300tdi setup/tuning

Maybe stick a dti up the arse of the injector pump just to confirm that is it the correct lift at tdc?
I cannot remember the numbers 1.4mm? but a quick google should give you an idea.
The inj pump sprocket has no keyway, so in theory the timing could be spot on with the timing pins but actually be wrong/out.

There are some vids on youtube, doing it is not the issue, access is the issue, especially on the 300 as I think the vac pump is in the way? there used to be kits with a 90 degree adaptor for tight access.

Edit just stick this into youtube search and have a look, bosch ve pump dti gauge, load sof results.
On the plus side you get to buy some more tools!

Cheers for that, very interesting.

What I am really looking for is someone to do all this for me.
Set up the FiP
Make sure the turbo is right
Set the EGT and the boost etc etc...

Does anyone know of a 300tdi engine tuner that can do this ?

Engine 710 are meant to be really good, out by South Queensferry, either that or Gibsons Autos in Ayr. Both will definitely be able to help and I can vouch for Gibsons but I don't know what the cost will be

I called Engine 71 a while back. Twice about 3 months apart. We discussed things in detail.
They don't have a boost gauge let alone EGT measuring capability. I imagine a DTi gauge is beyond their comprehension.
"Without these essential tools, how can you set up my 300tdi ?" I asked ... "We can't" was the honest reply.

Strathearn Engineering said they could (which is why I took it there), but they lied - which is even more dissapointing.
I'll call Gibsons in the morning (Fri).

egt & boost guages are cheap......

Rich.

Either that or try Gemm 4x4 in Larbert, they used to be really good and do parts and spares as well as have a landy scrapyard which had served me well over the years. Haven't been to them in a long time but the owner George is always really helpful

TBH as it is old school, you are going to struggle to find any pro that will want to touch it.
Iirc 300 has a blank plate on the exhaust manifold so fitting an egt should be quite easy, boost gauge is also an easy job.
Maybe fit these yourself and see what results you have at the minute?

I've called Gibsons, spoke with James, will update after i've been along (circa 18th October).

Update:
So I took my car to Gibsons. Nice folk with a good setup. plenty of room and some interesting ramps (that they rest the chassis on).
James showed me around and we discussed the job in hand, ie set up the engine, check the fip timing, boost, measure egt, figure out/fix any issues etc.

They had if for a full day and checked it over thouroghly. The fip and camshaft timing was good, the boost @ 16psi. They ran the car without the air filter, bypassing the intercooler, adusted the tappets, checked and adjusted the smoke ring and load screw basically did everything i'd done/discussed. Statements from thier 'report' include " Vehicle found to be flat, lacking power and laggy. Adjusted the injector pump numerous times and road tested repeatedly still flat and lacking power".

Given that this is exactly what I said was 'wrong' when I called and when I dropped the car off i'm a bit dissapointed with the £350 + Vat bill. however the following statement on the 'report' is helpful.

The conclusion is that "Once the vehicle is up to full speed and on full boost it goes ok, but is very slow to pick up which may be the turbo impellor that is worn or badly angled".
Given that this is a brand new, reconditioned turbo (from Turbo Rebuilds in Preesall near Blackpool) that I fitted at the end of March, with less than 1000miles (less than 600 probably), I am a tad disgruntled.

I've now spent more than I originally paid to have the turbo rebuilt (new core etc) and the turbo is "unfit/unsuitable for its purpose".
Thanks TURBO REBUILDS Ltd <https://www.turborebuild.co.uk/> for a not inconsiderable waste of my time and money.
I plan to get another and swap it out and then decide what to do with both the turbo and the company that supplied it.
Myself, a couple of mates and now 2 specialist garages (Strathearn Engineering and Gibsons Autos) have concluded that there is something wrong with the turbo.

@miktdish

Why not fit an egt and turbo guage?

Plus check the fuel pump using a DTI and the timing at the same time. Check your tappets.


None of it is rocket science. See if you can find a good 2nd hand std turbo, there are lots about as people change to a hybrid.

Cheers

So I had checked it, but I am just an oik, I am not a Gibsons or a Strathearn or (enter the name of your reputable LR garage here) so when I discuss this with the receptionist at Turborebuilds (apparently you can't speak to the engineers - company policy) and she gets back to me with - "our turbo is fine, I have spoken with the techs and it was tested good, it must be your engine/FiP/abilities".

And then when you do take it to (enter the name of your reputable LR garage here) and tell them you have checked the boost, the FiP timing and the tappets (because it's not rocket science) they then check the boost, the FiP timing and the tappets (because they don't believe you have the ability to do that yourself and because they make money) they say that "Once the vehicle is up to full speed and on full boost it goes ok, but is very slow to pick up which may be the turbo impellor that is worn or badly angled".
Well to be clear, Gisbsons said that, Strathearn said "There is something wrong but we don't know what it is because we don't have the tools to check".

So I phone that info into Turborebuilds and they say (A) there are no notes on my account to say that I have had a problem before and (B) "i've spoken to the techs and we checked, it's probably something else, your fuelling maybe ... You can send it back and we will test it".
I dont think the receptionist knows what a turbo is, it's not a lightbulb. it doesn't just unplug.

I am very much an engineer that understands the relationship between components, if the fuel is at the right pressure, is delivered at the correct moment, there is enough compression to raise the temperature above the flashpoint of the fuel etc etc. The turbo will spin up as the exhaust gasses pass through the vanes and the increase in pressure allows more fuel into the cylinder and around we go ...
It can all be measured and setup and physics takes over.
I have long suspected that the A/R ratio is wrong on the CHRA/Core assemby so that it needs an greater flow than a 300tdi outputs below 1700rpm.
The fact that Turborebuild insisted it was set ~ 17psi uplift (insisted on several occasions) yet when I bought a boost guage and tested it it was only 12psi going uphill in 3rd with over 2000rpm.
"Your boost guage is probably innacurate" they said.
"Can I increase the boost and will that effect the warranty" I asked
"I've checked with the engineers" said the receptionist, "and its OK this time" (I wonder if they will 'remember that').
Well my boost guage was innacurate as I thoiught i'd set it at 17 but Gibsons said it was 16, but everything else is spot on.

I've bought a new turbo and as soon as I have all the bits available I will change it over and send the Turborebuild one back to them.
Here's a pick of the new one.

Bit different but was readng a thraad on a boat forum the other day, twin engine set up, one with recon turbo, other with brand new turbo, engine with new turbo went better and made more boost.
Conclusion was that not only does the cartridge wear, the housings also wear/corrode away.

I fitted the VNT turbo which helped ....



Some months later, new (recon) injectors fitted and the engine is a whole lot better, still not set up (fueling wise) 100%, but the new injectors have made a noticable difference.

I did get another FiP which if I can't tweak the original I will sent to Bob to check over.
