does the r2s turbo , a 2 stage turbo and a twin turbo mean the same ...well my idea of a 2 stage turbo is that where compression of air takes place in 2 stages ..so does it consist of 2 compressors?

There is no standard nomenclature with this.

2 Stage turbocharging is fairly clear - There are two turbos an LP and a HP (in series). There will be some measure of bypass and control.
Twin turbo/biturbo can either mean 2 stages of turbo charging (series), or two seperate single stage turbos (parallel).

Say on a V engine. You could have one large turbo feeding both banks, or Two identical turbos, one to feed each bank.

A good example of twin single stage turbo engines are BMW diesels. These feature a small turbo which prevents turbo lag at low engine RPM, along with a larger turbo for higher RPM

The R2s is basically a "compound turbo" in a single package where typical compound turbo setups run two separate turbochargers.

Saw one on the LeMans audi testing at the shuttle landing facility two weeks ago.
