Im new to 4bt swaps and was hoping to find some information on turboing a f6l 912. Im mostly looking to see if i can get away with the stock injection pump or if i can add an aneroid valve or boost compensator to the stock pump. Thanks in advance

Deutz makes both turbo and non turbo engines. If memory serves me right, they don't generally run very high boost pressure. Their compression ratio is17:1 on non turbo engines and 15.5:1 on the turbo models. It could be their piston rings are not designed for a turbo. Don't know if Deutz turbo engines use different pistons in turbo models. The Cummins engines do and you can't turbo a regular engine without changing those. I believe their turbo model is the BF6L912 and there is also a BF6L913T. Here's a shop manual for those engines you might find useful. https://www.deutz-passion.fr/docs/MANUELS_ATELIER/MOTEURS BFL911 912 912W 913 913C.pdf They do have an optional intercooler for these which makes the engine a bit longer since it is mounted out back. You ask about the aneroid. Here's a few photos of one and it definitely has the aneroid. I believe all these use the Bosch A injection pump.
