My mk4 golf has already got a stage 1 map from r tech but I was wondering what else I can do to get better performance , everything else is standard except the 007p
Recommended air filters ?
Plus when I go 4 a stage 2 in summer what else would I need to change so the car can handle the power better

How deep are your pockets and what power are you after?
-
Bout 230 bhp and il be happy
Currently running 185
Pockets are alright :wink:
-
230 can be seen with a k03s so not to much money :smiley:

From R-Tech:
Stage2 Tuning 225-240 BHP 250-270 LBFT = £290
For stage 2 tuning you will need:
1. Good quality cold air induction kit or Panel filter
2. Full turbo back exhaust with 100cell or de cat at least 2.5” bore+
3. Front mount intercooler with the boost pipes 2.5” or bigger. Not Side mount
4. Turbo intake pipe (TIP) Not cheap small bore ebays pipes
5. Forge 007p or OEM ‘N’ Revision diverter valve
6. N249 bypass
7. Decent strong actuator Pressure is key to the higher numbers, an actuator with 100+k on it will not make the higher stage2 numbers due to the spring getting weak, where a new oem actuator will do 250+bhp.
8. Cars with high miles tend to find there original fuel pumps cannot flow or keep up when trying to run stage 2 power, so again might be worth looking at a new oem pump.
9. Use 3bar fuel reg not a 4bar which kills pumps, if you want more fuel head room then fit TT/LCR 380cc injectors.
As for other mods, they aren't essential really but a spring/shock kit or coilovers will help. 312mm front brake conversions can be had cheaply, front and rear arb's make a huge improvement. There's lots that can be done.

Well these are my plans b4 the stage 2
Ko3s
Induction kit
Fmic
Milltek turbo back
And probably purchase another 007p as I dnt think mine is any good lol

This is the info I need ! Thanks man :smiley:
Any recommended induction kits?
Fmic ?
I heard the n249 bypass can't be done on a agu engine ?

I've got more info on an email about induction kits, I'll put it up as soon as the Mrs gets off Skype :rolleyes:

For the best result stage 2 and above you will need the best flowing
hardware to get the number, a lot of cheap and branded kits are not upto the
job to give the best results.
INDUCTION KITS/ AIR FILTERS
For induction kit we had to design our own cold air kit as non of the kits
on the market could flow decent air and stay cool, The R-Tech RAM-CAI
induction kit is only £120 fitted and has proven to flow for over 650bhp.
FMICs / Intercoolers
The are many fmic options on the market which range from £90 for universal
setups to £700 branded units, the price don’t mean it’s the best flowing /
cooling setup for your application. The £700 kits tend to be made of best
quality materials and to fit easy, the £90 kits poor quality and poor
fitting, lots of chopping and cutting needed. The best proven all around
fmic is the “Wellycooler” setup, this has proven to us over the past years
to give the best cooling and flow at all stages of tune, we are running them
at 450+bhp on car with GT turbo. The Wellycooler kit is basically a Toyo
2.5” core with ASH hoses pipes. It costs around £220 for the materials.
For more information on the wellycooler setups just search google and have a
quick read up.
We can provide a custom 2.5” alloy welded hard pipe custom fmic setup
supplied and fitted for £470 all inc. It’s the wellycooler without all the
joins.
Exhausts and decats
Again with exhaust systems there are 1000s of options, but basically sub
350bhp all you need is a decent flowing 2.5” pipe work exhaust with decent
bends which don’t cause a bottle neck in flow. Milltek is the best direct
bolt on option for a full turbo back system. You can find on ebay decent
3” downpipe and decat setup for around £80 which are good enough for 320bhp
and an easy fit to any other cat back system.
Going 3” exhaust on a k03 is over kill and will knock on the rear beam.
DUMP VALVES
Only proven DVs to work well with the 1.8T are the Forge 007p or 008 DV with
the new pistion design. But the best working DV is the new stock factory
plastic DV, the 710n or 710P from an Audi TT part number from main dealers
06A 145 710 P £35
TIPS / TURBO INTAKE PIPES
Again many options around ranging from £50 to £140, the cheap ebay tips are
crap full stop, the bodies on them are smaller than the stock ones, they
flow really bad and make less power then the stock tips. Forge sell the
upgrade tip which flow better than the stock tips upto around 240bhp these
are around £140. The best flowing tip for the k03 turbos is the 70mm
Supersize tips which have proven to flow over 300bhp on the K300 hybrid
turbos. R-Tech do there own brand 70mm supersize tip for £110 fitted, SFS
also sell them.
Exhaust manifolds
If your looking for the very best from your setup you might want to port the
exhaust manifold collector, this can aid flow for another 10-12bhp at the
higher end of the rpm scale. If your good at DIY its going to cost you
nothing, but if you pay someone your looking at around £120 labour.

I stubbled across this for a air filter cheap as chips http://www.audi-sport.net/vb/a3-s3-forum-8l-chassis/118673-benjamins-s2000-air-filter-mod.html i dont know if this fits the mk4 golf but its worth looking at

I'm running an S2000 filter with heat shield, you need a silicone reducer to fit onto a MK4.

would a decent panel filter not be ok :undecided:
Regarding the panel filter
Would a piper cross be okay
There about £32 on eBay
What would u recommend ?
