Hi,
I have an Audi A4 1.8T rated at 163 horses, and would like to know if there is any easy and (fairly) cheap way I can increase its power? I would like to increase power by about 100 more horses, if this is possible.
I did look into remapping, and quite a few places said that it was not worth it.
Any advice or ideas would be great thanks.
Cheers!!

STBDriver.

Not sure whether that's a different engine to it's big brother the 190hp engine which can be mapped for an extra 30+ horses ,however some guys in the know should be along to put it right.
Check Google.

You don't say the year of manufacture but I once had a 2002 A4 1.8T Sport with 163hp as standard and that was mapped to a claimed 195. There was certainly a very noticeable performance gain, particularly in the mid-range. Unfortunately I can't remember the name of the tuning company!

You won't achieve another 100hp just by mapping and I suspect a such a power gain would by very expensive.

A 100hp boost would require something like a larger drop-in K04 turbo conversion kit. Something like this:

Sell it, buy a more powerful version.

Hi...sorry...2003 A4...I realise that mapping alone wont do it, but would like to top 200 horses...

And you think upgrading what you have will be hard ? 1.8T engine can make 400hp without too much bother, its all been done.

The way this will go is you'll spend a couple of grand on a 10 year old car, you'll probably experience some premature wear due to the upgrade and then want some more performance from it. You then either throw a boatload of money at it to put the car in a decent state and get the power you want or get rid of the car for next to nothing and get something else.

Here you go, this will get you your 100hp http://www.goapr.co.uk/products/turbo_b6a4_k04.htm...

Too simple an answer to what was quite a simple and straight forward question....and a whole load of assumptions too. Oh well....thanks for the link...

Assumptions get made when you don't provide enough information. Saying something is "too simple" doesn't help. What do you think is wrong with 'simple' anyway?

163 will be a K03 engine and map to about 200 ponies.

They go fairly well in this state of tune and have a pleasingly beefy torque delivery. You may well find this is all you want.

Seriously, how much more information is needed?....., or how much simpler could I make my original question.....????

Thanks very much for the info Dr G. Sounds about what I am after.
I will look into mapping some more. Cheers!

Well, you flamed someone for "making assumptions" which means they had to make a (hopefully intelligent) guess about something, which you consider wrong. Maybe they incorrectly assumed your budget could stretch to a new turbo? I don't know, because you haven't said what incorrect assumption was. So now I'm making assumptions about their assumptions frown

Anyhow. There are a few constraints that most people have : desired reliability, cost, ease of installation, ongoing maintenance.

So, how much money are you hoping to spend (varying from 'none' to 'whatever it takes', but preferably expressed approximately in British pounds)
.. And, what do you want to use the car for (and thus, how reliable does it need to be?) Drag racing with rebuild between each event? Race/Rally with maybe an annual rebuild/refresh? Weekend track day toy? Daily driver on school run/commute?

I have had a couple of these maps, and they are very good. Some say a little harsh, but that was to my liking.

Remap with the standard K03 will give good results (main difference is torque rather than out and out BHP).

If you are serious about nearing 300BHP then it's an expensive business, I ran a GT28RS turbo on a 1.8T quattro sport (180BHP standard), that got me 250-280BHP but included an intercooler, bigger brakes an a lot of build time (read money), I ended up going further but that was silly money - the main thing the experience taught me was to set the ultimate goal and ensure you grow towards that, doing things ad hoc is a very expensive way (even the K03 map will be a few hundred and that's throw away money when you do further upgrades.

If you do decide to invest I'd avoid the K04 upgrade - I did that and immediately wanted more! The GT28RS was probably the best compromise between drivability (fast spool at low rpm) and top end increase.

Hope that helps.

cost me a serious about of money to get my Mk4 Golf turbo 150 just to 237bhp (dyno proved)

Remaps are usually good for a reliable and realistic 20-40bhp on turbo'd petrol cars and as soon as you go away from remaps your cash quickly vanishes.

Bigger turbo or a rebuild/hybrid version of your own along with better fuelling, exhaust, air filter and the thing that seems to hold all earlier VAG engines back, better cooling.

£1500 hybrid turbo
£800 exhaust with decent sports cat (do it properly!)
£100 air filter
£100 uprated fuel pump
£500 FMIC
£300 custom remap to make use of the mods

3 options

1) get it serviced and mapped - enjoy the extra grunt. save your money.
2) do all of the above but do not expect to see a penny of it back and also allow for everything else breaking around it as its all being pushed beyond its design.
3) sell up and buy a large engined car instead (plenty of bargains to be had) - expect to use every penny you've saved on fuel, road tax, tyres and servicing smile

i think i would go for number 1 smile
