Works for me to get to the Swift page but if I click on the actual items it takes me to the contact page.

That’s really nice. Something to aim for?

Didn’t come from me originally. Both my usual RR man and the owner of the place I bought the AEM, soon exchanged for the Zeitronics and also a RR tuner said the same thing. Bosch would say that…… 4.9 is meant to be an improvement. Maybe it is when installed and mans to OEM standard. Sensors are cheaper than 4.2 at least.

Are you originally from Norfolk......?

LS4.9s do seem relatively fragile. My RR man insists that the old LS4.2s are toughest of the lot, even if they do need free-air calibration from time to time. Certainly my old Innovate LC-1 with LS 4.2 managed about 20 years before it started doing random things. Ripped it out and promptly had recurring issues with AEM plus LS4.9 (though not actually Bosch sensors) so that got fired and now have a Zeitronics unit which has worked well for a couple of years now. Irritatingly my old Innovate LC-1 and original 4.2 sensor has gone back into service on No 1 sons FrankenSpit and works fine..... That sensor has survived some pretty rough treatment including many miles on an engine that burned alot of high zinc oil!

Skinflint that I am I would be modifying the Triumph flywheel…… I should done it on my GT6 conversion - would have been very much easier!

FWIW, sitting here on my sofa I’m more inclined to using the flywheel that matches the engine and making the clutch fit that. If the basic clutch size is about the same then you may well be able use the pressure plate that matches the flywheel and just substitute a friction plate of the right (or nearly right) diameter and correct spline for the gearbox. Have successfully used this approach several times. Vitesse runs a Toyota friction plate with Triumph/Saab/Ford pressure plate and GT6 similar but Mazda friction plate.

So, seems my earlier comments are based on the older and weaker 020 gearbox as used in Golf GTI 1,2 & some 3. 02A is apparently usefully strengthened and uses a hydraulic clutch with more conventional flywheel/clutch arrangement. Presumably this is what is in our 180bhp 5 speed TT (not busted yet) and even my Octavia (not busted yet but not as quiet as it should be). Should be strong enough for your purposes. Edit: TT is actually 02J which is generally similar but with improved shift mech. Might be another option?

Interesting….. but don’t the 02As use that weird backwards flywheel/clutch with the pushrod in the input shaft?

Be careful with VAG boxes…. They also have many casing and ratio combinations with much interchangeability at component level. The 02A isn’t especially strong either. I had to rebuild the box on every GTI we owned and they weren’t being abused. Though it is at least better than the chocolate 085.

Errrm….. drawing….. yeah….. I’m from the “hack-at-it-until-fits (or bust beyond redemption) as school. TBH, the approach here so far has been to hack off the MX5 bell and attach something else so the flange dimensions haven’t be relevant. I do have an uncut box here though if you need particular dimensions.

Yeah, reckon the horses are awake….. Probably several fields further away now too 😀 Nice positive update. Good to see you have the throttle control sorted. That exhaust merge does indeed look like a sod to weld! Suffering for your art…. On the injectors, what fuel pressure are you running and could you not increase it to extend your injector range? Interesting about the gearbox and the bellhousing/front cover. I’ve been wondering similar about my MX5 conversion where the front section has the bell cut off and an adapter ring welded on to take a Triumph bell. It’s not so much a shifting problem (the homemade shift mech would probably get the blame anyway), more that both gearboxes I’ve tried have been disappointingly noisy (grizzling like a well-used Triumph box in all indirect gears) even though both boxes have seemed decent. Mine is supported all the way around so it would have to be welding distortion. Jacking yours up in the centre has got to be worth a try. Is it a big effort to add per support if this proves to be the problem?

1.9TDI conversion? I do like this thing. Good to see it getting such a detailed makeover 🙂

So…… I have had similar many years ago with my Triumph Herald. Basically whenever I caned it with less than a 1/4 tank it would drop onto two cylinders as there was only enough fuel getting through for the front carb. Sometimes it would just do it without being near empty or being caned. Never was much in the fuel filter apart from a few fine fibres. I carried a bicycle pump for the specific purpose of blowing out the fuel line. Was very irritating but I could never find anything in the tank. Eventually I took the tank out and after much flushing a swilling, got out a 60cm length of fine fabric tube. I think it must have been the fabric outer slipped off a length of fabric covered hose (maybe even a present from the cunt who syphoned my tank one night). Certainly it was nothing I’d dropped in there and it had been previously fine for several years. So sounds like you have something similar. On a newer vehicle I’d suggest a problem with a filter sock on the pickup but I doubt this would ever have had one. I suppose it’s also possible there’s a nice little collection of “solids” that keeps rolling back into the pickup area and obstructing the outlet. Or have you/PO used slosh sealant on it? Do you have anyway of looking into the tank (sender port etc)? Otherwise may have to drop it out and swill it out….. Probably not something you really wanted to do! ☹️

Classy looking repair work been happening there. Looks excellent. Same guys doing the paint?
