So there's a LOT to think about here. I've had a VG30E (single cam) in my 510 for about a decade, maybe slightly longer. I've gone through a lot of different set ups with the motor.
The VG30DE is a HUGE engine. Very big. The DOHC heads and intake manifold take up a LOT of real estate. If you do a VG30DETT and add the twin turbo's, you'd better have a lot of room available. It's a big, and rather heavy, engine. There's a reason why there's only one VG30DETT 510 running around here in the US.....it's very complicated. He has been working out the kinks on his swap for 4 years. There's a VG30DE 510 running around as well, but even the non-turbo engine bay is stuffed. The VG30DE puts out 210 hp stock, and there's not much you can do with it unless you dump a pile of money into it. So if you have a LOT of room available, and are ok with the 210, than it's fine. Also remember that the VG30DE was only sold in one car, so finding parts is not super easy.
If you're open to ideas, check out the VG30E and VG33E. The VG30E was offered in probably 8 different vehicles, from the Quest minivan, to the 300ZX, to thePathfinder, and Maxima. As a result you have a pile of different intake and exhaust combinations to play with. If the first one doesn't fit your car, go to the junk yard and get a different one. The ECU's are also a lot easier to find. It's also much easier to find alternator brackets to fit your application, you can move them left to right, or whatever you want. With the DE motor you're stuck with the stock location. Different pulley setups are also available for the E motor, from single V belt, to 2 and 3 belt, all the way to the flat single belt on late model cars. They both make about 180hp stock. The reason the 33 makes the same hp is because of the cams and it was designed with dished pistons to make it a non-interference engine, the 30 engine is an interference engine. Throw some flat tops and Z cams in the 33 and you'd be nearly at DE power.
Now if you want turbo, you can get 300hp *easy* out of a VG30ET. They make so much power you can spin the tires in 5th on the freeway. I've been in a VG30ET powered 510 and it scared the crap out of me. So if it was me, I'd throw in a VG30E, get it all done, and then if you decide you want turbo someday just drop in a turbo block and call it done, all the mounts will already be done from the n/a version.
I'm in the process of building a VG34E engine for my 510, which will have more power than the DE motor, and be a lot smaller.
