Where has stilson been? (non Subaru racecar build)

I think if I do the SR swap it will be naturally aspirated. It's already hard to get traction. The SR swap would be more about weight reduction and distribution, getting rid of the heavy iron blocked B mill.

The other option is NO2.

Understand fully. #1 son has an S13 Silvia with the SR20-DET and it goes like a shower of you-know-what, but not lighting up the rears is a bit of a challenge.
