I am feeling ambitious, so I'll compare it to the ZR1, which can rocke to 60 in 3.4 seconds. I am going to assume that curb weights are dry, and guess some values for driver weight and fluids; 270 lbs for the Corvette, 260 for the 818.
base coupe Z06 ZR1 818
curb weight: 3208 lbs 3175 lbs 3333 lbs 1800 lbs
total weight: 3578 lbs 3445 lbs 3603 lbs 2060 lbs
power: 430 hp 505 hp 638 hp 227 hp
lbs per hp: 8.32 6.82 5.65 9.07

Well, with a stock 2005 WRX engine, the 818 is toast. With some modifications, though it could be faster. To match power ratios, the Subie engine would need to produce at the crank, 248 hp for the Corvette base, 302 hp for the Z06 and 365 hp for the ZR1. Tuning the little 4 cylinder to compete with the base Corvette or even Z06 should be fairly simple. To catch the ZR1, your going to need deep pockets, and probably a heavily modified transmission, so you would probably be better off starting with a GTM.

Some of the other factors are speculative. The corvette will have a better power curve, not suffering from turbo lag, and will have some computerize traction control. A good driver can make up for some of this. The 818 will have a big advantage, however in weight distribution. The Corvette has a 51/49 distribution but the 818 maay put around 65% of its weight on the rear wheels standing still.
It better not have 65% of the weight over the rear! I'm guessing around 55%.
