[DML] Re: PRV Performance - Set me straight please

["Matt Spittle" <supermatty@xxxxxxx>]

Rick,

I've spoken on the phone with John Lane from Pacific Rim Automotive 
(http://www.pacrimauto.com/) about these sorts of things, and I must 
say, the man is a genius when it comes to "upgrading" your PRV.  
He'll have all of the answers to these questions before you even ask 
them.  He is the man who developed 500 HP from a PRV, BTW. 

My thought is that he'll tell you to go get a Volvo 760 GLE 2.8L 
engine, and bolt the eagle premier heads on it, along with the DMCH 
headers (they do sell them separate, don't they?).
