Thanks JV.
So, it all began when my mk3 became impracticle for the family after buying a lowering kit that said in the ad 40mm but ended up more 60-80mm... (too much time and money to change back)
after taking a liking to VWs i thought i would look for an affordable mk4, but it had to have some grunt.
then i spotted this 99 AGU 1.8T in red which i thought was a good price.
here is a pic of what she looked like before i bought her.

within a week of owning the car i found that the springs had snapped on the front, so my first mod was to get her lowered a little, so i went and bought a set of jamex -35mm springs for £52 on ebay.
i got these fitted as soon as they arrived as i didnt have a car for work, the ride isnt the best as i havent upgraded the shocks yet. its on my list bit other things need doing first. :cool:
the walnut sh!t on the dash really didnt take to my fancy so it had to go.. i found a cheap solution in a local motor factors.. chavvy maybe but i like the look.. i went for iron on carbon fibre stuff and i think it looks quite sporty. (no pics just yet, will get some soon).
after reading bad things about the standard DV i decided an upgrade was a must. Forge was a bit pricey for me so i found this R-spec one on ebay for a little bit less, £50 for the DV and i bought some nice silicone vac hose to fit it with, and i replace the pipe on the FPR while i was there.
to compliment the new DV i added a pipercross panel filter and smoothed the airbox whilst chucking the restrictive induction pipe and replacing it with a larger diameter cold air feed (works in the same way as the DSG but at the fraction of the cost)
more later! :smiley:
-
Got an R-tech remap booked for next monday.. really cant wait for this one. cant afford a fmic just yet but it will be one of my next mods. :cool:
its such a nice day i might just paint my montreal`s with a bit of gloss black..
-
well i did say i was going to gloss black my montreal`s so i took a little inspiration.. it may be a little marmite for some of you but i like it.. :smiley: i am going for a red and black sort of them so will look really cool once i have done the other things..
(http://i45.photobucket.com/albums/f82/citroenaxgtr/PDR_0002.jpg)
also the other day i tinted my headlamps, but not the joey mod way, i did it my way!! :grin: although i`m not too happy with the finish i may just scrap it and do the joey mod or redo what i have done.
:cool:
(http://i45.photobucket.com/albums/f82/citroenaxgtr/PDR_0003.jpg)
my light smoke tints should be in the post as we speak so they will compliment the mods i have already done so im excited about that and my remap is booked in.
black side repeaters are on my to do list
the spending has commenced.. :tongue:
-
well got my tints and side repeaters and fitted them today.. one word, have a second pair of hands when doing the tints.
i had to struggle on my own with the tints and it didnt turn out perfect but it looks o.k..
its not too dark and although they`re on the front (fingers crossed) the cops should leave me alone..

R-tech are on their way as i type :smiley: just twiddling my thumbs now in an anxious wait :tongue:
hopefuly now the car should have some chug instead of feeling so flat.. :evil:
-
ben from R-tech has been and gone.. :smiley: smiles all round :evil:
what a difference..
-
i think it`s about time i updated this... i have done loads since my last post just never been arsed about showing it..
i will take some pics tomorrow and update my mods done and to do list..

-
this is how the car currently stands, ..... on axle stands :grin:
(http://i45.photobucket.com/albums/f82/citroenaxgtr/100_0137.jpg)
underneath the car, i decided to brush on some red hammerite to some of the parts that were showing some surface rust.
i brushed them down with a wire brush, used a bit of degreaser and painted on one coat... this was last night after the first coat..
(http://i45.photobucket.com/albums/f82/citroenaxgtr/100_0136.jpg)
here is a pic of my DIY style cold air intake pipe... no frills style :grin:
(http://i45.photobucket.com/albums/f82/citroenaxgtr/100_0139.jpg)
(http://i45.photobucket.com/albums/f82/citroenaxgtr/100_0140.jpg)
a pic of my shabby cobra sprints in my stripped interior, could do with a vacuum i suppose.
(http://i45.photobucket.com/albums/f82/citroenaxgtr/100_0130.jpg)
as you can probably see, i am not taking the cosmeticly pleasing aproach. my idea is to use this car for track days when i feel its ready, far from ready yet. i will be using the car for the road too..
next plan is a basic car pc :smiley:
-
i am currently in the middle of gathering all the parts needed to gain some more power, i already have some calibra injectors and vr6 mass air flow housing, i now need a bigger turbo not sure exactly which route to go, wether it be k03-k04-023 hybrid or k04-001/023 hybrid.. let see how nick at r-tech does with his k03/023 hybrid first.
-
o.k, not wasting anytime waiting for others results :rolleyes: lol :grin: so i have bit the bullet and bought a k04-023 compressor wheel which the postman so kindly delivered this morning and have a rebuild kit. also have a dead k04-023 which i can steal the cold housing from.
guess what i will be doing the weekend.. :smiley: looks like a turbo rebuild/hybrid to me.. :evil:
i have also bought a used OMP steering wheel, i am waiting on a boss which i bought from ebay but the seller seems to be deaf.. bought over a week ago and no response to my messages.. :angry:
so, only one more thing i need to get this on the road, thats a tyre... just one tyre and its time for an mot..
-
so, i have made a start at hybriding the k03s to k03/k04-023. i have taken the turbo off the car and started to dismantle, some of the hotside bolts are a little stubborn and it seems a 10mm spanner is a tad loose on them, not sure if there is an imperial spanner that will fit nice?.. i have got the coldside housing off and chopped off the outlet elbow so it can be welded to the k04 housing this will make it an almost OEM fit (apart from the TIP inlet). in the pic also shows the homebrew forge actuator trial fitted... :cool:

