whats this new kit then all about, tell tell!

quite a few split opinions there.the k04 does appeal,they are almost the same price though,once you take into account mapping,fitting,parts availability and so on.esspecially if you get it from jbs,their k04 is £1300 odd just for the turbo.

KO4.01 is lots cheaper than that.

You can also get a k04-02x from a wrecked car for about half that price around these parts. I know the previous owner of my car got a new one in 2007 for 1600 EUR, freakin' expensive. However, the nice thing about the k04 is that while you don't get loads of power it's still pretty decent and starts to pull from about 2000rpm.

you can get a new hybrid k04 for £700

people like jbs hav very overinflated prices.

once testing is done very soon i will then let you know.

hmmm k04 but im abit biased

i agree with this new k04 hybrid from td using rs6 internals meant to be good for 320 +

td,is that turbo dynamics? i heard on uk golf forum the k04 hybrids with rs6 internals were hit or miss with regards to reliability.i wont mention any tuner names. are the garretts bulletproof? what would i need to change to fit a k04 hybrid?....manifold,injectors,turbo,inlet manifold???

the full stage 4 has only just been released as far as im aware. yes td is turbo dynamics

you would need the following for best performance

1 ko4 mannifold

2. bam injectors

3. 3 inch maf

4. 4 bar fuel pump

5. 4 bar reg

6. custom remap

7. k04 intake pipes

8. front mount if you havent got one.

9. water and oil lines

10. turbo

11. k04 downpipe customized to fit your system

thats about it i think lol

you can buy these second hand in kits on the forums if your lucky and can sell from £500 to £800 for the lot ( apart from remap)

What a load of old carp.

I've never seen so much rubbish in all my life.

Do yourself a real big favour, keep the car standard. Your car will be worth more when you come to sell it and it will cost you a lot less to run.

Alternatively buy a car that has already got the power you want.

why des??

i know you have been down the big turbo route and tried many a different turbo. you did it and spent a fortune so why can no one else do the same thing ???

alot of people realise that you can go buy a scooby or a skyline but choose to mod the vrs i dont get the whole dont bother doing it!!!! people choose to spend there money how they want when they want regardless of wether it makes the car more or less to sell on. and you will find most people dont mod there cars to make money far from it. if you and gerry for example was told not to mod your car its pointless you would have told them to bog off wouldnt you ???

i can see what your saying and prob right but its erelavant if someone wishes to do what they want there car there money.

did people tell you not to mod your car that its a waist of time etc etc ???

Everyone can spend their money however they like. You have your opinion and I have mine.

You have even answered your own question!

Good advise is hard to come by these days especially when it comes to buying big turbo kits, is everyone right, I think not. I don't like to give out advise that I know is going to cause disapointment or hardship, when I read the above I see this. Surplus money is very hard to come by these days and I for one am not going to encourage people to go down the destructive route I took.

Take a good long and hard look at the history of 90% of the 300bhp+ Octys on here, grim reading. If that is not enough evidence for you, you are beyond help. I wish I had a pound for every person that has ask my opinion, didn't take it and told me they have regretted it ever since (Andrew are you reading this???????). I only wished I had the same advise before I started modding the Octavia vRS.

Map the car, bolt bits on etc but leave the 300bhp+ for a better car, trust me I know. The Octavia vRS is not the right car.

Hey, what do I know, go a head, I like a good horror story. I can't even LMFAO because I know exactly what you will feel like when it happens to you.

All the best

Des

PS Gerry never had a 300+bhp car nor a big turbo, why? because he took my advise. Look how his car turned out.

why des??

As Clive has mentioned me by name I will add my comments:-

All Des is trying to do is save the poster a shed load of cash that he will never recover, this even I know from experience.

In my own case I did listen, and only went to a certain limit, where ther car was still a good every day drive, and, as some on here will confirm went like $*&% a shovel when I wound it up, and was totally reliable, and never broke anything, but still cost enough to get there.

Its all a case of how much you want to spend, and how reliable you want the car to be, go past a certain limit and it becomes a money pit, where you always have your hand in your pocket spending shed loads of money, and this also will be confirmed by some on here (Andyrew are you reading this?).

Add up the price of your car, then add the cost of the mods you have done to the car, then look round to see what you could have got that will do that sort of performance without all the hassle of modding it yourself, and you will see there are plenty of totally reliable cars that still retain a residual value when you come to sell them.

On reflection, all I should have done with my old Mk1 Octy vRS should have been brakes and suspension and rear ARB, then its a fast car with superb handing, which in itself is worth extra bhp without the cost of the engine mods.

Leeboy made a very valid point in another thread about why so many of the older forum members have either sold their cars or put them back to standard, and I totally agree with him.

yeah i will completly agree with you there. i do wish i had listened and do wish i had taken a different route. i will admit i wish i had gone down the K04 route from day one and had a reliable daily driver from it. i have spent a small fortune trying to get wjat i wanted and failed. as a few of you keep reminding me like on the way home one brisk evening.

i spent a fortune on trying to get the car how i wanted. it wasn't reliable, no matter how you looked at it. wether it be cracking manifolds, the downpipe, co sensors etc etc.

i totaled up what i had spent and i could have bought myself another octy rs out right. had i not gone down the gt28 setup i could have 2 octy rs's by now. does that give you a clue on how much of a money pit this is.

