Quick and simple...

How many of the restrictors are needed?

That's a giant debate and people have strong opinions either way. The SAU guys swear by them.

There is a chart on SAU that iirc states that your to plug the rear and put the 1.5 in the front. I ran the 1.5 orifice front and back on my rb20 w/ N1 pump and had no issues.
