5 pot TDI?

[oldskool rich]

thats right.
most audi boxes are both, but not all

you can fit an A6 TDI quattro box to any TDI/IDI i checked this therory at work the other wk
im using sutch an application in my caddy, you can pare this up with the old locking diffs and hav sum fun

Cool. When the time/money mix is right, I'd like to get an Audi V6 TDI for one of my VW campers, for more grunt & less fuel consumption. KEP has the adapters for VW or Porsche trannies. Gotta finish the German V6 gasser conversion on the other camper first.

Thanks for the info.

Smokr:

You might want to re-consider that.  The 2.5 V6 is VERY heavy, whereas the 5 banger is reasonably light.  The 2.5 can use all of the hardware from RSA that bolts in the 2.6 gasser, includng hyrdaulically dampened mounts.  We had the same thought as you, but after a lot of consideration, went with the 5 cyl instead (and had Giles build a nice MTDI pump for it to keep the installation all mechanical).

I've always wanted to see a 2.5 v6 mtdi using a cummins 12mm pump. From what i can see it would bolt in no problem! Those pumps are dime a dozen around here.

[CdnVWJunkie]

Black dog, I presume you mean the VE 6BT CTD pump?  That certainly would make for an interesting conversion.  Lots of info out there on the 6BT pumps some making huge power.

[oldskool rich]

the V6 is a crap engine, the heads always go wrong and there a bastard to work on, also weight is a massive issue too, they do bout 30 MPG pretty *** for a diesel , ive been getting 50 out my 5 pot you may as well stick with petrol

how much does giles charge for a 5pot injection pump?
please can sumone tell me how to contact him?

[theman53]

Vendors section of this forum. If you send him a pump drain all the diesel out before shipping...ask me how I know 

[theman53]

Why not give you the info...I have time now

you could also look at the merc sprinter 2.9 tdi the early ones are mechanical ve pumps and 5cylinder but are chain driven so it would depend on whether you could swap shafts or fit your pulley some how

[oldskool rich]

oooo, i like the sound of a merc pump, tell me more, whats it off?

i know some very impressive machinists that can make anything happen

is this a straight swap, besides the pulleys? I have audi 100 C3 2.0td 5cyl, the engine is broken , so id like to replace it with  2.5 tdi 5 cyl but without ecu. I have read the faq about m-tdi pumps , but most of the information is about 1.9 tdi. Is it possible to build a franken pump using my  2.0 td pump and 2.5 tdi pump or are there some factory meh tdi pump which could be used. 

[55eta]

forget about the merc pumps as they are e tdi on the sprinters i  got them mixed up with the 2.9 idi,s as used on the merc 600 series vans but by the sound of it the audi 100 2.0-2.5 tds sound a good bet but probably like rocking horse sh#t over here also vw lt2.5 N/a engine is 5cyl but i am not shore if it is electronically controlled like the sdi,s

[oldskool rich]

ok bit scared that the injection pump will cost me the same as the whole car 

apparently will need to run 60psi to get anywhere near 300bhp

according to my mate that tunes MR2s PSI meens nothing and its all about air flow, which i strugle to get my head around but its been tried and tested according to him, so im looking at the holset HX40 because its massive. anyone got any thorts on the matter? will that be too laggy? so many people telling me different things its hurting my head

fitted my S line interior, its starting to look like a half desent car, getting big brake conversion after xmas 


any more info on pumps and how to covert them to MTDI will be grately appreciated
no disrespect to giles and im sure hes worth it but i just dont think i can afford it 

[burn_your_money]

according to my mate that tunes MR2s PSI meens nothing and its all about air flow, which i strugle to get my head around but its been tried and tested

He is correct. Pressure is restriction to flow.

If you are running 15 psi on a stock head it will flow say 150 CFM
If you port that same head and run the same 15 PSI you will now be flowing 200 CFM because there is less restriction.

Make sense? I just made those numbers up by the way.

[MJF]

Where did you get that 60psi? Boost doesnt make power, itīs the flow like your mate said. HX40 is "a bit" overkill for these engines, fine up to 500+hp in di engine. HE221W @27psi made 280hp and thats pretty much what you can get with 11mm pump and stock head.
