13b RE COSMO Style design and port sizing internally, we’ve made the engine ports on the lower match an FD/REW engine due to there being larger volume of them on the market and mor e parts still available for them. However we have already developed a CNC port program for those running a Cosmo block and/or after market billet plates with those port sizes. Additionally we have built in Semi PP ports that remain blank until you need them instead of needing to sell your lower and purchase another . * BOSCH DBW adapters and throttle kits available * Additionally 1/8 NPT vacuum ports on the upper manifold and a 1/4 NPT port for your brake booster on the lower. * billet fuel rails which will come with the inlet with fittings and 2 blank injectors as standard with the kit for those already running 4 injectors only and just wanting the inlet upgrade. suits cosmo throttle body but with small mods will fit fd also * Upper and lower manifolds * Billet secondary fuel rail with fittings * X2 injector blanks * Assembly hardware kit * O-ring kit * IAC valve gasket Show more
