Performance Modifications

Stage 1

HYDRA ENGINE MANAGEMENT this is a plug in aftermarket Engine Management system and wiring loom, developed by ZCars for their V Tech kits.  It comes complete with its own wiring loom which only then requires 12 volt feed and earth to make it run.  With the standard kit exhaust and silencer, the results are a 10% increase in top end bhp to 220 but the real gains are to be found in the mid-range torque.  This is achieved by careful mapping of the VTech system and operating it earlier in the rev range, something that other systems struggle to cope with. ECU and LOOM complete

Stage 2

Four into two into one stainless steel performance exhaust manifold gives another 15 bhp if used in conjunction with above HYDRA system

Stage 3

46mm individual throttle bodies and inlet manifold increase power by a further 20bhp to give a total of 255 bhp

Stage 4

Supercharger Kits available tailored to suit your needs. Up to 400BHP and 275 lb ft. torque
