I'm not sure if this newb-ish question should be in performance or maintenance, so mods please move if necessary .
Here's the story:
My '90 760's turbo needs to be replaced. It's got a good bit of in/out slop and I'm going to swap one of two possible turbos into it.
Option A: Replace the tired 13c with another 13c that's on the shelf that is practically new.
Option B: Replace the tired 13c with a .42/.48 Garrett T3 that came out of an '88 760. This one is practically new as well. I have all of the CBV stuff from the T3 and the rest of the plumbing that would be needed.
I realize that the T3 will require a different oil drain(which I have), and for the oil feed I would make up a -4 AN line.
Questions: Will the T3 oil drain line work with the 90+ exhaust manifold? I assume that both old and new style manifolds place the turbo in roughly the same position, but I'm not certain. I realize that studs will have to be added that are long enough for the T3 to bolt up to the '90+ manifold.
I figured I would do some light opening/porting of the '90+ manifold no matter which turbo I use.
I was also thinking about swapping out the cam for an A cam that I have.
Will LH2.4 get along with the A cam/T3 combo?
I know a 15G would probably be a better turbo to swap in there, but that's not an option as I don't have one; I'm going to use one of the above turbos.
Opinions or experience with this type of swap?
Thanks!
