VW Golf with over 500 bhp from a 1.8-litre turbo engine!

Water/methanol injection is used to keep temperatures under control during high boost conditions. Maximum boost was at 38 psi!! ... See moreSee less

TVR V8S Chassis Restoration - this one started out with serious corrosion, including big rot holes in the main chassis legs and transmission tunnel tubes! We cut out and replaced the metal, including both outriggers with thicker cold drawn seamless tubing, before shot-blasting entire chassis and finishing with 2K etch primer & 2K top coat in original colour. ...

How reliable are these rover engines with the wildcat head? My 5.0 had to be rebuilt at 30k!
