5 pot TDI?
«

December 03, 2009, 09:06:09 pm »
Hi, i just bort an AUDI A6 2.5 TDI, with engine code AAT
I was told that these can be increased to 300 BHP just by using a bleed valve, is that true?
also does anyone know the difference between this and the AEL (140 BHP) engine?
i want more power and i have alot of goodies at my desposal, including chargecooler and M112 supercharger. just not sure what will work best? will i need nozzles?
i need input, i will update my progress, will try to get some videos on here if i can make sumthin worth showing off
thanx in advance xx

Few threads on tdiclub at the moment, not that specific code though.
Got any 4 cyl mtdi parts knocking about?

Not true.
DSS Ultime2 injectors, FMIC, 3" exhaust, camshaft, HE221W and custom programming:
281hp/594nm.
AEL has bigger injectors and ofcourse programming. Othewise same engine. Bigger injectors is the first thing to do with tdi.

aat has a small k16, .187 injectors and a small intercooler, think of it as an early 1z with an extra cylinder.
better design on all the manifolds though (no D shape on the intake, but its not necessary as it doesn't make a sharp turn)
that exhaust is a piece of art compared with 1z ( and gt2556v bolts on with no mods
)

what M-TDI parts are you after? i have access to lots of parts, try me
i have no clue about electrics, infact i hate them, so forgive me if this sounds like a mega stupid question but where is the "programming" kept?
will that be the ECU? can i just change mine for an AEL one? or should i just get mine re-maped, i dont want to beet around the bush, i want big power, but i dont want to spend Ł300 on a cam to get an extra 5bhp, i spent Ł80 on my AAZ which doubled it power, id like to do the same hear if possible
So what is my best course of action to get as much power for little money, using bits off other VAG cars is best for me but i will spend money if it will get me results
what about my supercharger? wud that be better than a turbo?
you sure the gt2556v will go straight on?

When my friend did a 5 cyl turbo conversion on a eurovan natural, swapping the LDA bits on was a pretty easy job. Its still just a ve pump after all!

there are IDI pumps for those engines (2l audi100, 2.4l t4...), you can make a hybrid just like on the 1.9mtdi, rotation isn't something you need to worry about if all the parts come from the suitable engines.

Actually an AAZ LDA won't work. Like oldskool rich said, everything will be backwards, or rather on the wrong side. I think Giles needed 3 different pumps to make that mTDI.

like I said, all coming from VW I5's
case from a 2.4, head from the eTDI 2.5 (11mm)... doable, better, already done as proven by the video

Programming is in ecu. No difference is it AAT or AEL, youŽll need re-map. Even if you go with mech pump, youŽll need bigger injectors to get more power. Maybe 170hp with remap only.

wow, thats amazing, never seen an engine tested like that before
where can i get the biggest injectors for the cheapest?
that pump looked like it just had an LDA off an AAZ on it? may it is just a swap?
if not what engine code do i need the pump off? TBH I wont even have to take the pump off, i can just swap heads cant i?
are we saying no to the supercharger then and yes to a gt2556v?
again no idea where to get any of this stuff from

I would try HX30, He221, GT32 or similar wastegate turbo. AAT/AEL/Volvo ECU can not be programmer easily to control VNT.
