Popular Post fletch Posted June 15, 2022 Popular Post Share Posted June 15, 2022 I got this back when i was an apprentice and did many of the period correct mods. RB30DET, cut a hole in the front bumper for larger intercooler, loud exhaust, terrible surge tank in boot, poorly fitted gauges (not in the A pillar to my credit) etc etc. It went terribly fast, and ran kind of poorly due to some lol issues that i never worked out at the time. I went overseas not long after and i kept it in an old barn on dads farm with dreams of someday spending a heap of cash on it and doing skids etc This pic was early 2019 when we dragged it out of the shed. Lack of genuine barn dust due to being well covered for 10 years. Nothing happened until maybe a month ago when i got the motor out and apart. Assume the position like the rest of my shed - bonnet up.. Im not sure about the condition of the crank, it has some marks and has already been ground undersize, so i stripped a spare rb30 and will get it measured up and the machining done in July hopefully. So far, i have nitto rods, CP pistons 8.5:1, link G4X fury, 1000cc injectors, GTX 3582r, sinco manifold Its 4wd so i might buy one of those flash PRP block brace/adapter plates. Apparently they are necessary, as if you have 600+hp and a front LSD you will crack the block. But they are expensive, and so is a front LSD. so i might pass on that. Also bought a bosch DBW throttle, and got a 350z pedal assembly, they bolt straight in so that was an easy win. I have some time off in July so hopefully ill make some progress 37 3 Quote Link to comment Share on other sites More sharing options...
Popular Post fletch Posted June 15, 2022 Author Popular Post Share Posted June 15, 2022 Also got some evo brembo calipers and 320mm ish rotors. There are a few types of adapter brackets so i need to find a decent set that will pass cert, or buy some 350mm evoX rotors and adapters for the front and 350mm 370z rotors for the rear. My overnight parts from the UAE turned up yesterday with the r34 gtr master cylinder to suit the larger calipers. They look like the will have some stopping power. The current brakes used to run out just before i got to the top of mt messenger. 16 1 Quote Link to comment Share on other sites More sharing options...
Roman Posted June 15, 2022 Share Posted June 15, 2022 Shit yeah, this will be cool! After having not seen clapped out R32s driving on the streets for the last 5 or so years, I've got a renewed appreciation for how nice the shape is. What's the gearbox situation like, is the factory box going to be happy with RB30? 2 Quote Link to comment Share on other sites More sharing options...
fletch Posted June 15, 2022 Author Share Posted June 15, 2022 Yes there is a definite lack of them around now. Its all thanks to the sideways hat brigade and their hectic driving style. Gearbox might be OK. Its a late 33 box i converted to push clutch. One of the main reasons for converting to e-throttle is to be able to limit the torque in 3rd gear, and 2nd if required. I have a complete transfer case and bearing set to give it a birthday and set up the clutches properly, plus a couple of big boxes to raid for parts should i need it. I have been converting 2wd navara box internals to fit RB for a long time now for a bunch of local drifters and have plenty of parts to keep my box going. However, there are a bunch of crazy norweigans who do a conversion kit for the bmw DCT trans. I think it will be about 10k which is a bit much, but dreams are free. Look up HPR tuning, there's some videos of a few 2jz and rb conversions. it looks awesome 7 Quote Link to comment Share on other sites More sharing options...
Roman Posted June 15, 2022 Share Posted June 15, 2022 Oh yeah, I've seen a few vids of Supras with that DCT. Looks amazing! Quote Link to comment Share on other sites More sharing options...

shrike Posted June 16, 2022 Share Posted June 16, 2022 Curious on the choice behind 8.5:1 Compression ratio for the build but keen to see results My AE111 Levin project has the 370Z rear brake setup with the Akabono rear calipers (GT4 rear hubs, toyota highlander bearings/driveflange (5x114.3) a hub ring to center the rotor on the drive flange and then an adapter for the brake) went this way as the internal handbrake on the GT4 and 370Z was similar/same size (cant remember if I worked out it could just factory GT4 shoes or if I needed to add some more lining) Pretty sure I brought the bits before I knew that rock auto was the go but I didn't think $330 was bad for rear calipers back then (2019) https://www.jegs.com/i/Power-Stop/419/S6182/10002/-1?trk_msg=J0VUDM8LCMF4B3PL9EC2QDMGQO&trk_contact=PHST57KEHEJ4JHTH6OUCNU8TO8&trk_module=tra&trk_sid=63E1DGRI1NVOMSC6D65SIEB518&trk_link=1E1GAD39M374BBES33HDTMRMI8&utm_source=listrak&utm_medium=email&utm_term=Product&utm_campaign=Transactional&utm_content=Order+Confirmation Or are you looking at the 370z brembo option?

