GA16de can make 118hp atw with bolt on mods which is equivalent to an SR20DE

A QC18DE can make 175hp atw with bolt ons including cams and 185hp with extrude honed manifold, bigger TB and air intake.

All at under 7500rpm mainly 7300rpm.

They are underrated engines with narrower heads for better valve angles and ports like late bike engines.

PJZ peter is campaigning this engine soon in SCCA and says the weight is equivalent to an A15 still remaining compact overall.
