Instant Performance Upgrade | Land Rover Defender 300 Tdi Boost Pin
Вставка
- Опубліковано 4 жов 2024
- A very quick and inexpensive performance upgrade for the beloved 300tdi engine from Land Rover is to swap out the standard boost pin in the fuel injector pump and replace it with an upgraded boost pin from Fourbys.co.uk:
fourby.co.uk/e...
It's simple job and I hope this video helps if there's any doubt about your capabilities of potentially doing it yourself.
It's worth doing the full tuning package from Fourbys as it's very inexpensive for the value it ads to your driving experience.

Discovery 1. 1996. 300 TDI. I rotated the original boost pin 180 degrees and rotated the toothed wheel 1.75 turns clockwise and that worked great More torque and no smoke. Smoke is bad
Very interesting! Forgive my ignorance but what toothed wheel? Mine does smoke now so you’ve got me wondering if I’ve got it wrong.
@@DaleReubin When you take the pin and diaphragm out, you will see there is a spring sitting on a toothed wheel (commonly called the starwheel). By moving the starwheel up or down the thread you can alter the preload on the spring. More preload = less smoke. Different folk have different tuning strategies, some like more preload, some like less, some like more max fuel screw, some like less. Search for VE pump tuning you'll find tutorials.
this is such a great vlog. totally genuine. Loved the "found it" with the wiring.
i put one of these babys in last week - now I am blowing black smoke like a wounded WWI fighter
HAHA! Oh no... Any idea what's causing that?
@@DaleReubin pump has probably been turned up prior to the boost pin being fitted meaning that it has loads of extra fuel - all the boost pin really does is increase the fuelling and change the delivery curve so if the pump has had its fuel turned up alrady you get way too much fuel
Cracking honest vlog and thanks again for sharing buddy!
Enjoying the upgrades you are doing bro. Worst case scenario is you get a much better understanding of the workings of the engine.
Thanks bro! There’s so much that needs doing. I am enjoying to process of learning the engine though!
Just unbolt the aircon compressor and leave the pipes connected and move it upwards and tie it up, gives you the room you need, take off any support clips on the aircon hoses to increase the movement, no need to drain the aircon gas
Thank you! That's super helpful.
All the Fourby gear come with a QR code on the packaging. That will take you to the fitting instructions online.
@@andywilson1117 oh my goodness!! I wish I knew! Thank you!
Great video:) keep them coming!
Thank you 🙏 there’s plenty more on the way.
Really helpful, thanks mate 👍
Glad it helped
Nice work
Thank you, it's made a big difference.
@@DaleReubin waiting for part two
Can you plz do an update to this and let us know if your fuel economy has gone down after installing the upgraded boost pin
Thank you for the idea, I will do that in the very near future!
Nice upgrade!
How did it affected the fuel usage?
I honestly haven’t noticed a difference at all. I still need to fit the boost ring. Maybe that’ll cause more fuel usage. Not sure.
hello there from POrtugal .... what about smoke ?
Cheers !
Hello there!! There is a little more smoke but nothing outrageous.
Cool video. I've wondered about this for a long time. Are these available in SA? I'd be very interested in the difference in your fuel economy...
TA
Good point. I’ll fill it up and do a fuel economy test
Don’t bother …. Uses loads of fuel and exhaust manifold gets red hot
If you want to go faster buy a faster vehicle
Don’t compromise the reliability of the Landrover buy ringing it’s neck…….
I don't think Land Rovers are known for reliability. But anything to help give it a little more pep is welcome.
Was the speed you were talking about on the video in MPH or KMPH?
KPH. No way he's doing 80MPH on a city street
how is the fuel consumption after this upgrade?
I can't say I've noticed it getting any worse but I need to do a test and report back.
Hi. What size is the hose going from the turbo to the diagpharm?
Did you already have the pin rotated before you did this?
No, but when I took it out I did notice that it could be and questioned why I got the boost pin...
@@DaleReubin whoops :)
