It does not really take much to make 250 whp area. I've had oem VT brought to me that made 182 whp and 2 days later and less than 2k invested make 250+ whp. 300 whp takes approximately 3x that much to achieve.

With proper mods, fuel, and tuning, 250 whp is an easy feat. With your mods on 91+ octane fuel and stage 1 Qwik Tyme Performance tune the car should make 230's-240's whp with avg intake air, coolant, and exhaust gas temperatures. Better mods and/or fuel and/or colder air it will hit the 250+ whp mark. Right now on the oem tune the car will probably make 205-210 ish whp max in good air with good fuel then the limiters will kick in at higher rpm and pull 15-20+ whp out of it.

Mods for better air mass and/or knock suppression.

The cheapest and safest is a good wmi kit setup properly.

Cost will vary based on what is in the kit. Generally a basic progressive kit will be $600-$650 and can go up in price from there based on what may be added to the kit. Most cars are ok on the basic kit though.

Some turbo lag is normal but it is very little on the oem turbo. Below 3.5k rpm on the gen 1 VT do not expect as much response/boost/power as above that area.
