m50 swap: Vanos vs. Non-V?

[UNHCLL]

I just have a never-ending curious ......sorry if it's annoying :?

That is essential for a worthwhile investment.
Perhaps trent will chime in, once he gets a break from his current Porn flick....
I hear they are really "cracking the whip" on him this time.

If you're doing an M50 swap, I'd just jump on the first complete 2.5 you can get your hands on. Most ones you find are just longblocks or don't include manifolds, accessories, etc.

Find a 2.5 with the manifolds, power steering pump, alternator, a/c, radiator, wiring harness, ECU, EVERYTHING! Don't even worry if it's a Vanos or non, just find one. An E30 is lighter than an E36 by about 300-400 pounds anyways, so a non-VANOS will still haul balls in an E30, and you can alter things by getting a short rear end gear.

My dads '84 318i with a non-VANOS with a doghouse gearbox and 3.46 rear end pulled away from instructor driven 2.5 E30 M3's at the track, and 5.0L Mustangs on the street.

You will not be disappointed either way, just get ahold of the first motor you can find that is COMPLETE.

John Behrns (GMW) is selling a non-VANOS 2.5 out of an E34 (see FS section). I am going to his shop tomorrow so I can tell you what all it includes and if it is worthwhile for you.

Ah, forget it guys. :( Some other things came up...... my budget has been greatly altered...... shit :? I'm not going to be able to think about a M50 swap for a while. Advice: choose friends wisely and your know a good lawyer (maybe a lil cheaper one tho)........

Sorry Stu, didn't mean to waste your time, but i think this thread should go on, if anyone has any more thoughts on Vanos vs. Non-vanos.........

Ever wonder why BMW made non-vanos engine in 92 0nly? And Vanos engines for like what 8 years? Mhmmm

Ever wonder why a '92 325is 5spd ran low 6 second 0-60's in 1991 Car and Driver magazine?

VANOS was introduced to benefit cars with automatic transmissions and heavier chassis' (read: 525i)

Hey, i've been reading around, and it seems Vanos units are prone to eventual failure. If building a race car..... which maybe some would be, would Non-V be more reliable?

And as gstuning said,

The only thing that the vanos does is lower the torque curve,
maintaining the same torque values but sooner in the rev band, meaning more fun to driver, but also will not feel as fast, because with the torque always beeing so much and not change that much you don´t feel the accelaration that much,

If tracking the Non-vanos, it would not really matter. I guess for a street or daily driver, Vanos would have better gas mileage and a better powerband...... but for a racer, Non-V might be superior.

A lot of racers build 2.8/3.0.3.2 non-VANOS motors because VANOS isn't needed on the track, because it's topend change comes on at 4100, where you spend all of your time above on the track.

I am curious which year that have non-vanos and vanos? Since I am thinking about to get a 1996 or 97 Non-Vaons 3.2 Liters M3 Motor.

Those are both VANOS motors.

Non-VANOS was the earliest of these motors, 1991 and 1992. Seen in 325i and 525i cars.
