Where did you hear that the handleing was negatively affected with the RB???? i had the ZR200 mounts and my car weighed out at 51 front and 49 rear and handled real well. i really didnt knowtice the difference between the old l28 and the rb except the tires spun alot more
I amagine some custom mounts putting the motor as far back as possible you could reach the 50 50 wieght distribution easily.
And BTW you will need a turbo, and intercooler upgrade to get the vg to the same power level as the rb26 with just injectors and turning the booste up. throw upgrade turbos on the RB26 and you have to go into the vg to get the same power the rb puts out with just a turbo upgrade.
Just my 2 cents. The vg swap has been done by a couple on this board. they are both decent swaps and if your looking for a economy swap ( well you know what i mean) go with the VG as there are parts in junkyards and avaiable at your loca parts store. With the RB you need friends in japan willing to send you parts when you need them
