Twin SUs move a lot of air, but there’s not a lot of room for a decent air filter. The factory pancake filters are a bit undersized, aftermarket oiled foam filters are often worse, and, while K&N filters have a bolt-on appeal, I don’t really trust them. Their marketing seems a bit snake-oily.
Plenty of other cars use disposable paper air filters, I’m sure I can find something common that will fit…
Oh look. It’s a filter from a 2.5 litre V6 Nissan Cefiro, also used on various other models. I wonder if it’ll fit…
That counts as fitting to me. Time to start designing the housing using CAD (Cardboard Aided Design).
And now translate it to steel:
The lid is a little more involved, since it has to clear all sorts of somewhat important things. No worries though…
A cold air intake from the wing, a lick of paint, a Leyland sticker of dubious authenticity, and we’re done!
(Ok, so that actually took 5 months from beginning to end. Here’s what it looked like for a while:
Not pictured here: building a new kitchen, landscaping the garden, various other things that had been put off for too long.)
The standard carburettor fuel pipe is ugly. Also, the one on this car is a bit rusty, but it’s the ugly that really bothers me. Time to make a new one! But first, the original piece:
It just hangs between the carburettors, with a few random wiggles to clear various obstacles. Ick.
Some bundy tube and a bender to make the new fuel line…
Flare the ends so the flexible hoses don’t fall off…
Mark the position for the incoming fuel branch…
Attach the branch (silver solder is lovely stuff)
Tidy it up, plate and polish it, then check that it fits. If it doesn’t fit, stomp on it and repeat the process (Frustration, rage, resignation, and repeat of process not pictured here).
I’m starting to get paranoid about the engine fitting into the shell- I definitely want to avoid having to adjust the body once it’s painted. Time for a test assembly!
First we have to install the engine into the subframe.
Then the wheels go on..
It’s so clean and pretty!!
Engine and subframe supported with a very special stand, lift the front of the car up, and lower onto the engine. Carefully. With maybe a little bit of swearing when things scrape.
Lovely. Now we start fitting all the other engine bay bits, like brake and clutch cylinders, radiator, and radiator expansion tank:
