hey guys, it appears my bottom end is gone to crappers.

im wondering will a rb 30 bottom end bolt straight on...or the 25 head bolt straight on for that matter..

Do i need to use a vl turbo engine for the conversion since my rb25 is turbo? or will any rb30 bottom end be suitable? also

will my rb25det (automatic) gearbox bolt onto the rb30?

dunno if these questions are dumb or not. any info would be great thanks :no:

ok i might just clean that up a bit,

i currently own a Nissan R33 Skyline

Rb25det (automatic)

Bottom end is crapping itself

Im wondering what i would need to do in order to use a Rb30 block, If its even possible.. Sorry for any confusion

Would engine mounts be fine? Would gearbox match up? Would i be able to use the N/A rb30 block?

Is there any benefit at All in doing the 30/25 combined engine powerwise? or am i stupid :| :no:

Its all do-able.

Lots of info on the R31 club forums about putting twin cam heads on rb30 blocks, and using rb25 boxes.

    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
    • I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option 
    • You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)
    • I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.
    • Heh. I copied the link to the video direct, instead of the thread I mentioned. But the video is the main value content anyway. Otherwise, yes, in Europe, surely you'd be expected to buy local. Being whichever flavour of Michelin, Continental or Pirelli suits your usage model.
