I use to have an R31, Skyline Silhouette. was the best car so much power i've heard of guys running turbo's on these cars and apparently you can get some good power out of them. the motors are very strong.
I've also owned 2 Twin Cam Corolla's 1986 Model, these cars are so much fun to drive i smashed through a bunch of parts though.. not the strongest of cars
R31, is my recommendation. but buy the Silhouette. better seats and other options
