Not seen in these pics are the exhaust branches that I had wrapped in with the new non-asbestos type of bandage. It is now glassfibre based I think. Hopefully it will work as well and last as long as the older asbestos types.

It is not for any performance advantage that I have ever noticed, but rather to try and keep the underbonnet temperatures down. Things gets very hot in there under sustained running under power, so any and every bit helps.

Since the weekend, I have been crawling around under the car mostly with the exhaust system. No pics so far, I am not good with pics under the car. It would in theory be a lot easier to get it done by an exhaust shop, probably. But then I would first have to have the usual argument with the resident expert to get it done my way and probably still be unhappy with what I get and have to pay too much. So I am building it myself. In any case, I don't feel like the schlep of getting the car to such a place at this time of year.

Well, that is it all up to date now. I plan to try and get the exhaust done before I close up shop (so to speak) for the year. I will update as things happen, hopefully I can wrap up the Sierra quickly and get back to the Cortina build very early next year.

Below, just so this post is not without some pics, are the 5 engine bays "Old faithfull" has been in:

Early days, in JSCustom's drag Prefek.

Back with me, still in the Prefek.

It then changed hands a few times, ran once I think (so technically 6 cars) in another Sierra up in JHB somewhere.

Back with me again, this time after a stripdown and extensive rebuild, in the Fine Car Sapphire.

In the Sapphire it once lost a welsh plug, got so hot both heads and the block cracked. Extensive rebuild followed.

It was the first engine in the LS Capri.

The Capri got a new engine and after a brief rest on the floor again, it found a home in the Taunus.

When the Taunus got stripped, it found a home on the floor again for a couple years and now it is in the Sierra.

It had not been opened at all since the Sapphire days (2010 season in fact), so I am crossing everything it will run for at least a couple meetings.

Last update for the year.... and in the spirit of Xmas, I'll start with a pic of something shiny and bright.

Ok try to ignore the mess my workbench is in at the moment, that is not so shiny and bright. This is the tailpiece for the Sierra, tacked together and ready to get welded. It is a big diameter piece of SS piping, much bigger than is actually required, but I like the look of it and the sound.


Here below is about as deep under the car as I have been with a cellhphone to snap a pic. The front sections all propped up in place and tack welded together.

Yes, it is a great deal of fun crawling into the confined space with a welding helmet on and trying to get in a position to weld. Thank goodness for auto-darkening helmets, it did take some of the guess work out of welding.

Pipe diameters, the first bits from the headers are 57mm, then joined by a custom made Y-piece. Ideally for this type of engine a single 68mm from there, but non-availability of silencers and bends in 68mm meant this one is 64mm. Still OK, not that much in it in any case.

From after the silencer (oval, about 400mm long) it starts its turn still in 64mm and then I added the shiny 76mm piece. The joint ended up being a bit messy, but it will work OK. I may go back there next year some time to neaten it up a bit.

And here below the bit I hope most other racers will get to see! :lol:

I did start it up again now that the pipe is complete. Sound is about as I expected and very similar to the Sapphire, as it would be since the engine is the same one and the pipes very similar.

So that is it for the year, I will take time to clean up the mess a bit before going on holiday. Hopefully next year I can wrap up the last bit of work on the Sierra (still have to make a shortlist, but it is close enough for that now) and get stuck into the Cortina.

KSF, a fantastic thread. How do you manage to hold down a day job with all that activity? :lol: Imagine the thrill of getting the car on track and then competing against the LS Capri you built. Looking forward to seeing how you manage to race the Sierra and Cortina at the same time in the same event...... 8O

Back from leave and slowly getting over the shock to the system of having to be at work again. :? :x

KR, the day job interferes for sure! Pity it is required to fund everything... I have been wondering how to race them both (one day if and when they both run) at the same event. Maybe if Classics and Fines once again split into two separate races, but even then it is a tall order to get two cars there and ready etc. More likely I will have to decide one day which one to keep and which to sell on.


Work on the cars only sort of just started up again. I needed Monday and Tuesday to get over the post holiday blues. Last night I took off the Sierra's wheels (loaned from the Cortina) and loaded them and the new mags in the car to be swapped over today. Pic below the whole lot is in the back still.

So tonight they can go on and hopefully will give me enough clearance to the arches. I also took out the front struts again, have to adjust the rideheight by quite a bit and I hope I can still get it done with the springs I have. I might have to give up on the big springs and convert to the small diameter springs as it just makes it much easier.

KSF , Absolutely fantastic thread. A wealth of info,

A question on the Uno pickup and module, I located the module and pickup sensor in a local spare shop however the chopper/rotor no one seems to know where to get them? any help?

A comment on wheels, I have a 2.0 i GLE auto, and on the 17"s wheels it is a bit slugissh. The 16's do run a lot better, with a 195/45 on front and 205 /45 at rear. I managed to get my auto down to 180 on the flat before the gearbox limited out. These are the old Hockenheim 1. Their offset is perfect for the Sapphire albeit a bit of a heavy rim.
Can't do that with the 17s. These modern China made wheels buckle easily , and clear goes yellow very quick. (Cant be teh dogs pee)

Not that I know of? Did you see another one somewhere? I know Arnold Lambert recently bought the Poulter Gunston car, so it should be down here in the Cape somewhere now.

I have not found out where the chopper comes from no. Maybe a call to that shop in JHB will help? It was mentioned in the thread about the conversion, think it was under 'Technical'.

The Sierra/Sapphire seems happiest with an overall wheel diameter between 580 and 600mm. How one gets there is probably less important, but a 17" with so little rubber on is just looking for buckles and dents on the average SA roads. I do see them with 195/40 rubber on regularly though. Happy medium/compromise is probably a 205/50x15, or 205/45x16.

Saturday, Passion for Speed. Thought it was your car, 'till I realized it's a 2 door.
