THe Batlground header, or even the one we sell, will NOT support 300whp. Youll need a custom Hytech or SMSP tailored to your setup.

The Cams you need to run are Skunk2 Stage 3s, or IPS KMEs

You need to run a K24/K20 Head motor (2.0l just wont do it without MAJOR money)

ITBs arent a NECESSITY, but they are nice to have, that or the IPS Manifold if you can get one

You got about a $15,000-20,000 MOTOR staring you in the face good luck. 275-300whp in a street car is honestly way too much, mild K20s make 230whp, and depending on your chassis, thats PLENTY of power
