One car that we currently have in the build is an S13 Silvia running an RB25, with a Garret GT 30/40 Turbocharger, blowing through a r32 GTR cooler and PFI intake manifold. The engine vitals are all controlled via a Haltech PS2000. The power is layed down through a R33 GTS-T gearbox. The braking is controlled by R32 GTR brakes front and rear, complete with 5 stud conversion. The interior consists of a bond roll cage, and a race seat, keeping is simple an functional. R33 GTR wheels sit tucked under the wide body.
You will catch this S13 at the track very soon.
