Those vents cost me around 6 euros total for all of them 😄 Quote Link to comment
Atomic Posted August 7, 2019 Author Report Share Posted August 7, 2019 The sandwich plate arrived and so did the 90 degree angles for the AN10 tubing: Fits nicely, just needs the mod plate and L-series internals 1 Quote Link to comment
Atomic Posted August 9, 2019 Author Report Share Posted August 9, 2019 (edited) Got the injectors from ebay. Turned out they were not Bosch injectors, but some weird brand called Deleen. I had them flow checked and will be picking the best set of 4=: 4,5,6,8. The injectors were also tested with over 5 bar pressure as I asked, having no affect on the spraying as some knockoff injectors I have seen will get stuck for some reason. Also no difference in spray pattern, the shape for spraying was a nice misted cone for each injector. I will be selling the other lot of 4=: 1,2,3,7 but they need to be flow matched by the next user, so they will be quite cheap. PM me if interested, 50 euros for the lot of 4.

Atomic Posted August 21, 2019 Author Report Share Posted August 21, 2019 No updates in a long time, damn. I finally got myself back in the garage and extended the bracket that's holding the water overflow tank so that it will hold the oil cooler from the other end. Feels sturdy now. The cap can still be rotated and lifted off even when slightly under the oil cooler. The AN10 fitting clears out the rad too. The 9 inch DC fan should do the trick. I need to mount the rad underneath Quote Link to comment
Atomic Posted August 22, 2019 Author Report Share Posted August 22, 2019 Fan is now mounted: Used zipties and rubber washers to tie it down to the rad. Tested it and it pulls air really well through the core, amazing! Quote Link to comment

Atomic Posted October 2, 2019 Author Report Share Posted October 2, 2019 I have been waiting for the custom pistons for 2 months now, they're still being made... The oil pump upgrade project needs a new shaft for the gear to settle in. I got some new gauges for the project, they're the same smoke series from autogauge: I haven't had the motivation or time to do the project until I get the damn pistons from the shop so I can take the engine block to machine shop. I also had to work on my daily driven Volvo V40 as it had some rust spots and I wanted to fix them before the winter. I also need to fix the leaky exhaust piping after the catalytic converter. I could do some bodywork on datsun, but I really don't want to dust around the garage as I have all the engine components laying around. I also received the K-type temperature sensor probes for the exhaust manifold and the TinyOS expander board along with some A/D chips. Oh and then I have an adjustable speedsensor package that will get input from VR sensor from the Volvo rear axle. It will then convert the sinusoidal wave into square wave and amplify it so that my current speedometer can get the correct signal in. But I really cannot test these until I get my motor back together. It might turn out that the engine will start again next year. As the winter arrives I don't want to drive it outside nor tune it in cold weather. It's kinda bummer. OH BUT HEY ITS BEEN 7 YEARS MAKING IN PROGRESS, so I would like to thank all of you for your interest and good comments and suggestions. They have really helped me to continue with this project along the year. The blog has over 1.5k pictures and I have been planning to do some wiki entries later for CAD files I have been creating along the build to make custom parts. So next update will be probably when I get the damn pistons, they better be great 😄 Quote Link to comment
bilzbobaggins Posted October 2, 2019 Report Share Posted October 2, 2019 All good sir. I have been reading this thread for 7 years and love it. Its one sweet B 1 Quote Link to comment
Atomic Posted December 12, 2019 Author Report Share Posted December 12, 2019 Updates! I have finished all the university courses, and I'm only missing my diploma work. I have now been working as a mechanical designer for 1.5 years. B310 turbo coupe updates: New pistons are reported to be ready in 17.12.2019, I should be expecting them to arrive for the christmas then! I'll keep you posted when I get those pistons. The next thing would be to send the block to a machine shop to bore it to oversize. 1 Quote Link to comment
Atomic Posted December 24, 2019 Author Report Share Posted December 24, 2019 Hello hello and merry Christmas! I got a licence plate as a gift: No update on the pistons yet. Wiseco side of things are messy, been waiting for 14 weeks and paid for expedited production run and no pistons in sight... 1 Quote Link to comment
Atomic Posted December 28, 2019 Author Report Share Posted December 28, 2019 15 weeks in and no pistons, I'll call them again next week. Wouldn't believe it's this horrible to get a custom set of pistons Quote Link to comment
Atomic Posted January 3, 2020 Author Report Share Posted January 3, 2020 Wiseco updated, pistons completed. Waiting for a tracking code next. 3 Quote Link to comment
Atomic Posted January 7, 2020 Author Report Share Posted January 7, 2020 (edited) Pistons will be in Europe next week Monday (apparently they were produced in the US), then they will be shipped to me via express shipping. So they might arrive next week Friday? Latest by week 4 I would guess (hype hype) 😄 Edited January 7, 2020 by Atomic 2 Quote Link to comment
Atomic Posted January 13, 2020 Author Report Share Posted January 13, 2020 Pistons will arrive tomorrow, I will take some photos and lets see how they turned out, better be good! Quote Link to comment
datzenmike Posted January 13, 2020 Report Share Posted January 13, 2020 Press in or fully floating pins? Quote Link to comment

Has been a rough one with this order. I need to get the crank, rods and pistons to balanced after and then re-bore the block Quote Link to comment
datzenmike Posted January 13, 2020 Report Share Posted January 13, 2020 As long as you balance the piston and pins, rods with bearings and bolts individually to the lightest one it should be ok. Nissan balances the cranks separately so replacement parts don't upset the balance. Custom made pistons are likely balanced. If using the stock rods they are for sure. Never hurts to check though. 1 Quote Link to comment

I will have the machine shop also check for if the bearing surfaces have something weird. I'm still unsure what caused that sound on cylinder nr. 4. Quote Link to comment

datzenmike Posted January 13, 2020 Report Share Posted January 13, 2020 They all 'float' in the piston, I'm saying 'floating' in the rods as you will need C clips to keep the pin from working sideways and scoring the cylinder walls. I don't know what rods are being used. I honed my rods out with a wheel cylinder hone so the pins would slip in (just barely) so I could use KA24E 240sx pistons. '89 KA24E pistons for floating pins. L20B rods honed so they 'float'. Oil hole for pin Quote Link to comment

So yes if he uses the stock rod he will have to size the small end.... Quote Link to comment
Atomic Posted January 14, 2020 Author Report Share Posted January 14, 2020 I will use the New forged rods that i have pictures on previous pages 9 hours ago, Crashtd420 said: Yes wiseco makes them full floating on the pin and use c clips....

Have you checked anything with the rods? Mine were assembled and the bolts torqued then the big end was honed round and to size. My machine shop was the one who said to check that.... they even did a slight hone on the small end to achieve a better finish.... You may already know and/or have done this but I figure if you haven't its worth saying..... Quote Link to comment

What I just tested with new pistons and pins they work great together, nice snug fit. 1 Quote Link to comment
