That's not a 10s car... Even at 28psi, he would be MAYBE in mid11s... To give you an example, a friend of mine have a 96 Accord H22 Turbo, a 2door coupe. He's running between 25-26psi and his best is 11.46@139mph... That's a 5th gen, less weight than fatty 6th gen and with 28inches drag slicks...
Important: i'm sure the guy don't have the right engine mount for driver's side. Take a look closely... engine isn't straight... If you look at the picture, engine must me parralel with the front (where the radiator is), but this engine isn't straight. It looks not so important but don't forget that an engine bad-mounted like this one will result as broken axles because axles won't work correctly. Specially with a near 600hp car, you DON'T want a broken axle on the lauch of a race resulting in a control lost in the concrete wall...
Be careful if you plan buying this car...
