as for your engine conversion

i got a b16b in my car and i'm on my p's

car originally had a d16a8, due to less than 10% displacement increse they didnt even look twice at the fact the motor was vtec, the transport dude came out, checked the engine number went back inside signed it off and bobs your uncle

but if you had a 1.5L they might question it, she asked is it the same capacity and i went yep 1.6L dohc to 1.6L dohc *cough* vtec and they said its fine
