I'm been reading this forum one moment, because i want to buy a winter "drift" car :D of course diesel , i'm searching volvo 940 http://www.ss.lv/lv/transport/cars/volvo/940/ , after reading a few threads , ia have found out i need a td because it have more hp. But i have question, are they easy to tune up ? I have found videos with these volvo with original parts about 200hp ? is that possible and how ? at diesels i'm newbie

Welcome!
200hp on a stock engine is no problem. The injection pump is able to flow 200-220hp worth of fuel. Stock injectors will keep up also. Good head work, good turbo and large intercooler would be needed. I would also recommend head studs.

M90 is stronger and lever shift, m46 is pushbutton.

Can you tell by the Vehicle Identification Numbers (VIN codes)/Volvo/VIN Codes?

Around here, the M46 is worth under $200, so you just go to the junkyard and get another one.

Where is the PS fluid leaking from? That will determine the repair methods.

I got tired of jumping out second gear, m46 petrol or m46 diesel gearboxes whats the diffrence ?

diesel has a bushing on the end of the input shaft to fit the larger diesel pilot bearing. If you have M90 there it is supposed to be much better, but for the cost of shipping one here, you can break a few M46s.

In latvia we have about -20C in my city. And my diesel wont run in the morning, changed all the glowplugs, but nothing changed, glowplugs are working

You are sure your fuel isn't gelling? That's cold enough that if it's not winterized, that could be part of the problem...

How about injection timing? Is it smoking and trying, or nothing at all? How's the battery and other starting bits -- does it crank quickly or slow? What kind of oil is in it?

-20C is pretty cold! = about -4F... At that temp, especially if the motor doesn't have "new" compression anymore, it will probably need every bit of help it can get to start. If you're sure you have liquid fuel and a good glow plug in every cylinder, then it comes down to cranking speed and timing. Might start by cleaning all your + and - connections, checking battery condition, and trying some slippery diesel-rated synthetic oil if you don't already have it -- 5W30 or even 0W40. Getting it to spin faster can make up for other deficiencies.

Such a correct,helpful advice on every little (important) detail! -20C is no joke, btw

It is always a lovely, heart-warmer thing when a well adjusted engine simply `explodes to life` without `hesitation`! No matter how cold it is.

I truly appreciate how nicely mine is put together with the right combination of passion&experience!!! Million thanks

Just to compare things, I made a video, it might help some to observe a problem(s) you have with cold-starting.
Here it is only -14Celsius now (6.8 Fahrenheit) (even colder in the mornings) but it is cold enough to make my idiot ignition wiring to behave stupid. When temps drop to sub zero (especially when under -5C), some (old) wires harden so starting gets tricky: I have to jiggle&twist a bit, one of the connections, near/behind the ignition switch.
I live with it as a Winter issue :) but my next little project is to get a new(er) ign switch and illuminate all this. Finding time for it is the hard part.

In the video you will see+hear my idiot wiring thing, but most importantly you`ll see that no cranking was needed at all to get the motor started. After two days, between -10-18C, very windy too. It`s pretty cold, so 15mins of idling at 1000RPM didn`t produce any interior heat at all. :) I `hit` the starter and immediately the car runs. I played some with the timing advance switch too, in order to hear RPM differences. Someone on the Forum said it before: `it sounds like car`s eating a bag of rocks` :))

Obviously I do NOT use biodiesel this time of the year AND I have synthetic engine oil (http://www.mobiloil.com/USA-English/MotorOil/Oils/Mobil_1_Turbo_Diesel_Truck_5W-40.aspx)
AND I have a strong battery, no air in fuel and all plugs work as they should AND there`s some compression left, I guess :)

Sorry about background noises in the video. Phone probably couldn`t handle the vibration, so motor mount is next. :`)
PS.: do not completely rule out a wiring issue. PS 2: starting fluid?--> no lubrication!+torturing glow plugs :)

Oh, too many of these cars sadly became left behind, thanks to a neglected fuel filter. yes, just talk to workers of junkyards. But I believe you must have tried a very fresh fuel filter before blaming&touching the plugs...

Fuel filter i changed before winter, maybe thats the problem ? Glow plugs are new ngk , and the wiring is good. BAttery i changed before two months , but in morning when i went to car it sounds it will broom, but 5 seconds and the starter get slow. Oil change maybe need :( By the way -25C tonight

A crowd of people wouldn`t use NGK.
Buy Bosch!

I might only see -2C 5 nights a year, but those nights are always the worst on batteries...

I ran the cheapest Chinese glow plugs from Prothe for over a year, and they still worked fine when I replaced them with Bosch.

if your cranking speed suddenly dropped, it probably isn't the plugs. All battery terminal connections will be suspect though.

...because your car is very well adjusted :)

In my opinion, junkie plugs though, combined with a weak battery is the good old recipe for morning-time sadness. Especially at -25Celsius! :) (-13F)

Generally speaking, it`s not worth saving or experimenting on something that could easily lead to future headaches... A Bosch plug costs $10-18? which is $60-100 for a full set of 6 plugs, proper type, great quality; ... all this to avoid taking blood pressure medication after speaking with the diesel shop. $$$

okay problem solved, i bought additive for diesel and the problem is solved, now i want to change the gearbox
But i dont figure out the difference between m46 and m90. what else needs to change ?

you will need at least the front half of a props haft from an m90 car as well, maybe the full shaft would be more sensible, and then compatible clutch but i think that should be it?

Mounting the M90 in a 900-series car:

If you had an AW70, AW71 or AW71L automatic gearbox to start with, then you can keep the transmission crossmember since that is the same p/n as the M90 crossmember. You will also need the mounting bracket for the M90 (number 16 in the last picture of gearbox parts) since that is not the same as the AW7x bracket. The crossmember from the AW7x gearbox is then moved forward in the car and mounted in the front threaded holes in the body a few inches in front of the AW7x holes (yes, there are pre-made holes for using the M90).

If you had a M46 or M47 manual gearbox to start with, then you have to get the AW7x/M90 crossmember.

You will of course need the center console trim for a manual gearbox (the M46 trim works although it is not the same as the M90 trim).
All you need to know about the M90 (http://www.turbobricks.com/forums/showthread.php?t=94325)

my apologies, forgot about the crossmember and didn't even think about whether he started with an auto box! thanks for clarifying :)

So now that you're got a winterizing additive in the tank, it starts fine? Sounds like gelled fuel... Good thing -- an easy fix! :)

Some details on what you are starting with for a gearbox might help with information: do you have an M46 now, or an automatic? Some of the tbricks info may not apply if it talks about how to swap from an AW70/71/L to an M90, since the ZF automatic in the diesel cars is a different setup than the gas AW trans. The ZF trans crossmember is the same as what an M46 uses. The trans and motor mounts are also matched to some degree, so switching from one type to another type on the trans and not changing the motor end might make things sit funny...

Yes, it was gelled fuel, now it starts fine :)

I have a m46, but i think i will buy another m46 because its more cheaper about 40$, if i want m90, there i will need more parts not only gearbox :)
