❓ FAQs:

Q: Will this fit the older 4JJ1 MU-X?

A: Not as a direct fit. The 4JJ3 turbo is a popular upgrade for the 4JJ1, but it needs custom piping, a conversion bracket to adapt the 4JJ1’s vacuum wastegate actuator to the IHI electronic actuator housing, and a tune.

Q: Does it come with gaskets?

A: No. The gasket set is sold separately.

Q: Is this the same turbo as the D-Max 4JJ3?

A: Yes. The 2021+ D-Max and MU-X share the 4JJ3 and this IHI turbo.
