what is better a regina or bosch system on a volvo?
#3
What Lev said ^^^. Certain Regina specific parts are particularly more expensive. The coil in particular. Some Bosch parts can be substituted, for instance the fuel pressure regulator. Regina uses a 2.5 bar fpr while the Bosch uses a 3.0 bar. I've used a Bosch with no issue. As far as unmodded daily drivers, both are nearly bullet proof systems. The only real issue is for those few people wanting to turbo a Regina car without swapping the entire motor and injection system. There were no turbo Reginas so no ecu's with turbo fuel maps exist. There have been some turbo conversions; I believe those folks went with after market systems such as MSnS for fuel/spark management. Also, I believe there were no manual transmission Reginas.
