im buying one today and have never before dealt with audi's. can someone post a link to a website with some turbo's / turbo kit's for my car. also if someone could give me a little advice as to what kind of power i can throw into the stock block, stock tranny, stock difs, etc. re-worded: where are the weaknesses in the audi a4 1.8T? any and all info would be great thanks guys!

this basic info is all over the forums. Read the A4 newbie guide, it has all the info.

But to give youa head start. The block will do just over 300ftlbs before the rods need changed. After that, the engine is strong as can be. The clutch will need to be changed to hold the power.

you can look for upgrades at, aptturbo.com and goapr.com

thanks man how about at 400ft lbs? will everything besides the rods hold up? (tranny difs etc.) sorry to ask such basic questions i figured id get answers with more detail than the newb section could offer.

All you will need for above 300ftlbs is rods and a clutch to hold the power. 400tq is a lot and would be matched wil over 500whp.
