OK I have EF sedan non vtec and my friend has a crx si vtec so is it possible for me to use his head and ecu since we have the same motor (d16a6) and make mine vtec??

 

SHort answer: yes, but with some mods.

Search for "minime" and you'll find the long answer.

 

if his bottom end is an A6 then yeah.
Y8 and Z6 heads will work fine.

little bit o wiring and your good to go.

 

so will a d16a6 vtec head work

 

i personally havent seen an A6 vtec.

but if it exists, then yes, its still an A6.

 

there is no a6 vtec head.

Your buddy has a mini-me head swap. he has the a6 block with a y8 or z6 head. you can do what he did and transplant it on to yours. you will have to do some mods to the wiring and get a vtec ecu.

 

yea im just going to use his ecu
