I've just got a audi a4 b8 2009 stock and I want to put hat car to 350hp .I want to know how can I able to do this. I have a setup in my mind (short ram air k/n, catback borla 2.5",chip unitronic stg2, bov adaptor,and bigger injector) if everyone else have an idea to help me to upgrade my b8 I'm open at all thanks Dave

 

You won't need bigger injectors, it's direct injection. Using a blow of valve will cause check engine lights and rough running. You also do not need a full exhaust, B8 exhaust is very large and free flowing. For the CAEB 2.0t, check out RAI motorsport. They have some options available.

 

If u can get this car to 350 with the stock turbo please share how. I've heard id be lucky to get it to 275hp.

The stasis turbo back exhaust has the best dyno numbers I've seen, +15hp with engine software. Also consider upgraded fmic. Eurocode seemed to be the favorite when I was looking last year. There weren't any good CAI last time I did research (e.g, k/n typhoon and Apr carbonio both had issues).

 

There is no way to reach overt 300 HP with the stock turbo. It simply wont put out enough PSI or flow enough. RAI offers larger turbo upgrades. The Stasis tune is very conservative, and I know there is some rumoured headbutting going on between Audi and Stasis for warranty claims. Other companies have yet to gain much more over factory power levels because of the same issue Stasis runs into: leaning out. The CAEB and CPMA run very lean and upsetting that balance by running high boost can run into leaner mixes and higher temps. High temps with the new TFSI can cause fuel vapor lock in the rail, stalling, and bucking, and ultimately boom.

 

PS: skip the CAI... the stock airbox will outflow almost anything aftermarket. The TFSI is extremely sensitive to intake modifications (in a bad way), so don't bother unless you are going with some huge turbo. Its nearly identical to previous 2.0T/1.8T airboxes, which have been known to flow over 400hp without restriction and run far better than any "CAI."

 

yeah i knew the turbo wasn't capable of those figures.

giac stasis and apr #'s look similar to me. hard to compare apples to apples. APR uses 93oct and GIAC just reports a range, not actual max. but maybe stasis tune is conservative compared to other brands.

anyways i was referring to Stasis Exhaust. I never recommend Stasis ECU tune to anyone unless they want to hold the warranty. which ended up being the reason i went with it. i'm still trying to get my oil consumption issues fixed under warranty.

 

Sorry to thread jack, I come from the rotary world this is my first post.

I have no issues putting a larger turbo on, turning up the boost and praying to the rotary gods. However I have no clue how to rebuild a piston engine, nor would I even attempt the feat. I am looking at a 2012 a4 2.0 6 speed quattro with 10,000 miles....

I want at least 300awhp, it appears that the 2.0 is lasting to 50k(ish) unmolested. So could I assume that getting it up to 300 would reduce engine life to about 30k? Or am I wrong in those assumptions?

Again sorry for the threadjack, I hate clogging sites up with new threads.

 

Where are you getting these numbers? I regularly service 2.0t chain engines with well over 100k miles and no major issues. Oil consumption issues were fixed with the 2011 model year. The engines are just as capable fire 200+k miles as any well maintained 1.8t or 2.0t belt motors.
