I have a b16 rex and I'm taking it to the track in the next few weeks. I'll have it completely stripped, open header, race fuel, and either 65 or 75 shot of zex on it. It'll also be on slicks. The car has a stage 3 clutch, other than that the motor is basically stock. Just wanted to know what you guys think it would run.

My friend ran a 13.5 with intake, header, full exhaust and a 55 shot on street tires. So hopefully i'll be in the low 13s??

 

It's hard to say without knowing variables such as elevation, track condition, air temperature, and of course, driver skill. I'd say mid to low 13's are possible however.