(http://i45.photobucket.com/albums/f82/citroenaxgtr/Pic_1211_002.jpg)
-
just finished rebuilding and hybriding my k03s chra to k03/k04-023, going to find prices now for chra balancing, i really cant wait to get this bolted up now and see what it can do :evil:
(http://i45.photobucket.com/albums/f82/citroenaxgtr/Pic_1212_001.jpg)
i am quite supprised actually at the condition of the k03s i took off, considering i bought it as spares or repairs, had a quick look at it myself and deemed it as fair enough to use, i had my fun out of it and when i took it off it still didnt seem too bad. :smiley:
-
alrighty, just a quick update. my chra assembly is being balanced as we speak. i have my omp steering wheel fitted but the original boss i had didnt fit as the ebay seller decribed it as fitting the mk4 platform but was infact from a mk3.. he has gone silent. (is actually a member on here and was selling loads of mk3 parts) beware! i will get my snail housing welded up next week and then i will be putting things all back together. i am tempted to use a local tuner who appears to have a good reputation so will see.
-
my k03/k04 hybrid is now built :smiley: ive had it balanced and welded and i reassembled it earlier.. will be putting back on the car the weekend hopefuly.
-
Woww I need to come up and have a look at this.
Maybe you could sort me out with similar if I supply everything you need and money :grin:
I want more power from mine, its just not fast enough no more :embarassed:

just a quick update, the golf is going back on the road within the next two weeks. that hybrid turbo was a failure so another plan has been devised. :wink:
-
what can i say about my golf for the last 18 months or so?.
not been able to spend any money on it really so it had been sitting in the back garden for a while.
my 6y/o autistic son had some fun with it, he managed to fry the cells in the battery by leaving the hazards etc on, and cover the interior in grass. he got scratches on the roof and bonnet from using the windscreen as a slide. so its been quite depressing really.. :cry:
it`s going to need a respray as it was desperate for one before it went off the road, but i think i`d rather put my money on tuning than cosmetics for the moment.
i`m not sure wether i should even do a matte or satin job on it for a cheap effect.. what are your opinions on that?.
i don`t really want to spend much on appearence but from the outside it looks tatty..
-
i thought i would take some pics to show the progress, or lack of.
in desperate need of a clean and respray.. ah, f**k the respray..
the bucket seats are quite shabby and are n home made mounts made from the old seats..
the next plan is get new seats, mount them on solid rails and get some 4/5 point harness`s :smug:
a roll cage would be nice, but £800 is out of my budget.. perhaps big brakes next. :smiley:

she passed her mot this afternoon, tax in the morning and all good to go :smiley:
the drive back from the mot was interesting with the new turbo, boosting like mad. i think i need to get it to r-tech as soon as i get some money to do it.
she feel`s so much tighter without all that interior though, the difference is immense. might have something to do with the fact ive driven a renault scenic bus for the last two years giving me a false impression. :whistle:
still, it really is planted to the tarmac.
-
weaker forge actuator spring ordered and should be here in the morning. currently fitted with red spring and it`s overboosting like a mofo. :whistle:
-
Over boosting problem found and fixed, turned out to be a mis-seated diaphragm.
also swapped red spring for a yellow spring.
and now charcoal Evap canister deleted :smiley:
-
walbro intank pump is giving a bit of starvation when low on fuel so it`s now being scrapped in favour for a standard intank lift pump, a surge tank / swirl pot and a high pressure in line fuel pump.
i dont see the point in paying silly money for a second hand LCR pump and also i like to have a go and installing something of my own. will see how it goes :smiley:
-
Today i went about re-routing my brake vac pipework to neaten things up a little. While I was at it I got rid of most of the blue silicone vac pipe as I could as I thought it just looked untidy.
I also extended my n75 loom with a Ev1 pigtail, I was going to relocate it completly but thought it was neat enough left in the TIP
Now that the evap canister has been deleted I had a spare port which was on the offside of the car which meant I had a lot shorter route I could take to the brake servo.
I went about ripping the anaconda pipe out and saved the check valve.
I decided to use 7mm silicone as I found the 10mm stuff was colapsing slightly under vac.
It`s not the neatest of engine bays, but work is in progress :tongue: :lipsrsealed:

