As above really, I've got a K03 GTI and I'm planning on going stage 2+ early next year and wondering what the best mods are and what numbers to expect.
What I currently have:
Standard downpipe
Custom downpipe back exhaust with 200cel sports cat
Revo cam coated intake
Custom remap
What I plan to add:
Precat removal
LOBA HPFP
THS intercooler
I already have brakes/ suspension etc.... So purely from a performance perspective is there anything I should add to/ change about my list? What numbers should I expect?
The reason I have a standard downpipe is because I want to keep low down torque and I don't think a K03 needs a bigger DP, if I'm wrong on that let me know.
Any advice appreciated. :happy2:
-
Yes, get a downpipe. I have a 3" downpipe de-cat on mine and it has plenty of low down torque. I'd also buy a china cooler for half the cost of the THS, and put the difference toward a WMI kit
-
i have a nice stage 3 clutch in the forsale thread lol.
Not needed but still good to have.
Sounds like a nice spec your puting together mate.
-
Engine mounts :happy2:

I've already got the THS since I got a really good price, also allthough the China coolers look the same I doubt they're the same quality and probably wouldn't give the same temp drops of a branded one.

I've heard a couple of negative things about the Sachs stuff actually so I'll stick with the Helix organic clutch, thanks for the offer :happy2:. Yeh I'm hoping it'll be able to suprise a few things when its done.
Engine mounts :happy2:
I'm going to get the Superpro one as Alex suggested it when I had my service done last month but couldn't get the damn bolt off and didn't want to break it. I've never really done much research into engine mounts as I didnt think they made that much difference, are they really that noticeable?
Thanks for the replys :happy2:

Really. Like what? They are a bit pricey right enough brandnew.
I stuck with standard clutch. Pretty much running same spec or will be when you get everything made 300bhp. Ths intercooler makes a nice difference.

They're the same cooler and have been proven to flow at much higher power levels than a K03 can manage, some people just prefer to have the cooler without the branding being removed :wink: Mine was a big improvement over the standard cooler, and keeps temps within a couple of degrees of ambient when on the move. I did a lot of logging, and even after repeated WOT pulls through 3rd and 4th gears, IAT stayed within 5 degrees of ambient :happy2:
Irrelevant if you've already bought the cooler though. Downpipe would be a good idea, as would WMI along with the HPFP

Oh wow I'm suprised they're that good, yeh THS is a lot for K03 but I'm leaving enough room for a K04 at some point maybe. I like the idea of WMI but might be a pain since I do 12000+ miles a year, might look into that if I go bigger power at some point though. Cheers for the info :happy2:

Someone I know had one on a Seat K1 cupra and it was quite firm and jerky, then about 4 months in he had an issue and Sachs found a way out of the warranty, some excuse about fitting etc. Anyways he might have just been unlucky or unreasonable but it put me off a bit.
Also from my research people seem to recommend the Helix organic over the Sachs stuff so that's what I'm going with. The Helix organic and new DMF is what Alex at AKS said to use and I might be wrong but I think he doesn't supply Sachs products anymore because of problems. I might be wrong and if so I'll delete that but I'm pretty sure I read a while back he doesn't stock them anymore.

I never got to try mine so god knows lol. Like most things always someone had a problem.
In saying that though not seen a bad thing about the helix.

@howie1987 (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=10115) That's a very good point I hadn't realized until you said it I'm actually yet to hear a bad review on the Helix, obviously someone has got one but I haven't seen it yet. Supposedly its running 417lbf and doing fine on a car somewhere. Also its one of the cheapest so can't go wrong really. :driver:
-
Every clutch i have owened with a sachs plate has took about 10 minutes to change gear.. I know someone running helix on a big turbo but only low boost about 400ftlb and its done lots of track

What are you running in yours?
-
Clutchmasters fx725 with twin race plates
-
So you reckon the Helix is good enough to take anything a K04 could throw at it? That's probably the most power I'll put through this car.

