It will be interesting nevertheless to see the limits of these engines as good tuners work hard to extract the safest power out of them.
Picus - what is the boost / afr on the V2 ProCede?

^^^I agree. Can we get a damn chip like Audi? Now make no mistake, the Lexus 3.5 with dual VVTi is the strongest stock 3.5 engine out there. However, there are those that would like some more power.
It doesn't feel like its near out of breathe at any time. I am sure there is an extra 50hp in there easy.

We already have some hints of the engine's potential. Tom's supercharger gives a nice HP boost. Blitz has a prototype supercharger that pushes HP to over 400HP. Then of course we have the IS350 GT2 cars that were never raced. The 2GR-FSE engines in those cars though make over 470HP naturally aspirated.
With the UZ V8 engines for example, there are plenty of mods out there and more mods continue to come out everyday. The UZ is an old engine and it's mainly been figured out, which is why only now are we fully seeing the potential of the UZ engine.
When tuners figure out the 2GR, then we will really see it's potential.
Keep in mind you're comparing FI vs. NA cars here. While the N54 335i engine is formidable, it still isn't on par with the best from Japan yet, in speaking of comparing against RB26DETT, 2JZGTE, or even older 3SGTE / VG30DETT. Heck, this 120hp gains (don't look at the dyno numbers, look at the delta) isn't that impressive when you consider that a Mitsu Evo 9's 4g63 can output something comparable sans 1.0L, 2 cylinders, and 1 less turbo.

Good point. As for the whole iron block vs aluminum block argument, it's not a big deal. The twin turbo V6 in the GT-R for example is aluminum block, yet I'm willing to bet that engine will be stronger and more tunable than BMW's N54. In stock form, it's already making much more power than a stock N54.
I need to read up more on the N54 in terms of fuel specs, cylinder designs, valve / cam specs, etc. Just been to busy, but it is still my top choice to replace my Evo...

Agreed, the 411BT in the Evo X is saving 23 lbs over its older 4G63 counterparts. I think the main thing to keep in mind is the block configuration. Honduh's had open deck designs that were susceptible to imploding without the block guards. New designs are closed deck and can stand the high cylinder pressures of boost.

If the interior was more like a Lexus or even a Benz, then a 335i coupe would definitely be my next buy.

Oh, and fwiw this was AA's recent post regarding the PROcede hitting 400hp (on an in house car)
"The turbos on a 1JZ are much larger than these 335 turbos. You can make over 400 rwhp with them. As of right now we are not going to be develop a map to run any higher boost. Honestly if we can ran 16 lbs then you would want a map with 20 lbs. You cannot compare a BMW 335 with any 1JZ or 2JZ Its life we all want to get more and more.
We ran over 14lbs of boost and the turbos were clearly out of their efficiency range, they barely made any power over that amount so it did not make any sense to push the limit."
Someone asked them why they couldn't make the power a 1JZ or 2JZ, kind of nice to see a sensible answer on that. Over 14lbs of boost on these tiny turbos is nothing but chest puffery, as far as I am concerned.
