Just because its done quick, doesn't mean its done right. On top of that, not everyone can afford to buy every single part all at once and be ready to install it all.

Sov put a ton of thought and effort into his build, which is why it took so long.

 

There's way more to building an engine for performance than to just tear it out and slap new parts in...I'm rebuilding my B204 right now and I'm estimating about 3 weeks all said and done after machine and finishing work. That includes me taking out a vacation to work on this. If I was doing a simple rebuild it would take me may be two days at most including waiting for odd parts overnighted to me.
