hi all just some things i would like to get info on.

i have a 1.8 turbo engine code is agu on a 98-99 plate, cable thottle body.
i have just gota second hand ko3s and kinda finding it hard to understand
that every body is saying custom remaps.

so here is the thing?? why cant i just get an 180hp oem map that uses the
k03s turbo and have that fitted at less cost than a custom map????


as for solder in chips if they are generic they must be based on some thing

ie 1.8 turbo using a k03s late model???


so what i am looking for is a mild tune using the k03s turbo still getting good mpg but with more guts if
needed, so any help would be really great.


on another thing i live in great yarmouth, norfolk and finding local tuners is not so easy.


any one local that can help pm me please.

welcome.

cars that use the later ko3s turbo have different ecus to your earlier one, with different features etc. it could be swapped onto your car but then its alot of hassle for V little gain. they are also a slightly different engine (small port to your large port) so im not sure how that would work.

in terms of remaps, provided you fit your new turbo, they dont use a chip as such, the car is plugged in and mapped that way.

my advise would be to fit the turbo and have it mapped to your specifications/needs. visit a reputable tuner such as r-tech, badger 5 or unicorn developments and they can have your car running perfect for in some cases, a v good price.

as for returning good mpg, you will only get so much out of a 1.8t, they arent great by todays modern standards but they arent half bad. and, some, in fact most people report better mpg after a remap. remember, the engine is working alot more efficiently.

hope i've helped

Hi dude, welcome to asn. Well id check the stickies 1st but since im here :).

First off good call on the ko3s, that will bolt strait on, and a stage 1 map will see you 210-20bhp, and thats as mild as it gets really, i suppose you could get an eco map, but the stage1 will see you better mpg anyway. As for the ecu swap itd probly not work as you have an agu with cable throttle and all ko3s are DBW. Not to mention a whole load of diffrences, injectors,maf,o2 secors ect ect. As for a reputable tuner to map your car, thers r-tech that do a home service but i think theyd charge for the milage and badger5 bristol way. There are loads more but everyone always drums on about these guys, so they must be the shiz. As for keeping everything reliable get a fmic, a silicone tip and either mod your oe air box or buy a cone induction kit... And i think thats about it without going into hybrids and ko4 conversions lol.

Good luck with watever you decide

better mpg that sounds away of getting the cash from the wife lol. didnt kinda expect 210-220 from stage 1 map
thought i would have to get stage 2.

as for fmic is it realy needed if i moved the side mounted to front wont that do??? or pos duct from
front grills to force air over side intercooler by some meens ???

feel a project coming at work with cooler shroud!!!!

so keep it going info is great.

its the volume and efficiency of the standard side mount that becomes a problem. well, not a problem as such, but with a fmic you'l find more power througout the rev range, whereas with the sidemount, power will be effected by the extra heat.
mapped sensibly monitoring all these things and you wont NEED one.

Nah mate the smic wont fit at the front and plenty of air gets to it, its just poo lol yeh the ko3s is what will get you that 210bhp, tbf a down pipe and decat would see you to the 225bhp mark but you need a fmic to keep it a consistant and reliable, as heat kills power.id read a few build threads, prawns and customboy are two that spring to mind(theres loads more tho) also check the stickies out, loads of info in them.

i'm running a ko3s with a standard intercooler and i will be fitting a front mount as soon as the funds are available cos the car drives a lot better on a cold night. defo get a 3"downpipe and decat but it does pop and bang a lot once u do lol
 
i got turbo from ebay and asked the guy to tell me the id numbers on plate and turbo casing, there is still a chance its not
but hay. i have turbo i can play with then.

as for engine code its agu. and yes i found out today it can be mapped though the port but i would love to find some one that has
a map on disc that could help out hint hint.

