But just no. It just doesn't sound right. Sorry gav. 😏
No need to be sorry, as much as I like the idea I just couldn't do it to my own S30s as I prefer the period correct feel myself.
If I was going to do a 20b or 4 Rotor swap I'd put it in my FD rx7.
I think a 4 Rotor is overkill anyway, 20b is plenty for a street driven car. 4 Rotor does sound glorious though.
