hey ive just spun a bearing in my RB20 in my ceffy, and am curios how hard the conversion would be from rb20 to a 25. As i read in another topic i can just bolt the rb20 mounts onto the 25, and i already have a rb25 gearbox running in my ceffy. Has anyone done this conversion and give me a guide as to what else is involved or what do i need to modify/convert, because by looking at the 2 engines it doesnt look like theres that much involved at all?? Any help would be great. Thanks dean.

ok thanks for that il keep it in mind, but im pulling the rb20 out as we speak so once its out and i have my rb25 il sit the 25 in and see where im at because the only thing im worried bout is i wont b able to do myself is match the 25 loom to the ceffy's body loom, and also any random pipes or connectors..?.(i dont have a rb25det yet if anyone has one for sale in sydney)

when i did mine, the powersteering was different, might not be the case for you. i just unbolted the mounts of the rb20 and bolt em to the 25, saves you removing the powersteering and lines etc etc. and using rb25 belt :P works mint. And yea i got my loom done here in nz for 350$ mint ae :P

    • LOL, when one "money pit" is never enough Noice, and excellent work mate
    • I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed
    • I hear that would involve some nice country road drives into the hills for Mark...
    • I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.  
    • Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
