ive only had my b5 a few months has 50,xxx miles. ive replaced all coil packs and plugs and upgraded divertors. i have apr software and straight 3inch exhaust no cats or mufflers. do i need to upgrade my hoses and the n75 valve as well.

 

Just keep an eye on the throttle body boot right in the front, they like to tear. and if the n75 isnt giving you problems dont worry about it.

 

i have a wierd intermittent stutter it seems. kinda whistles up front i think. hard to tell my car is loud. boot looks good

 

www.awe-tuning.com has a pressure testing kit and instructions so you can go to home depot and make your own if you want. You just attach it to the acordian hose before the y-pipe and pressurize your intake tract, that will let you know if you have any boost leaks. Then fix/adjust accordingly.

 

cool thanks

 

is it worth it to buy a new hose kit? are the ebay kits any good their so much cheaper than samcos. thought about front mount or aftermarket side mounts. or just a little 50 shot wet system. how can i increase fuel if i setup a wet n20 kit?

 

Generally the ebay kits are good stuff you just might want to have an exacto knife ready to cut of a little excess silicone. Really what matters is that you clamp everything down good and tight.

new sidemounts are also a good upgrade. AWE makes a great product that fits well and comes with shrouds, ER intercoolers are even larger. Ebay and JHM frontmounts are also good inexpensive intercooler solutions that perform well. JHM even offers black intercoolers so you can keep your grills and the sleeper look. All of these options will also be suitabe for k04 or larger turbos if you upgrade when your k03s give out. Rs4 and Ipp intercoolers are larger than stock and will work well with k03 turbos, but you might want someting larger for K04's leading to my reccomendation of AWE/ER/FMIC

Maybe make an account on audizine (im sourdiesels4) and send the OP of that thread an email. He seems like he knows what hes doing. Or you might get an answer here from someone else
