they're not crazy expensive 😎

Here she is. Quietly understated. Just how I like them ♥️