£300 notes for 30 min work from norfolk tuners seems very high if you look at the time it takes and how many times the data can be used
i understand money and busness but my god.

thats more than a prostitute would charge an hour (not that i have ever)

norfolkaudi.
 
nope that costs extra thats just plug in and play price, if i added the k03s turbo that would cost more.

as thats custom, but as i see it its been done by so many it should be a standard remap file.

norfolkaudi
 
Ouch... thats alot!!
R tech remapped mine, but the dyno runs really helped! Not because i got to the actual gains, but they were able to see that my car wasn't running right. 110bhp out of the 150bhp quick change of MAFs and back to normal. Deffo look around for somewhere reputable and travelling that extra few miles may prove to be worth it...Good luck mate

thanks jay.

i have looked over car with vagcom and there are fults that are showing plus she has only done 63000
not bad for 13 year old and full service history.

and yes i think i will keep looking
 
Hi notfolkadui welcome to the best that Audi owners come to offer, well like u got the same engine and did a basic stage one with rtech (mobile mapping) only cost me £200 and changed my dv to a forge one and then a simple pipercross panel filter, but the bug hit me after that mate and wanted more so now I'm running a stage 2 ko3s turbo, cold air feed to airbox that's been drilled and smoothed also forge fmic fitted and 3" downpipe and decat and Scorpian exhaust, now running 222bhp and 250ftlb torque, stage 2 map was one by nick at rtech and car has never ran better they are well worth the 150 mile journey !! Now bug has bitten me harder and soon going to be fitting my k04 turbo with other bits and back to rtech again!! And like ur car mine has on,y covered now 86k with full Audi service but I got a need for speed ! But feel free to ask me anything and hopefully can steer u in the right direction !
 
so i am geing some place, some other things i need to ask guys. what other mods do i need to make, got turbo sorted got exharst
going to run standard intercooler for mo, but need list of parts for it to all work well.

not bothered about bling want to try and keep the look stock.

firstly if you're getting a ko3s turbo, you will need a custom map. generic stage 1/2 aren't designed for the turbo you put on, plus, every car is different no matter what, this is why a tuner that will map on a dyno and log etc is so important, afterall you want the car running just right. you will pay at the v least 250 for a map of this kind, 250 is VERY cheap from r-tech.

to accompany the turbo id advise a new silicone TIP (turbo intake pipe).
a new dump/diverter valve, forge 007p.
a performance filter of some kind, could be a panel replacement or large cone filter.
then anything else is an added bonus really, FMIC, 3 inch downpipe, decat. it all depends on your budget. the 3 i listed i would say are needed.

Whilst I agree with you Karl that it's the right way to do it, this isn't strictly true. The mods you listed that are needed are spot on though.

I used to run my K03s on a Stage 1 Revo with a manual boost controller. Revo didn't do a stage 2 for cable throttle cars so I just stuck with Stage 1.

The ME3.8 ECU on the AGU is daft as a brush. It has no MAP sensor has no idea if actual boost ever matches requested.

The fuelling on the AGU is primarily air flow driven, and so there aren't normally issues with running MBC control as long as you don't go daft. It does calculate boost using a calculation of airflow x throttle body angle so if you go over the top then it will be OK.

Highest airflow I saw out of that setup was 186 G/S which is a good whack of airflow, and the thing went so so well for what it was. That was running around or about 19 - 20 PSI boost (initially - fell off after that as K03s do).

So, my advise is don't expect to HAVE to pay for a custom map - IMO of course.

Also, easiest way to tell a K03S from a K03 is to count the compressor blades. 12 blades = K03. 8 Blades = K03S.

I gonna have to keep eye on this post as i have got an AGU lump too and looking for ideas for mine.

What sort of power will the standard clutch be able to handle before that will need to be uprated to?
Click to expand...

Stock clutch in good condition will be able to handle up to 300 bhp without any problem I would have thought.
 
whilst he could go for a stage 1 revo, they are a tad more expensive than even a custom map at r-tech. which is why i suggested them and that it would be better. as it seemed the OP was worried about cost.

its is kinda good that the ECU is that thick you can do that tho.

