well 87 is a year of the forged trw pistons sooo up grade exhaust underdrive pulleys , some fuel stuff , cai and a 100 shot and smile at your low 13's slip

ohh btw nittos or drag radials are a good mod for street or track and gears with the autos wake them up a bit also . so what do you plan on doing with the car?
btw if you wanted a t5 I have a friend with one for sale.
