actually a BONE stock DET with stock exhuast/boost is a really slow car. My friend has a S14 with a DET and it's a monster on 3" exhaust/14 psi on the stock T25. He detuned it cause he couldn't take the loud droning of the exhaust and i raced him in my civic. I walked him HARD, i'd say they are about as fast as a stock prelude bone stock on low boost.
