Agree, the Hpfp on the 2.3 is a different set up and the cam has four lobes not three for the Hpfp, I am speaking to a few people about an upgraded fuel system hence the comment. Will let you know

The ATP Gtx setup looks horrible, I'm not a fan, so I will be making things up from scratch. Thought about a 7167 twin scroll but have the Gtx so will use that.

The USA tend not to track the car just 1/4 miles so I was shooting for 400bhp crank on std internals and see what happens.

Thanks on pcv
