My total was $154.35 including $32.75 for overnight shipping (I bought 16 of them to have a set on hand if I need them again. Sounds a lot cheaper than your guy
Edit - ps pump replaced and also new timing belt, SC belt.

Yes, it is usually recommended to do this although until today I didn't really ask 'why'. Mo said that a higher heat range plug (such as stock) can cause pre-ignition and detonation in FI cars.
Too cold of a plug is bad too. Say on an na car, something that rev's pretty high can get away with it tho (ie: intergra type R).
Roteries run really cold plugs.
Heat range 7's are fine for most FI cars.

You are 100% correct.. I'll tell my story once my new motor is built.

id like to modify the RMM setup and have it run off the crank as well
i was never really fond of the RMM setup running off the PS pump
have you encountered any problems with the srt setup
from all your old posts it just seemed like power was the intial problem
and that was taken care of (420rwhp)

As for any other problems, I would change the setup to use a ribbed belt given the resources. Just so much less to worry about.

No problem johnny!
I think there are one or two other pics in previous posts that might give you an idea of what the full system looked like but in any case If the pics aren't a rush I can post a decent collection in a week or so. Otherwise I can see what I can rustle together tomorrow.
