    Are you using mig for ss welding? I had an issue with my exhaust manifold when I didn't have teflon coated inner tubing and the ss wire got stuck once in a while and that got me really annoyed and spattery results from time to time.

    Hmm, I cannot seem to find any suitable 2 wire PWM IAC modules for the throttle body that I currently have. I was thinking if I should just buy a cheap one that is commonly used for example in volvo 740. That would mean to block off the one in the throttle plate and make an additional routing to the plenum for the valve. 🤔

    Cut the fuel tank finally open to see how it looks like: Doesn't seem to be that badly rusted, maybe a treatment similar to POR15 will do the trick? I had some soapy water when I did the cutting, the bottom of the tank seems to have some black sludge 😄 Plus the return line has some fungus?!

    Used the new long neck air tool to make the air outlets flush to the inner walls: And got more argon:

    Sketched out a holder for the fuel rail: And hood still goes shut well:

    List to buy: AN6 to 3/8'' aluminiumpipe 4 AN6 straight PTFE 6 AN6 180 PTFE 1 AN6 3/8'' NPT 2 AN6 PTFE Nylon hose 2(m) AN6 Weld plug (steel) 2 And then 10m of anodized aluminium hardline. That should cover everything about the fuel delivery and return to tank, hmm..

    Need to order more AN fittings. I'm planning to run hard lines from and back to the fuel tank, they're fully anodized in and out and compatible with RE85. And I swear that 1/4 thread fits the turbo water inlets, but I'm starting to lean towards AN4 fitting because of the cone, any ideas? Mangled the manifold into better shape, but still needs a lot of work. Wired the injectors tho: Will be buying a long neck grinder so I can port the whole intake system: Also also, changed the title of the thread. I have some future plans that will make it sound even cooler 😈 (still lots of empty room in the engine bay...)

    Made some progress again for the plenum: I need to do touch ups for the welds, but its starting to take its final shape

    Cheers! It wasn't the first try and has been on going project for around 1 year. Sadly that isn't the case since the piping is almost at its limit where I currently have them. If you would be able to squeeze intercooler there, it would mean that the intake should run really close to the valve cover. I think I will cover up the 'lag' in the future, I have a lot of ideas to add more power + complexity to this build once I get it on the road! Love your work too, I like how you were able to make multilink suspension at the rear, I have butchered two of the wagons you have currently, the engine is from one of those.

    Eyy, it's weekend again! Got 8mm thick aluminium plate and drilled a 55mm hole at the center and thread tapped 4 holes for M6 bolts. Welded it up and mocked the pipes with some tape to see how it would look: The plenum will get shortened next and then I need to drill holes for the over going pipes. Then I need to figure out some supports for the plenum because it's getting quite heavy with the throttle body. Started cleaning the smaller pipes a bit before welding them in, will continue more tomorrow!

    I'm so happy with the results. I will do a lot of clean and polish on the intake manifold still. I wasn't able to weld between the two pipes so well, so I'll be using some heat/chemical resistant 2-component epoxy to seal everything, or weld it from the inside once I have ported the flanges Also need to weld the fuel rail mounts to the manifold too. The plenum is looking like this at the moment: It's missing some 6-8 mm plate to adapt the throttle body and then I need to drill holes for the intake runners. Then I need to make sensor adapter etc

    New shocks came in, and oh boy they're nice! 18+18 adjustability for compression and rebound: And they fit perfectly on the datsun! I also saw'd the intake manifold yet again and started welding again. Thus far everything is going nicely, more pics later

    Got the springs installed, they fit nicely. Need to install shocks tomorrow, they arrived late today

    Got myself new custom rear springs. I should now have 4kg at front and 3.4kg at rear (worn out ones are old cut rear springs): Hopefully i can test fit those tomorrow

    Seems to fit. I had some issues when welding pipes 1-2 to the flange. The pipe 1 warped in the process and I need to cut it off and start again.. I swear this is the most tedious phase ever.. I will be so happy when I'm done with the intake manifold, its really the worst..
