I can't tell for sure. I'm squinting at his picture, but the heatsinks for the T3.0 and T-15 are very similar. It's either an Evo or an Evo+, the difference is in the motor and tuned pipe. Ask him for a picture of the other side of the car, or just a higher-quality photo. I had the Evo, which has the weaker of the two motors, and it was still quite fast. I'd ballpark 40-45 MPH.
In either case, I think $150 is a fair trade value/price for it. $200 is borderline for me, but I'd probably do that trade if I were you.
