reb78 424 Posted Monday at 09:14 PM Share Posted Monday at 09:14 PM (edited) I have run a 300tdi pump on my 200tdi for a fairly long period whilst mine was being reconditioned. It ran the same to me as the driver but I don't know if you would notice any difference if the differences are minor? Edited Monday at 09:15 PM by reb78 Quote Link to post Share on other sites
monkie 324 Posted Monday at 09:28 PM Share Posted Monday at 09:28 PM Was it a straight swap, you didn't have to make any adjustments to timing or anything? Quote Link to post Share on other sites

I borrowed it from vulcan bomber here. We fitted it on the drive and just timed it up as normal using the timing pin. I probably did a few thousand (maybe 5000) miles on it but you wouldnt have known the difference when driving. Quote Link to post Share on other sites
Eightpot 235 Posted Monday at 10:03 PM Share Posted Monday at 10:03 PM 300/200 pumps are direct swaps, have also used 300 pumps on 200 engines, no difference in operation. So from the data I can find so far, aside from some minor timing differences there seems to be no difference in the pumps internally. Crack pressures on 200/300 injectors seem to be the same - 200 then 280 bar So if pump is the same, injector pressures the same, the slightly bigger nozzle holes would alter the spray slightly - maybe in conjunction with the modified pistons/combustion area it's part of the revision to remove some of the clatter when they changed to 300?

RRC200Tdi 11 Posted Monday at 11:18 PM Author Share Posted Monday at 11:18 PM I just got off the phone with Bosch USA and neither the 200Tdi 300Tdi nozzles are available here. The tech service person said they are both listed as 'out of stock' which he surmised to mean that they no longer have access to them. He recommended I search the internet 😪 I have created a table with all of the DSLA145P nozzles so you can reference the different types. nozzle table.xlsx 1 Quote Link to post Share on other sites
RRC200Tdi 11 Posted Monday at 11:21 PM Author Share Posted Monday at 11:21 PM Note, it seems we are limited to the nozzles that indicate 2 springs,so there might not be any other alternatives Quote Link to post Share on other sites
Eightpot 235 Posted Tuesday at 09:31 AM Share Posted Tuesday at 09:31 AM Very useful thanks - so in summary we're stuck with slightly unobtainable genuine 200tdi nozzles, aftermarket 200tdi nozzles or 300tdi nozzles. According to my very fallable maths, the total area of the 300tdi five .26mm holes is 17% larger than five .24mm holes. Seems like quite a jump but I wonder if theres a noticeable difference in operation. Quote Link to post Share on other sites
monkie 324 Posted Tuesday at 09:52 AM Share Posted Tuesday at 09:52 AM I still think this case is still very much open. I haven't proven the ebay nozzles to be fakes. I'm going to perform some tests to compare original (as far as I can tell) used nozzles, ebay nozzle, Eurocarparts nozzle, ebay 300Tdi nozzle on a 200 Tdi injector) for opening pressures and spray patterns... watch this space. (my tests don't involve angle/bench grinders ) 2 Quote Link to post Share on other sites

Happy to sell you the nozzles at cost price with the proviso that I want to see you test them with a plasma cutter Quote Link to post Share on other sites
RRC200Tdi 11 Posted Tuesday at 06:49 PM Author Share Posted Tuesday at 06:49 PM FYI, I reached out to Turbo Diesel UK and they quoted me a price of $58.86 per nozzle for genuine Bosch 300Tdi nozzles. I don't know if that is a good price or not, since I haven't researched 300Tdi nozzles at all, but so far they are the only genuine 300Tdi nozzles I have found on the web. @monkie I am eagerly awaiting the results of your tests!

Eightpot 235 Posted Tuesday at 07:07 PM Share Posted Tuesday at 07:07 PM Funny - I messaged them today as well and got a price on 200Tdi nozzles - quoted £48+vat for genuine Bosch kits which include O rings/washers. Also quoted £30+vat for DTP nozzles. Not a bad price but the address checks out to be a residential house. I have had similar prices from a couple of diesel parts specialists. Also had a quote from Darwen diesels on 200 nozzels - £15.25+vat each for DTP brand. I think at that price I might get a set and check them out. Quote Link to post Share on other sites
reb78 424 Posted Tuesday at 08:38 PM Share Posted Tuesday at 08:38 PM Did I imagine it or did someone on here have a tester? was it @oneandtwo?? Quote Link to post Share on other sites
oneandtwo 109 Posted Tuesday at 08:59 PM Share Posted Tuesday at 08:59 PM Yes, I have a Hartridge tester. Quote Link to post Share on other sites
Eightpot 235 Posted 25 minutes ago Share Posted 25 minutes ago 200tdi nozzles made by DTP have just arrived. Compared to an old 300tdi nozzle the holes do appear smaller - possibly due to wear but I suspect they may well be the correct spec rather than rebadged 300 nozzles. Will pop them in soon and test.

If I can get the injectors and nozzles to you, would you be able to test them for us? I often go to Royal Cornwall Hospital for work so I may be able to drop them off (socially distanced of course).
