Hi

Does a swaybar improve the driving of rhe Pi and does the Stag one fit to the mk2 ? 

Thanks

According to Rimmers website, Stag antiroll bar is different (different part number).  Rimmers also do a mounting kit, but you would also need to replace the drag links for the type with antiroll bar attachment points (not included in the kit).

Cool.

Thanks for the link.

Triumph Mk1 Estate (2.5PI homage)

Yet another plate welded on to fix a few small holes in the boot floor area. Fuel tank pin prick repair hadn't worked, tried again with another compound, that didn't work either, even with the use of heat gun to warm the area & material up nicely, I have another tank inbound from Lloyd Reed, hopefully that will sort the issue. I need to cut the later tank flange down slightly to get it to fit, luckily there is around 1" of flange and I only need to remove half of it along one edge. The CW 6-3-1 exhaust manifold fouls on the PAS pipework, a spot of persuasion created a bit of clearance, not a lot though, I am concerned that the fluid might boil. The long radiator hose/pipe/hose from the bottom up to the water pump housing is now fitted & runs clear of the pump, this was much easier with assistance (thanks Calvin Packwood). I then did a test fit of the exhaust system. I think I know how it goes together now, will take short front link pipe to have sensor bung welded in this week and fit the exhaust properly next weekend. The fuel pump is now fitted, some CAV filter fittings inbound, will fit that once tank is in situ, then mount diaphragm PRV wherever makes sense.

Today I did....absolutely nothing, it feels like this conversion project has taken months, it has certainly consumed all my free time for too long, sometimes you just need to take a break, I'll get back to it next weekend, hopefully it will be less damp & grotty.

MK1 PI Estate (homage)

I took today off to crack on with the PI conversion on the Estate:

Fuel supply & return lines now run out, still need securing however.

Later fuel tank painted & fitted

CAV Filter housing mounted & diaphragm PRV fitted, all plumbed in

Exhaust loosely mounted front to rear. 

A good day's progress, I will look at the electrics tomorrow, in principle I could try to fire it up this weekend but I have a schedule and I think it's best to stick with it, there are known gremlins, the PAS pipes are leaking, need to put PTFE tape on the fittings.

Iani,

Please keep up the reports!

Just an idea, from my own conversion on my Vitesse to Pi.  I realise that mine was for an extreme purpose, motorsport, but I soon  realised that Triumph had made inadequate provision for fuel slosh in a half empty tank.     Unlike carburettors, that will exclude air bubbles that get into the fuel feed in the float chamber, Pi has no such provision.   The volume of each squirt from the injectors is tiny, and even a small bubble will mean that only air comes out!  

This usually happens just as you put your foot down as you exit a corner, the engine dies.   If you keep your right foot down and left foot up, then  it will usually restart as inertia keeps the car going, the air is expelled and fuelling returns, but it's a frightening experience.    You must judge if your driving style and intended use makes this likely, but I found that a swirl pot for the fuel with a lifter pump to keep it filled abolished this effect.

I used to run Lucas PI on my TR6 John, so used to the tank foibles, I tend to keep a decent level in the tank to avoid issues. I am currently unable to fit the spare wheel in the well, if I can't fix that issue then I might put a swirl pot in with a lift pump as I'll have plenty of room for it, would then just keep spare in the load area.

Depends if you find the car leaning excessively at the front when you go into fast bends?

The Estates have a higher CoG than the Saloons (due I am told to the amount of lead used in the body)

Yes. The car leaning a bit on direction changes and curves but suspensions are tired.

1st i put new struts to see how it behaves and then i will see if sway bar is needed to improve.

[Richard B]

It can be quite un-nerving the amount of lean. This is managed by the springs, not the dampers. Chris Witor sells the pieces to weld onto the Engine Cross-Member and the Drag-Struts if you want to convert your existing suspension.

I would note that the drag-strut strengtheners are also worth while if going downthis route, as an anti-rollbar puts more load on the drag-struts.

Triumph 2.5 PI Estate (Homage)

The light at the end of the tunnel is getting a bit brighter:

123 dizzy timing set, fuel pump wiring run in loosely, will get it under the carpet when I can move the car outside. Fuel lines all connected, still need securing but all connections in place. Awaiting tank to filler cap hose to arrive, hopefully tomorrow, need throttle cable, will hopefully have that this week, aiming for first fire either Xmas Eve or Xmas Day, that will be a great present.

