Tuner Tuesday: 1989 Porsche 911 Carrera 4 Turbo RAUH-Welt Begriff

Last week: Gemballa. This week: RAUH-Welt Begriff. We might as well look at something from the two most divisive Porsche tuners in back-to-back weeks right? I said in last week’s post that I don’t mind over the top designs from tuners and along those lines I typically enjoy the work we see from RWB. While many don’t like them, Akira Nakai’s builds do follow a line that is recognizable within Porsche’s own racing designs. Of course, those are purpose built race cars and RWB builds street cars. None the less, the look itself is not necessarily off base.

And here lies the primary criticism of many RWB designs: they are all show and no go. For many, in fact most, of their builds that is true; RWB focuses much more on the appearance of the car than on making it faster. This build addresses that criticism, and it addresses it pretty significantly.

This 911 began its life as an early 964 Carrera 4. We’re even provided pictures of it and it looked pretty good! Still, the transformation is pretty stunning. But enough about the looks because you’ll either love ’em or hate ’em. As I said, RWB typically is criticized for being all show. Not so here as this Carrera 4 now packs 400 hp at the wheels thanks to a single turbocharger and a fully rebuilt engine. For comparison that’s more power than Porsche’s own Turbo S produced. It’s probably at the wheels than a 993TT. Will it feel as seemless and functional as those factory versions? I would be pretty surprised if it did, but at least the power is there and with a set of 993 Turbo brakes and calipers on board reigning in that extra power should be doable as well.

I don’t know that this would make a good track car. I’m not sure if it even is intended to be one despite its looks, but within the street tuner world I’d imagine this RWB attracts a lot of attention and unlike other builds it does have the power to go with those aggressive lines. Like every other RWB car I’ve seen the asking price is high, though this one doesn’t seem any higher than the others. So if you’re an RWB fan and you want both performance and looks, then this one is probably the way to go.
