Fuel Injected Triumph Stag Conversion Update

Posted on March 18, 2013 by admin

Progress is steady on the Stag Fuel Injection Conversion. All the sensors are in place. Some time Friday was spent dialing in the Throttle Position Sensor with the laptop and included software. Chip and Dean had to do some slight adjustment on the throttle butterflies to make sure they were synchronized. Start up should be real soon.

Green Triumph TR6 Update

Posted on March 16, 2013 by admin

Allow me to report in on the Green TR6. Follow along with the pictures below…

Once again, the patient.

Toyota Caliper mounted with new rotor and stainless brake line.

Picture of the TR6 Differential Mount after Chip has welded in metal to box it in and make it stronger. This will guard against the rear differential mount crack.

Differential has new bushings on it and a new front seal (not visible).

Rebuilt TR6 Distributor from Advanced Distributors.

Rebuilt Carbs from Gary Martin.

We have just a few odds and ends to finish up and this car should be ready to go.

Green Triumph TR6 Improvements – Including a Picture of the TR6 Differential Mounts

Posted on March 8, 2013 by admin

Back on March 1, 2013, we introduced this Green TR6, and it’s time for an update. This car is getting Toyota calipers to replace the stock front calipers, and new rotors as well. New coolant hoses will go in, and tube shocks are replacing the original lever shocks. The exhaust needs some repair, and the differential is leaking, which gives me a great opportunity to show the TR6 differential mounts that result in many inquiries because of their propensity to crack. Alas, pictures seem to communicate the changes better than words, so peruse the pictures below for an idea on the progress.

New Sway Bar Links.

Here, I was trying to show all the differential oil that has leaked out and sprayed the underside of the car. The differential pinion seal is leaking in this car.

Photo of the four differential mounts while the differential is removed. The ones in the top portion of the photograph are towards the rear of the car. The lower ones are towards the front of the car. The front mount on the passenger’s side (the American passenger’s side, that is) of the car is generally the one that goes first. The cracks can be either visible on the bottom radiating out from the center or on top next to the body where they are hard to see. To be clear, these are not cracked… just showing what the mounts look like.

We are replacing the old lever shocks with tube shocks. This brace is part of that package. It’s not finished, as Chip will weld in another brace to guard against fore/aft stresses.

The car will get all new coolant hoses and clamps.

Customer mentioned a rattle or sound from the exhaust. When Chip removed the exhaust, the tube on the left simply fell off.

The “stumble” previously mentioned (in the first post on this car) should respond to a distributor rebuild (by Advanced Distributors) and the carb work that Gary Martin is doing for us. Should any of these repairs or modifications spark a question, contact us and we’ll give you as much information as we can. Thanks for visiting.

More on the Yellow TR6

Posted on March 8, 2013 by admin

Odds and Ends continue on the Yellow TR6. It’s almost ready to go. Someone had wired the reverse lights to the overdrive switch, so that if you wanted the reverse lights to come on, you had to flip the overdrive switch. Odd. Chip put the wiring back as it was supposed to be and below is a shot of the switch on the transmission.

This was mounted backwards. We turned it around.

The chin spoiler was mounted backwards. Chip turned it around.

We installed some new grommets on the firewall.

Some of the old hoses were more like pipes. The clamps had to be sawed off.

Green TR6 Maintenance

Posted on March 1, 2013 by admin

A couple of months ago, I accusingly told Chip we needed to rename the place “Red TR4A Motorsports”. I guess now we should rename it “TR6 Motorsports”, because the shop and parking lot are full of ’em. These things come in cycles, I suppose.

This fine TR6 comes to us in a green color good for an extra 2 mph in top speed or 1 mpg in fuel mileage depending on your driving or drinking (separately) habits. Fine as it is, it occasionally needs attention. Here at UK Motorsports, we pay attention. According to the owner, the troubles are:
–stumbles a bit below 2000 rpms (ignition, carburetion, both?)
–check valve clearances, cylinder pressures, head torque
–oil and filter
–vibration in the dash

Chip will also give it the once over to check for other common TR6 maladies and make recommendations from there. This one is in very nice shape already… (see below)

Well Preserved TR6

The Dead Mouse Yellow TR6 Update

Posted on February 25, 2013 by admin

After removing the dead mouse (see this post), Chip started in on the list of repair items. The brake lights, turns signals, and fuel and oil pressure guages do not work (or did not work, Chip’s already gotten to the bottom of most of this). The owner also had a wood dash he had already purchased that he wanted us to install, so Chip has done that. The top dash pad and lower kick pads have been replaced as well. We’re (by we, I mean Chip while I watch and grunt like I understand what he’s doing) also replacing the bonnet release cable. Let’s take a look…

The windshield (and hardtop, not pictured) are off the car.

The new dash and dash pad are installed. Chip’s trying to get his hands out of the way.

See the shiny metal piece? It was a piece someone tried to use in the past, but it really didn’t fit. Chip replaced it with the correct part.

The windshield is back on since I’ve been there, so I’ll have updated pictures soon.

Fuel Injected Triumph Stag Update

Posted on February 20, 2013 by admin

Let’s take a look at the progress on the Stag. If you’re just tuning in, we’re installing a Throttle Body Injection Kit from Patton Machine. Dean has already dealt with a malfunctioning window switch and a rusted windshield wiper motor (see this post). Next, the water pump was leaking, which necessitates removing the intake manifold. (Click any picture to expand.)

Intake Manifold Removed for Access to Water Pump

Once the water pump was sorted, we began installing the parts for the fuel injection conversion. The photo below is a shot of one of the sensors. This particular sensor measures coolant temperature. Additional photos below illustrate the Fuel Pressure Regulator, the new fuel line to the engine, the new return line back to the tank, and the fuel pump mounted underneath the car. Scroll down to take a look and read more details.

Here are the adapter plates (with injectors) attached to the carbs. In this picture they are on the workbench.

New dual gauge that registers water temp and oil pressure.

We’re in the trunk for this picture. Both of these lines are new and bent by Dean. The line with the filter on it is the outbound line and the other line is the return line back to the tank.

Another angle of the fuel return line.

The computer is mounted to the firewall in the passenger’s side footwell.

The fuel pump mounted underneath the car.

Gratuitous shot of Dean’s fuel-line bending handiwork.

Here is the wiring harness that comes with the Fuel Injection Kit. We are going to modify the harness so that it fits better in the car. It’s a bit lengthy as it comes and we think we can make the installation a bit more tidy. Patton doesn’t do a Stag specific kit, so we’re adapting this one to work.

Triumph TR6 With Toyota Five Speed Conversion

Posted on February 20, 2013 by admin

We have the Toyota five speed installed in a customer’s car (TR6), so I wanted to show you some pictures of what it looks like.

Looks like it belongs, doesn’t it?

Triumph TR6 Pest Control

Posted on February 16, 2013 by admin

We do a good percentage of “This hasn’t run in a while, please make it work again” service around here. While we’re trained professionals, it can be grim work sometimes. Here are some pictures from a recent TR6.

Just some wiring, right?

Another Red Triumph TR4A In For Sorting

Posted on January 28, 2013 by admin

I’m not sure I’ve seen a TR4A in the last six months that wasn’t red. This car needed a new wiring harness, dash pad, and various odds and ends. One of those odds and ends is that the seats were installed improperly (in the wrong position) so the seatbacks were rubbing against the top frame and causing wear. Another little detail is that the windshield was not adjusted when it was installed (the angle is slightly adjustable), so the windows didn’t fit flush with the windshield surround. Some pictures…

New dashpad installed.

New Voltmeter installed as well.
