Lower my rpm's on my evo 5?

Hi.

im using my evo 5 as a daily. I have a rs rear diff if it matters. In 120 kph my rpm's is at 3500. My friend have a evo 8 5 speed. In the same speed it is right under 3000. Could i get a evo 8 gearbox and lower my rpm's or what would you suggest that i do?

Evo 7 gearbox is a straight swap.
My evo uses the 7 box, great for freeway driving, lower rpm and higher top speed.

MR953341 EVO 7

Final 4.529

1st 2.928
2nd 1.95
3rd 1.407
4th 1.031
5th 0.72

1st and 5th are longer, 2-4th are exactly the same.

The evo 8 gearbox is not a straight swap.
It uses a different type of transfer case and mounts.

I wouldn’t bother mate.
7 box will do what you need, with less labor charges from the garage.��
I saw your thread on the MLR.

Weird, according to antony on indigo gt, the evo 8 gearbox is bolt on with the evo 5 transfer case?

It’s probably just the box mount that’s different then.
The 9 is definitely not compatible. And stay away from 6 speeds
