I got a 2002 B5 S4, with 96,000 miles.

-APR93 chip
-K&N intake with heat sheld
-turbo back ssautochrome exhaust
-Boot gauge (18lbs avg.)
-Red DV's ( i dont know what they are, they came with the car)
-Original Ko3's

This car is damnfast, what can i do to make is faster.I don't have lots money but i could drop $1,000 for some more HP. I know the APR chip is encrypted and cant make changes to it. I think getting it more fuel might help.
Do Innercoolers make HP?
Bigger Lines somewhere?
Fuel Pump?
BiPpes?
What should my next upgrade be?

More power- GIAC XR Chip- run 100+ octane all the time
Faster- weight reduction. CF hood/ trunk- lighter wheels- Jenny Craig -
Not much you can do morewith the k03's. [:@]
IC's could help.

 

Save your $1000 and be patient to save another $1000. Then go pick up a set of K04s (it might cost you a little over $2k depending on where you look) and install them yourself. Unfortunately, you're going to hit a plateau (which it sounds like you are at that point) with the K03s where there isn't much more you can do to get more HP. The GIAC XR and 100 octane will give you a nice boost, but with gas prices rising, paying for 100 octane at every fill up will get expensive.

 

Thanks for the info.. I could pay the 2,000 for ko4 if im interested in more power in know. What about the fuel system and other stuff to go with the new ko4's.Basicly, what is absolutly NEEDED with the KO4 to get them running.

 

K04's $2000+ (price is going up)
Inlets $500
Hardware < $100

when you run k04's without fueling its called stage 3- , you will get more power but your right your stock fueling wont show the full potential. I would reccomend a stage 3- chip: you can find them cheapest for sale in classifieds here, audizine, or audiworld.

Later on if you want to go full stage 3, get a fueling kit and some intercoolers and your set

 

K04s are drop in replacements, get the plumbing kit that goes along with the turbos and that's it.

Now, if you want to go stage 3, you need the fueling kit as well, but it's another couple grand, so you might want to budget for the K04s now and plan on doing the fueling down the road when you can save up enough $$. Once you have the turbos and fueling, you just need chip/ecu prog to go along with the new hardware and you're set.

But in answer to your question, you shouldn't need anything extra to get the K04s RUNNING. You just need the additional fueling/tune to get the real potential (increase in HP) from the K04.

 

Looks at the kits on AWE, VAST, ASP, depending on where you are EPL and JHM are great custom tuners. turbos are going up in prices very soon. The fueling/tune for stage 3 can be anywhere from $1500 to 2300 depending on where (or who ) you get it from. some peopleare selling their stage 3 fueling setups for well under 2000 because of going rs6 or gt setups.
stage 3- tunes are fine if the $$ isn't there yet. APR's stage 3 fueling is rediculously expensive.
Also, you will need a new clutch/FW to go with the stage 3 goodies. along with all the other 'little' things that add up very fast like seals/ gaskets and mounts etc.
Ya it's not the cheapest, but it certainly is very worth it

 

get aWater/Meth Kit, then spend the grand to rebuild the internalsof your motor...

haha

 

I'd do ic's and piggie pipes right now,and thensave up for K04's.

 

Haha about the equivalent of stage 3-

Water/Meth on K04's wll give you some power... Internals are nice if you have turbos that will support 500+ wheel hp, and a valvetrain that will support an 8500 rpm redline. Otherwise i cant justify thousands on rods, pistons, springs, valves, heads, cams, etc and still be using k03's that no matter will hit a wall at some point (its closer than youd like to think)
