I know that you can’t change much on the car for the MR2 challenge but have you seen the power levels the little 1.6 4A-GE lump produces in formula atlantic! see here - http://www.toyota.com/motorsports/atlantic/facts.html -and that’s nowhere near the ultimate level of tune:o
It’s pretty much a japanese copy of the Cosworth BDA.
They are truely awesome engines! I’m always very impressed with them, and for the milage too, they just hold together so well! (saying that, I think I’ll need some big end shells on that car soon!)
