BACHRISSO 0 Posted July 29, 2020 Hi guys, I’m wanting to put NA FG motor in my BA TRAYBACK. It’s NA BA Auto, can I keep the existing BA auto trans cause it’s held up well? I was wanting to ask, so all the info is in one spot for me. Want to create a ‘to do’ list for myself. Thinks I need to do and change. Someone previously mentioned wiring is different so how do I fix that and someone also mentioned ba sump needs to go on the fg motor, is this a straight swap, bolt holes line up? What else needs mentioning? Ps thank u so much in advance I’m excited as Share this post Link to post Share on other sites
Mr Polson 10,214 Posted July 30, 2020 Simply should bolt on but your dipstick will be in the wrong spot and FG motors don't have a spot to have BA dipstick drilled.Oil pickup will also be different.Wiring and PCM will be different, there's quite a few differences between BA and FG, such as locked dual variable cam vs independent variable cam. FG PCM will be designed to run a 5 or 6 speed auto not 4 speed. Not sure how you'll get around that. 1 gerg reacted to this Share this post Link to post Share on other sites
