I don't know if I'd argue with Markku - note his location!! And he's correct, the 606 pump is still largely mechanical. I assume they've deleted the electronic controls, which if similar to the 603, are a luxury - not a necessity. How the heck did they retain air conditioning though? There's no room for the giant intercooler, condenser, radiator, and electric fan...! The 722.3 auto tranny (in the 124 with a 603) was also used in the 500E, E60 AMG, SL600, etc and can take the power if beefed up accordingly.

What I'd like to know is what kind of power gain I can get out of a 603.960 with the STOCK turbo, pump and injectors... just by adding an intercooler and tweaking the full-load fuel delivery, WITHOUT sacrificing fuel economy. I know at least 20% gain is feasible with no major mods, but I don't know how MPG suffers, or how much more gain can be had. Hmmm.


michakaveli - you can't bolt on a turbo to your non-turbo engine. The turbo engines have oil cooled pistons and stronger internals to take the power. Slapping a turbo on would very likely destroy the bottom end in short order, or if not, it would drastically reduce the lifespan of the engine. Much better to swap the whole engine to a 606.96x, or just trade up to a 98/99 model that came stock with the turbo (and then slap a chip in the sucker! )
