Toyota MR2 Message Board - View Single Post - Getting power from a 5SFE without forced induction

I think some may be missing the point... please read the first post again.

We have seen time and time again that if you start with mild cams you will have mild results. Get the cams to match your goals and build everything else around them. This is the trap that the 5sfe community has been in since the beginning. If you start with cams that can't outrun the fuel system then you will never make more power then the fuel system was designed for. Unfortunately that means you have to make a leap. You must upgrade the fuel system at the same time you upgrade the cams. That is what the performance build is. Once you make that leap all of your other mods will have more effect and it goes up from there. Now someone might be able to hit 150rwhp with the 294 cams but it is going to be tuned and it will be a lot more work.

By the way Kentsvison's mod list included tuning with a piggy back and larger injectors.
