I = need a euro motor :P

I have a 3.0L M20 in my car. It goes alright, hopefully we'll have some vids of it pretty soon.

I tought the German E36 3.0 engine has 280hp
3.2 engine has 321hp :roll:

I'm not 100% sure of it

Euro 3.0L has 286, Euro 3.2 has 321. He's right. Except the euro 3.2 code is S50B32. :P

you're right, you are probably just looking at the torque #'s, he posted that the 3.0 had 286, and 3.2 had 321hp. check again

anyway, Stu (our Stu, McHenry that is) talked about how the Euro motor isn't neccessarily superior to ours. The throttle bodies are a pain to work around, and the brake booster nees to be moved or such. I can try to find the thread where he talked about it.

EDIT: Found it: http://www.r3vlimited.com/phpBB2/vie...t=motor+choose
Stu schooled me with his knowledge. I had said in a what-if swap, I'd go Euro.

You guys are completely missing the point.

Peak horsepower doesn't mean anything. What matters is where you're getting the power. Euro 6-throttle motors don't pull any harder than US single-throttles until about 4500-5000rpm. In BMW CCA Club Racing, the guys with built US 3.2's are pulling on the 6-throttle guys coming out of corners because of the mid-range torque advantage. Sure, at the very end of the straights, the 6-throttles have pulled a bit, but all they do is scream until 7500, 8000.

Also keep in mind that a Euro motor swap will require either a custom brake booster or NO brake booster. That's right, the 6-throttle intake manifold makes for NO room for a brake booster, unless you have one remote mounted. You will also spend more having a shop do the wiring and engine install.

Furthermore, the cost of PARTS for the 6-throttle motors is outrageous. Ignition coils are about $90 a pop, whereas they are about $35 a piece for a US motor. Keep in mind you have 6 of those sum'bitches. Don't get me started on the cost of upgrades for Euro motors (ECU's, exhausts, etc).

I would go with a US 3.0 or 3.2, OBD-1 regardless. They are a tried and true install, the parts are available everywhere, they have truckloads of mid-range, they pull like hell up top, they are cheaper than Euro motors, and the install and wiring is just simpler. Go pick up a 3.0 or 3.2, a swap kit, the parts needed....and throw it in there.

If I remember correctly Michael, it's an '89 325i? If so, you've just made your US 3.0/3.2 install a few steps easier.
You can use, from your car:
-radiator
-overflow tank
-tranny
-driveshaft
-diff (may want to get a limited slip)

The guys with US 3.0's and 3.2's with common upgrades are getting lots of power and torque out of them, with outstanding curves.

Typical bolt-ons:
-Euro HFM, 21.5# injectors (standard on 3.2)
-Custom software to match HFM/injectors
-pulleys
-fan delete
-custom intake setup
-exhaust (deletion of cats)

These guys are getting 230+ wheel horsepower.


You make the call, but I just put in my thoughts.


What would I do? Either a 3.0 or 3.2 US motor.....OBD-1, regardless.

4.4L V8 M60 engine with 5/6 speed. Now that I have seen one I'd love to feel the brut strenghth of it.

5 Liter 12 cylinder is to lazy for my tastes. To difficult to work on and and would not be my choice.

S38 in a E30 M3. Ruined a perfectly good M3 :(

[gstuning]

for anybody not living in europe, especially germany
The euro swap is not the way to go,

I have one and it´s the bomb, I love it, pulls extremely well everywhere, and will even more when I am done with it,

The cheapest swap here if you can weld is the M30 swap, the engines are cheap as M10´s and the wiring is cake,

Best always is the S14B25 of course,

I thought your e36 m3 wasn't as powerful though. Even if it is easier to fit, and is more powerful than the m20. There is aguy on the e30zone with e36 3.2 engined e30.

Stu

The US M3 engines:

s50 (95 M3) OBD 1- 3.0L = aprox 240hp
s52 (97+ M3) OBD 2 - 3.2L = aprox 240hp

I'm not sure what power the euro engines make but it's most likely alot more than the US versions

s50 - 3.0L = aprox 286hp
s52 - 3.2L = aprox 321hp

Thats the one I would love to do. Supercharge that motor and you have a Viper killer. I really wish there was more information on the swap.

It´s a S50B32 and it´s 321hp,

What you want is one of these :D

errrr. you guys know the specifications on the M30 engine? Thanks

Yea...it's a 2-valve single cam that pushes decent (at most) torque but not so impressive horsepower numbers, considering it's displacement. It also weighs about 110 pounds MORE than an M20.
