Hi all I've been absent for a while. But I have rekindled my love for my car. I have bought a power fc for it but I need it mapped. I also have a stainless japspeed exhaust manifold to put on. But I don't know how to tell what flange it is. As I am looking to upgrade my turbo. Can anyone help with this. They guy I bought the manifold off said he just bolted the standard turbo onto it.
