So i bought a 1994 Volvo 850 Turbo Wagon, needs engine.

Got a new engine for it, was auto, i wanna do a 5 speed swap on it? the thing is, the 5speed came out of a non-turbo, will the 5speed handle more then 400hp? and how much you think the Auto trans can hold?

What would be the best thing to do?

 

need reply fast

II. Transmission

A. The stock automatic transmission doesn't seem to like seeing power above 300bhp. However, some people have been running higher amounts just by doing simple things. There are two very easy and very significant things to do that will help the life of your transmission great amounts. One is flushing your fluid (also upgrading to better fluid helps), and the other is the installation of a transmission fluid cooler. With these two simple things, these transmissions (in good shape) have held well over 300 horsepower, though they are still far weaker than their manual counterparts. You will find by checking your transmission fluid regularly after modifying your car greatly, the condition of the fluid deteriorates pretty rapidly. Flush the fluid again as soon as its condition has deteriorated.

B. There are to my knowledge two manual gearboxes for the FWD cars, the M56 (available in H and L versions) and the M59. Some people have gotten the M66 from the S60R to work in these cars, but I will focus on the 850's offerings. The M56 has an open differential, but is supposedly stronger than the M59. The M59 however, was used in Europe in the R's, and came with a high power-handling clutch and a limited slip differential. The M56H and L differ only by gear ratios, both being very strong transmissions. When using the Volvo manual transmissions, the R clutch kit should be capable of handling most builds regardless of driving style, until you start approaching the 350-400 whp level. In my car with 19T turbo, stock injectors and intercooler, and Upsolute tuning, I ran 13.31 at 107.4 mph, this with the M56H transmission and R clutch.

What do you have done where you're putting down more than 400 HP?

 

Exactly! I want to know a little more about the "1995 Volvo 850 Turbo Wagon - 536hp" that's in his sig...

 

What cars can I get the M56H and L setups out of? I'm looking for a donor car.

 

m56H is out of the non turbo 94 and up 850, the M56L is out of the 1993.

 

So I can get the M56H out of a '97 850, NA?

 

Sure can.

 

that is good to know I was just going to ask someone about the manual trans from a non turbo.... I like to try and see if I can find this stuff before I ask..... guess I will need to find a donor car for the pedals and other things......

 

Thank you for looking a little before asking. That is really appreciated!

Getting a donor car is the way I went. I wanted to make sure I had everything needed.
Read up in this thread for all the little parts you'll need.
What To Know About A Manual Swap - Volvospeed Forums

 

Any manual 850.

Yes. But if you put it in a car that has an M56L, you'll have to tap into your ABS sensor for the speedometer signal since M56Ls uses a speedometer sensor on the backside of the transmission and the M56Hs do not have the speedometer sensor because those years they used the ABS sensor for the speedometer.

No. 94s and some 95s are L's. 96-97 is the guarantee H.

 

Find a donor car would be easiest, but in my opinion, you should still get a new master and slave cylinder as well as the clutch and release bearing. So unless you can find a donor car for relatively cheap, it also may be easier finding a manual swap kit, as they are pretty cheap these days.

 

Does anybody know anybody who has a complete manual gearbox kit for sale for a '95 850???

 

I would like to know that as well also I would like to know how much more difficult it would be to use the m66 I would like to the 6 speed as I like to the closer ratio gear box ( I like to drive the twistys more than straight line shoot outs....)

 

You will find that the gear ratio in the M56 is close enough, not to mention is bolt and go. Very simple, straight forward, swap. I didnt say easy in there, its just made for it. I did it alone and wondered several times why I was doing it. If you have a friend offer to help dont let them escape.
After the swap.....Magic happened. Its just beautiful to hear and feel your car.

 

If you have a '94, you'd probably be better off getting the M56L, correct? that way you dont have to worry about splicing into things for the speed sensor signal....is that correct?

 

so the m66 would be a wast of time and money and that the m56 is the way to go, so would I need the M56H or the M56L I have a 94 turbo wagon I dont know if my car has the speedo gear or sensor.
