I can barely understand your broken english but you can use a manual diff with upgraded gears in an automatic. You will need to get the differential from a manual car I think they are $400-$600 used. I don't know what you want it for but 3.3 to 4.36 is a massive jump.

But consulting a simple gearing chart would be far too logical and practical where holeshots are the desired effect. 🤡

Sure, if you want to redline at like 80mph... What is your goal here, with this car?

its just a stock na, just want the car quicker and I heard that the 4.36 gears are amazing with na and alot of fun.

To be nice I put the numbers in a calculator because I was interested. Be aware this will absolutely destroy any usability on the highway. It would be recommended to only upgrade to the manuals stock 3.5 or slightly upgraded 3.7 gears. Past that you can/will depending on the year and your tires create usability problems like disabling the cruise control.

Stock with 3.36 - 67mph 2400 rpm, 72mph 2600 rpm, 80mph 2900 rpm

with 3.7 - 68mph 2700rpm, 73mph 2900rpm, 81mph 3200rpm

4.36 - 68mph 3200rpm, 73mph 3400rpm, 81mph 3800rpm

4.36 gears would make it worse than driving in 4th on the highway with the stock gears. Pretty sure a 3.7 rear end already has a dramatic effect on MPG and with a 4.36 you are probably pushing under 20mpg on the highway.

^This.... Gotcha'. Is this your daily driver? If it is, I wouldn't go any lower than 3.7. '03 & '04 models had issues with cruise control on 3.7 and lower gears, but on '05 - '09 you should be good.
