My 16v has a vey similar engine which has covered about 28,000 miles since its rebuild, been bored to 1.9 , ported, polished lightened and balanced etc. with a full magnex system and a K&N filter.
It put out 157.8 bhp on TSR's dyno which is 2.5 bhp more than it made before the magnex exhaust was fitted.
Quiet happy to be 20ish bhp up on standard but there's a few little bits and bobs I'll do to it anyhow
