The only way, I would put a 35R on a evo would be with a stroker and head work. The information posted on this thread only confirms my thoughts.
Listed below is a quote from Martin @ AMS about their stroker & their 35R kit & how it spools up compared to stock:
Quote: "We just ran the car at 24psi with water injection and made 501whp and 430ft-lbs of torque. I did some road tuning with this car the last few days and it will start making boost at 2200-2400rpm with 10psi by 3K in 4th gear and 24-25psi by 3500-3600rpm. Awesome car to drive with a very wide powerband, perfect for the street or road course. You have full power and torque from 3500rpm to 8000rpm. Where the stock turbo start to drop power at 6500rpm this thing keeps making power all the way to redline. To compare power bands, the stock turbo hits full boost at around 2.9-3K rpm and makes usable power to 7K rpm, the stroker 35R setup hits full boost at 3.5-3.6K rpm and makes useable power to over 8Krpm"

In my opinion, if you are looking for a streetable set-up with not as much lag, this is the only way I would put on a 35R.

Well i dont know your whole entire setup but that AMS Evo has a fully built bottom-end and not only that but i think he's got about 2500 in the head itself so with the head work it would flow alot better to in wise would spool the turbo faster.

Frankly, rather than seeing time to target boost, I'd rather see acceleration "elasticity" data collected. Time some runs taken to achieve real world acceleration tasks (25-50mph, 50-75mph, etc.) in each gear. As long as this is done on level ground it's a much better comparision and will more clearly illustrate the tradeoffs of each turbo configuration.

The VSS is not really that great in the ems...but it might do to get some rough data. And I don't know if any of the other datalogger/engine management setups can log VSS.

Additionally, if the tests are done in a specific gear then RPM can be used to calculate road speed. Assuming of course that the overall tire diameter is standard from test to test.

I had the same problem at high RPM with boost. BPR7ES gapped down to about 24 will do the trick. It seems to be fine on mine to about 28psi. (that's all the psi i've run thus far)
