Land Rover 300 TDi Tuning - Boost Pin - Boost Ring - EGT Gauge- Alisport Intercooler - Fourby UK

Follow us on Instagram! / donegaloverlanding With our Discovery now at 3 ton in weight with all of the heavy duty upgrades and the overlanding gear, it was time she was brought in for some tuning to bring some life back into the 300TDi lump. We ordered the full selection for the full bhuna performance gains. We also installed a full width Alisport intercooler at the same time.
This video is not intended to be an "how to" guide. Many steps are missing. This is to show you the relative ease of install and more importantly what it is like to live with after having plenty of time to make an assessment of the changes. There are many detailed guides online and on the fourby uk youtube channel to give you a more in-depth guide.

I planned to skip through your 'long, boring' drive, but found it really fascinating.

[@DonegalOverlanding]

Thanks Keith, glad you got some use out of it. I knew it would be quite boring, but then thought if I was in the market to buy them then I would hope to actually be able to see what was going on, rather than just read positive comments on facebook.

[@jessehunnisett2402]

This is the video I needed, thank you so much!!!

[@andicog]

Did the same on my 300tdi defender, absolutely transformed it, I have stock turbo and intercooler but disco transfer box, it's stronger right through but I love the power at around 40mph in fourth, just boot it, turbo spools up and your off! My egt is lower than yours but I adjusted the star wheel by half a turn to cut smoke slightly, it will still leave nice smoke if the throttle is mashed in lower gears. Best bang per buck I've ever seen on any engine I've ever owned!!

[@Merc-Rover]

Very clear and concise video. Thank you!!!

[@scaryfakevirus]

I may be wrong here but if the spacer ring is put in and then washers are palced under the springs surely you are just raising the whole spring to what it was before more o less? Why not leave the washers out and just have a thinner ring?

[@overnighter]

Love the video... I also need that EGT probe and gauge for my 300 tdi (Defender)

[@kylendonovan9470]

instablaster.

[@DonegalOverlanding]

It was not really that accurate. Better of to get the madman system. We scrapped the Fourby stuff as it was reading way too high rendering it useless.

[@tsparc2]

Hi - Defender 300tdi owners here - how does it handle on the motorway? It looks like it was pretty easy to get the temp to 700 which worries me a little

[@whitacrebespoke]

Did you ever get an answer? Just rebuilt my defender and it’s not staying with out upgrades as it’s so slow. My 02plate TD4 freelander pulls the same trailer better with same amount of tools in it. I don’t want to find I’m cooking head though if I modify it as I have to tow on motorway fair bit

[@josephclarke2094]

Thank you for posting this video! It is most helpful, now it has been some time since you did all of the upgrades has there been any issues caused by the modifications?

[@DonegalOverlanding]

The vehicle was taken off the road in August 2019 because we are turning it into the world's first Discovery 130. You can see some videos of the progress o our channel and lots of info on our facebook page/group. We had no problems at all to date though and would do it all again.

[@marco_zero-4x4]

Just curious about your EGTs, they seem to be very high, I've got a 110 heavily loaded with pin, ring and the controller and I actually have a hard time to get it to even 600, I run the fourby guage as well.

[@Pepperdew96]

This 300 is SERIOUSLY over-tuned. Watch the factory water temp gauge. It moves above half way! Mine only does that when it is about to commit holy suzuki, and I know about it long before because the AC fans start screaming at 100C (at which point the gauge is still NOT quite half way). Maybe he is getting away with it due to the cold climate, but here in South Africa that would have been at LEAST one head gasket during the course of this video. Why would you risk your engine for an extra 20km/h? A mildly tuned 300 is more than capable of doing everything a land rover was designed to do. 300tdi land rovers are designed to do many things. Drag racing is not one of these things.

[@DonegalOverlanding]

@@Pepperdew96 this is exactly where the water temp gauge went to before the tune, and its exactly where it is meant to be. On our trip to the Pyrenees, it was about 34c in the shade and we were driving up and down mountains and it never moved once, always was in the exact same place. This tune was after that and the temp is identical.

[@DonegalOverlanding]

The fuelling is a bit high, it couldve done with being turned down a little. It had not been adjusted in this video.

[@liambird5349]

Do you fit boost gauge before of after controller thanks

[@orangutanfan3179]

I'm surprised how high your EGTs go, what size exhaust do you have?

[@DonegalOverlanding]

standard at that point.

[@PATRICKCARROLL1963]

Great video

[@rjl110919581]

THANK YOU FOR DETAIL VIDEO ON YOUR DISCOVERY

[@DonegalOverlanding]

You're welcome. Thank you for subbing and supporting the channel. Appreciate it.

[@willcowell8197]

Did the egt gauge give you any issues with the initial wiring? I'm fitting one exactly the same from fourby but keep getting a p100 showing on the gauge..any ideas?

