Hey Guys, Decided i would make a build thread of my RB30 260z 2+2. Im a 20 year old apprentice electrician and linesman, my first car was a Mazda mx5 and it is to still to date the best handling car i have ever driven. I have always wanted a Z car but the price tag was the only thing in my way of owning one, anyways i put up an add on gumtree one afternoon and around a week later i got a message from a guy on the south coast saying he had one. A few more messages later and we were on our way down from the Blue Mountains to a small town called Moruya with a car trailer. As usual there was a bit of rust in the car and interior looking like it had animals living in it but overall it was pretty clean and straight. $2,750 and 9 hours later i had my first Z First thing i started doing when i got it home was stripping out the interior and repairing the rust to get it blue slipped. While my repairs may not of looked 10/10 i thought they were pretty good for someone with no experience in panelbeating. Areas of rust that i fixed included inside the rear hatch, bottom dog legs on both side and the top of the front right quarter panel. While the paint looks pretty good, it has some bubbles coming through. At this point i decided that because i don’t have much money (being and apprentice and saving up for a house) i would just stick with the ratty theme of the car and embrace it. Hence the plates RAT50N. At last in Feb 2016 i got it blueslipped and on the road. As my brother is an apprentice mechanic and his bosses are kind enough to let us use the workshop we have access to hoists and other useful equipment Mechanically to get it sorted for a blue slip we replaced the front wheel bearings, a new lightweight flywheel, heavy duty clutch (had issues with getting this to work) new slave cylinder and tuned the carbies. (need help! this uploader is pretty stupid and won't allow me to upload any photos)

Hey Everyone, I know this a Datsun forum, but if anyone has an old 300zx they looking to part with I'm possibly interested. I'm looking for in particular a manual, turbo version with a digital dash. Oh, and it's gotta be red - red goes faster . Located in Melbourne, but will travel and road trip it home if home if she's worthy.

Hey all It's been a while since I've posted, but I'm moving out of my current house, and clearing out some stuff I no longer need. Here we have the complete L28 turbo engine and powertrain that I had in my '73 240Z before I put the RB25T in it. I am offering the complete setup here before I decide to part it out! There is the engine itself, which is around 400hp, with a T3/T4 turbo I built up when I was at Nissan Motor Sport in the 90's. The bottom end is an L28 N42 block, with 86.5mm RB30 pistons swinging on L24 rods, and an L28 crank. Cylinder head is a ported N42 with an A-grind cam from a 240Z. The block deck is fitted with 0.060" stainless steel O-rings that ensure no blown head gaskets due to inadequate gasket clamping. The inlet manifold is a customised 280ZX fuel injection manifold with a larger VS Commodore throttle body. Fuel injectors are from a Supercharged VS V6 Commodore engine. The exhaust manifold I made myself and is constructed of heavy wall steam pipe for very long life. It has a custom oil pan that I made along the lines we used to run on the HR31 Skylines at Nissan Motor Sport, complete with trap doors and 7 litre volume for high performance use. It has a lightened flywheel and R32 Skyline GTR clutch. It has crank triggered ignition along with a Motec M48 engine management system, fully calibrated for this package (that's $1,000+ worth of tuning right there!). The engine has probably done around 10,000km in it's life due to the occasional driving I use the car for, and has never been raced. It has had 50/50 coolant in it the whole time, so there is no corrosion in the aluminium components. The gearbox is one I imported from Canada from a 280Z. The FS5W71B transmission as fitted to non-turbo cars that North America got was different to Australia, and had more favorable ratios for a turbo engine, including 5th gear (0.745:1 compared with 0.864 for Australia). With a 3.7:1 rear axle this engine is at 2,500RPM when cruising at 100km/h. I changed all the bearings and seals in it when I put it in the car, and it's in excellent condition for a gearbox of this age...it has not done much work and makes no bearing or gear noises when driving. The car was calibrated at Amberley Autos and starts right up as well as making blistering torque and power from around 2,500RPM. The engine makes useable boost from around 2,000RPM. Even with 235/40R17 tyres, my car will break traction in 1st, 2nd and 3rd gears.....it's a very capable package. All inlet ducting, custom made 3" mandrel exhaust system, sensors, fuel pressure regulator, boost control, wiring harness, ECU, radiator is offered. The only things required to support the engine installation into your car is an intercooler, electric fuel pump(s) and electric cooling fans should you choose to run them.....I even set the throttle up so it interfaces with the standard Z linkage setup for easy installation. The engine was removed from the car in 2010, and I would suggest a once-over including replacement of a few seals and gaskets may be in order. I have these parts, and can do it for you if needs be, or you can do it yourself if you'd prefer. Otherwise the engine was preserved when I removed it and will start right up with a minimum of effort. You will get a powertrain that turns a 240/260/280Z into a rocket ship, and all the hard work is done to fabricate things and get the whole lot working as a package, including the tuning which is no small thing with custom turbo charged engines. The whole lot is yours for $5,000, which is a fraction of what it took to set this powertrain up. Cheers! Jamo 0425 786 388

Hey guys, I have been trying to sort out my parts for my build and as I have collected a lot of stuff over the years I am having some trouble identifying a couple of things. Firstly is this turbo manifold. It was with my L28 when I purchased it (not on the engine) and I did a rough mock up to see if it would fit today but seems to be a few mm short on the end lugs (I am pretty sure middle ones line up just either end) and I did notice a lot of the US manifolds are actually sliced right through the last holes on either side giving side to side movement where as this is just a hole for the stud. When I purchased my engine it was a bunch of parts already torn down and such and a lot of spares as well. Secondly is this cam. Now I have seen in USA that turbo cams in the p90 are similar with holes drilled throughout the cam with no spray bar but there is a spray bar attached to this one as well. It was also located in a box with all my engine parts. Basically also need to know if its safe to run without the spray bar. Basically I will be updating my sale post with a few more items for todays clean up but need to know if I can make this turbo manifold and cam work for my L28 turbo build (P90/F54). Thank you for any help you can provide.

Hey guys, I'm putting my old project car up for sale: http://www.ozdat.com/forum/viewtopic.php?f=66&t=6303 to be honest I'm unclear what I should be asking for the car, but it's a fun car, and when going, it's fast as hell. I'm looking for around $15,000 13,000 for it. It ran a best of 12.83 @ 115MPH on 9psi with a 2.2 60' time (195 street tyres and an open diff). It's currently tuned for 19psi and has a locked diff, so is obviously substantially faster than that.

Custom simple alu panel with a couple of Autometer gauges. The bad bits: The engine definitely needs a freshen up, and a proper L28ET oil pump. First outing around calder park (see link at the end) when the oil cooler first opened it, coupled with a standard L20B oil pump (previous owner installed) lowered the oil level sufficiently that with semi-slicks I lost oil pressure around turn 1 and ate the bearings. It needs new main bearings, and likely big-end bearings and a general refresh too. The body is not rust-free. Honestly it needs some tender love and care on the body. I don't know the exact condition until I get to the car in November. Thanks for looking, if anyone has read this far, I also have a few other parts I'll be putting up for sale, 2 4.4:1 R200 LSDs, 1 with the axles and CVs still (sale pending), a mint 1600 primered shell (6K in body receipts from bodyz by nick in Ballarat), a 5000Km old S15 SR20DET and 6-speed, 1600 adjustable rear x-member from datsport, and a few other things that I can't remember right now Dave https://www.youtube.com/watch?v=0BFqmn7IelI
