Lucas Fuel Injection Conversion Kit | Jaguar E-Type 4.2 Upgrade

[@jeffharrison5265]

A DIY video that doesn't show any of the equipment. Weird. Looking forward to seeing and hearing more about it. Would be great if it works on my 72 XJ6 as well.

[@SNGBarratt]

Hi, and you make a good point, we'll do another video of the contents of the Kit.

[@HoldenVintageandClassic]

Great video guys!

[@scottthomas5999]

Nice job. Very cool!!!

[@paulsnook5408]

Very nice fuel injection system But what we want to see it is on the rolling road dyno a before and after testing bhp & torque and is it more fuel efficient ??

[@SNGBarratt]

The point is that you can set up the system to your requirement, so we have set ours for reasonable economy and smooth power delivery with plenty of torque.

[@jameseastwood4984]

In fairness they would need to run the car on the road for a number of days to optimise the self learning. So you could have a dyno test with the SUs then later a second session with the EFI. I would expect the power/torque gains to be in the order of 1-4%, therefore diffecult to clearly identify with dyno sessions on different days.

[@Looney2021]

I’ve just had a Jenvey system installed with heritage throttle bodies (45 dcoe appearance), the injection won’t add much at all to the bhp but it will allow a high lift cam and not upset the idle, even though the kit is about 12k + 8/900 on a decent rolling rd, it’s a lot of work for not a lot of gain.. std engines keep your SU carbs, want a sporty engine then yes great.. mines modified makes 260 at wheels 300lb.. but drives smooth with the injection .. hope that helps

[@spyroscharalambidis7907]

Shouldn't the kit have an air filter?

[@salamander5703]

Single sensor for spark timing but no sensor to detect whether it should be firing no. 1 or 6. Does it fire in pairs 1&6, 2&5, 3&4 and "waste" the spark in the non firing cylinder?

[@SNGBarratt]

Hi Yes, it has a wasted spark, firing in pairs, without a cam sensor.

[@TheFluffyOctopi]

🎉 top job

[@rickveley5326]

So, a couple of questions - Is the fuel pump pretty much silent being in the fuel tank? Is there no airbox or air filter? Finally, it would be great to see data in the same car with the original SU HD8's vs the Lucas fuel injection. Thanks for the video!

[@SNGBarratt]

Hi The pump is very quiet. On start up you hear it working for a moment, and when it's at pressure, it's silent. The great thing about mapping the ECU, is that you choose what you want. We opted for smooth power delivery, What was a power curve is now a straight line.

[@AidanHill-s7c]

Can I get one for my 76 XJC? Cost?

[@robgillam340]

This looks like a well-made and designed product. I'm torn on the idea of modernising classic cars. While you can update them with electric motors and the latest technology, I feel they should be preserved in their original design. A part of the e-type experience is the unique throttle response of the SU carburetors and the process of starting with a choke. Along with mopping the dips of oil from the garage floor 🙂

[@SNGBarratt]

Hi Rob, Thanks for looking at the kit and your observations. We totally respect the wish for some owners to have a truly original car, and this kit is clearly not for them. However there are owners who want some of the modern comforts, like power steering, and 5 speed gearboxes, modern cooling fans now needed on todays busy roads. We are developing this kit to be able to run the fans and electric water pump from the ECU controller. We also have customers fitting this fuel injection to a D type, and an XK120 (fitted with a straight port head). Another is being fitted to a series 2 car and we have a prototype fitting for the front water intake to clear tighter fitting bonnets on some of these cars. We have been running our car now for well over a year on this system, so it's well tested. Please email us for further information.

[@robgillam340]

​@@SNGBarratt You guys do a great job keeping parts available for classic Jags. Please don't take my comments as negative in any way; I think I'm what's termed a rivet counter😂

[@Rod990ktm]

It’s a neat idea, it seems it’s simple to install and well made. I’m pretty sure it will be an excellent upgrade. As a reference some years ago I upgraded to 123 distributor and was amazing upgrade on engine…. This will be impressive. BUT…… no way I am paying $15,000 dollars for the is upgrade. $6500, up to $8500 maybe.

