there is a bit of info here on this engine, what i know is thats it around 141hp at the fly, the turbo has a metal shaft, the airflow meter is very restrictive (about the size of a matchbox), they seem to be very unreliable, i have one (l20et) still with the gearbox just sitting in the garage with the entention of putting the head on to a hatch l24e i also have sitting there! i'll get around to that one day! there is a thread here somewhere that has the specs for the l20et, also theres either a HPI or ZOOM mag in the last 3 to 4 issues that has all the specs aswell! HP/compression/torqueand other things.
