colder plugs for turbo??

what's up, i was thinking today, would it be possible to put the Echo VVT-I head on a 5efe? i looked at some specs and the bore was almost exactly the same between the two. i just thought it'd be cool to have vvt-i on my tercel. Also why is it necessary to use colder spark plugs in a turbo engine with smaller gap? may sound stupid, but.....

All the people I know with turbos applications have never spoke of colder plugs. Nitrous applications are a different story.

the colder plugs will prevnt themn from getting so hot, that once the fuel is sent into the chamber, it wont ignite before the spark is given. if it ignites before the spark is given, this is because your plugs are so hot that once fuel touches them in the chamber they ignite at the wrong time in the sequence.thus causing poor pefrormance.
