Here are my plans:
-Spoon 2 ply headgasket
-usdm itr pistons not sure if i should get standard or +.25mm.I want 2 raise compression to at least 11.5.1
-portflow valvetrain
-skunk 2 intake manifold-Do i need to buy a itr intake system?
-skunk 2 stage 1 cams/cam gears
-apex i super vtec controller 2
I want to gain at least 30 whp in powerband.I want midrange to high range power. Idont really need to raise the redline,by up to 9 rpm would be great.
Iwill daily drive and want to be able to pass smog with reliabiltity.
