At this point in my build I'm looking at a motor. My E-AB can take up to an IO-540 so structurally by weight budget is 438lbs (O-540 dry weight).
The LFX is 300hp, and GM lists the 'engine plant as shipped weight' of 345lbs. My guess this is with accessories like alternator/AC/emissions that could be removed.
Since almost all the engine stuff I can find online seems to be for older motors or V8s I wanted to start a conversation about the possibility and pitfalls of using a new, all aluminum, V6 high performance motor.
Heres some dyno info: https://gmpowertrain.com/2014_images/charts_lg/lfx_chart_equinox.jpg
Two things come to mind. Fist, a standalone ECU/ECM. I have read that there are standalone ECUs that WOULD support VVT.
Since this is a dual cam VVT motor would that be a reliability issue? My thoughts: NO. At a reasonable TBO you can rebuild before and long term issues crop up.
Stand alone ECU: Lock out VVT? Keep it? I would assume that VVT plays a big part in the performance of the motor. Would/does locking out VVT make a 300hp motor an 150hp one? Or would you have to dyno it as see??
Please keep posts on topic (yeah.. good luck with that lol).
