If you take the cars year for year this is what you find.
1991 MR2, 2.0L Turbo I4, 200hp 200tq, 14.5-14.7 stock 1/4 mile times.... Cost brand new $21,000
1991 NSX, 3.0L VTEC V6, 270hp 210tq, 14.1-14.4 stock 1/4 mile times..... Cost Brand New $87,000
So, its not very fast, and you can own 4 MR2's for the price of 1 NSX.... or you could have bought the MR2 to play with, and still had enough money to buy the brand new 2006 Z06 Vette with 550hp and 0-60 in 3.6 seconds.... 11.7 sec stock 1/4 miles.... the fastest American Car stock... And yes I know the Ford GT is fast, but it doesnt beat the vette and the Ford GT isnt mass Produced....
