what c15 do i have??

Never in all my life have I heard or seen a 6nz owner convert to twins lol but hey too each their own if you guys support such a thing.

 

I know that. Just saying that off other comment fella

 

Not 100 percent sure but if it was me, I would clean it up and tie up all the loose ends and get rid of the heat to make the motor last. Single conversion.

 

Oh please........... elaborate, what heat are you talking about here. It's a 6nz with a set twins . It probley runs cooler then a single turbo engine. What exactly are you saying? The EGTs are through the roof now because of all the air the engine is getting ? ....

 

Why don't you look for a serial number on the block? You didn't confirm if you have 1 or 2 plugs on your spacer plate under your valve covers. In the pics , it only looked like 1 but I could be wrong

 

california isnt checking trucks engines like so many people think they do .. my 08 389 has a single turbo SDP and im currently on my 5th straight week running into California from texas. all i run is tx to ca and back to tx. i have never seen carb at any scale and i run up and down 5 from norcal to san diego

 

Look where the cam sensor is located. Bxs had them in same place as 6nz. Bxs uses a 70 pin ecm. But only specific to the bxs. Mother board inside is different. Pull a valve cover and see if it has the add on vva's.
