Just toying with the idea of making my 2002 s3 bam engine abit more enjoyable right now its 265 bhp supposedly was remapped by revo 6 years ago feels slightly slower think the maps worn out lol just wondering what is needed to take it over the 300bhp mark without having to forge it i understand turbo inter cooler exhaust and maybe injectors but just not very clued up on the petrol side of things like what turbo and inter cooler would be best if any one could enlighten me on what i need id be much appreciative
Whats needed for over the 300bhp mark

You're pushing the limit of the stock rods at 300bhp (well, around 300lb/ft).
If you're going to go for it anyways then a very healthy stock turbo/engine with a decent front mounted intercooler, decat/exhaust + mani, b5 intake + filter, WMI. basically every bolt on mod you can get. Not clued up on injectors, im sure someone can help on that front
Most likely you'll want a hybrid k04 with most of the bits mentioned above.

there are a million threads asking the exact same question. some have very detailed answers, search and you'll find all the information you need.
also, imo don't skip on the rods, you'll regret it when one shoots out the side of your engine block

I've just managed to break the 300bhp boundary at Badger5 last weekend.
All stage 2 mods including injectors but without WMI. And running standard K04
Bill and Paul reckon it's down to the healthy engine which currently has just over 150k.
Basically said it's rare to see one hit over 300bhp with the mods I've got.
You can bolt on mods but evenly it's whether you have a healthy engine that will respond well to them.
Only limiting factor for me was WMI and Standard Rods. Bill has eased down the torque due to standard Rods. Yeah i know it needs them and with my plans will be fitted towards end of year.

usual supporting mods..
80mm intake, decent fmic (AH v2, welly cooler, etc), 3" downpipe, decent flowing exhaust, high flow exhaust manifold, possibly a stiffer 10psi actuator if yours is in anyway tired, 550cc bosch injectors and a decent map to bring it all together (IF) your engine is healthy base.
and dont forget Rod Lottery applies when pushing on....

I`m after 320-330hp as well;here are my mods:turbo td04 16t Volvo,550cc bosch injectors,custom exhaust monifold and custom DP,FMIC,inline fuel pump,4bar fpr,200cel cats,custom exhaust powerflow,IE rifle drilled rods,calico bearings,custom clutch
I have spend crazy money,the car is not ready,i`m in the middle of process to rebuild the engine.

td04
hmm
interesting choice
this fits the same as td05 etc?
ive jo idea why people choose 300 as some bench mark
its not a guaranteed on stage 2
id go hybrid if you are changing mani dp injectors etc

I agree with you there Daz...
I was expecting in the region of 280bhp for my stage 2 set up, which is a average figure.
Then on pre run at B5, on my stage 1 Superchip Remap it made 285bhp.... After Bill did some tweaking it managed to produce 302.7bhp without WMI and on standard K04. It whether you have a healthy enough engine that will respond well with your mods....
I just can't understand why 300 is the magic figure. With transmission loss and the added weight of haldex, 300 isn't great. 400-500 is something to aim for. Especially if you're already going to the hassle of building an engine with rods, pistons, Bearings, the only real difference between 300 and 350/400+ is the turbo and a few other small bits such as intake manifold, exhaust manifold.
its more about budget
either go stage 2 and accept what you get
or go hybrid/big turbo.
300 is a great figure from a k04 car
but how much will it differ from a 295bhp or 305 bhp car lol
also worth noting that 300 on a k04 compared to 300 on a better turbo can be very different to drive
maybe try to blag a go in a few? see what you like

Hybrid and Rods are on the cards towards end of year for me.
Not fussed about numbers... More of the way it delivers power and drivability. Like you said it's about your budget...
At the moment I'm going to add WMI and concentrate on better flow and cooling.
Having a break from spending on mods... Lol... Got some stuff to do and spend around house...
Most likely have a WMI kit in June... Cars parked up all week so limited mileage.
And yes... Was shocked and happy... Wasn't expected at all. Hard work paid off
I agree mate,but in my case,it`s a daily car and i want low-middle torque,not high end which it`s happening with big turbos;anyway,if i become bored ,i can swap the turbo with something bigger,i have the supporting mods.
