Engine wise it's staying "as is" now. It is the 2nd car so don't feel a need to make it better than the Ed! Can't have the GF beating me! So no FMIC. Just need to get my calipers painted and get some new alloys to complete the asthetics now [:)]

Don't be scared! In hindsight the job is quite easy, just a little daunting. There is just alot to do. The worst bit is refitting the exhaust after finishing the turbo as you just want to start her up!

I'm pretty sure you can get away with not removing the exhaust manifold and maybe missing out some other small details in the guide but I got to the point where I wanted "everything out". I hope people try and follow the guide and comment as it would be nice to know where time can be saved without suffering the "I can't fit this bl***y bolt it's too tricky" situation.

Ha, fair enough ! Its only pipe dreams at the moment, but seeing stuff like this makes me wonder. If my turbo ever needs replacing, I'll give it a go. I don't want the fmic and too old for a noisy exhaust (been there though!) and wondered what gains would be with maybe just another map + K03s. Mine should be around 190 at the moment with the K03 (though I'm sure its not as quick as it felt when I had it done!).

So how different does the K03s feel?

The k03s is another leap like the original stage 1 generic map.

I had been running the "stage 2" bits on the k03 with a stage 1 map so I would have been wringing every ounce of power out of the k03. So I expect I was running close to 200bhp.

So "all" I am feeling is the k03s and stage 2 remap effects... a very worthwhile upgrade!

Very good write up mate. Very impressed with the attention to detail.

What sort of price did it cost for all of the gaskets etc roughly.
One thought though nothing to do with this excellent guide, I can't see why the car would need to be mapped again, other than to get a bit more power out and use the turbo more efficiently. The N75 valve controls the requested and actual boost figures, so effectivley the turbo will only produce as much boost as the standard K03. Obviously it spools up quicker so fueling could need to be adjusted to suit, but I'm pretty sure that if the car has been mapped over standard then the car should run with the original tune and the new turbo.
This is more to do with people worrying about running the car on a map with the turbo changed. Obviously to get the full benefit the car needs mapping properly.

Just my thoughts (not looking for a flaming) What do others think?

Another quick thing, What other bits can be added to get more power - Injectors, MAF housing, 4bar FPR?? How much power will this give?

Hi BadPuppet [Y]

I will update the guide with prices for the parts early next week.

The k03s is slightly larger / more efficient than the k03 at producing boost, so for a given wastegate position (under n75 control) you will get more psi (I am pretty sure that statement is right). The k03s has to be better at producing boost as it maintains psi right up to the redline... whereas the k03 runs "out of puff". So for every turn of the rotar more air is moved.

Remember on an AGU there is no MAP sensor to feedback actual boost so it runs "open loop" to some degree. The ECU modulates the N75 expecting to get 15psi (for a stage 1 car) and gets 20psi! Then how should it fuel? It needs to know what duty cycle to run on the injectors for the additional air being blown into the engine. So although you can run a k03s on a map not designed for it you are ultimately best to get it remapped to fuel it right etc...

As for injectors, MAF, and 4 bar FPR you will probably need a custom remap. Some may have these maps "off the shelf" but remember they have not been tested anything like the generic code that "most" people have. Generic maps have 1000s of hours of testing. There is something to be said for staying with standard "stage 2" parts. If you go with a custom map for your car there is no way of relating issues to other cars as it is totally bespoke. I'm sure you would get more performance but with many dyno runs and niggles.

These are just my thoughts [:)]

Hope this helps [Y]

Blimey some action on my "how to" [:D]

Hi Patch,

The banjo bolts aren't on the list. I think it would be a waste of money really. There are already quite a few items on the list you won't use if all goes well, I just can't think of a reason to replace them.

If anything I would buy an additional 4 oil seal washers. It all depends whether the turbo is bare of feed and return lines... as that dictates how many washers are required! I re-used the water feed washers as they were stuck firmly on the banjo bolt (see my "wotnots" picture, you can see the banjo bolt still on the coolant feed).

Are you doing this yourself?

[:)]
 
I think an extra ÂŁ50 quid with me would of been money well spent lad lol
Maybe,but think of the fun i've had[:DD]

I've learnt a lot along the way and would help any of the Pit Crew fit one if and when needed,it's another thing that we can all add to things we can diy list.

Glad you got sorted Patch.

If anyone is local to Leicester considering this, I'm up for another fitting battle [Y]

Once you've done one they're easy [:#]

Mega write up NooNoo. I will be using ths over the corse of December when my K03s terns up :D
Have you got yourself a decent k03s Lee?

[:)]
 
im bringing this back .. lol

question, this Elbow Hose in this pic. The forge replacement for a k03s is a 225 k04 hose (for audi) would be the one that fits? As the k03 one for the agu setup doesnt fit my k03s hybrid?

Any help appreciated!

Thanks
