im wondering if anyone on hear is running an rb25 box in their cefiro and what they have used in the way of engine mounts??

i heard that a s13 ca18 gearbox crossmember can be used and makes it fit perfectly??

Dunno about the Ceffie man, but it's what I did for the R32.

When you drop an RB20 manual box into an auto body, the crossmember holes are too far forward to use the rb25 manual crossmember.

The rb25 manual box will line up with the crossmember holes because the manual box is longer than the RB20 box and the same length as the RB20 auto box.

When fitting an RB20 manual box you need to use an S13 AUTO crossmember because they are a mirror image of the manual crossmember and will allow the holes to line up.

So in your case with the Ceffie, I cannot be sure as to which one you'll need. But if you run into the problem with one not lining up, the other should work.

Sorry man, I can't give you a definate answer, just another option in case you get stuck.

I thought it was when you dropped a 25 box into an AUTO 32, the Xmember bolts lined up perfectly but when dropping a 25 box into a MANUAL 32, you had to modify the Xmember as the holes in the chassis sit about 50mm too far forward.

I used some 25x5 flatbar welded to the 25 gearbox Xmember to suit the holes in the chassis.

Yo bro, that's what I said in the first sentence which refers to the use of an auto body. "When you drop an RB20 manual box into an auto body, the crossmember holes are too far forward to use the rb25 manual crossmember."

The second sentence, still with the auto body in mind - "The rb25 manual box will line up with the crossmember holes because the manual box is longer than the RB20 box and the same length as the RB20 auto box.

Just some wires crossed in communication.

    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
