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

    • I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

    • Yes, but, I paid cash and I'm pretty sure the receipt was in the bin 10 minutes after I got home Note to self, keep all receipts

    • So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