I found that the golf was cutting back on power at about 4.5k rpm for some reason, it had me scratching my head for a while as it was fine before taking it off the road.
my first thoughts were the turbo, originally the forge actuator diaphragm was leaking causing the turbo to overboost and the ecu cut power really early.
i fixed that and still had issues at about 4.5k so i did some logs which shows there was a lot of knock, particulaly worse on cylinder 3. this let me to believe that it was an EGT related issue.
(http://i45.photobucket.com/albums/f82/citroenaxgtr/log1.png) (http://s45.photobucket.com/user/citroenaxgtr/media/log1.png.html)
calculating the mafs grams/second worked out it was pushing 205 bhp which was about 19bhp down from my RR results 224bhp.
I realised that the exhaust was restricted and i was running a stage 2 map. I had my standard cat fitted for mot reasons and soon realised that this was causing the restriction. So, i spent half an hour under the car and swapped over the cat for a decat and then did two more logs but this time i did them seperatly to give a more accurate reading.
note the mafs peak g/s in the plot below, if you calculated it to estimated bhp it works out to about 235bhp.
it just goes to show how massively restricted the standard cat actually is. there is a 30bhp difference without any tuning involved, apart from the newer turbo which hasnt yet been dailled in.
(http://i45.photobucket.com/albums/f82/citroenaxgtr/maflog1.png) (http://s45.photobucket.com/user/citroenaxgtr/media/maflog1.png.html)
below is a log of the knock retard channels, you can now see that the knock has gone :smiley:
(http://i45.photobucket.com/albums/f82/citroenaxgtr/knocklog1.png) (http://s45.photobucket.com/user/citroenaxgtr/media/knocklog1.png.html)
the car is now driving freely to redline, though i never really drive to redline as i find there is never any need to as most of the power is mid range. :smiley:
-
Fitted a leon cupra R fuel pump today. most of the way now to getting good power.
i`m undecided on going the water meth route though :undecided: its alot of money, i know it`s supposed to be magic but the cheapest i`ve seen the kits go for is about £250 :cry: .
Next on the list now is to upgrade the intercooler pipework.
-
today`s doings.... :whistle: excuse the bad picture, its my trusty old iphone 3gs :drool:
(http://i45.photobucket.com/albums/f82/citroenaxgtr/null-3.jpg) (http://s45.photobucket.com/user/citroenaxgtr/media/null-3.jpg.html)
I managed to flash a stock AGU file onto an AGN ecu, they are the same breed ecu :smiley:
this was a little experiment on a spare ecu i bought to have a play with. start off small and maybe one day i will be able to base map my own car with the right tools.
next toy on the list (after my new intercooler pipes) will be a wideband controller and guage kit. :smiley:
-
i`ve not been online now for a couple of weeks so i thought i would let you know what i have been up to.
ive noticed i have been getting boost spikes as i now i have a bigger turbo and my n75 is not mapped to control it. i set about getting a manual boost controller to control the boost and just leave the n75 connected electrically. this works great and set at about 17psi it just holds.
there is a downside though, as this is a bleed type valve, when off throttle, it bleeds and bypasses a small amount of air back to the manifold and causes high idle for a few seconds until the ecu corrects it.
so, i`m thinking of getting a ball and spring type valve and running it parallel with the N75 untill i can afford to take it for custom mapping.
another thing i experimented with was trying my vr6 maf and calibra injectors and these are the results.
Vr6 maf, calibra injectors, 3 bar fpr - no run
vr6 maf, stock injectors, 4 bar fpr - ran pretty smooth but no power
stock maf, calibra injectors, 3 bar fpr - no run
which ever combination with the calibra injectors i would get no start. i think the injectors are f**ked!
on a plus note, i have just gone and bought a set of saab red injectors so more power should be achieved.

another overdue update.
the postman came yesterday and popped something through the door..
(http://i45.photobucket.com/albums/f82/citroenaxgtr/null_zpsbae59160.jpg) (http://s45.photobucket.com/user/citroenaxgtr/media/null_zpsbae59160.jpg.html)
I`m now on the lookout for a progressive controller and nitrous bottle :wink:
nothing has really been done to the car since. :tongue:
-
today i made a nice little bracket to mount the solenoids to the inner wing where the charcoal evap canister used to live..
i`m hoping to make this a neat little install.
my bosch saab turbo reds and vr6 maf housing might be up for sale if i get all this running sweet. there wont be any need for them.. :grin:
-
o.k, so I managed to find a suitable bottle for holding nitrous oxide. an ex co2 fire extinguisher capable of holding around 15lb of nitrous all tested and legal and for the bargain price of £5.
So, I spent about 3 hours yesterday trying to get it polished.
(http://i45.photobucket.com/albums/f82/citroenaxgtr/null_zps17bdea4d.jpg) (http://s45.photobucket.com/user/citroenaxgtr/media/null_zps17bdea4d.jpg.html)

As you can see, its far from finished, the finest grit I had was 120 so had to stop there for now.
next I will be looking for some braided line as a nitrous feed from the bottle to the solenoid, I would use nylon but the price for the "proper" stuff is disgusting so gonna look in pirtek tomorrow to price it up.
-
had another go tonight at polishing the nitrous bottle, I got loads of dust all over the kitchen and the missus aint very please. BUT, I think tonights efforts were worth it. not perfect but the best I think I could get it for now. I could have done with a bit more sanding in previous stages.
here are the results.
