Engine Cover - Why Not?

[morsk]

I was watching an older Car Care Nut video on our T24A-FTS engine, and he mentions that the engine cover for the T24A-FTS engine in other Toyota/Lexus models serves as an air channel to cool the turbo in the back (03:04 - 04:10 timestamp).

I thought this was an interesting design and was curious as to why Toyota decided not to give us engine covers on the 4Runners. Thoughts?

Just a guess but my thought would be that our engine sits longitudinal instead of transverse so the airflow required is different.

Exactly. Beyond orientation, the cooling systems are different. I think the longitudinal and transverse versions only share like 60% of parts or something.

Thanks! Makes a lot of sense. Something I didn't think about...

A tangential question, if you know the answer: The label/sticker on my engine reads: "T24A-G21." Is the "G21" in reference to the transverse version of the T24A-FTS family? Always wondered what this actually indicated.
