Hi all well its about time i did this as this is now my second engine 1 every 2 years not to bad for the hiding it gets.

My question is what is really involved in the conversion SO I can get the nessecary parts, diagrams needed so I don't get half way through it and find i need to get a part from Japan ex 3 weeks sort of thing.

The Thread RE: RB25det conversion helped but need to fill in the blanks

The thread for the gearbox is pretty self exlpanitory with the speedo cog thing.

Sorting or getting a one peice (which is what I think i will do) tail shaft is easy to sort.

Will the tunnel or fire wall need to be pusuaded eg with a hammer. to fit the rb25??

How hard is the wiring up of the 25 loom into the 20 loom??

I think their will be more questions as I get started I think

Cheers Billy

hey mate, putting the rb25 in2 a cefiro is sooo easy hey, use rb20 engine mounts on the motor, im pretty sure u dont hav 2 bang nething 2 make it fit, just 1 piece tailshaft, etc, n diff gearbox mounts im pretty sure, we used the rb25 ecu on mine, but modded it in2 the rb20 harness under the dash so everything stayed the same, if u want the guys number who did mine ill try n get it hes in brisbane.

    • Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
    • I also used NP   That’s were it’s seems to be the best place to fit it? All schematic shows also that it’s should be referenced from the turbo housing. But idk, I do see high hp cars without any connection or anything to their turbos, so I really don’t know how they connect their things
    • I do have loctite 243 and 246 and a few more models. I could drill it now in place and make new threads for m12 and order an4 - m12 coupling and fit that to the turbo. Run a braided hose to the EBC which I could get a an4 to 1/8npt 
    • So M12 and sealant should be fine?    NPT ” because that’s what I had and what I could get atm. 
    • Wouldn’t touch par if they gave it to me. You need to ask how much power you’re looking to make and then add about 50% to it because that’s what you’ll end up making  The factory box says no more at about 350kw or so, the upgraded synchro boxes won’t handle much over 500kw for long and at that point you’re looking at an auto or dog engagement manual,  once you’ve gone dog engagement you may as well go sequential, they cost a little bit more but it’s worth it  also while you’re at it you should upgrade the transfer case with 10 friction plates
