from a 2 valve head with a 2L bottom end? the highest hp NA i seen is 163hp at the wheels, this was a 2L escort that rev to 9500rpm. i'd like to to see a L20 rev to 9500
2.0 Liter Nissan L-series Built January 2002 By Paul Snelling (@Robert Yates Engine Development) Approximately 250 bhp @ 7,000 rpm SSS cylinder head prepared by Gerolomy i see he say approximately. plus he say 2.0 litre. not 2.4L just my 2 cents.
