whats require to get audi s4 b5 to 400+ bhp?

Bigger turbos - K04's if you can find cheap, or Tial 605's are both a very nice choice.
Any kind of injectors that flow 450cc or more at 3 bar.

Exhaust and downpipes.

Meth injection or thicker head gasket recommended as well, so it doesn't overheat so quick.

Change element inside the MAF for RS4 one (no need to change housing for 400+, only for 500+).

Clutch - SRE pressure plate, and stock disc work fine.

Remap.

Thanks for the replies

Buy one that has already been k04'd, there are a few appearing for sale lately and it will save you a fortune

and how´s the feeling with a S4 saloon with 500hp?

would be better than the same power riding a 80 RS2 saloon?

different chassis,different engines and the same transmission


you have to spend a small fortune in both i see..

I've also got an S4 saloon with K04 RS6 hybrids running 515hp and +711Nm. Trackdayproject with a 2 friends, and with a fully stripped interior and adjustable suspension it really is FAST. The rush in 2nd for example is addictive
Also very agressive turbo's at low revs, with quick spool.

My mate stuck rs4 mani's turbo's downpipe's and system onto his s4 powered passat. We ported the intake mani and fitted a fmic made 480 with feel sick in the stomach torque.

Well I'm on a stage 3 spree and it is as follows:

Wagner Exhaust manifolds
Wagner Intercoolers
Wagner 3" downpipes
Jetex 2.5"" cat back exhaust system
K04's turbos
034MS 89mm MAF housing with adaptor and OEM RS4 hose -
DW300 fuel pump -
Bosch EV 550cc injectors for the electrical adaptors.
Forge Motorsport silicone hose
034MS throttle body hose - The forge wont fit under the stock cover.
RS4 intakes pipes
RS4 Clutch

I can dig out what I have paid so far for the parts, but a ball park figure is close to 6.000 euro.

But ok I may have gone overboard with all the wagner parts

What a dream list !

Do you know what the engine bhp is and also the torque ?

Enjoy.