I think 8.5 will be a good comp ratio. I only want to run petrol. The calipers are all Evo 6-9 brembo. I can get adapters to run the 370z rear disc and the internal handbrake will still work. Plus with the r34 master it will give me a correct front:rear bias without any tomfoolery with a bias valve and whatnot 2 Quote Link to comment Share on other sites More sharing options...
Testament Posted June 16, 2022 Share Posted June 16, 2022 Good work, wholeheartedly approve pulling everything apart and putting it in boxes and piles in multiple locations to ensure forgetting where they go. I'm pretty sure you can make the bakery window without stripping it to a bare shell though so maybe the pies will still be warm when you get there. I don't know anything much about r32/gtr stuff other than the average owner now appears to be an Aussie drug dealer that goes through an engblock per drag event - and but check out kiwiCNC on Instagram guy in pukekohe that makes some hektick cnc gtr gearbox stuff. Probably justifyably hektikly expensive given how many hours probably go into them, but can be filed with the dct dreams. 3 1 Quote Link to comment Share on other sites More sharing options...
Popular Post fletch Posted June 20, 2022 Author Popular Post Share Posted June 20, 2022 Done a few things the past week. Scored a new mirror glass from a wrecker mate. Old one was broken, but it was good to be able to smash it out to see how it fitted in order to avoid breaking the replacement one. Got the larger 17/16th master cylinder. Bad thing is its only a 2 port for ABS models, where i have the non ABS lines needing a 3 port MC. Is there a drill bit available to drill an extra hole? I think i read somewhere that its just a square hole with a the tapered cone inserted to seat the flare. But i have seen guys who have the bling braided lines just double stack the banjo fittings on the 1 port. Maybe i can get a custom single banjo to double female flare fitting? Also got a set of whiteline swaybars front and rear, with the adjustable links etc A nismo coppermix twin plate clutch. Supposed to be near stock pedal feel with 590kw of holding capacity. Had this for a while, got it for a good price a while back ecu, 84mm throttle, o2 sensor. I even found this gear shifter boot in my stash. Who knows when i bought this, but mine is stuffed so its a win When i got the car going, the clutch pedal was always creaky and looked out of place. I decided that since im getting older and have no back issues i would karma sutra myself under the dash and have a look. I ended up pulling the pedal out and sure enough, its from a R33. lol, now i remember doing that maybe 12+ years ago. I dont remember it fucking my back when i did it way back then, but it did this time..... For some reason i tried to buy a new clutch and brake pedal set with all the mounts etc a while back, but only the clutch pedal bracket is available. It would seem thats its all just a bit different The last photo shows a spacer on the front of the R33 pedal box. After a LOT of googling, i discovered that the bracket lives on the firewall on the R32. Mine is missing. Either the auto models dont have it, or i ripped it off when i put the ill fitting 33 clutch in. Anyway, in a stroke of luck, i tried yahoo japan and found someone selling the full set Jackpot! Was pretty cheap too. Somebody tried to snake me in the dying seconds but gave up before my autobid ran out. Phew Also includes the throttle pedal stop and footrest which im missing. AND the brake pedal. Because i did the old angle grinder conversion from auto to manwell pedal pad, and its a bit terrible... 27 1 Quote Link to comment Share on other sites More sharing options...
Popular Post fletch Posted July 25, 2022 Author Popular Post Share Posted July 25, 2022 On the back burner for a few weeks while I try to get another datsun on the road. Took the bottom end plus a spare motor to the machinist to make all the holes round and straight. Also, many of the parts I need/want to buy are/have got really expensive. I feel like of I spread out the purchases, it will cost me less.... Bought some r35 coils and stalk adapters to make them fit. They are a possibly a bit more than I need, but they are new and will work perfectly. Other options might be a bit cheaper, but a bit of mu king around and redoing it when they don't work will cost more that doing it properley. Next stop is modify the sump, strip and clean the head, and maybe buy some shiny bits.. 14 Quote Link to comment Share on other sites More sharing options...