If you add WMI on with a K04 you can get 450lb/ft with a fairly aggressive delivery. It may struggle with that, but MC71 has one of the highest outputs from a Stage 2+ K04 (361bhp) and his is fine.
Just make sure your tuner doesnt exceed 400lb/ft to keep the clutch happy

I didn't know you could get that much torque from a K04, I doubt I'd ever push one that far though TBH. I'd either get a different car or go mad with it and I'd have to change things anyway but that's way in the future, I'll stick with the K03 for now :laugh:. Thanks for the info :happy2:
-
Yes helix will be good for anything a k04 can do unless running stupid aggresive torque as said above, turbo would probaly pop before the clutch then tho lol

Think this thread got off topic a bit, so what could I realistically expect to get with the mods listed?
From what I've read I'm hoping for 285-290 BHP and 350lb/f +

Sorry mate.
Yeah they figures sound about right. Will make a massive difference to the car.
Similar mods. I got 300bhp 346.2 lbft
-
300hp on a K03 without WMI? What mods and whose map & dyno? I'd be very skeptical of those figures as you need a nigh on perfect setup to get a genuine 300hp
-
300BHP give or take sounds good. perhaps no need for k04 until you get bored of the power?
I have a meth kit so just need to throw all the parts the car
-

That's my plan, stage 2+ K03 this year and then in a year or so I'll go K04 and then 18 months or so after that my loan is paid off and I'll go mad with this or trade up to something else.
But things never go to plan.......

Goodluck with car mate. Might be money that people say is wasted but at least you will get some fun out of it. Well worth it.
-
Yes mate, post them both up if you don't mind, some impressive figures given your mods
-

Cheers, I would much rather waste my money on the car than drinking or overpriced clothes etc..
Chasing M3's Porsche's and other 50k cars is my fun :laugh:

I have a R-tech stage 2+ gti , I have the following hardware fitted:
BCS 3" turbo back sport exhaust (200 cell sport cat)
REVO intake
LOBA hpfp
Airtec stage 2 intercooler
R8 coil packs
Helix upgraded organic clutch
The peak figures were 280 bhp and 356 lbft
But over the midrange I gained 70 bhp and 70 lbft over my old R-tech stage 1.5 map !! , and that's the real advantage of the stage 2+ map and decent hardware

Very nice, so its more of a midrange/ lower down improvement than peak numbers over a stage 1? I hadn't really thought of that before, just got caught up in the numbers. Thing is its the low-midrange power that makes a car feel faster and more drivable.
My current map was done with just the Twintake fitted and I got 260BHP and 290LB/F with max torque at about 3500rpm. If I could have 350LB/F at 3500rpm and more BHP low down that could be quite :driver: :driver:.
-
K03 turbo is all about mid-range power and no lag :star:
My old GTI with just a stage 1 map was very nearly as quick as a stock Focus RS 2.5. I did some runs through the gears with one and he pulled a little. A run from 50mph in 3rd gear was neck & neck :laugh:
Just shows how quick even a K03 turbo car could be. Recon a 2+ K03 would be great fun

Aye. I'll have a look for it later and copy it.
I didn't put the image up till lastnight. I don't know why its hard to believe. Also if you knew anything about tdi then you would know they are one of the most honest garages and they wouldn't let a car leave if it wasn't right.

Im not doubting their work or the cars performance, especially if Niki mapped it. I know nothing of TDI or their Dyno
What i am always skeptical of is figures from Dynos without any comparisons. Niki's Dyno for example, many many cars have run there and it's almost considered a reliable benchmark.
Is yours THE car that made 299hp on Niki's Dyno? Pretty sure that's the highest he's seen on a K03, but i thought the setup had WMI

Well tdi north are arguably the best in honda tuning in britain. Yes i know totally different game. They have teamed up with amd tuning i know they are bad words on this forum sometimes.
Bit of a long story to what happend which i was saving for my build thread when i make it lol.
Since this isn't my thread i will post you a link once i make my build thread and you can see the story behind it. I think it has a good ending lol. All i will say it didn't make 300bhp on nikkis dyno but wait for the story behind it.
Sorry for cluttering your thread op.

