hey all, just wanted to ask any guys with 31's whats involved with putting a 20 or 25 into a 31? looking at a cheap 2l pintara wagon and rough cost for putting in a 20 or 25 with auto box.

rather put in this section for a quick reply. wondering if it could be done for around the 4K mark not including the car.

cheers

While I never swapped an engine in my old r31, I did have the misfortune to have the torque converter die... was cheaper to get it converted to manual, so naturally I did that. I think the parts were around $650 which came with the pedals and xfercase and clutch, and around $650 labor to fit.. this was back in 2003 so I don't know if the parts/labor would be cheaper/more expensive but I'm guessing if you got the engine + box you'd save a bit. That said the sr20 is probably cheaper and lighter and they give a decent amount of power and are pretty darn strong... also you'd have to factor in getting bigger brakes and getting it engineered. Dark.Sky put a rb25det into his 32 which originally had the rb20det and he had to do the above so you can guess that there is probably a little bit more involved for you...

gonna struggle doin that on a pintara matt

even tho the r31 platform is different, the trans tunnel on the manual is narrower

*edit* - read that you're goin to do it with an auto, thats not so bad

if its pintara, you'll just need skyline crossmember and some RB30 engine mounts (as the RB20 / RB25 ones push it too far forward and fan chews out the back of the radiator)

if you can find a skyline to put it into, piece of cake. swap RB30 engine mounts off and onto the new motor, run loom, think theres like 5 wires to get it to basically power up (theres a wiki section on R31SC with this info from memory). If you score an S3, the auto is the same as 20DET and 25DET auto boxes (4sp electronic auto)

yeah more than i have to spend though:( only have a budget of 5K at this stage

If 5k total is your budget, I'd definately follow the above advice and just buy a 31 with all the bits and pieces (one with an rb30 will do) - Can probably get a Silhouette for that money in decent nick - good cars

... or just get an R31 Wagon... the GXE's are pretty darn good as a platform to start with... I don't argue with your choice but the r31 platform is robust and is good for many applications - just need to be patient and get the right one

Good luck! I reckon for $5k you'll get an excellent skyline

      I like it when the counter chick leads you out the back into the racks and says "have a grub around in here and see if you can find what you need. I'll be back in a few minutes. Just left me in front of a massive motorised shelving system and 2-3 million fasteners, so I could find a peculiar SS shoulder bolt with cap head. Gotta love country towns.

      I used this https://osgiken.com.au/product/os-giken-os-250r-lsd-gear-oil-80w250-1-litre/   shut my nismo 1.5 pro up by heaps…. Not silent though. Gives the car character and personality. It ain’t a carolla. If you want silent, put a quaife in it.

      It's about the same time for me from Bunnings, or the Fasteners. My big push away from takeaway food, and gluten in general keeps me away from the Bunnings Snags too! Weather up here, I've been out for two walks today in the beautiful sunshine. Had a few little drizzles, and some wind, that honestly, a tin of beans and I could compete on how harsh she blows Thankfully, being this bit inland, we're not getting anything much really. Will probably pick up a bit more when/if Cyclone Alfie decides to come ashore. A few areas in the GC though, and south into NSW are really getting smashed though! Right now, I'm just annoyed Alfie hasn't hit, as I'm not allowed to crack into the BBQ foods like the bacon and eggs until the Cyclone hits "In case we lose power"...

      I love fastener joints, the price difference between them and joints like Bunnings or Super Cheap is amazing, and they either have exactly what you want, or they can get it to quick They have even given me some for free when I only needed a couple of specific size In saying this, I have paid premium for fasteners from Bunnings if they have the sizes I need, but only for convenience really, as my local is only 10 minutes away, the Sushi joint near them is also a consideration  How's the weather Matt? Stay safe mate

      Wideband is worth setting up if only for tuning purposes. I would not mess with the ignition system unless there's a misfire. HKS crank trigger is popular out here for the relatively easily sourced Denso crank sensor, not a bad idea to install as well regardless of power level on a standalone. Boost leak test is worth thinking about. Oil pressure sensor tied to a fuel cut isn't a bad idea either. Getting the tune figured out is a good idea. Without putting eyes on it and getting under it there's no way for us to tell you exactly what it needs but most likely you're down to the last 10% that will make a big, big difference in how happy you are with the car.
