I'm glad to hear it held up well. I couldn’t be more please with these gauges. Scott

No, sadly that is the cost per unit. However, you get rpm and speedo in both so if you can stand the style mismatch between your original gauge and the Motogadget gauge it would be fine... that was my original plan.... but I couldn't stand the mismatch.. Each instrument comes with a speed switch and magnets. One can be saved as a spare. On the speedometer the top digital display would be rpm and on the tach the top digital display would be speed. The lower display on each can show volts, time, oil pressure, and so on as you chose. My lower display is currently set up with volts on the tach and time on the speedo. You can set warning lights, for example if the voltage falls below 11.9, or whatever. As you can see from my videos, I do not have the tach signal going to the speedometer yet or the speed signal going to the tach. That's next on my list of things to do as well as wiring the high beam and the other warning lights to show on one of the instruments. Here are more details of the installation.... The reed speedo sensor is a simple magnet/proximity switch that sends a ground signal to the unit on each rotation of the wheel. A tiny rare earth magnet is glued to the rim. I made a mount for the switch out of aluminum and a clamp I found on Amazon https://www.amazon.com/dp/B09MLKKW3L?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 and used the fender stay as the mounting point. I measured my front wheel and worked out the diameter in mm's and input that into the gauge and got it very close to my GPS speed on the first try. On the tach, at least on my '99 tach plug, pin #3 is the tach signal wire and pin #6 is switched 12v and pin #5 is ground. Those plus constant 12v from the fuse box are the main taps one needs to make the motogadget tach work and can also go to the speedo for tach functionality. The ground signal from the speed/reed switch provides the speed signal to each instrument. I like that I could set the odometer to match the car's mileage. I haven't set up the shift light or gear indicator or most of the other functions yet. I bought a Motogadget breakout box and apart from speed and tach, that is what the other sensors would go into and then to the instrument through the orange LIN BUS wire. Rather than cutting wires in the dash I simply tapped the original wiring where needed and ran the constant 12v from the fuse box with a fuse tap. I added an 80mm o-ring between the bezel and the dash on each gauge to give the installation some depth to help match the larger bezels of the original instruments. https://www.amazon.com/dp/B00VFK535G?ref=ppx_yo2ov_dt_b_fed_asin_title Each gauge has three 3mm holes on the back so I cut 3mm threaded rod to length and used my 3d printed mounts and thumb nuts to secure each instrument. This is the threaded rod: https://www.amazon.com/dp/B0D22QGKHN?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 I can share the 3d mounts if anyone wants the STL files. 3mm thumb nuts here: https://www.amazon.com/dp/B0DCYK3B98/ref=sspa_dk_detail_1?psc=1&pd_rd_i=B0DCYK3B98&pd_rd_w=Un3M9&content-id=amzn1.sym.8c2f9165-8e93-42a1-8313-73d3809141a2&pf_rd_p=8c2f9165-8e93-42a1-8313-73d3809141a2&pf_rd_r=1QJ58083RXS84TH8TRMZ&pd_rd_wg=cAblT&pd_rd_r=cba31dc4-164b-43ee-9c55-3416a40837e5&s=industrial&sp_csd=d2lkZ2V0TmFtZT1zcF9kZXRhaWw I used the hole for the odometer reset for the switch to control the functions on the instruments. Each instrument comes with a small switch you can install. I decided to reduce that to one switch to control both. The hole had to be enlarged slightly. This is the switch I settled on: https://www.amazon.com/dp/B000HEKULI?ref=ppx_yo2ov_dt_b_fed_asin_title Clicking left controls the tach and clicking right controls the speedometer. The wiring for either gauge and the breakout box is below.

Finally have had time after the speedo and tach install to get out and enjoy the car. I love this thing.

I ended up going for Motogadget multifunction gauges for the tach and speedo. They are 80mm and a bit spendy, but I was aware of these products from my motorcycle hobby. I 3d printed mounts for them and wiring was fairly straightforward. So far, apart from tach and speedo, I have only wired in the turn signal blinker. I do like the voltmeter showing. The Speedometer is triggered by a sensor i ran to the front right wheel.

Did you ever figure out the process? Scott

I think it looks great! Scott

Good advice! I did autocross years ago and think I'll start out with some local events, that's probably all the speed I need at this point in my life! Scott

Dave's site about his upgrade options is very interesting and he clearly knows these engines. Having him rebuild one for shipping over with a few upgrades and the E6 ecu would be tempting and I think you could trust him to evaluate any engine he send over to you. Off topic, but have you considered a swap to a different engine, like a duratec? Scott

I looked a bit and found this: Importation of Vehicles Over 21 Years Old: EPA has long interpreted the equivalence requirement to mean that the engine must be identical to the engine that was originally installed. Such an engine is one that is the same model and configuration as the original engine. Importers wishing to utilize this provision are strongly encouraged to contact EPA's Imports Hotline prior to importation of such vehicles to ensure that the equivalency requirements are met. The Imports Hotline can be reached by email at imports@epa.gov or by calling 734-214-4100. Importers are encouraged to read the detailed information on the importation of nonconforming vehicles and engines, which can be found in the Procedures for Importing Vehicles and Engines into the United States (pdf) (3.2 MB, EPA-420-B-10-027, July 2010).

Sorry, I don't have a good answer on importing, but I'll follow this closely since I also have a VVC car. If you don't mind telling what happened to your engine and would it might not be easier and cheaper just to buy parts to have it fixed? There are many videos and articles online about these engines and all kind of work on them. Scott

That was an interesting article. Scott

Much appreciated!

Those are great points. I looked over the build sheet and it really doesn't go into detail about the sources of the parts. When you say steering bracket are you referring to the steering rack or something else? Scott

I ended up going with Hagerty with an agreed upon value for my 1999 Caterham. The application and underwriting process was painless.

LOL, I just spent thirty minutes figuring out oil filters for this motor. I hear you.

Thanks for the tip on the book and about plugging the hole. I'll be tinkering this weekend and will p0st some photos of the speedo. Scott

It's mechanical.

I did some soul searching and research before I bought it since these motors and parts are like hens teeth over here. It has the five speed. I've only driven it a couple of hours and I'm loving it!

Thank you all, I have my research cut out for me and appreciate the insights. Scott

LOL, sounds great! Scott

I've done a search and don't see anything recent. I've recently acquired a 99 Caterham with a history of failing speedometers. It appears that various drives and cables have been replaced over the last 25 years even though the car has not been driven that much. The speedometer has recently failed again and I'm not inclined to fix the problem the same way and am looking to replace it.. Is anyone aware of an 80mm GPS speedo that looks similar to the Caterham unit or an 80mm non-GPS one with a sensor I could run to one of the front wheels? I have found the Speedhut GPS units but those are 85mm and I'm not wanting to modify the dash. Thanks! Scott

I have been a fan of these cars for many years. I remember buying a book about them in the late 90's; however, the stars never aligned until this past weekend when I went to pick up my seven. It's a factory built De Dion K1.8 VVC and was imported to the US a couple of years ago. I was lucky enough to get with it the records going all the way back to the order sheet, factory build sheet and every record to present. It has the lowered floor for the driver and the only additional options it had from the factory were the Ford Pacifica Blue pearlescent paint and carbon fiber dash. I'm sure now I'll be posting quite a bit as I start figuring things out. The only thing I know that needs attention at this point is the speedometer, which was working until recently. I notice in its history that this is at least the second time it has had speedometer issues. Scott

Very nice Bob!

Very nice! Scott
