I'm assuming this is on an EF rwith a B18a swap?
Here are some things you might have to do or you may want to think about doing:
-relocate battery to trunk
-get a traction bar for downpipe clearance (ie. Full Race, Lcon, etc)
-get an EG halfsize radiator (depending on your manifold setup)
-you can upgrade the fuel pump now while you are still NA
-install a clutch that can handle the extra HP/TQ you'll be making
