Step one: BOLT ON Tune up- ALL FI parts working Engine in good running condition K&N airfilter Quad tip plugs Quality synthetic oil for engine and tranny ADD Two: Bolt on Free'er flowing muffler ECU chip (If Digifant and 022D ECU) Sand smooth the inside of the throttle body (mine was rough) This minimizes turbulence through TB and provides a better seal butterfly valve. (Ken, that is why my idle screw was out further than normal)
ADD Three: Valve cover removal Ratio 1.3 rocker arms Solid rocker arms Swivel valve adjusting screws. Cromoly push rods Cut to fit. Match stock push rod length. Match port the intake runners to the intake port. Check exhaust that all pipes have no overlap at joints. Use finned aluminum clip on T1 valve covers
ADD Four: HEAD Removal Heads: clean up ports to eliminate restrictions keep rest stock ADD Five: HEAD Removal Cromoly retainers and racing valve locks 3 angle valve job on seats and two angle on valves Ceramic coating on sealing surface only ADD on the exhaust pipes, combustion chamber, exhaust valve, exhaust port Add Six: Case Split Add counterweights to stock crank Full balance of all rotating parts as a unit with pressure plate (If in budget get two PP balanced so the new one will be balanced to engine) Add racing crank spacer Lighten flywheel 3 lb.lbs ONLY IF counterweights are added Add racing clutch bolts REBUILD 2.1L rods WITH NEW 1.9L BOLTS ONLY Add Seven: Case Split ADD performance cam ONLY if adding ratio rockers (the increase overlap makes the engine lazy on the low end, but the ratio rockers counter that effect by increasing low end torque AND LIGHTER PUSH RODS) ADD low friction coating to pistons
ADD eight: Case Split Match port the oil pump inlet and outlet to the case and radius the inside of the inlet and outlet. ADD .457 SA five speed tranny for an overdrive 5th gear. Good VW shop that deal with performance T1 engines could build the WBX engine similar to what I did easily. After all, they do what I did and MUCH more to racing engines. When you look at what I really did was to make changes to two main parts crank and cam. The rest I replaced stock parts with better after market parts. The rest was just attention to details. What you choose to do depends on your budget
