Lol.
First, this motor makes 330 on the dyno. Second, it's about 1/10 the cost of an S14 and , well I just told you it's over 100 hp up on the old ass M3. I used to have an E30 M3. I put 5 K into it and then it rewarded me by making
138hp
at the rear wheel. Wow.
The timing belts do fail if they aren't replaced but so do the new M3 motors with SMG, so do the S14s without the oil pan baffle. Every engine has problems, nothing's perfect.
The stock 4G63 makes 187ftlbs of torque stock, the M3 makes less than 150. The M3's undrivable on the street and rewards you only at the track. Turbos are more forgivable and you can get faster corner exit speeds with the extra torque.
" they seem to be crappy engines"
Well, you seem like a real expert so I'll take your word on that, especially since you're replying with such intelligent posts and not using sweeping generalizations that are completely unfounded.
FYI- My friend Mike has a galant vr-4 with the same motor that's in my car and he runs in the 11s. It makes over 500hp at the crank. 250hp per liter versus the precious S14's 100bhp per liter.
here's a link to Turbo Magazine's Galant tuning article.

Bottom line, that's cool that you think it's rice. Thanks for telling me what I should or shouldn't do, and also for representing the entire BMW community, insulting forum members intelligence by saying that BMW's "aren't meant to be top performers" and for entertaining me on a rainy day at work by providing me with low hanging fruit which I can grab and make you look silly.
