I know they say they fit the drive train and remove before shipping to US but in practice I don't believe they do. In all of the installs I have done there are no witness marks on any of the bolts on engine mounts or anything else. No marks on any of the painted parts. That being said, I wouldn't worry about it too much. I have not seen any problems yet with basic fitment. The main issues we have had recently are electrical. It is clear they never go power on with the cars and test anything electrical. There have been several miss-wired wiring harnesses that have been a bugger to troubleshoot. With the new sales model they can't really fit the engine in the car since they now have no information as to what engine you select or if you are even going to go through Mountune to get an engine. One may go an alternative route for a drive train in the new model. I am currently working on a 2.5L Duratec NA 10.5:1 and tuned to ~300hp with Haltec ECU. Should be a kick and way cheaper than a 620 engine at the new prices.

For years the drive trains have been supplied by Seven Motorsports, Caterham's spin off business to supply engines. Seven Motorsports is still making them and shipping to Mountune. I have been talking to Mountune about how this is going to work. Mountune orders a part number from Caterham and ships it to you. They don't plan to touch the engine. I have asked for a BOM of what comes with drive train but have not received an answer yet. Right now I don't know how to order an engine for a specific build as in how do I get wet or dry sump etc.

The new prices are supposed to include tariffs and shipping. They are meant to be an all inclusive MSRP as picked up at the dealer. I would try a different dealer.

Well Folks, In 2023 I ordered a 360R with the following options: SV chassis vented front brakes track day roll bar battery switch wheather package with aeroscreen carpet leather seats quick release momo painted nose band with stripe dry sump Not very extravagant and well within my budget and a car I could easily upgrade to 420R spec by just changing cams and a remap. When the dust settled and all paid it came in at $51640 including shipping. Now I did benefit from a very favorable exchange rate at the time but also took a hit on Covid shipping costs at $8300. I thought I would check what the same car and options would be in the new US price plan. Based on these options today's price would be $86238, a 67% increase. Even with tariffs this seems a little over the top. If I was looking today I doubt I would consider a 360R at that price. Also, in the new price sheets there was no dry sump option. It also is not listed in the R-pack standard equipment list. Are they not offering a dry sump or is everything dry sump? Need some clarification there. I don't think I would take one with a wet sump. Another question: As I understand the chassis MSRP includes shipping. Does the powertrain pricing include local shipping as well? It sure looks to me that this new pricing plan has some problems to iron out.

That is left over wiring for oil temp sensor. Black is ground. Brown ends up at the dash harness connector but is unused.

Yours was the only one from that batch that had gone out. You should have the replacement by now. Let us know how it goes.

2016 was when they changed the gauge. If yours is reading high there is a different issue. All the new ones read low- like empty at half a tank.

OK, Here you go. look where the tip of the screwdriver is. There is a little tab there that you can't really get with your finger. Push in on the tab with screwdriver and pull on connector. The tabs on the side look like locks but are only guides.

Just to verify, this is with the gauge removed, right? With the gauge installed there should be a voltage of about 3.1-3.2 volts on black/green wire. If it is, then this indicates something wrong. The 470 ohm should persist key on or off. Next step is to disconnect at rear of car and see what you have on that wire with both ends disconnected, should have no continuity to ground at all and no voltage, nothing, nada. Another step in trouble shooting can be to leave the the ohm meter connected, verify the resistance changes key on verses key off. Leave the key on and start pulling fuses until you see a change. Just for grins try this test while disconnecting the 2 wire plug on the back of the alternator. The connector in the back only has one lock, not 3 but it can be a pain getting in there to remove. I will go out to the shop and try and get a picture of where you press to unlock.

If you are getting 1.M ohms it is definitely not connected to the tank. Try this: Check voltage between Green/black and ground at gauge connector with the gauge disconnected. Try it with key off and on. Voltage should be zero in both cases. If you read voltage let me know what you get. The Green/Black wire goes from the gauge connector through a large connector up under the dash in about the middle. It then goes straight back to the tank sender. We had one where two of the pins were swapped on the connector in the middle of the dash. The mystery unit by the tank is a fuel pump controller and has nothing to do with the gauge. It is straight out of Ford Focus and can be used to control fuel pressure but Caterham does not use this feature and leaves it at a constant pressure. You can also check continuity between Green/Black at the gauge and Green/Black at the connector under the left rear of the car that goes up to the controller. You should have continuity(zero ohms) there.

Please send it back so we can check it out. The light should not come on.

The wire from the gauge to the sender is Green/Black one. Red/White is the light. Green- 12V, Black- Ground. the sender is just a potentiometer to ground. An ohm meter between Green/Black and ground will read about 70 ohms when empty and 460 ohms when full. We have seen wiring harnesses come from the factory with pins swapped. One had the Green/black tank sender wired to the alternator. @hyper7 if gauge correction unit isn't working please provide us with what it is doing. Or send it back and I will check it so we know if it is the unit or the car.

There is no coating on the cat. It comes just polished stainless like the pipes. The color is just normal heat coloration. Anything from the road that gets splashed on it while hot will remove the color like that. If you really want to remove it use a product for removing blue from chrome motorcycle pipes. Those products work just fine on stainless too. Mine look like crap after 900 miles in the rain.

For what it's worth, we talked to Caterham's chief engineer on this a while ago. They are just sending a fixed pwm signal to the pump controller from the ECU to run the pump. It does not use any pressure sensor or closed loop control. The fuel pump assembly is right out of a Ford Focus. Why they even used the controller is a mystery.

As @CBuff said, I work with Bruce, usually one day a week. Beachman Racing is alive and well. The race season this summer was quite hectic and I'm sure some things fell through the cracks. Yes, I am the one who designed the fuel gauge correction module and sell it through Beachman Racing. We also designed the replacement CSR rear suspension fittings that don't spontaneously fail. Bruce is a one man show as @Croc said except for Wednesdays when I show up to help. I am a retired guy who is helping Bruce mostly for entertainment. Since I see Bruce frequently I would be glad to relay questions. As to the G7 race cars, There is one left but it is not assembled at the moment and Bruce will only sell it to someone who will campaign it in the northwest race series since he wants to grow the field to make better racing. The G7 should be taken off the website but that is way down the priority list. We did just unload a brand new 420 SV factory built race car from the last container that will be for sale soon. Again, Bruce wants to sell that one to someone who will race it up here.
