if i put vtec on my stock 00 crv awd automatic b20z how much would i have to upgrade. i mean my car barely revs up to 7k so there's not way ide even get close to 8k would i still need to upgrade my pistons and all internals??

thanks all!

 

also since its auto would i just be able to grab a auto gsr ecu? would that affect the awd?

check that thread has almost all the info youre looking for except for the whole transmission part. My thoughts are that the juice isn't worth the squeeze on a auto. doing this thing right isn't cheap.
