What's the difference between a twin turbo and biturbo (i.e. 600 vs. 65)
Hey everyone,
I know this is kind of a silly question but I wanted to know for my information what the difference is between a twin turbo that's in 2003 and up CL 600s versus the biturbos found in CL 65s and for that matter all 65s? Thanks in advance.

The engine is bigger because it's bored and has a stroker crank. The turbos have more boost, but the pistons are forged and the fuel injection system is calibrated for increased flow.
I doubt that just bolting the 65 turbos on a 600 engine would be a useful exercise.

They are two different terminologies for what type of turbo configuration you have in your car. Example: Mercedes bi-turbo, or the Audi S4 2.7 bi-turbo. What this means is that there is a turbo for each bank of cylinders, and they are located on opposite ends of the motor. However, in a car like the Toyota Supra MKIV, that car is a twin turbo because it is an inline 6 motor, and the turbos are located next to each other. One feeds off the other (there is a smaller turbo that spools up to create less turbo lag, at which point a larger turbo kicks in for the higher boost). From what I understand, that is the "technical terminology"

Do not confuse Biturbo / Sequential Twin Turbo with "Twin Turbo"
Biturbo is the same as "Sequential Twin Turbo"
Basically, you have 1 smaller turbo for lower RPM range, and a larger turbo for higher range. It helps greatly reduce turbo lag due to the smaller turbo can produce boost much earlier than a super single or twin turbo setup can do. At lower RPM, the smaller turbo spools and produces boost - then when you reach a preset RPM or boost level, a staging valve opens and directs air to turbo 2 (large one) and it now produces the boost for the engine. Usually, stage one turbo is turned off, or its boost is sent into the compressor intake of the stage 2 turbo to achieve a higher output pressure.
Do not confuse Biturbo / Sequential Twin Turbo with "Twin Turbo".
Twin turbo is having two EQUAL size turbo's. Each runs off its own cylinder bank in V or H type (boxer) engines, or off of a turbo manifold on inline type engines. Both turbos share the load equally in producing boost air. (Like a dual core processor in your PC - both run at same speed, sharing the load equally) So, turbo lag still effects this type of setup, as both turbos will spool at the same time.
