  1. Hey guys, I'm back with another tutorial that I made (thanks to isolation). This is on a how to swap the RB25 bottom end to a RB30 bottom end with a 25 head in a R34 (R33s and R32 should be kinda similar i think) that I did last year. I had to split the tutorial into 3 parts (each part is like 15mins). It starts with preping the RB30 block, to taking out the RB25, and then putting in the RB30/25 and starting it. The reason why I did an RB30 swap was not because of an upgrade but because my RB25 was showing up bad results on the comp tests and there were cheap RB30s going around (I actually made money out of selling parts from the RB30 that I didn't need lol). The goal for this car is only to be a daily responsive streeter on pump fuel (won't ever take it to the track). It's my first time ever doing something like this (I had no help, did this on my own), so take it as a guide line. If I were to do this again, I would definitely use a proper engine crane and take the whole engine out including the gearbox next time, but yeah... this was a real poor mans job and it got the job done and I've been driving this RB30/25DET Neo everyday to and from work as my daily and I've never had a problem with it (have been clocking 5000+ Kms on it as of 10/4/2020). Here's the videos: Part 1: Part 2: Part 3: I'm really happy with the outcome. Considering I knew nothing about RBs or any engine before I bought this R34. I learnt everything from researching (a shit load) on these forums, so thanks SAU, here's me giving back. The car ended up making 323.8 HP on the dyno with my OP6 highflow turbo which is a bit too small for this engine. So I will go with a bigger one in the near future. List of mods on my car previously that I brought over to the RB30 swap: HyperGear G2 RB25DET OP6 highflow turbo with ballbearing 3" turbo back exhaust 100mm thick FMIC Splitfire coil packs Xspurt 525cc injectors HDI EBC Nistune ECU Z32 AFM Walbro 255lph fuel pump (hard wire mod) 98RON Exedy HD clutch External oil cooler Koyorad all aluminum radiator Just something to add here on the side if anyone was interested (kinda like a build page, but I might as well put it here). This was my whole budget explained: So the total amount that I spent on this build/recon/swap was $3415. I bought a complete RB30 engine (without the box) for $150. Apparently this engine was used in a TAFE course for mechanic students to practise timing stuff on, so the pisons had heaps of screw driver marks on. A recon was in the picture anyways because I want this engine to last for ages. So I only wanted to keep the block, crank and rods. I sold everything els (head, alternator, ecu ect) for $240. That's already a profit of $90 lol! The reconditioning of the RB30 block and RB25 head was the most expensive out of the whole budget costing $1420. The recon from Harris Engines in Perth: $400 - Bore and torque plate hone $190 - Face block $180 - Machine and fit crank collar $90 - Acid bath $90 - Face/deck RB25 head $50 - Acid bath head $90 - Face flywheel $150 - Fitment of pistons to rods $180 - Balance rotating assembly All other things: $270 - 1mm oversized Hypatec RB30ET set of pistons + Hastings Rings $253.45 - RB25 ARP Head stud kit (202-4301) from wolf racing $261.25 - RB25DET Neo genuine nissan gasket kit $106.49 - RB30 ACL race main STD bearing set $88 - RB30 ACL race conrod STD bearing set $30 - RB30 small end rod bushes/bearing set $99 - RB crank collar from Lewis Engines $38.75 - RB oil restrictors (one 1.5mm and one blank one) $38 - RB30 brass welsh plugs $13.71 - RB spigot bush $38.98 - RB genuine nissan timing belt fastner kit $41.5 - genuine nissan thermostat $78.14 - Genuine nissan R34 pull type thrust bearing $110.5 - Genuine nissan RB25 exhaust manifold fastner kit $43.2 - Dayco 94407 (T866) timing belt $72.11 - Mamba RB30/25 turbo water braided line kit $81.59 - Braided -4AN hose + fittings for the external VTC feed from Enzed $330 - Dyno tuned car by C-Red in Perth All of the labour except for the recon and tuning was done by me.

  2. Hi guys my names Dan, i have had my eye on my friends dad’s datsun 260z 2+2 for about 10 years now and due to some health circumstances he has decided to sell it to me. Its a late 1974 model with l26 and manual box. Currently red but factory green i beleive. Right hand drive too! my plan is to take l26 and box out and install rb25det engine and 5 speed box. Ive owned many skylines and jdm imports but never a Z so would like to combine the look with the power from new heart! im an auto electrician by trade and have been for 10 years now. If you have any electrical questions im more than happy to receive pm’s through the forum and ill also try my best to help out with posts asking for help! good to be here and im sure there will be many questions but from ive seen so far there is an exstensive amount of info here !

