FCR SR Video 1

February 7, 2013

So it runs and the bowls don’t leak! I’m having a little issue with the throttle returning to idle even after a new auxiliary spring was added. Soon I will pull the carbs down and service the main return spring assembly.

I plumbed in a new low pressure (2-3.5psi) fuel pump and a Holley fuel pressure regulator. There is also a splitter block in there to feed the excess back to the tank. Remember that these carbs are built to run on gravity feed and hence really dislike pressure into the bowls.

I make many apologies for the visual and auditory experience of this video:
1) Damn that engine bay is ugly! It’s a work in progress and the carbs have been set up for initial testing and tuning without to much thought towards cleanliness and presentation. This will come as soon as it runs nicely.
2) Canon 7D microphones and controllers suck and I wish I had a better way of getting crisp sound.

I drove it up and down the drive way a bit bit and it definitely needs a tune but it runs fairly nicely and sounds great!

FCR41 DUMMY FIT

February 2, 2013

Here’s a quick (and quite rude looking) photo of the FCRs on the current SR20. I don’t know how easy it is to do in the huge Silvia engine bay but note to self: never attempt to remove/fit stock plenum in the Datsun ever again, take the engine out. That was far too frustrating.

With the stock SR, I’ve fitted the fuel filter in the engine bay and everything fits nicely. Trying to squeeze in a fuel pressure regulator, the fuel filter and a line splitter into the engine bay between the carbs and the brake master cylinder is a real hassle.

With some luck and some new fuel line, I might be able to try starting it tomorrow though I have my doubts. Fingers crossed.

FCR41 SUNNY TRUCK

February 2, 2013

Oh no, what have I done!

To be perfectly honest I was thinking about selling my truck this year and focusing on racing motorcycles… but something came up. Primal lust kicked in and here I am. They’re KEIHIN FCR41 flat slide carbs and they have me pining pretty fierce.

The unit has been sitting for years without use, after being in a S14 FL and then a rally escort project that was never finished. As I expected, the engine has a few issues, mainly surface rust on the cam lobes and I expect the bore too. It came with: a Cusco/Jasma exhaust manifold (which I will post about later), oil filter sandwich plate for an oil cooler, a Holley fuel pressure regulator and braided lines, a fuel line splitter, ecu, loom, and a modified coolant outlet.

I HAVE SOME 20V 4AGE ITBS ON A CUSTOM SR20 MANIFOLD FOR SALE IN NEW ZEALAND IF ANYONE IS INTERESTED
