M103 Mosselman project
 

Im preparing to do a mosselman Twin turbo projekt om my W124 300 CE..

I need some advice;

What exhaust measures would be optimal i plan running about 0,5 bar, could i go with the stock exhaust without problems or loss of power?

combined with the mosselman kit i got turbo technincs steel replacement for the rubber housing under the ke-jet, with 2 additional injectors but no controller? what options do i have here?

Engine specs, 12,5 bar on almost every cylinder, nr.6 12 bar. according to factory specs comression should be at least 13.5 bar
New connector rod bearings installed, the old ones was noisy..
No oil leaks ATM, head was done by previous owner 40.000 km ago.
