BDA,
Thanks, I understand your point, I have been doing EFI systems for 20 years, was taught to always use AN fittings. I moved away from the SS braid about 5 years ago now use Starlite exclusively with AN fittings. I don't know if you can see in the pics, but the output of the fuel pump is just hose with a hose clamp on the check valve, also the fuel filter is only low pressure plastic. Everything I see in total just makes me very uncomfortable about the plumbing, wiring. The other key point that convinced me to go with the webers is the obsolete ECU, I would end up spending as much on a modern ECU as what the webers will cost. Many years ago before EFI systems were common, I converted a Porsche 924 from the Bosch electro/hydraulic injection to webber DCOEs, and it was a great, simple system, ran great.

I have to admit that hose technology has kind of passed me by since I was an Earls distributor. I am smart enough, at least, to match the hose with the expected pressure! That goes for modern automotive electronics too. I hear of people using ECUs with Webers and assume there must be an advantage - those things ain't cheap - but I just don't see it.

I hope to hear more about your build!

Hi all,
Well doors are nicely aligned, took three of us, all engineers to do it! Learning curve was pretty shallow, drivers door took about 4 hours, passenger only about 20 minutes. I received my 123 distributor, and Pierce has shipped a pair of 40DCOE webers jetted per Wilkins book. I will start removing the injection while I wait for the webers. Thats it for now.

Can you tell us what jets you are using, as I have mixed information on what to use.

Thanks for that.

Is that for Federal cams?

Any idea what sort of BHP that should produce?

I have a free flow exhaust system and manifold (header), and a gas flowed head. Otherwise standard spec with Federal cams.

Currently 2520R pulls very cleanly after about 2500 revs, but below that it seems unhappy, a bit like holding a racehorse back when it wants to gallop off.

My best advice short of tuning on a Dyno would be to install a wideband O2 sensor that can data log to see where your A/F ratio is, also check your ignition advance curve to make sure it is appropriate.

Out with the old, in with the new.
The throttle bodies are actually Jenvey units badged as luminition.
Need to figure out how to put the distributor in correctly, hoping timing marks are on the flywheel.

Wilkrod - I would like to know what boss you have for the steering wheel and column to fit that steering wheel. Do you happen to know what it is or have paperwork on it? I wouldn’t mind doing something like that to my Seven S4.

Marks should be on the flywheel; alternatively, in Wilkins' book, is a diagram of the position of the #4 cam lobes when #1 is at TDC, which you can see if you take off the oil filler cap.  From there, it's easy to preset the dizzy to point to the #1 lead on the cap and install (usually, all 4 wires exist to the rear pointing at the 9 o'clock position (relatively speaking).  Just what I found.

Bryan,
Thanks for the info.
Silly question, on the dizzy cap, what cylinders go to which connections on the cap?
My car didn't use a dizzy cap.
Thanks

The firing order is 1,3,4,2, so it all depends where your rotor is on TDC on #1 cylinder when the cam lobes are pointing apart on #1, and pointing towards each other on #4, seen at the oil filler cap.

Hi all,
While cleaning out the fuel tanks, was looking at the data tag on the NG3 Trans. It is stamped with NG3 S20. Searched the Renault docs on the NG series, and couldn't find that suffix listed. The trans came from Banks if that helps, anyone seen that suffix before?
Thanks

I'm assuming that you've looked at the NG workshop manual (http://lotus-europa.com/manuals/misc/ng.pdf). Of course, there is no S20 suffix. Those tags can be bent up and wrinkled so that the suffix is hard to read. Maybe you could post a picture of your tag so you can get more opinions about what it says.
