It's a bit confusing for sure. The 2L's have overheating/head cracking issues, the 3L head swaps on and resolves this problem. It's still going to be a bit underpowered for this application, but would be great for offroading. Just not great for highway speed passing.
I have used and still own a 2.8 L DIESEL hilux SSRX (Not in USA). Works find, but my friends who has 2.4 L turbo says not enough power when you have AC on.
Also in the advertisement, the AC compressor is missing.