Today Tim Ward and myself (mainly Tim) fitted one of Dylan Day's throttle brackets to the mk1. This takes the place of the linkage where the cable attaches. They're very well made, throttle response is instant and the car feels fantastic 🙂

Dylan still has a few left. His number is 07583590581 and they're available for £60 + postage. I'm not involved at all apart from being a happy customer, and I said that I'd mention it on here as Dylan isn't a CT member.

Copied from the members only section as Dylan has said that he doesn't mind his number being on here

Mk1 2.5 PI Estate (homage)

After a few stressful days, with a lot of encouragement from various CT members, tempered by my inability to follow instructions properly, I have been struggling to get the car to fire. The injectors I was using were reconditioned ones, but they had been sat of a shelf for several years, I swapped them all out for a fresh reconditioned set, still no luck. The fuel pump that had been checked over by a specialist proved incapable of producing more than 100psi and frequently reduced to 0-40 psi, useless if the system was to work. Martin Giles (t/a Fred Milturn) kindly swapped my pump for a used one he had, it produces 120psi and a constant 105psi once the PRV was set, still no firing.

Suspecting that the newly reconditioned MU might be faulty, Martin drove over to help me remove it and he would take it back to KMI, with Martin's assistance we discovered that the dizzy was 180 out, entirely as a result of the aforementioned inability to follow instructions! Once we'd moved the plug leads round, the car fired up fine. Tomorrow's task is to remove the dizzy & MU, reposition the drive gear and refit everything in the correct orientation. 

I'd like to thank Martin Giles for his assistance, he drove half way to meet me to hand over a set of recon injectors, again to swap a fuel pump and finally drove to my house to collect a suspected faulty MU. This is customer service way beyond the norm these days, I have bought several items from Martin over the last few years and he has always been a pleasure to deal with.

I've spent the morning dismantling a spare heater unit with the intention of fitting it to the Saloon (was known as Moby, now called Casper). The one currently in the car has a sheared linkage pivot.

Edited December 29, 2023 by Rubce

[DGF]

All welding, from B post back has been done , underside under sealed and finished 

some minor finishing touches to rear wing’s left, before it gets painted 

[WIMPUS]

Last few days been helping a friend with some jobs on his TR6.

New radio, speaker panels, speakers fitted and.. some electrics done.

Throttle pedal/carb linkage had play, so fixed that.

As this is an no 25 TR6 build, it used the carbs, throttle linkage, emgine and half the electrics of a TR250 😅

But there was more to do.. 

Cooling system was like mud, no heater.

But does not overheat.

Flushed it good, then water with washing soda in it.

After 10kms.. mmmm 

But heater starts to work better !

Today the car has done some more kms.

Tomorrow another good flush and again washing soda in it and a drive.. then will see 🙃

[WIMPUS]

Yesterday flushed the TR6 2 times and then back to regular coolant.

On 2 testdrives the heater was starting to work better.

And temp stayed a bit lower to.

Hopefully the coolant will stay clean now.

In company of Fox ofcourse.. 

Pretty much original paint under the bonnet, surviver look + ex. usa no. 25 build, made in October 1968.

The engine etc was build by me in 2017.

+ this engine has his crank grinding into the block, pressure clutch and engine stopped turning !

Yes it was bad, but machine shop saved it.

Mk1 2.5PI Estate (Homage)

Rain prevented my taking the GT6 out today, I decided to wire up the AFR gauge, video shows reading 1 minute after starting the car & choke fully off, not too bad given no tuning performed yet. I have also removed the Mk1 2000 throttle pedal, I have a Mk2 cable pedal to fit, no access until I get the car out of the garage though. I also ran in another wire for the 2 speed wiper motor and fitted the 2 speed switch, it works, another win. I also fitted an oil pressure gauge and made up a new reverse light switch loom, I thought the one on the 'box was sound but a section of the wire fell off, best to replace with new.

 

[iani]

Mk1 2.5PI Estate (Homage)

Minor progress on NY day, new reversing light loom fitted to gearbox & OD wiring connected, I had to make up a small extension loom to reach the switch wire, J-type OD loom & A-type column switch, so non standard configuration. I then managed to drill the holes for my new throttle pedal, unfortunately I couldn't fit it due to needing another pair of hands, I'm getting tantalisingly close to being able to drive this car, hopefully the next two weeks should see it coming out of the garage.
