Need help with this build. When winter hits I'm planning on taking the motor out for an engine build. What would be a good parts list for an ap1 without overbore? I'm hoping to hit at least 260whp. Will be getting an intake soon. Jus dunno which one to get
As of now I got emange ultimate. Skunk2 megapower header. Skunk2 70mm test pipe. Skunk2 megapower exhaust. Skunk2 alpha 70mm TB. And bc stg 2 cams.

 

AEM and mahle 12,5:1 pistons.

 

With out some serious $$ and some better cams you wont get close to 260 with an ap1.

There is no off the shelf intake that will support over 220hp

easiest route to 260hp is to build a 2.4liter motor.

 

Is there a build guide that you could show me to the 2.4 build with part list

 

You're definitely going to need a 3.5" intake that's the proper length as well.

 

Damn so I'm gonna have to do alot of custom work

 

K20/k24. Sell your motor bone stock and sell all your parts.
