well if you dont want it to be a torque monstor by a proper boost controller and have low boost in lower gears and have it set high once you in third and up!

i ve had a cvh and it pissed me off havin a lot of lag due to a bigger turbo it was all or nothing! my fault for puttin it on!

with the zvh it there straight away! all the way through to the rev limit of 7200!

as for rods and pistons they are quite redily avalible! granted not as easy as the cvh but then again the zvh conversion aint a standard fitment that every piston manufacters caters for!

bhp sells engines! torque makes a fast road car!
