how could i put a vtec head on my 91 prelude and what else di i got to change

 

what motor do u have? i think its a B20 but not sure.

 

yeah

 

That kind of b20 is not the same as the b20b/z in the CRVs.

I've never read much about them, but from what I understand it's not a B series as in the dohc vtec heads bolt up with some work like the crv motors.

I'm sure someone has done it, even if it was pointless or cost a ton.

Most people consider those motors hopeless and swap. Maybe someone in hear knows a little trick about them and can help you.

 

yup those B20's arent the best for a frankenstein. your better off just buying a crv block and putting avtec head then using you block.
