I am watching reruns and seeing this episode today. They are changing injectors, ECM, the turbo, Boport cam and intake/exhaust system and adding an intercooler for more power. Anyone else see this?
They put it on a dyno and it did 278hp with the mods. Cool.

That's it? They should have gotten some help from those dudes over at PM Motorsports.

That episode's been discussed before. Stinger talked about it a little at TurboFord and the bottom line is they didn't have the time that they really needed to work through the build, so there was a lot left on the table.

I really wish these things did a more incremental approach... the whole kitchen sink approach is fun and everything, but I wonder how much of that +100hp came from what upgrade. I remember a conversation with a Saab engineer once and he admitted they could get +50hp from an '80s Saab motor with just ECM work and a turbo and no additional boost. I would not be at all surprised if a Lima was in the same boat.
