Also the MIVEC is only on Evo 9s and is fairly useless past 500hp. I know this because I have a buddy whos Evo 9 MR is currently at Buschur Racing in Ohio getting a Built 2L engine, PT6262 (although he has a HTA86 on order), complete 1000hp fuel system, advanced ignition system, Shepherd Stg 3 trans and transfer case, and drag racing coilover setup. He should be turning about 700hp on 93 pump. He is running a 280 cam and they can't advance it very far and barely makes a difference in spool or power. Some people even disable it.

funny.....

The fastest stock ECU EVO is an EVO 9 with mivec, it is also the fastest on drag radials. 8s on the stock ECU, 9.0 on drag radials
