Re: IRS

Hi
Would this tool work with the S3 IRS. I’m not sure what the rear ARB bolts are?
Any pictures of the thing in action
Cheers

Re: Ignition Amplifier

Whilst your in the ignition mode. I fitted the sng kit and ran it quite a while with no issues. Then I started getting moisture or vapour buildup in the distributor cap, leading to missing. Jaguar had issues with distributor caps exploding due vapour leaking into the cap, through the distributor. So...

Re: Ignition Amplifier

Hi Colin
I’m not sure what’s involved, mine was fitted by British vacuum when they drilled my carb as well.
British vacuum are very user friendly and will answer any queries.
Their website is a mine of useful info on vacuum advance modules, and distributor numbers etc.
Cheers

Re: Ignition Amplifier

Hi guys The amp from SNG does use the HEI chip the same as in the later cars, and the distributor is rebuilt to HEI spec, but with a vacuum module as per the original system. It’s easy to change to a vacuum advance module at a later stage. British vacuum can supply suitable ones. I can vouch for Bri...

Re: Ignition Amplifier

Hi Des If it is the original amplifier OPUS, probably still in the valley, or maybe shifted to the front rail, then don't waste your time fixing it, replace it with the later HEI amp and dizzy as fitted to the later V12's These can be sourced from wreckers. The OPUS is notoriously unreliable, and pr...

Re: Am I a little hot?

Hi My series 3 which has thermostats fitted, and a new radiator, runs with the needle on the R of normal, and never shifts much at all on the open road. If crawling in a line on a hot day it moves slightly towards the A. The fans come on just above the R. I did have a manual gauge fitted, and the R ...

Re: Manually setting the timing?

Hi guys Steve, I also fitted the SNG ignition upgrade, you’ll like it. A couple of things with it, they recommend a very conservative static timing setting, 8dtdc I think. When you figure out where TDC is you may wish to set 12 deg BTDC, which was the jaguar recommended setting. The distributor fron...

Re: Manually setting the timing?

Hi Why don't you make a double stop measuring device from an old spark plug. Knock out the center, and braize a nut to the top then use an appropriate sized bolt through the nut. This simple device will allow you to accurately find TDC on the No1 cylinder, front right. Then you could either make up ...

Re: Timing a v12 with no timing marks!

Hi
Be careful if using a dial gauge to set TDC. Do not turn the engine backwards as you may damage the timing chain tensioner.
Use the double stop method, plenty of posts on the subject.

hi Algrant All good advice so far. Bringing GBP to Nz will give you a good currency gain so buying whatever services you need down here will be reasonable. There are a number of top quality restorers, think Beacham, or Tempero at the top end, and also plenty of old school mechanical types that can f...

Re: s3 auto to manual conversion.

I think you would be disappointed with the manual 4 speed box. I had one in my car and in 4th it was revving too high for my liking at normal road speeds. In my case I didn't have the Overdrive box choice, so wound up fitting a Getrag 5 speed, which I like, but it did need an adaptor plate to mount ...

Re: JD40 Sprocket Retaining Tool

Yikes
how about one of those telescopic antenna like devices with a strong magnet on the bottom, some are stronger than others.
Then when you have lifted it a hooked wire may be able to be used.
Good luck

Re: opus ignition system

Hi Colin, As usual our resident expert Marek has posted the good gen. Here are a couple of websites I used to research when I was doing the mod on my car. The british vacuum site is useful to ensure you have the appropriate vacuum module. Following his advice I wound up using the 54405202 unit which...

Re: opus ignition system

Hi Philip
Isn’t the issue that, in your case, with vacuum still being provided to the advance capsule at idle, then extra advance will be provided at idle, which I believe is undesirable.
Well jaguar thought so which is why they set up the system to avoid this.

Re: tyre pressure

hi Definitely have a look at your mounting of the underbody mufflers and exhaust pipes. Make sure the mufflers are right up in the cavities. And check they are the same oval shape as the OEM mufflers, I'm assuming someone has replaced them at some stage. The pipes where they go under the IRS should ...

It does give you a rebuilt dizzy as well, which as we all know generally benefits from a rebuild. This kit is still has a retard vacuum capsul...

Re: Power steering problem

Hi
whilst you are on it, search the S3 forum for "pressure reducing washer". This mod is one of the best, and simplest, you can do for your S3. No more vague steering in the corners.

Re: sound of the v12

Hi Barry,
where was the HP increase?
Some have suggested that it is only at high revs, an area most of us are unlikely to use often.
If it was in the mid range it would be an advantage. I certainly would like more in this area for overtaking.
Cheers
Mark
