when I said 200hp, that was crank HP and it is the limit of what the IP can supply. 140hp is a realistic number that most anyone would get without a myna IP and a few K$ in internal and external modifications.

With the money it takes to get over the IP's inherent limits, swapping an OM606 would be far cheaper in the long run.

Even if you get that 140hp, any STOCK W124 300D could still walk all over it.
