Depends on the condition of the motor, but off the showroom floor around 400ish.

400'ish with a good tune!
The only way to get there is with a blower, or a lotta n2o!

400 is what im hearing on this site...but yes like above it depends on your motor as well. its also good to get a compression test done too when you get a car.

I would say less than 400. 400 is usually the number with a safe tune on a PI car. To get to 400 on an NPI car it is going to take more boost or more N20.

I said 400 because the pistons and rods are generally the "weak link".. I believe the NPI blocks have the same hypereutectic pistons as the PI blocks do.. just different heads/cams, etc

ok well i got 300ish hp right now with the motor. it dynoed at 268 rwhp. the motor is great shape. just rolled 80k this week. i got ported pi heads and pi intake with the pi cams. i havent tuned the car yet but im gonna need to cause its too rich. i smell the gas everytime i come to a light. i plan on going the turbo route so i want to make sure i dont mess anything up. but i do plan on buying forged internals just want to make sure my block is gonna hold up. dont want to crack that bastard. so 400ish at the wheels is about what it would take???
