If you had $2000 to spend and a Silver 2001 Audi S4 which mods would you perform? Labor is free Parts only......

 

Well done mate
Before u mod make sure the car is right, eg TBB and the belts have been done depending on miles obviously
Then chip and maybe squeez an exhaust in the 2K

 

He's got it right, the TBB (throttle body boot) and the F-hose are major problems after longterm use with your car. (because they are made of thin-wall rubber) They can lead to turbo failure, but mostly just a loss in boost. The first thing I would go for is either beef up those parts, and maybe go for a SAMCO hose kit. Its runs about 300-400 bucks (US). Then look into GIAC chip upgrade and boost controller/ turbo timer to untap your engines potential. Then get into exhaust and some of your fuel system, all that plus tuning should run you near 2K. Then you are looking at a turbo upgrade! Happy tuning! For some good info, go to www.s4biturbo.com, its all there in black and white.

After maintaince, get a chip, & exhaust.

Watch out, I have spent over $6k on my S4 since I got it 2 months ago.

 

Chip, Exhaust, Diverter Valves

 

I agree w/ everyone - upgrade all the regular stuff ie: DV's (710ns are fine...)
f-hose, TBB, etc... + timing belt water pump etc... depending on mileage...

I cant wait to get chipped -

but first Im getting suspension... Coilovers...

 

Yeah it can be a bit of a rude shock when u buy a B5 S4 and all u wont is more go - but u got do the maintaince 1st and get it sorted
Ive spent over $1,700 just on repairs + maintainece
Over $ 1,300 on tyres
This is all on a very low mileage car 2 and am now ready to chip + exhuast
Cheers

 

2nd waht every1 else said, TBB, DV's, chip and exhaust. You can get a catback from a dedicated company for that price range, or if you go custom you can get a full turboback.

 

Im in the same boat, looking to squeeze a little more power. Any suggestions on manufacturers for the TBB, DV, and chip; APR?? Eventually would like to wrk it up to stage 2.

 

710N DV's = Vast Performance
TBB = Samco
Chip = Do a search, extreme amount of info in archives
