Well if it doesn't fall through then I have bought a 325 tds estate from the ebay. Hopefully to pick up on Saturday morning. It already has an endtuning eeprom chip running approximately 175 bhp but obviously that's not enough. Now should I go ahead with bigger pump turbo clutch etc on this engine aim for 300 or 400 hp or attempt om606 conversion taking into consideration I have limited tooling. I do like the om606 idea but I also like things that are not too far out of reach. Suggestions tips pointers etc are greatly appreciated!

Very nice! I've got my fingers crossed for you!
Idk if it'd work but what about replacing the bmw rotary pump with a 603 inline pump (dieselmeken'd) and collect all the same performance parts you would for a 606 build so that if you end the life of this engine, you could be ready for a 606 replacement.

That is a champion idea crd. I have a bit of an idea of whats involved in the conversion bell housing rewelding, flywheel from the tds on to the om606 and what about the alternator wiring and fuel supply

Has anyone converted the tds to inline m pump? What would be involved how would one get the pump timing matched to the engine timing. If both pumps turn at half engine speed then would it be a case of just having the same sized pulley that came off the tds engine to get it to turn at the same speed?

I think you'll never get 400hp from TDS, maybe 300hp max and even then it will not last long. I've read many forums and tds has weak cylinder head, also common problem is broken crankshaft and they broke even when engine is stock. My friend has stock 325tds and month ago crankshaft broke half between 5th and 6th cyl.

my dutch pump guy wrecked my 12mm plunger Sad so im rolling with the 10mm head an a cummins cam plate. witch is realy crap i hope i can get the m pump working on my crank case. outher wise i need to have a chat with mr meken so he can sprinkle some magic on my rotary.

no the 12mm would only work properly with less agressive cam plate(needs shimming the 12mm will start to float at 4000rpm with very flat 524td cam plate). but now i am back to 10mm i can use a more agrassive cam plate. altough this is not prefered becous my injection time is way longer with 10mm long stroke. longer injection can be compensated with more static advance but...... and here comes the biggest problem of the rotary, on stock ip housing the max advance is 14 degrees....

So how many degrees is each mm advance? So far I have evry mod the pump/ecu and just tightened the wastegate but haven't tested how much boost it's at. It felt quicker with the evry mod and no extra boost so hopefully quicker still with more boost. It already has an upgraded ecu chip too

So soon (tomorrow hopefully) I should be receiving a custom 14mm rotor head and 3 mm camplate. Aiming for the big numbers so I'm on the lookout for an eaton m62 supercharger found on some Mercedes petrol engines. When I have the head off I am going to mill out the exhaust ports and polish them and the same with the combustion precup exit. At that point I'll swap the head and camplate on the pump and replace all gaskets springs etc. I might run a twin pass intercooler one section for the supercharger and the other section for the turbo.

Perhaps, I also bought new spring and mount kit specifically for that rotor head think this will help also plenty pre-pump pressure from a better in tank pump and a supplementary pump will help. The revs won't be going much higher anyway and the camplate and rollers will be getting sprayed with an aerospace grade molybdenum anti friction coating. When I have the head off I will also plasma coat the combustion chamber precup with a very high temperature resistant ceramic coating from my work to keep as much heat in the cylinder doing work.
I wonder if it would be worthwhile doing the piston crowns too? All that heat from the combustion chamber hits one part of the pistons leading to uneven heating so I imagine it would help.

mwa easerly milled, and can be done without.
a blocking tool to block the crank in tdc.
also a blocking tool for the camshaft.
a pump puller.
and a ve dail to time it correctly, could also be done with a micrometer and a magnetic clamp.

the puller is something you defenatly need if you want to remove your pump it prevents the sprocket from falling in your cam gear case and makes pushing the pump conus from the sprocket easy.

post your findings i think 14mm wil be to mucht to keep from floating, a 12mm already needs some serious reinforced internals to acomadate the stronger springs. i will try this winter to modifie my pump some more, i also have drawings for a m pump adapter so i can always go full rage quit on the rotery pump.

Am I right in thinking M21's are timing belt driven and M51 are timing chain? Is there any issues when converting the 325TDS to the mechanical M21 pump?

Bit of a long shot but here goes. Anyone know how many degrees start of injection is for Cummins 6bt direct injection is compared to bmw tds indirect injection. I have a cummins camplate in my pump and have pivoted the pump back as much as possible to increase advance and it runs like a proper tractor. So it's too retarded due to the late injection of direct injection camplate. Any ideas? Otherwise I will slacken chain and advance pump more.
