In short the answer is no, the APS tall boy plenum does not have provision for the aux injectors. Only the APS plenums sold as part of the APS big fuel system will have the 6 cast injector bosses and the additional machining for the aux fuel injectors. This big fuel system plenum is a different plenum casting to the stock APS tall boy plenum in order to save the unnecessary machining cost associated with mounting the 6 aux fuel injectors.




I will have full tech details on the APS big fuel system in the very near future - I will post these details as soon as I have final information from enginering.

I can say that the APS big fuel system is a very comprehensive and designed to be a serious fuel system for high HP VQ engines, APS tall boy plenum with 6 aux injectors, twin high volume fuel pumps, fuel swirl pot, 4 billet aluminium fuel rails with fuel return, etc,etc.

Thanks
