Ok I have £1000 i want to spend on mods for my octy mk2 vRS.

At the moment it is completely standard, and I want to spend the 1k getting as fast as I can for that cash.

Do I go for a Stage 1 remap and a Miltek exhaust?

Do I go for a stage 1 remap with a Forge DV, Panel filter, 4bar fuel pressure regulator(no idea what one of these is)

Or do i just go for a Stage 1 and a Forge DV (as i hear the standard ones split?) and save the rest?

or Do i do a stage 2 + something ? (remember 1k limit)

Or any varient of the above combinations or something completely different?

your help in this matter will be apreciated

Thanks In Advance

Pete.

How about a compromise of straight line speed and handling - Stage 1 remap and Koni FSDs and lower springs?

I'd go for...

Remap, forge DV and evoms intake

Eibach Anti Roll bars (front and rear).

If that comes to more than 1k, ditch the evoms for now.

Hope that helps,

Lee

Does the evoms make a big difference? Much more then a K&N Panel filter?

With a panel filter I git a gain of 1bhp.

Im unsure of what I got with the Evoms as I had other bits done at the same time but I have a good source that reckons on 5-8bhp gain being very realistic for the evoms.

Lee

you dont need the forge DV, just go for the new D revision DV. its loads better than the original, still OEM and alot cheaper, and doesnt need servicing.

My money would be

Stage 1 remap- £350-£500

eibach ARBs-£250

Whiteline Anti Lift Kit £130

D revision DV £40 (I actually wouldnt bother replacing it until it does go, mine lasted 8k with remap before going)

leavinbg yourself £100 for fitting etc

Remap, Evoms and ARB's

I got asked a few weeks back a similar question in a PM and answered as below, hopefully may be of some help to you ............

"Ok I'll try and answer your questions as best I can but these are MY opnions on what I would do starting with:-

minimum revo Stage one

I have seen the results of so many remaps on 2.0 TFSI's (hundreds of RR runs) and am convinced that REVO is the best way to go, especially if you have plans to upgrade to Stage II and beyond. Stage one is fantastic, makes a huge difference over standard and I would not hesitate recomending you going ahead straight away with this mod.

Don't forget to fit a Torque Arm Insert (Neuspeed do one), relatively cheap but it does help keeping engine movement down to a minimum.

To enhance the capabilities of Stage I further then deffinately change the air filter to a K&N, Jettex etc. (they're all pretty much the same imo) or if you feel like splashing the cash the the Carbonio is a very nice bit of kit and easy to fit but not everyone agrees there is any significant improvement over just changing the filter however I liked it to the extent that I very nearly went back to it from the EVOMS purely because I prefred the sound from it!

Assuming you are buying a second hand car I'd also change the DV to the latest VAG revision or fit the Forge aftermarket one.

If you don't intend on going further than stage I then I'd also consider Bluefin, but it is more restrictive and not ideal for future modding.

if i have enough money option - Revo Stage 2

Going to Stage II is a diffrent ball game altogether and this is where things start to get expensive for apparantly little gain but I'll try and summarise as best I can. These are the options I would fit and in the order I'd fit them:-

EVOMS intake will give you noticable increase in power, up around 15bhp over a standard OEM panel filter or around 8-10bhp over an aftermarktet panel filter such as a K&N. I can't recomend any other intakes but tbh the EVOMS is widely regarded as the best on the market.

Milltek Exhaust whilst not showing any noticable improvement is essential later for effective Stage II, but I'd start with the catback and add the downpipe later when funds allow.

High flow fuel pump, don't mess around with the Autotech retro fit versions like I did as there have been a few horror stories about cam lobe wear so fit the APR one although it is three times the price as you buy the complete fuel pump.

S3 Intercooler, I had the Forge Twintercooler but the S3 OEM version is not only cheaper it's also easier to fit and gives pretty much the same gains.

Only when you've added that little lot would I start to think about Stage II

Once you get to this level of tuning you're ready for the 'garnish', Neuspeed highflow discharge pipes etc. but by then you'll be more of an expert on it than me

HTH"

....... I should point out that the above post related only to performance mods and not handling ones.

