anyone have a Euro S50B32 in their E36?

How hard is the swap? where to source the motor? will it pass the emission test?

Easy

Easy swap if you have an OBD1 car (92-95) and don't mind swapping the gearbox, driveshaft, cooling system, DME, and wiring harness, and accessories. You may also need the instrument cluster, but I'm not sure.

The main obstacle to this swap is finding an S50B32 motor in good shape for less than $7500, plus the cost of installation.

There are lots of turbo and supercharger kits out there that you can buy used for $2500-3500, and a tubo'd E36 (even a 325i) will be faster than a Euro S50B32. This might be a better option. If you do the install right, and take the proper precautions, it will also be just as reliable.

An AA or Dinan supercharged S52-powered E36 puts out about 400 hp (at 8 psi) and there's lots of room to grow. That will translate into a 4.5-4.8 second 0-60 time and mid 13s in the quarter.

Just sayin it's an option.

Install a supercharger less headaches and more power.

I don't think it's worth putting that engine in. Here is a link where you can buy the engine from:

I like the idea of the euro engine instead of a sc kit - it's the engine the car was meant to have...

all euro M3 engines are S50's, not S52

I did the swap on my 98 328is, WELL worth it if you can source a good engine and do the swap yourself. The car pulls harder than E46 M3. Forced induction can't touch it in terms of powerband and reliability.

To the person who posted that it is an easier swap into an OBD1 car, this is incorrect. Have fun wiring EWSII into your OBD1 car. My swap was plug n' play other than re-alignment.

You will need to change: exhaust (motor back), radiator (highly recommended), clutch (if non-M).

Any 6 zyl tranny, driveshaft, diff will work. Try to get a LHD engine as you'll have many less headaches.

All that said, I did the entire swap in my garage with a mastercraft socket set.

If anyone has a serious need for an S50B32, I will bring them in on a per order basis with a deposit.

How much can you get an s50b32 for?

$6000 is a starting price, then you have to buy the cats and muffler ($800). Plan on spending around $2000 for small parts and I highly recommend the larger core euro radiator and oil cooler ($500).

I am not a mechanic so I spent an additional $2000 for the swap.

So realistically, when it's all said and done, one should expect to pay about $9000-$10,000 installed? Damn that's steep. You might as well sell your E36, add that $10k, go to the states and pick up an E46 M3 (They go for as low at $15k in the states).

Although having an E36 with an S50B32 would be very very nice. I could only imagine how nicely it must pull.

kick your tires? you mean inquired about how much you were asking? Yes I asked how much you were looking to get for the S50B32 and the price discouraged me from even going that route.