Popular Post fletch Posted August 20, 2022 Author Popular Post Share Posted August 20, 2022 On the go slow for a bit longer to try bit to drain the back account too fast! Bought a hardened timing gear and belt guides as the factory guides are made from plain steel and are pretty thin. They get crushed over time and the timing gear and keyway get flogged out. Also got an upgraded alternator kit. It's an LS alternator. Some simple brackets and it's a bolt on. Also uses the factory plug which is appealing. 140amp so should do the job. Fitted it up to check pulley alignment etc Which was lucky as the thicket timing gear guides pack the balancer out by 3mm. 3 or 4 week wait on the remaining bottom end parts then that can go together. Will start on the head then. Just a stock r33 rb25 head. Will be fitting valve seals, kelford springs, and lap the valves. Maybe cams too, but that's another $$$ 10 Quote Link to comment Share on other sites More sharing options...
fletch Posted December 24, 2022 Author Share Posted December 24, 2022 So the usual 3 or 4 weeks in OS time was 3 or 4 months. I stripped my old head with the hopes of giving it a quick valve lap and send off for a skim was a bust as most of the lifter bores are scored. I must have had some shit through the motor at some stage. Lucky @Ja1lb8 to the rescue with a spare head from a one day project he bought back from oz This is a turbo head - they are the same NA or Turbo, but the previous owner in Oz had copper fire rings added to help seal with a stock gasket. It would be at least 14 years ago that Ray bought it. Must have been before everyone got the MLS also, sadface Anyway, drilled and tapped a fitting for the VCT oil feed like this, but in the new head and dropped it off to the machinist with some spare valves, and a set of Kelford cams and springs. Was hoping to have it back by now, but hes under the pump like everybody so maybe end of january 9 Quote Link to comment Share on other sites More sharing options...
Popular Post fletch Posted December 24, 2022 Author Popular Post Share Posted December 24, 2022 I bought a RIPS sump extension and adapter plate to modify the sump. I have my original adapter plate, but it was a bit of an amateur thing done ages ago. The rips plate has an integrated oil pickup and a few extra features that are an improvement on mine. The plate also has a double o-ring seal, which might seal better than glue especially if im going to probably have it apart a few times - hopefully not, but RB's do love a good run bearing I got a wizard to do the mods to the sump and add on the extension. He made it look so easy and did a beautiful job. also drilled out the oil return holes under the axle tube as they start at 5mm but the last bit of the holes is around 2mm which wont do much 12 Quote Link to comment Share on other sites More sharing options...
Popular Post fletch Posted December 24, 2022 Author Popular Post Share Posted December 24, 2022 I stripped the ring gear off the stock open front diff and installed it with some new bearings onto a quaife torsen lsd. Lots of guys on the SAU forums rate it as the best mod to their GTRs. @Bistro came round for a few beers and gave me a hand to install the adapter plate and test fit the sump. Had to come off again as there was a bit of extra clearance required on some of the adapter plate bolt holes Its all on now, and i fitted all of the diff parts with new bearings and seals everywhere. I jumped ahead a bit and fitted the pinion seal before i measure the end float so that might have to come off again. Fingers crossed its ok. I got the crown wheel backlash perfect at 0.15mm. spec is .13 - .18 Pretty happy with that. Need to paint the gears next and hopefully the pinion is ok and i can seal it up. Its a prick of a thing to fit the diff in so im hoping it does not need to come back out again. The hardest part is waiting for parts. I can buy all the seals and shims i need, but they are usually 3 weeks from overseas. Once the head comes back i can fit that and do some plumbing and fit it back in the car. I might do the transfer case next. Maybe overhaul the gearbox.... Its a slippery slope 26 2 Quote Link to comment Share on other sites More sharing options...
Popular Post fletch Posted December 28, 2022 Author Popular Post Share Posted December 28, 2022 Just waiting for a mate to come round and help set up the diff. Hopefully soonish. I made a start on the transfer case as i was on a roll. The clutches are inside the shiny drum. For some reason Nissan engineers built a great transfer system, then only set it up for about 60% of its capacity. These are the plates out of the drum. You can see they only have a friction plate installed between every 2nd driven plate. Standard there is 7 frictions and 12 drive plates. Max capacity is 10 frictions, 9 driven plates, Plus the 2 end plates. I had another transfer case in stock so i robbed the plates I have changed the bearings and seals over and cleaned all the parts ready for reassembly and done a dummy fit, but have found a bit of an issue with the inner-most friction plate running off the end of the splines. I was going to run the 32 transfer case as it takes the R32 cable speedo. but have a 33 case with some minor differences that make it a bit better maybe. Just waiting to hear back from some kebab shop owners in oz who know about these things before i slap it back together. When i pulled the transfer case off the back of my gearbox, i noticed a heap of magnetic sludge in the back of the box. I have all the bearings and seals to re-kit the box, but not the synchros and they are $$ plus waiting time for japan. A brand new box is $2700nzd in japan, plus shipping plus duty which is around $4500 all up. I wonder if i can get it bought over in a container? 19 Quote Link to comment Share on other sites More sharing options...
