For now I'm relegated to making vroom vroom noises in the garage (which do sound more manly with the V8 under the hood). I just picked back up on the project yesterday after having to set it down for the last few months.But the V8 sound has to overcome any of that! I am leaning toward the R2.8 just for fun, but when the time comes I may just follow your thread since you are/have figured out most of the drive train!