Absolutely, Revo 1 is about £400. Just saying that that was what I did, and seemed to work well.

Personally i wouldnt bother with Jabba Their mapping from cars i`ve spent time with is pretty naff and their figures need to be taken with a huge pinch of salt. They did a friends mk4 golf 1.8t, k03s and supporting mods of which they somehow said it made 260bhp on their rollers which i`ve never heard of a car make that before on his spec.

It blew up last year and had to put a new engine in it lol.

Ha its rare people ask about the clutch when remapping these days lol

As welly said the standard does the job, but are exspensive when they need a new flywheel! They say 2 clutchs before the flywheel needs changing on the 3rd.

I changed mine to a single mass flywheel setup. People report chatter and harsh biting point but mine has been ace,Its cheaper than a dual mass flywheel on its own aswel as a lovely and light clutch peddle, with better grunt off the mark.

Not to mention itl cope with over 260ftlb of torque, not that i have 260ftlb of torque to test it really lol

One of the best things iv done to the car by far.
 
i am glad this this going so well and got peeps interest, so i have worked out that there is some hipe
as to comp clutchs, but what i like is that you dont need to spend lots of cash to get results.

so to start.

1) i can use the oem intercooler but may need to work some kind of ducting to get more air to flow over it.
2)the agu engine ecu is very stupid but thats what makes it so great to tune and by rights easy for tuning files.
3)the clutch can be standard but would need ssf to work better
4)better dv forge and tip plus comp panel filter
5)sports exhaurst and poss de-cat????????
6)mcb would work better aswell.

have i missed any thing hmmmmmmmm.

thets try this, some guys are saying 3" all the way from header. but standard i think is 2"1/2
and reading from lots of sites from the all over the world would suggest thats fine.
and 3" would not give any extra benefits.

Now this is one for all of you.

de-cats and sports cats::: why cant we use a more open pore cat say from audi 2.8 and just bolt it on
or weld it higher to the header??????

1)oem cooler does the job. not amazingly, but does the job, any 'ducting' is more hassle than its worth tbh.
2)dumb ecu is good to an extent, in that as welly says, you could run a generic stage 1 map with your upgraded turbo
3)standard clutch is fine for most common applications. a v common upgrade is clutch and flywheel off a vr6 golf, although im not entirely sure what exact parts they are, hopefully someone else can help with that.
4) tip, filter, dv. needed to help the car breathe better with its new turbo, and also to staop cavitation of the tip which is common on mapped cars. dv for reliability and prevent boost problems
5)IF you have a friendly MOT man, go decat, if you dont get a sportscat. welding/bolting in a cat off a standard car there is v little benefit, and v little to say it will pass. sportscats are tested, and work.
6)mbc to cap any intitial boost and subsequently torque spikes (these are baaaad!) if you decide to run your ko3s without a custom map to suit it.
 
hi just to update, the turbo came friday and i stated to take it apart, did find there is slight bend in the 4 mm shaft.

but to be honest £72 for a gen k03s is not that bad even if i replace shaft and reseal set.

can i replace with k04 shaft and bearing in k03s !!!!!!

Hi dude, most people(including myself) have a limited knowledge of hybrid setups, so best thing to do is search for a guy called beachbuggy on here, his got a really good thread about hybrids, but ill share some of the info iv learnt from the people on here lol basically there are diffrent degrees of modification that you can do, i.e the impeller and expeller and turbo housings can either be uprated or modified. Also beachbuggy will make you a hybrid for a very reasonable price. Only problem is that with a hybrid youl have to change all sorts to get the best from the power. As said before that the agu has a stupid brain, unless you jump to a ko4 conversion, as that is easier to map a hybrid on a agu(so iv heard), ko3 hybrids are also very spikey in torque delivery so youl have to take uprated rods into consideration.