Yes mate after all the good reviews on here I'd be mad not too, I went to AKS based on reviews from here and that was a good move so I expect Rtech will be too. I'm getting the bits together now then at the end of March/ early April the car will go to Alex at AKS to get all the work done then I'll pick it up and go straight to R-tech.
Its my 21st birthday on April 7th and my present is basically a chunk of Alex's bill which is why i have to wait. I wanted to get all the info now so I know what parts to look out for if any sales/ deals/ decent second hand ones come up for sale.
What's being done to yours?

Great stuff you will enjoy the R-Tech experience. . . Even Rich83 & TFSIMike are planning a visit now :drinking:

Very nice mate, it's interesting to see how much difference the HELP makes, originally I didn't think one was necessary but glad I'm going for one now.
Hopefully they'll do a RR day or something next year, would be nice to meet some of the people and see the cars in the flesh.
-
They usually do a charity rolling road day in the summer. It's good fun :happy2:
-
Do you know what boost levels you are running on those R-Tech 2+ maps ? To get that level of torque out of a K03 you must be running some crazy high boost levels in the mid range and that doesn't leave much room for seasonal temperature variation (i appreciate the UK doesn't get that hot) and driving around areas that aren't really at sea level. Was pretty sure I read the warmer the temp and the higher you go elevation wise , the more boost the ecu has to dial in to make the power, so if you're already on the limits , then what ?
I didn't see anyone mention the RS4 valve in their mods list, I thought that was a prerequisite at 2+ on a custom map.
Have read nothing but great stuff about Nikki's work so it's a genuine curiosity especially as not living in the UK I can't get an R-Tech map
-
The RS4 valve is for the K04 guys, I didnt know about the effects those things had on the boost levels. There's plenty of cars running R-tech stage 2+ and I haven't heard any horror stories of them blowing a turbo on a hot day so hopefully mine will survive :driver:. If it does break my K03 then maybe I'll have to just get a K04 :evilgrin:
-
A well calibrated map from Niki will no doubt be correctly calibrated to account for changes in temperature (IAT) and atmosphecric pressure
-
mine was mapped in summer
so prob even more bhp now in the cold ! lol
certainly feels more bhp in this weather

Thanks for the clarifications, Nikki certainly seems to be the guru from the various posts I've read on the web.

yes true i do try tho lol
-
Some serious figures in here! Very surprised but excited lol!
Sorry to hijack the thread but thought I would post as I am looking to do the same thing. I had my Mk5 GTI mapped by Niki in the summer and made 255bhp 316ft/lbs with just the 2 cats removed from the exhaust. Now I want more power but I am so torn between going stage2+ on the k03 or stage2+ on the k04!
Would be great to hear your views and opinions guys!
Thanks in advance :happy2:
-
^^^^ Given a choice, there's only one......... K04......next!!
-
K04 is just better :laugh:
If you want serious power then K04 is the way to go, such a great turbo for response & power band :happy2:
As I've said in other posts too, it's better for traction as the power delivery is typically smoother and further up the rev range whereas K03 spools almost like a diesel turbo with huge wad of torque low down making it easy for the wheels to break traction
-
Im currently running a stage 1 r tech and cannot wait to go stage 2+.....its an addictive game! :drool:
-
I can't wait to get down to R Tech on Wednesday. I've no idea what figures to expect, but I'm looking for more midrange torque. I've had a custom map on for 70,000 miles now and it's always had oodles of top end power and really takes off at 4,000rpm, but it'd be great to see that power come in at 3,000rpm or lower if possible.
I'm running: ITG Maxogen G60, Loba HPFP, Forge Twintercooler, Longlife custom TBE w/200 cell sports cat. R8 coilpacks.
I must say, even though the car has been polybushed front and rear, so was stiff anyway, the recent introduction of 034Motorsport Density Line engine/ transmission mounts and Vibratechnics subframe mount/dogbone bush has made such a difference to the power delivery. There is literally no movement, the car handles on rails. In a way the power delivery feels a little less exuberant, because it's smoother, it's not, but it feels like it. I also noticed being able to get on the power quicker after fitting the uprated Neuspeed crankshaft pulley.

