has anyone tried one of these. i asked on the the E30 board but everyone ended up talking about E21 turbos. they were talking about how the EFI turbos were not as efficient as non EFI. if anyone has any leads please let me know. i was wondering if maybe DINAN made one, or some other companys that i could look into. this is a futuristic challange. it is not about the horse power. i want to do the work myself... thanks.
