    If they are a 320 and a 328 would be keen to see a piston comparison. Also amount of carbon build up on valves intake side. Thanks.

    If these things can reliably hit 400+rwhp without opening the engine I will jump to a 320/328 real quick.

    400 might be pushing it. But I'm with you. A 128i has a fairly low initial investment.

    Great to read you've got not one, but two N20s available for a break-down! No specific requests here, just hoping that we can get the standard bolt-on tuner items flowing for this platform sooner than later.

    Alex - I believe you're referring to the Vargas tuning thread here at BB. Someone posted info they'd sourced from a stress-testing company regarding N20 head cracking they'd discovered in testing at torque levels above 331 lbs-ft (wheels). While I can't comment on those numbers or how they were derived, I personally have knowledge of 2 head cracking occurrences on N20s which required complete engine replacements on both vehicles.

    I'm not going to speculate on the causes or whether its a widespread issue, but I do think this is something that we'll hear more about as N20 tuning develops and people put miles on their cars.

    How in the world do you not have a decent camera?!?!

    Phone and Ipad photos won't do this justice. I feel like mailing you a camera.

    LOL ... grab a rebel xs or xsi off ebay for like 300 with kit lense, its more than good enough..

    than shoot pics with a $100 cannon 50mm 1.8 lens and theyll look incredible... grab a $50 sunpak flash that swivels and youll be in biz...

    no need for anything better than that.. esp to display your projects, cars, work etc without a photographer on the payroll its perfect... or hire some smart high school kid once a week to do this all for u for $50 lol
