Difference between mitsu 4g64 and Hyundai 4gcs?

So going back to rod and ratio and differences of the 2.4L block (again just checking all of my options before I go building),

Using a stock rod will give me a 150mm/100mm= 1.5 which is the same as a 2.3 stroker engine. (the article was great info and I am still spending time on reading it but they probably didn't go over a 2.4L because the 2.3 to 2.4 is kind of close).

There is a longer rod out there that will give a 156mm/100mm which gives a 1.56 rod ratio

But a 162mm/100mm= 1.62 from 1ViciousGSX motor is pretty impressive compaired to the 1.7 in our cars right now. This is unless he is running a 2.1 destroked engine which is what I see most engine builders use these 162mm rods for

i can see how switching to a 156mm won't provide impressive gains but going to a 162mm seems pretty impressive. Is it worth going this route to get the extra rod ratio? I don't know if Vicious ever compared the rod ratio of cars to cars but I was just wondering why he went this route.

I am kind of interested in knowing what goatblower is running in his 2.4L motor also.
Who else is running a 2.4L block? What rods/piston setup are they using?

I have a spare 2.0L block for parts and the 4g64 block. I am hoping to get 2 engine stands and put them side by side to compare differences between the two. Should be kind of interesting. Just need one more spare engine stand

I'm running a 2.4L engine. The 162mm rod is what Magnus was installing in their long rod 2.4L, which sounded good to me. I've got the Ross piston/Pauter rod combo. I take it to 8500rpm a lot of the time, no issues.

The main difference in the 2.0L vs. 2.4L are the lack of oil squirters (my 2.4L does not have them), knock sensor bung not there (although you can use another location on the side of the block), the two (2) small coolant holes are not drilled at the timing belt side of the deck (just drill them) and the 3mm taller deck the 2.4L block has. Other than that, minor differences exist.

Magnus just came out with a 2.2L engine that runs a 94mm crank, "best of both worlds" kind of set-up. With a 162mm rod I'm sure the rod ratio would look really good.

My opinion;
Street/strip car, go 2.3L/2.4L
Strip only car, go 2.0L/2.1L/2.2L
