Z20GenX Integral Exhaust Manifold For Z20LET Z20LEL Z20LER Z20 LEH

Z20GenX Integral exhaust manifold for Z20LET Z20LEL Z20LER Z20LEH engines, the ultimate plug and play replacement manifold for all Z20LEx engines, it is a direct replacement for the original restrictive GM / Borg Warner manifold casting as all the pick up points correspond exactly to the original casting. 

The manifold is the result of an extensive development, designed and calculated using the latest CAD and CFD technology. Its is made with 1.4849 Stainless Steel with high elongation at break, this makes the manifold temperature resistant to 1100 degrees C.

When used in conjunction with the original  K04 VXR / OPC  turbo it will provide 30Bhp more power over the original GM manifold. Furthermore it will finally unlock the full potential K06 or HTA and other hybrid Turbos. 

Further development using a KRS Stage 3+ 16 Turbo is has been under taken and we have seen power figures of circa 400 Bhp
