The 3 bar range is 0-100kpa vacuum and 100-300kpa boost, still 30psi boost is going to get the job done for most.
Really you could make 700rwhp on a basically stock LQ9 or LQ4. (just cam/springs/forced induction). If you want to be very safe about it then throw rods and pistons in any LS and it would make that power forever.
After running super reliable LS combinations for years I would personally never consider using a sbc or bbc again.
