B58 Engine Teardown

Recommended Posts

Really interesting tear down of the New B58. 

Quite a few surprises over your normal 6cyl Turbo. Very interesting.

Just saw this and was about to post haha. Anyway very interesting its looks like its quite a strong motor. Cam chain at the back is a potential worry if the tensioners wear.

Yea I came accross this today aswell. I wonder why the cam chains are at the back? It cant be weight distribution I wouldnt think.

Yeah that's interesting. If anyone finds out let us know. Also the block looks good. 2jz boys will be crying when they prove how much better the B58 is over the old donk.

Heh, cam chain at the back worked out real well for Audi.

Issues I saw for aftermarket:

  • Integrated intercooler/manifold.
  • Integrated exhaust manifold.

It's a great piece of packaging design, but I think that may limit potential for serious modification.  It's certainly superior to a JZ motor in almost all areas, but then that's 25+ years of progress for you.

Manifolds both came off though.  Meaning they will make something more traditional to replace them.

I would say the most difficult part will be programming that Vanos stuff.

I enjoyed that, seemingly lots of potential.

I also wondered about the intercooler, that's a serious compromise. Replacing the whole manifold is a solution sure but it'll be a crazy expensive conversion.

I'm not sure that was best practice on cam removal. 😲

Will be interesting to see how they fare with higher hp. You can make some rather fruity hp on a 2JZ with some money spent on ARP bits. But you can make similar HP on an n54 too without doing internal work

I'm not even a fan but have to admit the 2jz is a good engine which has stood the test of time (a long time). I don't think there's any need to make it an us v them situation?

Its a good looking engine with all the plastic removed.

Oil filter looks to be in a prick of a spot?! under/behind the manifold?

In really big HP applications its the 2JZ block that is the weakness bit in mid power 5-600 HP applications its strong. I suspect that B58 block is strong looking at the design  but it is alloy not cast Iron  and that may be the limiting feature. Saw some block testing done by an Aussie engine builder and the Ford Barra block was a s good if not better than the RB and 2jZ blocks.

I was thinking that too.
