I´m considering trying the GO engines and I have been using a OS V-Spec and I´m satisfied with it but I would like a more mellow/controllable bottom.
It hits like hell on the bottom.
I´ve tried a couple of my friends Novarossi +4 engines with the exact same car/setup as my car including the same clutch-setup and damn it´s a nice engine... Smooooth and fast with good runtime.

Should I try the GX-3R, GX-5R or GX-7R if I would like an engine to perform like the +4?

Thanks for your time.
