Ideally if it's a rally car your putting it in, it'll need rods and a crank, pistons, valves, valve gear (buckets,shims etc), cams, light flywheel, dry sump and a twin paddle clutch..throttle bodies, roller barrel slide injection or carbs, then a decent managment system DTA, Emerald for fuel and ign or ign only if your doing carbs.....

The majority of the power is realised from the head, along with geometry modicatations to the bottom end. There are many well known and some lesser known people that are expert in N/A yb's. Paul Gardner has years of N/A YB experience and his engines produce really good power, Dave Brooks is another, I have a Gardner engined car in the workshop at the minute on on slide injection, 2.4 producing in the region of 265 bhp, this is slightly de-tuned from the maximum available but is bullet proof and has never given a minutes problem.....very capable of winning its class in the right hands and sounds awesome.....
