TBH, the only thing that would tempt me away from going K04 on my TSI VRS, is that its not 4wd, I would be tempted to change to maybe a scooby or Evo, and then you can deploy the power a little better when the notion takes!

I wrote a bunch of stuff on my blog when I had both the TSI Vrs and WRX STI on my drive..

Yes, the subaru is very, very fast and put its power down fantastically well, BUT:

- build quality is better in the skoda

- ride quality is better in the skoda (yes, even mine on coilovers!)

- fuel economy is massivly better in the skoda (21mpg only for the STI- ouch!)

- practicality much better in the skoda (rear leg room and much bigger boot)

- depreciation on the STI was eye watering

Maybe the ideal would be TSI + K04 + diff?

Trust me a diff on a FWD car makes a huge difference. You have less weight without 4WD too.

KO4 would be my thinking when everything is taken in to account. And i'm with you and putting it back to standard. Even though you lose a lot more money I just cant be bothered with all the hassle. Been there done that

Im still on standard OEM clutch ATM and seem to be coping.

I'm in the same boat and have briefly looked around at a KO4 conversion.

I think Harrys method is the most cost effective (especially the price he paid ). Buy a ED30 engine and KO4 turbo and do a straight swap for the vrs lump. I suppose if you arent in a rush you can hold out for an engine and turbo at the right price to make it all worth while.

I would have thought a tsi and KO4 would put you in the 15k price bracket???????

Harry if your going to the Shark RR Day i'd love to see the difference the LSD makes

I am going Mark, see you there mate.

The K04 upgrade for the TSi would be circa £3-5k depending on what mods you already have. The turbo is not a straight bolt on as it was on the TFSi. You either need to buy APR's ready made kit which is £1600 is with conversion rate plus tax if it gets caught by customs. Or you could buy the turbo yourself and get it machined. However a new turbo is about £1300 from VAG & your looking at about £500's worth of machining to be done. So that really wouldn't be an option unless you can get hold of the turbo cheaper say off eGay etc.

The only things you need then are DP and Intake/pipework. No need for injectors this time as the one's on the TSi are easily able to cope as is the fuel pump.

I guess deep down I do want k04 so I'll continue to look but I aren't going to pay the earth for a conversion, I just don't think it would be right to spend huge amounts of money on a car worth about £6k.

I've been a bad lad and have been looking at the BMW 335i on you tube, they are damn quick when mapped

Yes buy a KO4 and remap it again. Youd only be 20 horses down on a remaped 335i (340bhp remapped KO4 against 306bhp standard 335i + 54bhp mapped) and would have saved a great load of cash and messing around in the process.

Sensible thinking Rich, I'll have to see what turns up

I would imagine mpg would be a bit higher on the vRS and, lets face it, it's an all round better car!

So if your at stage 2+/3 what are the costs if you went for a ko4?

Injectors

KO4 turbo

Remap

What else do you need? Manifold or DP modification?

So budget for 2k + the car. Got to be around 12-15k for the right package?

... APR's ready made kit which is £1600 is with conversion rate plus tax if it gets caught by customs.

Do APR have any UK distributors? £1,600 for a bolt on kit seems like good value to me.

Not that i'm aware of. It used to be Awesome GTi but not anymore. I think JKM can get them in but you would have to speak to them. Remember you will need to factor in customs charges and labour on top. Plus the other bits below if you haven't got them already.

Main things you will need are

Turbo Kit

Intercooler (S3 Intercooler is fine and fits straight on)

Downpipe (Miltek etc) No need for cat back unless you want a res one to make louder

K04 Intake

Piping for intake take off from turbo and intercooler

Wiring for the DV

Associated seals etc

Can't think of anything else off the top of my head

Ahh sorry i was taking into account that whoever wanted the kit already owned the car so wasn't factoring that in.

Im pretty sure he has the 2.0 tfsi ATM and he would need to sell as is or return to standard to buy a tsi.

ut still its an important factor as it looks like its much more cost effective to ko4 a tsi than a tfsi

Tsi and k04 is well out of the question for me, it would be too expensive. I have a lot of the mods needed for k04 conversion already, I would only need:

Turbo

Injectors

Turbo outlet pipe

Dv relocation

An S3 air pipe for the Dv relocation kit to join to.

K04 remap

and a few washers and seals.

You'd be looking at £3000 fitted then Martin.

Well I have just got back from picking up the following:

Turbo

Injectors

Turbo inlet pipe

Turbo outlet pipe

Dv relocation

Just need the following parts and I'm sorted .

Dv wiring extension

K04 remap

Good man, knew you would. What did that little lot set you back?

It was very reasonable

You're finally doing it then Mart - well done mate

Looking forward to seeing the results
