Finished Brake and Fuel Lines, Airbox and Exhaust

Almost 5 hours today, interrupted by a long lunch. And many small bits got done!

I've been saying that only the brake fluid line was not finished but actually the fuel line was not completely done either. So today I attached the filler cap on the tank. The bodywork is missing but I plan to drive the car a bit without bodywork fitted, so it's wonderful!
Next task was to bend the small copper pipes to close the frontal brake circuit, possible since I attached the wingstays. Bending the pipes by hand, to fit the tight curves, was actually easier than I anticipated. This job was quickly done.
I had the idea of cleaning the engine. Someone told me I shouldn't do it because the grease and dirt prevented it from rusting. I forgot about the idea. But then, things don't rust in the garage space so the idea came back again. Grabbed a cloth and some petrol and started to clean the engine case, rubbing the dirt off. It was being too much work and sometimes I feel I make up these tasks to postpone starting up the car... Quickly abandoned the idea again and went on to attach the airbox to the car.

My initial idea with the airbox was to attach it with the intake pipes turned down to the interior of the car. Then cut the tubes a bit and link them to a scoop I would fabricate on top of the rad. But when I fitted the airbox that way, the intake trumpets on the engine did not slide adequately inside the airbox. Turned it the other way around to make it all fit nicely but it's temporary... I need to make my initial idea work so that I have less to cut on the bonnet.

After the lunch break, the only task accomplished was to bolt on the exhaust header. It was harder than I anticipated mainly because I was working alone. Had to tie one end of the exhaust tube (after the 4-to-1) to the chassis so that it would stay level with what I needed. then another piece of rope to tie the header part to the chassis to help me sustain the weight. After some wiggling and pushing, managed to get all tubes on the engine holes and bolt everything down. Two bolts were playing hard to tighten but I placed some grease on the threads and it slid a lot better. The wonderful look of the exhaust is not visible yet since I did not unwrap it, to prevent scratches and the likes. Will unwrap it before starting the engine.
Next task will be dash electrics or assembling the battery. And I have to go buy oil for the diff, the brake circuit, refrigeration fluid, fuses and some bolts...

  1. I see you are using the stock air box. Are you cutting up the bonet (hood)?

    1. Initially I intend to run with no bodywork on, to be easier to fiddle with the engine and pipes.
      Later on, I'll have to cut the bonnet and "hide" it with a scoop. I hope to put the airbox the other way around, with the air intakes pointing opposite to the exhaust, to reduce the amount of cutting I'll have to do.
      I admit I would prefer to be able to cut and shape the airbox to, keeping the same volumetric size, make it fit under the bonnet without cutting. But I doubt I can manage it (not sure if I'll even try).
      I don't want to drop the airbox because I don't want to have to jet the carburettors and I need to keep the intake noise down (still unsure if I'll try road-legal tests in the UK or Portugal).
