Never get bored of watching a mk5 build…keep em coming!

I personally truly enjoy watching over the shoulder of someone who is very skilled at something, upgrading a Volkswagen is a fun thing to watch 🤓

[@DecimalTenths]

Too kind...👌 thanks dude

[@SpeedingTube]

You could make changing a wheel interesting mate, vlog it all! Having a shelf to raid full of shiny parts, living the dream! 😎👍

Great video, not something us novices would notice when fitted the acuator on the car down the back of the block

[@Flishlakv2]

The way you do things makes it easily understandable

[@AlexTaylorGTI]

Glad to see the TFSI videos back! Have been wanting to K04 my GTI for a while now, however this seems more ideal for me, can't wait to see what figures you get 😀

[@DecimalTenths]

Done a few and they do well. This one's a punt in all honesty....

[@AlexTaylorGTI]

Gotta be worth a shot, hopefully it does well 👍 Mines Stage 2+ currently but it didn't make the power I expected, not sure if that was because of the car or the tuner being a bit cautious but only got 268bhp and 300ft/lbs. The engine was completely rebuilt a year ago after the balance shafts failed, but the turbo wasn't touched so I'm wondering if its down to the actuator being a bit old and tired 🤷‍♂️

[@DecimalTenths]

@@AlexTaylorGTI Only the tuner can tell you why pal. Worn actuators do prevent a decent level of boost being achieved and from holding any to redline so it is a big cause for low power. If I can't make figures for a tried and tested solution I like to try and diagnose why and give suggestions on the solution.

[@BabyCharlotteschannel]

Havent had a gti since my last 2 mk2 golf gti 8 valves!! An '86 with 54kmi when i got it and then an '87 a few yrs later.. Now i have a '08 gti 2.0t lined up with not too high mileage on it, i am soo excited to finally have a turbo, somewhat fast one!!! *Cant wait to start getting some mods on it and get her handling nice and making some decent hp!!

[@Mr_Cholmondley_Warner]

Does look easy when you’ve got the subframe & exhaust out of the way. I’ve just fitted a hybrid turbo to my 1.6 tdi Caddy, was a struggle but it should make half the power of your Golf once it’s mapped 😂

[@DecimalTenths]

It is easier like that. 🤣

Hi!! What problems Have you got before changing the turbo? I ve got an Mk5 gti with oil consumption 1L- 3000km and a lot of oil in the entrance of intercooler. The car is running good, no smokes and not have extrange sounds from turbo. Is the turbo starting to death? Keep going with that videos!

I run the hybrid KO4 on my A4. The cheapos will last you about 10k miles with spirited driving daily. Keep a couple on hand lol

[@DecimalTenths]

Yeah this one wasn't a cheap chunky turbo, it's a genuine k04 with k04 core, it's just got a machined k03 comp housing so I don't have to relocate the diverter valve. We will see how long it lasts....🤣🙈😝

[@audittnegru]

Always interesting man 👌😎 nice testing with the actuator, used a brake fluid pump to test mine in the past, need to get a mityvac in the tools cupboard

[@jakel9410]

Just started watching this build and I love it. I have a similar turbo Technics hybrid in my 2.0TSI rocco. Made 355hp. great compromise for a k04 especially for my platform where they aren’t a direct fit. Look forward to seeing what’s coming 🙌

[@DecimalTenths]

Cool, I've tuned lots of k03 hybrids to 350bhp, so hoping this one is similar 🔥

[@TheRealLemongrab]

I have an 06 GTI TFSI, I’ve only put a cat back exhaust with aftermarket resonator and muffler, (Xforce 3’ cat back) and an Autotech cold air intake kit. What do y’all recommend I get to make a little more power maybe 300hp

[@DecimalTenths]

Full stage 2+ spec so Intercooler, decat, intake, high pressure pump, rs4 fprv, and a good pinch of luck to see over 300bhp. 280-290 hp is typical if the setup is healthy

[@seanobrien5520]

Seriously interesting 👍👍👍

[@DecimalTenths]

Cheers dude 👍

[@sethhenderson1036]

im looking to put a CTS ko4 hybrid turbo on my mk5 gti, would I be able to see the 350- 370 bhp numbers with the right supporting mods, or will the ko4 hybrid turbo limit that power?

