Triumph TR5: Buying guide and review (1967-1969)

Triumph TR5 Triumph TR5
Forget the price – is the Triumph TR5 one of the best sports cars of the 1960s, bar none? There’s certainly a lot in its favour. It’s compact, handsome, and has independent rear suspension for good roadholding. Most important of all, it has a sweet and powerful (150bhp) fuel-injected straight-six engine.
Of all the Triumph TRs, the TR5 is possibly the most sought after, the most valuable and certainly the rarest, thanks to a production run of little more than a year. Effectively a stop-gap model created to bridge the gap between the four-cylinder TR4A and the six-pot TR6, the TR5 blends the more period looks of the older model with the smooth straight-six of the later one – which is why it’s arguably the best TR that Triumph ever made.
Strictly a two-seater, the TR5 looks great, there’s brilliant club and specialist support, plus it comes with a decent boot, so it ticks all of the sensible boxes. But it also sounds fabulous, is plenty quick enough, is easy to upgrade and maintain and it’s a hoot to drive. So as sensible sportscars go, the TR5 is right up there. Perhaps the only fly in the ointment is the high purchase cost of a decent TR5; for the same money you can buy all sorts of other classics that may seem even more appealing. Who are we to say you should opt for the TR5 over all of those alternatives? But if you do take the TR route, we’re pretty sure you won’t regret it.
Which one to buy?
There aren’t many choices to make when buying a TR5 as they were basically all built to the same spec. Overdrive wasn’t fitted as standard though, so go for a car that has it if you can. It’s possible to fit overdrive retrospectively, but costs are higher than you might expect, so haggle accordingly if this isn’t already fitted. 
Sadly, American customers were never offered the fuel-injected cars and instead made do with the carburettored TR250 version of the TR5. However, the US-spec cars were made in far greater numbers and have at least proved a useful source of rust-free donor shells to restore rotten home-market cars. They crop up in the UK relatively frequently, and you’ll pay less than for an equivalent TR5 as the steering wheel is on the left – unless it’s been converted of course.
Be wary of temptingly cheap US imports though. The carburettored engine is not only less powerful, rear axle ratios were lower to compensate and overdrive was a rarer option. On this note, converted cars tend to be worth a bit less than a TR5 originally sold with right-hand drive. Projects are very scarce but minters aren’t hard to find as the TR5’s high value and a good supply of new reproduction parts means really good restorations can make financial sense. If the bodyshell on an import is really good, it might be worth buying as a basis for upgrading the car to UK-spec
Before buying, make sure that you’re acquiring a genuine TR5. Because TR5s are worth more than TR4s and TR4As, it's not unknown for a six-pot engine to be dropped into a TR4 and passed off as a TR5. A TR5 chassis number will start CP, while CT means it's a TR4, CTC is a TR4A and if it's a TR250 it'll start with CD. All these cars have a commission plate, which is located on the nearside front inner wheelarch.

Common problems
• The separate chassis can rot in numerous places, with proper repairs often only possible by removing the bodyshell. Key rot areas include the diff mounting brackets, centre section (check for bulging) and where the rear suspension bolts to the chassis.

• Also look for poorly repaired accident damage, particularly around the front suspension turrets, the wishbone mounting brackets, outriggers and steering rack mountings.

• Corrosion is likely in the body panels, including doors, wings, sills and floorpans. See if the drain holes in the sills are blocked; if they are, expecting rusting from the inside out.

• The doors and wings corrode top and bottom; up front check the inner wings as well as the outer. Also look at the battery tray and scrutinise the door gaps. If they open up at the top the chassis is weakened through corrosion, or the car hasn't been braced during sill replacement. The B-posts and door tops tend to rust also.

• Make sure the beading is in place in the seams between the top of the rear wings and the deck; filler is sometimes substituted during a restoration. Finish by checking the footwells; panels are often stuck on over the old, rusty metal.

• The six-cylinder engine can suffer from excessive crankshaft end float, so push and pull on the bottom pulley or press and release the clutch. More than 0.015" movement means the crankshaft thrust washers have worn. If there’s a clonk as the crank moves the thrust washers have probably dropped out, irreparably damaging the engine.

