This is not correct. You are basing this on a parts list that is for a 5-speed:

https://www.evolutionm.net/forums/sh...76#post3648976

Notice in that document that there is no mention of 6th gear? Also notice that the title of the document is "Standard Parts Evolution V" (pre 6-speed)?

As of this time, there is no proof that the Evo IX 6-speed has a different 4th gear set than the Evo VIII 6-speed.

 

Since I wanted a return that went to both the fill and a smaller line that split out and put a spray directly over the 3/4 gear hub and slider, I used a fuel block (like the Aeromotive AEI-15620 from Summit Racing) and it did the trick. You can also drill and tap a hole into the block for a temp sensor, just make sure you ground the sensor or you won't get a reading. This particular setup has been on my Galant VR-4 5-speed for a couple of seasons now with no problems. I went from 250+ temps (maxed the gauge out in 3 laps) to 180F normally up to a max of 210F in extreme situations (high ambient and long runs).

Wish I could run this particular setup on my SCCA Evo.

I answered your other question in another post... Good luck

 

I will be running the same setup, spraying the cooled fluid over 4th gear. I hope I have the same type of temp reduction you did!

 

I pointed that document from the coordsport parts bin to indicate what the part numbers for the 22414 which fireball qouted as saying that there are two part numbers for that piece and one is for the '03-'05 5 speed and the other is for the '06 6 speed. we are past comparing 5speed vs 6 speed at this. we are actually comparing 4th gear pieces. as you know that the evo IX 6 speed is definitely different from the '05 evo VIII MR 6 speed because they changed the ratios and the 4th gear is different.

if you actually care to read the whole thread and a related thread you will know that although the '05 MR and the '06 MR have the same 6 speed, they have different ratios based on their product manual, based on the mitsubishi website and obviously without stating it they are different. the TRE pic of the MR 6 speed is from the VIII MR. so far, I have not seen them show the internals of the '06 MR with the 4th gear damage.

whatever happened to your post#309 about the difference of the 22414? did you get the answer as to why there are two different part numbers for the 22414?

 

I just talked to the mitsu tech that I know of and after checking the part number for the 4th gear piece using my VIN, it is a 22414 alright except that the one they use in the IXMR is a stronger piece with more gear teeth in it vs. the '03-'05. It is so new that they couldn't get an actual part number on it and even had to call the main mitsubishi HQ to find out.

 

thats interesting since i did mention that noone speaks of the 064th gear failures

 

My 07' racing season starts at CMP in Feb, so I'll update this post if/when I have issues. Hopefully changing gear oil after each race and the cooler setup should limit the issues.

 

well this is good news! Hopefully the 06 mr IX 4th gear is interchangable. I will buy one for sure

 

Fireball posted what he thought was 6-speed gearbox detail in post #302. I wasn't paying attention and assumed it was the 6-speed gearbox, but its actually the detail for the 5-speed. The part numbers he listed in post #308 are for 4th gear for the '03-'05 5-speed and '06 5-speed. The detail on the 6-speed gearbox is in post #305.

 

The '05 and '06 6-speeds have the exact same gear ratios. Its pretty hard to change the number of teeth while still maintaining the exact same gear gear ratio.

Something to think about the next time you select track tires...

This is pretty much the selection of Hoosiers available for us T2 guys...

Notice the difference in the RPM/MPH range, if you know the type of track you're going to frequent you might choose the size accordingly. In some cases the difference in tire size choice may also mean the difference in the number of shifts or amount of time spent in particular gears.

Good luck...

 

how so?
why couldnt you just change the pitch of the gears?
I remember doing that all the time with my RC10 rc car...

 

Hard for me to explain, but even when just changing the pitch, its still very difficult to maintain the exact same gear ratio. Its not hard to get close though. Mitsu lists the exact same ratio out to three decimal places for '05 and '06 gears.

 

even if outside diameters are the same?
