im pretty sure its not a direct change over....., cause a few things wont line up & the plenum chamber might affect it.

anythings possible if you got the time and money.......you'd have to customise one of few things to suit.

if you look into the search....i think many people have attempted this

Yeah I had a quick browse through search function and I couldn't find anything. .

Plenum is front facing so shouldnt be a problem. . Not sure about the other things??

the brackets i imagine are different...so hence.....the rocker cover etc needs to be modified....

im pretty sure the inlet pipe that runs along the top of the RB25DET will be an issue....

as the RB26DETT does not have the plenum chamber set + inlet set out that way

so hence...modification is necessary.

thats funny....i just typed it in google...and HEAPS showed up.. as i said, this is something that many peopel have tried or want to do

ask 2G U UP (anothony)

I dont think it will be a problem I have an RB30/26 and I had to put 25 covers on because of the 30's deck hight so I think it will bolt on.

[ClutchBurndout-:(]

How come u would want to do that?

[sikjet]

It's not that I wanted to run them I had to because the 26 covers are biger then the 25 covers and they hit the bonnet I'm running the 26 covers now but I had to cut the bonnet.
