civiccpedx

i was visiting a local performance shop and they told me that in order to put in a k20a2 into my 1994 2dr civic dx, that i would need to get a custom sub frame, and custom mounts because no one makes them.

also they said that i would need to replace my ignition system and "reflash" my key. (my key does not have a chip so i dont know why it would need to be reflashed.)

I am wondering if any of this is true, and if it is or isn't how much do you think it should cost to get the motor installed into my car?

also if anyone would know what do i need to put the k20a2 into my car, ie engine, tranny, ecu......axels? linkage? thanks for any help
