You want to run that by me again? I own an 07' Accord with a V6 and 6 speed manual, and it will tear your Prelude a new hole any which way on Sunday (and every other day of the week), and it gets better gas mileage than my 91' Accord did with a 4-Cylinder and half the power. Honda's V6 is one of the best engines they ever made...
Oh, and your high compression results most likely aren't from a high compression rebuild, they are from carbon build up over the years...
No offense, but are starting to sound like an uneducated fool, especially since the B21A is probably one of the worst engines Honda made as far as performance goes. FRM sleeves that very few machine shops can bore, no parts commonality with any other engine, likes to burn oil like crazy, etc.
