How much extra would it cost you to convert the GTI to a K04?

How much would extra would it cost you to trade in for an ED30?

Which would you rather have..?

i think about 2k to convert, i already have the parts but will it be safe to do on a 89k milage car? for around 9.5k i can get an Ed30 with less mileage, im just worried about the mileage

Unless you're going stage 3.. Is there any need for a K04?

Please correct me if I'm missing your point..?

iirc martziniuk did the k04 upgrade on his car that had more mileage on it than yours.

Why would you want anymore than stage 2+ in a FWD car though?


A stage 2+ K04 is more powerful than a stage 2+ K03, so stage 3 has nothing to do with it

Stage 3 on a Golf GTI needs a K04

Stage 3 on and Edition 30 needs bigger than K04

What im trying to ask him is,

Why does he want a bigger, K04 turbo?
Is he thinking of going stage 3?

stop making arguements. ta  :happy2:

wasn't telling him to do anything... I was asking him why, out of curiosity.......

I'm in exactly the same boat here.... I want to change my gti for a Ed30 but the prices are silly high at the minute and i could never find the same really high specked one like my gti is.. I'm wondering just to ko4 it and keep it.... I'm already around 280bhp and 335 lbft ft. A k03 is almost maxed out now where as with a k04 it will obviously do more.... But then you have to equate the cost of a clutch as it will not take the extra power very well at all.

i already have the parts but thinking about weather to sell them and get a ED30, which would be a better choice in the long run as i love the MK5

i might sell my K04 if ur interested mate

depends on what you want to spend? you wont get a lower mileage ed30 for the same price as what it would cost to k04 yours.. but if your willing to spend that bit more and get lower miles and stronger engine then i would say that would be the way to go

Stage 3 GTI will make the same power as a 2+ Ed30, but will hold the power longer at the top end due to the compression ratio  :happy2:

KO4 Turbo upgrade on the the standard GTI is a stage 3 set up and is equal to stage2+ ED30 mapping.

I kinda know what it means, what I don't understand is how it'll be better on the stage 3 gti?


Theyre both 2.0, both K04, I know there will be one or two slight differences, but don't get how the stage 3 GTI will be better than the stage 2+ ED30?
Title: Re: Golf gti K04 upgrade or ED30?
Post by: GrayMK5GTI on April 02, 2014, 07:29:24 pm
Because the BWA/AXX engines have higher compression ratio it allows them to hold onto the power longer in the rev range. Niki from R-Tech posted summit about it on the forum once. It's clear from Dyno graphs too  :happy2:

In reply to the OP, you'll be fine with that mileage on a K04. I'm currently at 127k with a potent map and no issues but you'll need a clutch.

Sell the GTI and get yourself an Edition 30.

- 230bhp Engine which is more like a detuned S3 engine with the K04 turbocharger and other bits
- 18" BBS Pescara Alloys as standard (GTi has 17" Monzas as standard)
- Half Leather seats which are heated and have electric lumbar support
- All the lower skirts & bumpers around the Edition 30 are colour coded (looks better in my IMHO)
- Smoked Rear Light Lens (same as the R32)
- Red stitching on the seats, mats, steering wheel & gear knob plus Edition 30 badges

280-300bhp easily obtainable with the right mapping (Revo, R-Tech or APR) :happy2:

Depends on the OPs situation tho, does he owe money on his car on finance? What else has he done to the car?

Pointless changing if he's already done quite a few mods for it and will ate a hit on trading the car in.


Although I do agree in principle mate

I think im going to K04 mine in the next couple of months, there's no point getting an Ed30 for me as mine has been modified so much.

Plus I can't stand the tartan  :P

Ye obviously it depends on peoples circumtances but if you can afford to, then Edition 30 all the way as its built stronger.

- Larger Turbo from S3 (K04) rather then the K03 on the GTI
- 87°C thermostat instead of 80°C
- Larger capacity fuel injectors (13% higher flow)
- Larger intercooler (smaller then the S3)             (* danishmkvgti - states that std GTI and ED30 IC are the same size)
- Engine block main bearing caps, pedestals are reinforced
- Conrods have larger rod bolts and new bearings
- Pistons have 21mm gudgeon pins instead of 19mm
- Piston top ring is improved
- Recirculation Valve (blow off valve) not located on turbo
 :happy2:

I swapped my gti for an edition 30, mainly because the edition is exactly the car I wanted when I was buying the gti. The tuning potential (the simplicity, especially stage 1 maps giving such good gains) and I got a decent deal in p/x on the old gti.

It looks better in my eyes and I much prefer the half leather tartan rather than the cloth & tartan.

Both however are dsg, I'd never go back. :)

Sell the GTi, get the Edition 30.

I personally wouldn't want to take the risk of putting a larger turbo, on a car that's got weaker internals like Rods.Very expensive if it goes wrong, and also factor maybe harder to sell the car if you decide you want rid without major engine reconstruction.
At least the ED30 has an engine that will run safety at stage 2+ and can be put back to standard far easier if you choose to resell.
The ED30 looks better aswell. IMO.

Post by: GrayMK5GTI on April 03, 2014, 07:14:42 pm
The Ed30 engine sounds better than the K03 engine too!

The GTI's internals can handle 350bhp all day long so don't worry about running a K04, unless you go for WMI or even bigger turbo!

Ed30 does look better and has a few nice touches (part leathers etc) and feels more "exclusive"

Plenty of arguments for and against here. . .  :innocent:

I K04'd my GTI, I had already spent a small fortune on brakes, suspension.....etc......

I know all the work that has been done on my car so on a way it gives me confidence in it, i, planning on keeping the car and have sold all the standard parts I upgraded/changed. If it does go bang I will get it rebuilt stronger  :evilgrin:

The K04 is how it should of come out of the factory  :happy2:

If you have a standard K03 and want to upgrade it sell it and get an ED30, if you have a highly modified K03 and want more then get it converted to K04  :happy2:

Just my 2pence worth  :drinking:
