Very hard to guess, as it'* too far different from the S2 L67 to compare. And the HP isn't where she shines. It'* the torque that blows me away.
Let'* take it backwards a bit and try to figure it out:
Gen3 swap came later, but we'll use that 225hp 260tq point to start with, then figure in the rest.
Jet Stage 2 PCM (10hp? enables other mods)
Magnaflow Cat and ceramic PEM'*? (mostly allows smaller pulley, but call it 10 hp total)
CAI with ram-cold feed (5hp)
SC pulley typically nets 25hp/40tq for the first step, each following step is smaller. (35/50)
Flowmatched injectors (yes, this adds power, 5-10hp calculated by FIE)
How much for my porting/polishing on the TB, SC, and LIM? 20hp?
Plus a trans with 5% less loss than a new OEM trans (gauranteed).
My guesses based on the Mod list in my sig (not up to date) probably put me close to 300hp/350tq at the crank, 20% less to the wheels. But my car will run at the track slower than a S2 with the same numbers because of WHERE in the RPM band I deliver my power. I'll beat that 300/350 crank S2 L67 to the 1/8 handily, then they'll run me down.
Play with the numbers a bit. I'm game.