[@SNGBarratt]

This won't be something for everyone, and quality comes at a cost. Thanks for taking a look.

[@Millmiglia001]

Can I get this for MY 1975 XJ6 C?.

[@barrykenderson8668]

Will bolt on to the cylinder head, but the rest will depend on space. Also need to change the in tank fuel pump in kit and sort out linkages and other sundry bits etc.

[@Millmiglia001]

@@barrykenderson8668Barry, thanks for getting back. Do you have the price for this item for an xj6.

[@barrykenderson8668]

Sorry Kamil I don't work at barratts. Hopefully somebody will reply back to you.

[@SNGBarratt]

Hi We haven't looked at this for the XJ6, but if you are interested, please email.

[@lp76100]

will this fit on a series 2 xj6 4.2 litre ?

[@SNGBarratt]

It should fit a LHD car, but some of the brake servo parts might be in the way on a RHD car. Fuel pump and wiring will also all be wrong as well.

[@robbierobson3251]

No air filters???

[@SNGBarratt]

We are developing a clip on unit with foam filter cover which allows the air intake trumpets to remain fitted. This unit will also be Lucas branded, available in about a month.

[@aranyarajkishoresingh3162]

will this kit fit an MK10 420g?

[@SNGBarratt]

The injection side will fit any straight port head. So fine for the Mk.10, but for cars which originally had twin carburettors, but with a straight port head, need to have the 2 brass plugs removed for the water to flow correctly. The wiring on our kit is designed to have the ECU fitted in the top of the passenger foot well of an E-Type, so in other application might need to be lengthened. The throttle control is designed for the E-Type, and would need to be modified by the fitter to your MK10. Hope this helps, but please email for further details.

[@Andersdenkende]

3.8 dual su?

[@barrykenderson8668]

I don't think so. SNG's XKE looks like a 4.2. Straight port head engines only.

[@SNGBarratt]

You will need a straight port head to fit.

[@lp76100]

cant hear it idle....

[@JP-Lucas-Girling]

Sorry you can't hear the idle sound, but it is quiet. If you check out the "Lucas Classic at Shelsley Walsh" KZbin videos posted by SNGB and others, you can see the car running at speed up the hill on fully synthetic fuel.

[@SNGBarratt]

We will do another video of the car running.

[@davidlangley2129]

Did the original manifold complete with SUs fall off the back of the cabinet when it was placed there? The video cuts off abruptly at 1m20s as it is tipping over.... Hope not...

[@JP-Lucas-Girling]

Hi, fortunately the carbs are fine. We send the kit out in a large wooden box with a hinged lid. The idea is that the box is big enough to fit all the removed parts.

[@jameseastwood4984]

@@JP-Lucas-Girling That's a great idea, as people will want to keep the old gears for originality. Very neat.

[@roefamily]

Educated..are taught to never us an acronym or abbreviation without first defining it...shame !!

[@barrykenderson8668]

Which acronym? Not TDC I hope.

[@SNGBarratt]

@@barrykenderson8668 Perhaps ECU?

[@barrykenderson8668]

I'm sure every car enthusiast with the most basic of mechanical knowledge knows what an ECU or TDC stand for. Another great video from Mr Stant.

[@SNGBarratt]

@@barrykenderson8668 Thanks Barry!

[@metalman4141]

Just more added problems

[@JP-Lucas-Girling]

It takes away all the problems of worn carburettors and ignition timing, but the ECU mapping requires a different skill set. The unit has open source soft wear, and is understood by tuning specialists. Once set, is stays set.

[@stephenyoung7267]

It's ok that you don't know anything about cars, but someone could install it for you for a price- and then you'll have fewer problems if you ever get an E-Type.

[@mcashnv]

Lucas? No thank you.

[@SNGBarratt]

I think this is a pretty good track record :- 1962 BRM, 1963 and 1965 Lotus, 1966 and 1967 Brabham, 1968 Lotus, 1969 Matra, 1970 and 1972 Lotus, 1971 and 1973 Tyrell Formula one world championship winners all fitted with Lucas fuel injection.
