Aren't gears cut helically to reduce noise/improve transmission efficiency though? And are they always cut the same direction (clockwise/anti-clockwise/however you define the direction of cut)? Or just fit a straight cut gearset - problem solved. If there was ever a problem in the first place. To reduce noise. They are actually slightly less efficient. True straight cut is very noisy though. Years ago a mate had a road going hiilclimb Mini with straight-cut everything. What with that and the Weber in its box that was a seriously uncivilised form of transport. Proper quick though.

The laygear cluster will see rotating thrust loads and they will be reversed with reversed rotation. Not familiar with Subaru boxes, but on Triumph boxes they have a big washer at the front and a smaller one at the back - presumably this reflects the relative load directions. On that box it would be fairly easy to swap them over...... Imp with a flat six will be Impatient (in traffic)......

Just do it man - it'll be fine...... probably

in my experience of peugeot tappets the squishy ones are the problem not the firm ones, unless the firm ones are fully compressed and stuck. True on VAG ones as well Nick

It’s a difficult one. Depends on whether you view it as a banger.... in which case bangernomics principles apply, or whether you view it with any affection and are prepared to more in.
In either case it’s always quite hard to judge. In my experience, failures tend to go in waves - you seem to get expensive patches where several things happen at the same time, followed by a long period of reliability. If you’ve owned the same car, or even the same model, for many miles/years you’ll get to know their weaknesses.
I have a ‘96 A6 avant which bought in 2003 at 7 years old and 112k. It passed the milestone of 333,333 last week. That mostly eats front suspension, front wheel bearings and rear calipers, but the major mechanicals are still good.
It’s getting a bit tatty, one of the exhaust joints is almost rotted away, needs the rear beam bushes changing and the clutch is getting a bit near the end (rubbish! you’d think it would last longer 😛), And being a dirty old diesel it’s being banned from more and more places, so in bangernomics terms, it should go, but now I have this nagging question....... will it make 400k without engine work......? And logic goes out the window.....

Well..... and here am I stressing about how to knife and fork an MX5 gearbox onto a Triumph 6....... Minor problems.....
I shall follow this with great interest.
BTW, the BMW K series TBs are separates joined by a pair of bars. Hard to narrow but easier to stretch. If you want to know their native spacing I can measure it for you as I have 6 joined in a row...... and some extras. IIRC the K750 ones are smaller (32mm?) than the the 4 pot ones which are 34mm. Note that they do not include injector pockets.

US diesel is reported to be pretty rough stuff so seems little point in wasting your money on premium diesel.

Believe the Zetec SE 1.7 specifically is the one with no spigot hole (or a very small one) but the rest are “normal”.
Really trying to establish whether I’ve got any chance of getting a Suzuki m series on the Samurai / SJ413 ‘box without resorting to buying one to try.

I like these. A friend had the saloon version of these in 1987/88. 100GL in orange bought for not very much because it needed welding and Audis were deeply unfashionable and regarded with deep suspicion by the banger market. It was quite a beast and two orders of magnitude better than the assorted British tat the rest of were driving (Riley 1.5, HB VIva, Herald 1200, Mini 1000). It did like a drink and ate brake pads, but then he caned it without mercy all the time.

Use an Audi Quattro rear diff they require reverse rotation input iirc?

Sad sight.....,
As has already been said, unless you just want the thing gone, DO NOT let them take it away, as if you do, you will never see any part of it again. Get it put safely under cover and have them come to it for inspection. If being kept away from home make sure that those where it is being kept know that it is not to be moved without your express permission.
Looks like the shell and much of the running gear could be saved.

Thanks for the reminder about the 106 link. I’d forgotten that and will check back.
We have an RX8 5 speed gearbox......... same comments as the MX5 but worse.
Thanks for the colour compliment. Like and dislike are fairly evenly divided - not much in the middle.

We have a MkIV 1300 Spitfire here. It has a more or less internally standard engine with speeduino based injection on it and an overdrive gearbox. Currently it's all working reasonably well but the gearbox on particular is on borrowed time. When we built the car it was with a future engine swap in mind so it already has bigger brakes from a GT6 and rotoflex based CV joint rear end. Possible donors are under review. Not looking for megapower. Something around the 100bhp mark, light and compact. Plan A was a 1.6 Zetec SE and T9. The engine is cheap - the gearbox, no longer cheap or even very easy to find. Plan A2 was Zetec SE plus MX5 NA box. You can get kits to mate them. I even bought a box.... The box is on the big side..... not impossible but hard. Plan B may involve Suzuki parts. We have a gearbox from a Samurai which looks like a toy next to the Mazda one. It would fit in the available space and ratios are good. We have seen this mated with the G13BA Swift GTI engine - which looks like a very good prospect. Of course this is series 1/2 Swift stuff and old now. And not so easy to find in twin cam form. Lesser G series engines in 1.3 and 1.6 form are fairly common though it seems that the 1.6 is not a direct fit on the gearbox (adapter is cheap though). Seems that J series engines also fit the gearbox but they seem to start at 2L in the UK and are beyond what we are looking for (might be a bit much for the little box as well). Then there are the M series which are common and provide a range of choices in the right power/torque area. There are even some in N/S mounting (Jimny) but it is very unclear whether there is any chance of getting one to mate up to the Samurai gearbox without major effort. Using the Jimny 'box is undesirable as they have 1:1 5th gear whereas the samurai is 0.79 and suits the diff gearing much better. Any Suzuki experts know the answers? Thanks Nick The potential victim

11/10 for bravery and commitment.
I’ve welded some rusty cars in my time....... but I reckon I’d have run away from that!

A lot of Triumph wheels were made by Dunlop and are stamped with their logo as well as the Triumph part number.

Quad headlights are a major win in my book and well worth the (quite considerable IIRC) effort. Look way nicer and work way better. I always liked the Sprint wheels..... but great looking car whatever Nick

Another vote for the proper stuff and for LB Restoration.
The proper stuff is more than just flux as it tins the surface like magic when heated.
So easy even I could it. Keeping the lead on the car...... not so much!

Not sure why but I tried Demon Tweeks (tell a lie, I had a tab open..) and they came back with SUV tyres for a 215/70x15 but a Toyo CF2-S came up H rated but 98 load index and just under £60 a corner... I bought tyres from Demon Tweeks a couple of weeks ago. I knew what tyres I wanted and they came up cheapest. Way lower tha Camskill even where I got the last lot. Really rocked me . Never known Demon to be cheapest on anything before! Nick
