They were tight a 1k miles ago when installed.

here is my car - b6 s4 avant 2.7 heads with 2.8 intake cams (slower boost) vs buddys b5 s4 with 2.8 heads and cams with a port and polish ( he runs a boost controller innovate scg-1)

ive noticed when i start the pull at 2k rpm i build boost faster then when i start the pull at 3k

Hey, I don't mean to clutter your thread, but I seen in a previous post you mentioned grabbing some stuff from a wrecking yard for your build. Where are all the audis in wrecking yards in Arizona? The only junk yards I've been to have nothing but old American cars, and some Japanese imports. In over 10 visits to various yards around Phoenix I've seen a grand total of 3 a4s, and 4 a6s.

there aren't many . i just search u pull it lots and when they get one i grab what i need.

got a euro trunk lid for y b5 s4 today , 2 hitachi mafs and a return fuel line. tired of messing with the 2.7 ecu and making it returnless . maxed out injectors so going to return fuel system. thought about going 6bar regulator but return is so much easier to tune and i can use my scg-1 boost controller and switch boost on the fly . hopefully i can install the line next week and get back to tuning . also see what a difference the boost controler makes on spool up time

well haven't done much to this for a bit due to the fact its crazy hot here and i had a girl . Still havent installed a return line but maybe here in a few weeks . i did buy some wheels to refinish though

Bought a set of hre 540r's , going to powdercoat the centers the same as my valve covers bubba blue from prismatic powders and polish the lips . they are painted silver with flake so it will take some time but ill show the progress

Ok so looks like photobucket has become huge dbags and don't allow 3rd party hosting unless you pay 39.99 a month or $399 a year wrf. so what are you guys using that's easy and fast.

wheels are done , assemble them this week and order up some tires and then see about lowering this thing.

Intense colour combo.

Interested to see how they look on the car.

PS: what happened to the stk build? scrapped?

12-13-2017, 07:35 PM
Oh no I have another built bottom end that needs rings. I'll get it put back together sooner or later and get a stk going again. I also pick up a project B5 stk because it was stupid cheap for a later project. I just had to do this to get it going ( needed to get the car out of my work ) I still want a single in this car at some point.

Also getting a Jeep Cherokee from my buddy that has some front end damage to build into a crawler so I built this rogue fab bender . To many projects and not enough time

been here just no time , my kid is 18 months now and im slowly getting some time back lol. No more pics of the avant . she is running good . ive spent some time on a silver sedan i have that i threw k24's on . just getting it wrapped up to let brad have is for a week and get her tuned up . here a pic of the sedan im finishing up . then ill be taking a wack at wrapping the nogaro car . Still no singe but it will happen . i still have a built bottom end for one . i need to make a junk yard run and grab some 2.8 heads for it but hoping ill have one this year . once this silver car is done it will be up for sale then hopefully get the noggy a little more sorted out . needs new front seats and figure out why it wont make more then 20psi on k04's Then a retune from brad and see if i can get her into the 11's
