What sort of modifications were done to that E28? How does it have so much power,especially when Diesels from that time were so slow that walking would have been faster? It goes extremely fast for a diesel of that time. Of course a new 525d would be much faster, but your E28 has a lot more than the 116 bhp its supposed to have.

Currently it has a output of 192HP and 395Nm at 1,5bar boost pressure. Bottom end of the engine is stock but cylinder head is finetuned. Boost-pressure-enrichement-dev­ice of the injection pump was further improved. A 525d would have no chance at all due its additional weight!

I think a well maintained 524td with its original rating is´nt slow at all, once in a time it was the fastest diesel passenger car of the world!

524td was the first bmw great dieselcar... the engine is stupid designed (12valve m21 type, with a BIG turbo with wastegate, and a great cooling system... but cilinder internal temperature be so HOT, cause a intercooler can make the "fragile" 524 a GTI killer!

I need that handtune... you just can install a rear diff from a 535M or alpina, that make you car better aceleration, and cornering.

Hi Duke, if you want to boost the output of your e34 524td you will have to increase the boost pressure as well as the setting of the injection pump. On a e28 it can be done by a harder spring on the wastegate and a modified boost-pressure-enrichement-dev­ice of the injection pump respectively.

The electronic injection-system of an 524td e34 is a completely different matter since it has two control-boxes vs. the straight mechanic injection pump and boost control of the e28 td.

the old petrol BMWs(the more powerful one especially) do that too is it the transmission that causes it? I hate the sound of it, you cant hear the straight 6 petrol as well as you should :)

[stupidbychoice]

Hi, transmission is stock. 5sp. manual with LSD (gear ratio 3,15). M21 are loud when they are idling, okay, but at speed most people actually won´t identify it as an diesel-engine.

Well it's true and you must belive it,when BMW put 524TD on the market it was the fastest diesel on the world,you must remember it was mid 80s and diesel engines by other company was slow,noisy and most of this engines was't have an turbo.M21D24 by BMW had turbo,6 cylinders and 2.4l so it was a hell of disel when in this time VW had 1.5/1.6 4 cylinders non-turbo noisy diesel in his cars.

great car!, i have an 87 bmw 535i and they are great, dependable, and VERY fun to drive!

Just bought an E34 524td (1988) today, with the intention of getting similar power out of it too... so I was wondering what 'fine tuning' has been done to the head? And is that 1.5 bar (22psi) on the stock turbo?

Love your car, love the BMW in general.

hast einen 524tds draus gemacht :) sehr schönes Auto !!!

My 84 td is even faster, but only downhill, I clocked it up to 235km/h hahahaha. Seriosly, mine with stock tires (175/70 R14) can reach 200km/h easily and the engine stile stock with 115km done. The problem with the stock tires is understeer, lots of understeer.

[AndreiMsauCalu]

i wondering for the modified one the mcanical injection has a pressure sensor? if ies the injection setteing can work with high efficienty at low boost? like 0.1- 0.2 ? i meen the injection is now set for a higher flow of diesel always or only in high boost? can the car still get 8 l of diesel /100km in city if not raced with?

[craig9843]

I would never do that to a car. Way too nice of a car to do that.

[perkinsmaster]

lol ? das ist dochn 6 zylinder un im vergleich zum D24 TDIC von volvo (VW) der auch keine 130 ps sondern nur 122 und das mit LLK hat ! läuft ein bmw wesendlich ruhiger nur so zur info ;-)
