Testing every engine swap for the P64 (Porsche 964) in CarX Street Class 6 to find the fastest build and best setup.
Today we’re pushing the Porsche 964 to its limits in CarX Street by testing every engine swap available for Class 6. From turbo-4 builds to turbo-6 monsters to the stock boxer setup, I ran full performance comparisons to see which engine actually wins.
Some builds looked strong on paper… but one swap completely broke the competition.
If you’re building a 964 and want the fastest setup possible, this is the test you need to see.
