Hey i'm wanting to put a RB25det NEO into my R31 silhouette and was wondering if there are any major problems with doing this or if the engine would even fit under my bonnet. I was planning to get a R34 half cut and doing a manual conversion as well, was there any major issues in doing this.

If anyone has done this before some info would be great:)

conversion is pretty easy ive done it to my s3 wagon, umm cant think of any major obstacles i came across, you need to use the rb30 engine mounts and mounting brackets, and you'll also need to make up your own gearbox cross member mount... nothing different from an rb25 engine swap im pretty sure... the gear stick comes up in pretty much the right position and the engine sits nicely in the engine bay, nothing sits too high and there is plenty of room in front of the engine if you wish to go with twin thermos... it doesn't look out of place in any respect

dont go thermos, keep the stocker clutch fan and shroud, much better and all fits nicely if you use 31 mounts. also going from your profile yours is a s3 auto, in which case your stock auto gbox xmember will bolt up the 25 box no worries. will need a 33/vlt yoke on a manual tailshaft or a custom single piece

      Yes, I know🙄 but the sequential is not in my budget... don't want to reduce power neither, so looks like I'm stuck in the rabbit hole🤣

      You’ll be very upset when you bust that too not to mention the gearing totally sucks. Don’t do it.

      Is the panel filter one that is oiled? Have you ever cleaned or touched the AFM?

      So.... the K&N air box thingo was too big, ended up gifting it to a mate, well, by gifting it he actually supplied food and beer at the pub,  which was nice, as it will not sit on a shelf in the garage for the next 10 years I did trim up some of the existing stuff to neaten it all up and gave it some wrinkle paint, unfortunately it currently has a used and abused mish mash of different types of hose clamps, 4 big fat T bolt type (shit), and a few normal clamps of vairing sizes and brands, but..... only until the 6 constant tension black worm clamps that I ordered from EFI solutions turn up next week Currently the current hose clamps are triggering me hard, LOL Is this the final version, probably not, I really want just 2 silicone pieces, a straight bit of silicone from the filter to the MAF is easy and will happen as soon as I head into Just Jap tomorrow, the problematic part is a 30° silicone bend from the MAF to the TB that I can connect the engine breather from the head, I found that there are bulk head fittings for boat bilge pumps that should work, but until I can get a 30° silicone bend the alloy pipe, and the 11ty thousand hose clamps, are there for the foreseeable future 4 hose clamps are golden, 6 are grudgingly acceptable, the 8 currently holding it all together is just taking the piss    I've also ordered 60 more retaining wall blocks for the front yard, I mis-gonculated the height that was required to get above the base of the Photinia's (red robin's) that are the hedge behind the front fence, currently it is 2 blocks high, and about 1/2 a block short, so going 3 blocks high will be above the base of the red robin's, and allow some room for mulch

      It is the stock air box with the panel filter. Everything else is stock except the exhaust at this point, as I also went back to the cleaned 270cc injectors. I will check the RPM when the IACV is unplugged and report back.
