[felix da cat]

alright here goes. so im picking it up tomorrow and here's the list of mods i've got planned to start with.

double din head unit

CAI - gonna use a carbonio style CAI so i get proper air flow

2.5" turbo back exhaust

new DV - not sure which is best

k04 turbo.

what i'm not sure about is do i have to do any other mods to handle the k04?

your opinions and any other ideas welcome.

thanks guys.

You can get software to run the K04 but you'll miss out on a fair bit of power. To get the best out of it, you need to change to the hardware from an S3. Fuel pump, FPR, injectors, MAF.

thanks for the welcome. any idea where is a good place to research the bits you suggest? new to the world of vw's so not familiar with the places to look.

cheers, scott.

from time to time there is stuff up for sale on vwvortex forums, and also on ozaudi.com for sale pages.

also, if you searched for the stuff on ebay uk, then you're bound to find some juicy deals.

with just the k04 and exhaust, intake and remapping, though, you're probably going to want to invest in at least coilovers, sways, brakes, and also an LSD.

good luck! should be sweet!

cheers,

is there a huge difference from the k03 to the k04? always like the idea of more power and i've already got some mods listed.
easiest k01 to go with would be the k04-001 yeh? (isnt this a hybrid)?

yeah what is the size difference of the k03 and the k04

im assuming the k03 puts out about 8psi? if im wrong tell me!!!!

I'm doing the K04-001 change soon. Going with APR software so you only need the FPR and K04 turbo. If you go with GIAC (I think) they require you to have the larger injectors and the S3 MAF. So it depends how much work you want to do. The K04-001 is the same external size but larger internals than the K03, hence the direct swap. Or you could go with a K04-02x which is larger in size both internal and external, so you then need a new exhaust manifold, downpipe, and I'm not sure who has software here in Aus for them. It's also a good idea to have a FMIC if you going to run a larger turbo.

Like Scotty said, you may want to invest in brakes and suspension.
Thats were I'd be spending my money before going bigger turbo and remap.

Just curious, anyone know somebody thats transplanted a 2.0T from a Mk5 or 6 ?

I think its worth taking a step back and working out what you want and what you have to spend. The K04 is a good upgrade, but its really not going to give you a lot more power over the K03.

K03's run around 8ish PSI stock, with a tune that comes up to about 17psi. The tune alone would bring you up to the vicinity of 120kw ATW.

I'm not sold on the k04, if you want real power, consider a bolt on option like the Garret GT28RS, whilst more expensive it gives the potential for 200kw ATW, substantially more than the K04 (around 150kw ATW?). To do it well with supplementary parts to work well with it, I'd allow $8k.

If you are after a generally fast car, a chip and a good suspension setup will do wonders.

When you start looking at a turbo upgrade, there are lots of options and good accompanying hardwares: exhaust, intake, manifolds, injectors, etc. The best way is to know how much power you want and to work from there...

How many people though have a spare $8k to throw at their car just on engine work? If he is starting with a standard car he can go from 110kw>>180kW and 210nm>>388nm for only $4.5k using the APR kit or under $3k if he sources parts himself and shops around for a tune. For most this is a much more practical exercise and leaves them with money to spend on suspension etc.