2+ is great, turbo response is fantastic, more like a TDI and a typical petrol turbo - any revs and gear and it just picks up and goes. Don't expect your clutch to last though
-
Loved my gti when it was ko3 stage 2+ it made 281 bhp and 356 lbft it was a quick car at that level of tune

Well had a bit of a gutting time at R-Tech, never thought I'd say that and it's nothing to do with R-Tech more having the wrong set up and apparently not having a 'healthy car', which I wish I'd known before I went to be honest. :rolleye:
Apparently the Forge Twintercooler is way to big a setup for a Ko3 turbo and thus I'm losing loads of torque, especially low down. So Niki has advised me to switch to an uprated S3 IC which should realise 30-40lbft of torque. Again wish I'd know this before the 500 mile round trip. I was honest with my mods prior to my visit, promise! :phew:
Also the engine is overly rattly on the cam side, which I knew, but had always been advised wasn't an issue as the car ran will, Niki tells me it's time to change the cam chain et al and others have confirmed that a bad cam chain/adjuster can cause engine inefficency.
Further still Niki explained how my previous mapper had loaded the fuel ratio up so much in my tune, that the engine had likely been washing itself with fuel (apparently the fuel smell from the oil stung his eyes) as a consequence the turbo had been running really hot. Did I mention that there's a crack in the turbo housing :pomppomp:
Car made 284bhp and 307lbft. Niki tells me with all the hardware I've got, that's 50-60lbft shy of where the car should be at. To be honest I wasn't expecting those sort of gains, I guess in my head I'd anticipated something like 290/330 or 280/340 etc.
I love my car and round the Devon twisties it's exactly what I need, quick spool up, just enough power for a fwd and maximum driveabilty from 30-90mph. So I've decided to go ahead with the cam chain replacement, sorting an uprated Darkside S3 IC and will most likely replace the turbo. I think AET sell the ko3 for £350, if not VW are £519.
-
At least you know where you're at with the engine, if you look at the positive side. If you hadn't taken it to R-Tech you might have carried on blissfully unaware of the issues and ended up with bigger problems down the line.
Interesting what you say about the intercooler. It's on my to-do list to uprate mine and up to now I haven't been sure of the best solution for a k03 - so it's good to know that the S3 one is a good choice.
Anything in the 280s is good peak power on a k03, but like you say you should be closer to 350lb/ft. It's the low and mid range torque that makes a k03 so good to drive.
Best of luck getting it all sorted mate.
-
I agree, the top end power means f*ck all to me. So the car accelerates great from 90-130mph, but when is that ever useful. The best apart about the ko3 is what I'm missing, low down torque. You're right though, I have to look on the brightside. Hopefully others will realise the Forge Twintercooler is not the way to go, mind you if anyone with a ko4 (which apparently is the only set up the IC is really useful for) is looking for a Twintercooler you can have mine!
-
I have put my low torque output down to intercooler also,as besides that, there is no other real reason I can come to given the hardware fitted, unless my engine isn't really healthy.
Just for info, I am running an airtec cooler and I only seen 288 ft lbs on revo 2+, and then 298 on apr 2+. Both agents know what has been fitted/changed, so effectively should have made good overall figures but came shy.
I have lined up a swap plus cash my way for a direct swap of an s3 cooler for my airtec, and we will swap over at the same time, then we shall see how it goes
-
Are these aftermarket coolers simply too big for the k03 then? Is it boost drop, or is that a different thing?
-
It's a spool and low down torque issue. The extra volume that has to be filled with an OEM IC and Forge Twintercooler before pressures goes into the inlet manifold delays boost and creates lag. They're simply too big for ko3 setups. Any ko3, regardless of hardware should at max capacity be running only an S3 IC or uprated version of the S3 IC anything else is counter productive and takes that low to mid range driveabilty away that the ko3 is renowned for.
-
From what research I've done and what Niki said, installing the uprated S3 IC over my OEM+Forge Twintercooler should realise a minimum of 30-40 lbft and maybe even some bhp, although the concensus seems to be split on that one. The upside to this ballache is not having to have the new IC mapped in. If I don't see some sizeable gains from the new IC, the new turbo and the cam chain replacement, I'll shut brick and buy a Fiat
-
I'm just unsure if the airtec I have on is the reason for mine being low, but I keep hearing that s3 coolers are more suited to the ko3 than a larger one.
Mine could be something else, but I don't have anyone who can guide me to start ticking things off in the way of logging etc
-
I'm afraid I can't help you with regards to the IC. I mean plugs, packs, DV, blocked cat, dirty CAI, knackered turbo vanes, rubbish or old engine oil, dirty fuel filter. It all contributes I guess.
-
For sure it seems too big an IC will cause big losses in torque, especially low down and also to a lesser extent bhp. I don't know how much of a bigger volume the Airtec is, I know the Twintercooler system is pretty much the biggest cc of all the setups, ao I can certainly attribute a lot of my losses to that, or so I've been told. Like I said, if I don't see any noticeable gains from S3 IC and a new turbo, then I'll be at a dead loss as to why my ko3 is 10-15bhp & 50lbft under par for its stage.
-
I've looked after my car so well, well everything that was under my control. Oil changes every 3k, only the best oil, new filters, new plugs, general health checks, new fuel filters every 15k, engine flush every 6k, inlet valves and injectors cleaned every 25k as well as IMV cleaner every 15k, cam follower every 10k, gearbox oil every 35k, six monthly checks for moisture content in brake/clutch fluid and replaced if necessary. I've literally done everything and more one could do. To hear Niki say he didn't think it was a healthy car and to give me a 'to do' list literally broke my heart. He didn't want to say it, poor sod, I had to say to him, 'spit it out, it's fine'.
-
Well, all last year prior to testing and mapping, new rev g dv, genuine r8 coil packs, ngk iridium plugs, new revo intake, new powervalve tbe with 200 cel cat, fresh oil change after just been changed a month and half prior also, new fuel filter, new airtec cooler, new dsg mechatronics unit, new cam follower along with new autotec hpfp internals!
I think I'm going to change the intercooler and add a turn or two pre-load on the turbo actuator, as the apr agent reckons that could be the reason

I am the same with mine, hence why I am a little frustrated with the outcome. Makes it harder trying to tell the wife the car needs other bits to release the real potential of it, she doesn't understand what I am going to gain from it!
-
No for sure. The sh*t I have to come up with when parts turn up haha! Niki was most unimpressed the my actuator had been tweaked, said there's no need for it, I didn't even know it had! Sounds like we're in the same boat, if I was you, I'd start with the IC then possibly get someone to inspect the turbo with a boreascope!
-
Has yours been adjusted before? What did he say regarding it? Replace the turbo if it's getting weak or actuator?
-
My turbo has a crack in the housing and was coated with oil. So it's a straight replacement. Actuators rarely go from what I've been told. You could see if it's sticking, but I doubt it.
-
It's definitely not sticking, but from what I hear, the actuators on the ko3's do get weak over time and rather than replacing, I have been advised that if adding a couple of turns of pre-load cures it, then I really should replace the actuator, but I could run the car with it for a while
-
Well I think you probably know more than me. Worth shot isn't it! I know my turbo is 100k old, it's got a crack in it, Niki said it was covered in oil, so it stands to reason it's not very efficient. So IC and turbo are my first ports of call to remedy my shortfall in power!
-
Your still produced a fair amount more than mine, bhp wise that is. Did you say yours has been run mapped for 70k? Is that possibly the reason behind your turbo splitting? Mine has been standard with a very documented history for 70k before any modifications....
-
Yeah it could very well be. It's been running fuel heavy for 70k too, so most likely been washing itself with fuel, it's burned sh*t loads of oil so I'm guessing that's a good shout.
-
I think I'll adjust mine up a tad and change the cooler over and get it back on the rollers and see how's she does then, before I go down the line of another file
