I'll post my 7M twin build information soon once I get it all organized. Just a little taste....
Just the engine setup...
over bored .0334 aprox
custom pistons
custom rods
custom cams ~8500 max rpm
custom ITB front facing intake manifold
custom exhaust everything setup
dry sump oil system
Sequential Twin GT30 series DBB turbo setup
custom machining - way to much to list
rear weight reduction for more stability when she's sideways
all of this = crazy fun to drive/drift
someone mentioned it before...if your willing to pay 5 figures plus and want a challenge...well thats me. Why not have a hobby and a supercar in one.
If your building a car for the track I understand big single. For everyday driving, its all about handling and acceleration for me.