Des and Gerry and myself and a few others that have gone down this route know this to be a fact. there must be something in the about it as lee also having had a big turbo setup is now going back to a stock setup.

but thats just my thoughts and feelings and its up to you what you do with your car, good luck.

Can i be objective.....big power does equal big money but there must be a compromise?

Big big power like Des had is costly as he states and running serious power will cause reliability issues however his car was SERIOUSLY fast and powerful but not the norm. There are plenty of tuned mk4s s3s cupra r's out there that are running big turbo setups ,does that mean you cannot get reliable 300plus bhp power from the VAG range? (i hope not!)

I know the k04 is an option is however the IHI or td04 option not viable then? Would 320ish be unrealistic as an everyday car? Maybe the new kit that Clive is talking about is another possible compromise.

Surely the 20vt engine can handle 300 without it costing a fortune???

it all depends on what you want from the car. how you drive and what the cars daily drive is.

gt28 setups tend not to have a lot of power upto 3500 ish rpm. then it all comes in and comes in pretty quick. giving high power around the 4000 rpm mark.

my dialy commute to work was 25mins up the motorway. with no power low down, to get away from a persuing car, up to 70mph of cours,e i had to change down a gear to get the revs up. its all about what YOU want the car to do and how you want to do it.

thats why iam changing for a smaller turbo, i didnt say a small turbo, just something smaller than a gt28.

we will have to see how this kit that clive is sorting pans out. it all depends on what this turbo setup is capable of producing compared to how it spools up.

There are lot of big power "1.8T's" out there. What you have to do is look through the power figure and see the real car. Does it spool up below 2000rpm, can you drive the car as it was first intended, will the engine and ancillaries last for 100K+ miles, no, no and a big fat NO. Anyone can hit 350bhp with a 1.8T, it will just not drive or behave like a normal car.

The closest to a perfect setup I have witnessed is a KO4 with and equal length mani (plus other bits). This gave instant power/spool up and drove like a standard car but with lots more power.

To get an idea (or not), me and my k04 got pwned today on the highway by a TVR Griffith. Kickdown in 5th at about 120km/h and when I hit 180km/h he was 200m ahead in the distance Maybe I should've shifted to 4th or 3rd, but didn't really think he'd be that fast

very true des and gerry i agree as a whole what you are saying and des your in a far better place to make comment as whats good or not as you just about coverd everything with your build.

and i would also agree and this is why i have stayed with k03s and if i was to change it will only be to maybe a k04 hybrid with equal length.

so i will sit down and shutup now lol

i personally think the gt28 is the worst choice of turbo for this car or any 1.8t it might be more usable if it was strapped to a 2.5-3 ltr engine but 1.8t never. when the black one was one the road before i joined the smashed it up club was truly awesome with diff brakes and suspension done running 225 still made faster cars on paper look silly. with a better driver behind the wheel it would have been even better.

to some it up big turbo -= lots of money and a waist

k04 great setup if you hve the supporting mods done

k03s as above

listen to them but if you really wanna do then you can your car your money

yes i agree with whats been said, gt28 imo is not the right turbo for my driving style, who wants all their power after 3500 rpm!

I want as Des said a turbo that will behave nearer to stock ko3 spool so other than a ko4 upgrade or hybrid ko3s perhaps is the 300bhp rather than the 350 mark not achievable with the IHI setup as i understood this to have faster spool and nearer to stock turbo charactistics without going over the top with the power and screwing the engine?

thanks for the great advice guys. i think i'll go for the k04 hybrid as my car is already making k04 torque.would anyone recomend a place to get a hybrid k04 from.

Try backdraft as they did have a special offer on.

Can I add the ihi set up I was running was totally reliable. The only time

the car failed was with a perished fuel pick up hose in the pump.

The oil consumption issue was an expensive hick up but unrelated

to the turbo. Car is going back to standard so it can be used as a

sensible daily driver once we move house and I have to sell one

or other of my octys. Oddly I'm selling the 09 plate vrs because

despite it high competent it has little in the way of character.

If people want to run big power then go ahead. You'll only really

enjoy it on track, roads are too busy these days unless you

frequent north Wales outside tourist season or set out in the middle

of the night. Progressive mapping is the key unless you're

prepared to always be in the right gear, but that can be tiresome.

So the oil issue you had Lee was nothing to do with the turbo? did that occur before fitting the turbo then?

The only problem is as far as i can tell with the IHI setup is the turbo cannot be rebuilt, shame as i have one sat here needing a rebuild so its useless!!

Progressive mapping is the right way, who did your map? I take it you could drive the car 'sensibly' too without it being a pain to drive?

What kind of fuel consumption did you get of of yours when driving sensibly?

dont forget that lee's setup was with a 2.0ltr bottom end and fully forged and reworked head so he had a very strong setup.

Blimey. sounds like he did it properly then.

A big turbo car can be as reliable as a small turbo car, if you do it properly. Which obviously means a truck load of money and requires someone with the knowledge/experience to do it. But we really are talking silly money to make it properly reliable. I wonder how much the WRC teams spend on engine development?! I think that's why it's so hard for an enthusiast to get the best out of a big turbo conversion.

Totally agree with all the big turbo performance comments. By the time a big turbo'd 1.8T has got on the power, the highly tuned car with the standard turbo has long gone!! I'm sure the big turbo would soon suck it up on the motorway though!

After 2.5yrs of ownership I'm still on the standard map, and still loving it. I'm fairly certain I'd kill myself if I had a big turbo!! It's all about the corners anyway!