  3. Here are some pics of when we bought the car. I was reading through the service history and it only has 66,000kms. we also found an rb25det With gearbox, ecu and loom Out of an r33 skyline for a good price! I got to see it running the car beforehand and apparently only has 117,000kms but you never know with import cars! Compression test came up quite well sitting at approx 150psi across all 6 (dry)

  4. Hello all. I've been a GTR owner for 1 year and I'm proud to be a part of the SAU community after only being an observer. I'm originally from the US but have been living in Japan for the past few years. Purchasing a GTR has been a goal of mine while living here since sourcing hard-to-find parts locally and from Australia is relatively easy compared to the US from my experience. I've always favored the R33 styling over the other generations and I'm fortunate to have found a Series 3 with very little rust. My main goal is restoration/modernization instead of power upgrades while I continuing to learn the car and it's characteristics. I'm just fortunate enough to know that there are literally decades worth of discussions and data to sift through to expand my knowledge about this fantastic machine. I look forward to chatting with you all!

  8. Nah I only dropped off the vehicle to him to get a base map put onto the ECU for me to be able to start up the car and tow it in for paint. He was extremely busy as we had our Chrome Expression car event coming up. So he only had the car for about half a day before I towed it back home. Thank you for spotting out the mistake though hopefully it hasn't caused any major issues

  9. In preparation for moving house (it's currently running, I don't want to jeopardise that right now!) I've switched my attention to some interior work and it's actually pretty therapeutic and calming haha. I finally have a working AC control unit! I still don't have AC as the condenser was removed from the engine bay and the lines cut at the firewall before I took possession but I'm not fussed, just having a blowing fan is a HUUUGE improvement on warm days. The next thing I picked up free from a mate - a Joying android 10" tablet head unit. Everything works but the touchscreen itself doesn't respond. I took the whole thing apart and I could buy a generic replacement digitiser off ebay for ~$50ish but I'm not committed to the idea just yet. For now I'm using a mouse plugged in via USB. I haven't actually driven the car yet so I'm not sure how annoying it will be, but it's not a daily so not fussed. Then while I had the centre console out to replace the stereo and install the AC unit I stickerbombed all the parts I could (audible groan...). Yeah yeah, it's ricey... ah well... I wanted this to be removable down the track if I didn't like it so spraying clear coat was out of the question. I used a combination of glue dots and super glue (only to stick to other stickers which were already stuck onto the trim parts, not to the trim itself) and it seems to be holding well for the timebeing. Looking pretty good - The final result with everything in place and buttoned up - I get that it's a bit ricey and dumb but it actually looks way better in person than I was expecting it to, especially contrasted against the new-ish black leather interior. Plus that 90s japanese "fast and furious" vibe (stickers, neons, big subs etc) is kind of a guilty pleasure of mine and seems fitting with the stagea hahaha.

  10. Your issue is not the oil drain, it's the fact that you basically sealed up your engine. I'm blown away you have not been sending dip sticks to the moon every time you start your car lol. Do not start the car back up like that. If you want to keep your hoses setup the same way, replace your sealed air/oil seperator with a vented catch can (The ones with a filter on top). I prefer running an oem type setup with 2x sealed air/oil seperators.

  11. There are 3 black plugs in the back of your pnp adaptor the smallest plug (16 pin) is full of spare inputs and outputs. Use your supplied instructions to find the correct input and hook it into that

  12. If you put a pressure sensor on the rail it is interesting. Higher than desired base pressure that then drops back to where you want it then potentially drops off is the usual result You may be able to set 3 bar with engine offf, but when running and pulling vacuum you differential fuel pressure is higher. Not the biggest deal but not great, and makes tuning for big injectors more of a pain.

  15. The water lines don't matter. The turbo wouldn't die even if they weren't connected. Have you confirmed how much oil is flowing through the turbo? By taking off oil return and allowing it to flow into a bucket, you will likely find it is hardly getting oil

  16. Tig skills getting better. Might clean up the welds tomorrow with some polish. Went back to a standard cup instead of the fancy gas lens, not skilled enough for them yet.

  21. I have just completed this conversion and have updated the Excel document. I found an error on it and also added a few missing pin outs.GTR_Guage_Cluster_Conversion3.xls I can confirm everything works on my car, it is a GTT manual. The centre plug at the back of the cluster is different between GTT and GTR. The GTT is a brown 24 pin plug and does not plug into the white GTR 24 pin socket, I modified mine to fit using a hacksaw blade and needle file. I also swapped the lense over to the GTR cluster for the Slip and TCS off lights.

  22. Everything is interconnected. Gratitude for things in life improves sleep. Sleep reduces pain. Reduced pain improves your mood. Improved mood reduces anxiety, which improves focus and planning. Focus and planning help with decision making. Decision making further reduces anxiety and improves enjoyment. Enjoyment gives you more to be grateful for, which keeps that loop of the upward spiral going. Men (and really, all people) beginning to talk openly about depression, anxiety, and realising it affects everyone in not-so-obvious ways is one of the best trends going around too. Probably beats out the fact that Women looking good is now a fitness question, instead of a 90's rail thin Kate Moss thing, which happened along the way too. The biggest takeaway I have found through my own ups and downs is - You don't know you're depressed. You just see the world through a lens that twists what you see, hear and feel. Even happy, stable people should talk about their mental state and get a checkup. Think of it like servicing a well running car.