If it were my money I think I'd REVO it, add a panel filter and fit Koni FSD's & Eibach Springs

Thanks for the replys guys, I think ive decided to go with Revo and a new DV for now, and maybe a K&N panel filter, Emailed my local revo dealer and also asked him for a price of a "Forge DV"

he replied with "Forge Dump valve would be £131.58 and fitting £59"

Im guessing because of price it would be this one (Click->) Forge Motorsport | Alloy Fabrication

now, without wanting to sound old (im not im 27) but is this thing going to be loud? Also seems a bit pricey

i reckon you would be wasting money getting the DV. id just do it when i brakes, which might not be for a long time yet, especially buying the forge one. As apparently the new OEM D revision is meant to be better than the forge, is only 40ish bucks, and doest require servicing

is there a way of telling when its broke? cars done 35k miles, mostly motorway driving

I just dont want to spend £500 on a remap and be dissapointed because the DV has gone and i dont know about it

you'd know if the DV was gone as you would have a big lack of power. and loads of flat spots in the rev range where it isnt holding boost

How do you service a forge one then? and how often ?

Looked ofr the service kit but couldnt find it

drop a pm to mater, he had the forge DV before reverting back to OEM. he should be able to help you with that

remap + holiday.

Just seen your post.

I had the Forge DV for quite a while (around 15k miles iirc) when it worked it was great. However i wanted to maintain the OEM operability so went with Relocating the DV. This seemed to give better response lower down the Rev Range.

The main reason the Forge one was needed is because on the KO3s Turbo the DV is attached directly to the Turbo. This makes it get very hot and thus in turn the Diaphragm became very hot and was then prone to splitting - even on standard cars.

The Forge DV is very very good however for around the same price you could relocate your DV to the KO4 location as i did. This puts the DV at the front of the Engine so that way it doesn't get hot so is less prone to splitting even with extra boost.

The service kit from Forge isn't a part they sell. If you have the Forge DV you just ring them up and they send you a new piston, spring, grease and all washers/seals. You just remove the DV then unscrew the top of the DV give it a good clean using petrol/methylated spirits. Making sure all that has evaporated then replace all the internal parts making sure they are greased up using the supplied Grease. Then re-fit and your away again.

In my honest opinion the New revision 'D' DV's look like they wont break as i'm pretty sure they have no diaphragm (only seen the pics so maybe someone who has one can confirm) so if i were you i would buy a new DV (circa £30) and keep it as a spare until your Current DV goes. If & when it does go then replace with the New revision. It will save you around £150 + fitting

Forgive my ignorance but I thought aftermarket DVs were fitted only to give that cool Pssss noise when you change gear, not for any performance or drivability improvements. If this is not true then please educate me (then I might be able to justify one to myself)

Does the latest D revision OEM DV give more Pssss noise?

The DV doesn't give any noise whatsoever.

On a Mk2 Octy (can't comment on the Mk1 Aftermarket DV's) you need to fit a spacer like a Forge BOV or adjustable BOV to get the Psssst noise you talk about

HTH

Although located in the same area there are two items which I think you are getting confused over. The first is the atmospheric spacer which Forge manufacture two types, fixed or switchable these both give the phtssssssh' noise that some owners crave.

The DV serves a different function which are known to 'split' so the only option until fairly recently was the Forge aftermarket version but now VAG have produced a much more reliable alternative fitted to current vehicles which is the latest revision D you refer to.

HTH

Thanks chaps, that's clear(er) now.

I always thought DV or Dump Valve was the noisy bit, but it's actually a blow off valve BOV (makes sense).

So what advantage does a FORGE or other aftermarket DV give you (apart from not splitting like the VAG 'C' revision DV has a habit of doing)??

Nothing at all as far as I can make out!

Doesnt it allow for different springs ie stiffer ones when running a map with more than average boost?

hmmmm I'm not so sure about that ................ if I remember rightly, Forge had a few issues with the DV before it was finally launched making sure it operated correctly but I dont think the spring mechanism is any 'stiffer' that the OEM version ..................... although I could be proved wrong

I seem to recall different colour springs - yellow, green and .... hmmmm. Or am I thinking of my old Octy 4x4 turbo BOV.... :confused:
