Review
Jons R400 rebuilt in 2007 for less than 2 grand, with one off EN24 KingK flywheel. Engine not blueprinted, simple OE rebuild, run at rollers with 40 miles and 15/W50 oil. Would expect another 4% with light synthetic oil. Same engine as Sean Bicknell, but no messed up install, dodgy wiring loom etc however induction interference with OE ITG intake filter hard up against inside of bonnet which was not cut to free induction.