[@DecimalTenths]

You mean k03 hybrid? I've never tuned that turbo before but most k03 hybrids make 340-350bhp. K04s and hybrid make 350-400bhp.

[@BlaxJakx]

How would I know the actuator is set up right without a vac / pressure line pump?

[@lucatronconi3558]

In your opinion, is it possible to do this actuator change operation with a turbo already mounted in the car? Thank you

[@DecimalTenths]

It is possible, but a complete pain in the arse, and is scuppered by most bolts not playing ball. Far easier to remove the turbo a d do it OK the bench in comfort.

[@HarrySchuil]

Where did you get the turbo from?

[@user-wt6hl7cw2b]

Great video Nick What needs to be machined to allow the ko4 to fit in the ko3 housing??

[@DecimalTenths]

It'd the k03 comp housing that needs machined to fit over a k04. Not worth it In my opinion, go k04, job done.

[@coreyvernon3245]

Can I ask you what spring you went for in the actuator?

[@DecimalTenths]

Stock spring pal. I'd even suggest that the Forge isn't the best one now. An uprated stock spring like we sell are better

[@coreyvernon3245]

@@DecimalTenths thanks mate

[@NoName-st6zc]

What's your idea behind this K03/K04 Hybrid Turbo compared to just simply using a K04? Are you hoping for better response/quicker spool low down?

[@DecimalTenths]

Nope, it's just for shits n giggles. Saves relocating the DV, that's about it. Tuned a few of these and they generally end up nice drivers and that's all I want.

[@NoName-st6zc]

@@DecimalTenths I'm very curious about the results. Since i swapped to the K04 on my GTI i always missed the low down torque from the K03. Above 3k rpm the K04 is obviously really nice and way more potent than the K03 but on your laid-back daily driver type scenarios (anything below 3k rpm with just part throttle), which quite frankly is the range you're mostly driving at on your typical drives, i found the K04 to be almost annoying at times, especially in the city. With the K03 you always had that sweet little boost shove at 2k rpm already which made it just so effortless to live with. Anyway, long story short : a k03 hybrid where i could maintain a decent daily driver shove at 2k rpm while reaching just about 320-340hp would be my dream turbo setup for an mk5 GTI. Living with the K04 made me realize that the fun doesn't necessarily have to come from bigger top end numbers, at least not on a car that's daily driven.

[@andrewtaylor9704]

Loving this channel, you’re just down the road from me so I may pop in. I’ve got a pretty pristine low mileage Edition 35; I want to keep it looking stock but it seems a waste to not unlock some extra BHP - what would you do if it was yours?

[@DecimalTenths]

Hey man cheers! Ed35s react really well to a stage 2 tune as they have the CDL engine. Expect 300ish bhp and a good chunk of torque. After that it needs mods to get the best out of it. Love an ED35, we've done a good few now

[@feonics8917]

You do make it look easy! Did you not want to re locate the DV while you were there?

[@DecimalTenths]

This turbo was a test to be honest, to see how an anti surge k04 with k03 compressor housing will work. I may just relocate the dv yet if it coughs on like I think it might..

[@feonics8917]

I do like your videos, nice one. One small thing, your audio balance between voice parts and the banging tubes is a bit off. The banging tunes are a bit too banging. 😂

Normalising the audio is something I do on every video, and I also watch the video back once exported, however as soon as youtube gets it, it sometimes sends the audio wonky. Especially if viewed on a phone. Does my head in. Point taken though 🤣👍

They're made very well pal, but depending on how the turbo is clocked makes a difference. Easy to just mod slightly and get it bang on.

[@richardwigley]

@@DecimalTenths so on an “OEM clocked” turbo they fit straight on? Could you not just clock yours so it fitted? Or would that mean downpipe fitting issues?

[@DecimalTenths]

@@richardwigley All depends pal, most need a little modification, even on stock turbos in my experience. You can clock the turbo to make it better, or mod the actuator or both.
