Re: Sonoma GT With a SY/TY turbo.
I'm sure you could, but for all the work it would take to get all the right parts in there you are better off to just put a complete SyTy engine in. Think about the routing of turbo oil lines and coolant lines, and drilling the block/pan would be a pain while it's in there, so it would have to come out anyways.
Getting the downpipe to fit the 2wd frame takes some massaging too, easier with everything out.