• The Lucas mechanical fuel injection is often set up incorrectly, but with the right expertise it works fine. Problems are often caused by debris being sucked from the bottom of the tank if the car has run low on fuel.

• The four-speed gearbox wears after 100,000 miles, so listen for grumbling and see if it jumps out of gear. Rebuilt gearboxes are available from stock.

• Baulking when changing gear can be down to the clutch hydraulics not being bled properly. Sometimes the slave cylinder is fitted upside-down, so the bleed nipple faces the wrong way (upwards).

• The propshaft and driveshaft universal joints wear, so listen for clonks. They’re not hard or costly to replace though. Wear in the driveshaft splines is more expensive; upgraded replacements are available, which are more durable.

• The front trunnions seize if they’re not lubricated properly. This then puts a strain on the suspension, mainly the drop link on the wishbone.

• All interior trim is available on a repro basis and everything can be bought to fix any electrical issues. But be wary if the windscreen wipers don’t work properly. Motors can be easily replaced but replacing a tired rack entails removing the dashboard for access.
Model history
1967: The TR5 supersedes the TR4A, with a fuel-injected straight-six. Externally it’s barely discernible from its predecessor, but the new engine turns the TR into a genuine performance car. North American cars have twin carburettors and are badged TR250.
1969: The TR6 replaces the TR5; the new car is effectively little more than a reskinned version of the old car.

Summary and prices
If you’re looking at buying a top condition UK-original TR5, then you could potentially spend up to £45,000 on the perfect car. Decent runners can be picked up for £25,000-£35,000 though, while projects are £15,000 upwards.
Thanks to the considerably higher numbers built, the US-market twin-carb TR250 can be brought for around 20 per cent less, representing great value. Many have been upgraded with later fuel injected engines and converted to right hand drive too, which makes them perhaps the most appealing in terms of value for money.
If you want the ultimate Triumph, the TR5 is a no-brainer. It has those pretty Michelotti ’60s looks and was better made than the later TR6. The engine was properly balanced and had a cross-drilled crank, whereas the TR6 was slightly cheapened in assembly. Buy now, and enjoy!

    1968 Triumph TR250, Nut and bolt restoration to Tr5 specification, registration number FND 620F, chassis number CD2591L, engine number CC3772-E, Signal red. With less than 400 miles since a full nut and bolt restoration, this Triumph TR250 is one of 8400 leaving the production line in a very short production run of only 15 months between 1967 and 1968. Intended for the North American market they did not feature the TR5's fuel injection system but relied on twin Zenith or Stromberg carburettors which in turn endowed the engine to develop 111 bhp against 150 bhp of the TR5's injected engine. This particular example that we have the pleasure in offering for sale has undergone a complete nut and bolt restoration by its previous engineer owner over a four year period. There is a CD containing over 100 images of all stages of the work that has been undertaken, supported by two large ring binders containing receipts and invoices. Now in Signal red with a contrasting black interior, hood and tonneau cover, the TR was converted to right hand drive and fitted with petrol injection which technically brings the car up to TR5 specification. It is interesting to note that the car is registered as a TR5 on the V5C as DVLA did not recognise the TR250 as a model when the Triumph was registered for the road. During the restoration the following works were carried out, a full bare shell rebuild and repaint, the engine was totally rebuilt with new pistons, bearings, crank regrind and rebore, the cylinder head was converted to cope with unleaded fuel, new electronic ignition, new fuel meter and pumps, new injectors, high torque starter motor, new hood, new hood cover, new dashboard (burr walnut), new wood rim steering wheel, new Mini Lite style alloy wheels with Yokohama tyres, new suspension with polybushes throughout, new exhaust system, new break callipers, disc pads, new brake and master cylinders, new brake servo, new heater matrix, new three piece clutch, the differential was overhauled, the gearbox and overdrive unit were overhauled, and the list of newly replaced or refurbished parts goes on and on to a total in excess of £15,000 not including labour. The Triumph currently has a road rally look with its Mini Lite wheels and bumperless body work but both the front and rear bumper and original steel wheels will be included in the sale and they are also in good condition. In summary the car drives exceptionally well and sounds lovely. V5C, MOT to November 2016, tax exempt
