Its 2 to 3 times the length of Mikes one, but would work better, as using a centrifugal one like Mike did is an utterly retarded idea, and if Harvey did that than his cleverness has gone way down in my expectations.

An M45 geared up but without overspeeding too bad at the redline would just about work, but an M62 would work far better.

Even if it did fit itd be a horribly conplex pipe run tho if you plan to run it before the intercooler.
Certainly dont fit on an S13 without using it as part of the inlet manifold as i tried, and then would need some serious water injection to take care of the temps.
