Motor is being built for my 08 evo x gsr. Sleeved 2.2 motor. Fully built. Was looking into the ef4. What numbers have you gotten? Any numbers on race gas? I'm deciding aether I want to go with this or something else. I'm going to road race the car some so I want something that won't have much lag. But I wanna be able to make some mad power because my motor is built to handle it. Please give your opinions. Thanks.

 

Murlo and Scheides are two well known members with an EF4X.

 

That turbo setup must produce some nice numbers....

....Ya know because it can't be just bad luck blowing up Murlo's engines



Had to take that opportunity Murlo