[@DonegalOverlanding]

Had no problems at all. Was straight forward. I think I remember someone speaking to Neil Ensor about a code when he installed it. Check out the Land Rover TDi Performance group on facebook, the answer will hopefully be in there. Neil is on holiday himself right now, but there are plenty who could guide you.

[@hondata05]

Where are you getting the power from for the gauge?

[@DonegalOverlanding]

We took it from a random switched live on the fuse board that's located near to the drivers door.

[@DaanvanGruisen]

Wow, that EGT seems a bit high! I am running a standard Defender 300TDi with 285/75/16R tires. At constant 63 mph on the flat Dutch highways, my EGT reaches about 400C, at 75 mph it shows about 500C. Now i bought a cheap Chinese EGT so not to sure about its accuracy. I also noticed that now the cooler autumn outside temperatures have quite in impact on the EGT. Any thoughts on this!? At 62mph my fuel consumption is about 25mpg, at 75mph I get 20mpg. When driving 75mph, some dark haze starts coming out of the exhaust, which I don't like. How do any of the mods (intercooler, boost pin/ring) impact the exhaust fumes at higher speed?

[@ouisi7]

That sounds accurate. Normal range is between 250 and 680 depending on load. Max is 720c. And by max, I mean you are doing permanent damage to the head at that temp. Most people that have upgraded their intercooler say it was a waste of money. Very little benefit overall. The boost pin will cause higher EGT. The ring is just to prevent excessive smoke.

[@jmileshc]

What egt are you getting on sustained acceleration or overtaking AND fixed high speed 70mph, long gradients etc. on A roads & motorways please? Really great idea to let the flush of the new ebb away.

[@DonegalOverlanding]

In general driving about 60mph on flat its around 450-500c. Uphill it soon climbs if I try to maintain the same speed. If I was on the flat at 70mph Id be around 520c. Im never on motorways, there are none anywhere near me. Though I will be on one tomorrow so if i remember I will check and post again.

[@DonegalOverlanding]

I was on the motorway today. So at 70mph which is a lot given the aerodynamic disaster that is my vehicle these days, it was about 620-680 depending on tiny inclines in the road. I normally sit at 60mph most of the time as its easier.

[@raymondlogister6828]

great video. thank you for posting. Do they also have a temperature gauge for the discovery 2?

[@DonegalOverlanding]

I believe the one we have also fits a D2. Best bet is to check out the fourby uk facebook page. Just ask them the question. I'd hate for you to order it and it not be suitable.

[@DonegalOverlanding]

They do now sell one for the Discovery 2.

[@motoninja2747]

Can you do just the boost pin and ring or do you need the exhaust gauge as well?

[@DonegalOverlanding]

You do not need the gauge. Probably the majority of people do not have the gauge. However I seriously recommend it because it is VERY VERY easy to get to 700c when you are climbing up even a shallow hill and you have your foot down. Im sure I would have destroyed the engine already were it not for the gauge as Id never have believed how easy it is to overheat it.

[@motoninja2747]

Donegal Overlanding ok well did I miss where you said I can get this stuff ? eBay I would be after a green gauge I think

[@Latindanceindia]

Do they similar stuff for a Isuzu trooper 3.1 engines ?

[@DonegalOverlanding]

I do not think so, they are Land Rover specialists. However it would be worth sending them an email to see if they can. Fourby.co.uk

[@Latindanceindia]

Can i use the exhaust gas temperature gauge in any engine ?

[@Latindanceindia]

I have a Isuzu 3.1 lt in my series 3 ..

[@dickyboyjr]

Yes. Just not the fitting kit.

[@tanjaherrmann2422]

How much Hp/Torque has it now?

[@DonegalOverlanding]

No idea as we never had it tested. Right now its going to be even better as we have completely changed the vehicle and built it as a Discovery 130. It's got the Fourby Core 2 Hybrid turbo fitted now. Have a look at our facebook page for more info. It's quite incredible even if we do say sop ourselves.

[@james-_112]

how do i install a boost gauge to my land rover

[@DonegalOverlanding]

I do not have a boost gauge installed myself. I have a boost controller and I have not fitted it yet because I dont have a gauge. If you go to fourby uk page there is lots of information about land rover tuning. They also post up a lot on their facebook page. Dopnt forget to hit subscribe to this channel please, it means a lot to us.

[@james-_112]

@@DonegalOverlanding thanks

[@GRAY8618]

From experience I’d avoid the fourby egt guage! Gone through 2 probes and 3 gauges in 2 years, absolute junk! Brother has the stack egt for about the same length and no issues!

[@alex79buckland]

The engine ideal speed looks low to me well lower than the 300tdi disco's iv had

[@DonegalOverlanding]

Were your Disco's 3.4 ton?

[@willwest1902]

My truck stranded in 3rd gear does 90 and still pulls 😂

[@DonegalOverlanding]

Have you checked out what we are building Will? Look at our latest video teaser on here, two of them. We are transforming this old Disco into a world first, one of a kind Disco 130!

Terrible music 😂
