I bought a 325i swapped with eta engine

[SeriousBusiness]

turbo m50 vs turbo m20? lets see that :)

Most of my friends are convinced the M20 cannot produce upwards of 400whp on a moderate budget and forged pistons/rods. Bunch of M50 fanboys I say, I think either engine would surprise with a built bottom and snail attached.

Though stock for stock, I'd like to see the limits of either engine, power wise, with a turbo.

Never really researched it though..

I'm still not sold on the m50 swap. I did one recently at my shop in a friend's car, then did the 885 top end and Motronic 1.3 in my car. The m50 went in an 87e and my car is an 86 es. Neither of us swapped gears or trans (both 2.98 diffs, Getrag 260's). We have yet to race since he goes to NY for the summer and I just finished mine, but have proof of both on video, and drove both cars of course since they were done at my place haha.

Here's the video of his car. For fair comparison (timing of the vid start is off), his car is at 10mph at 0:02...

and here's mine, 10mph at 0:04...

his hits 60 at 0:10 and mine is at 0:11. I'd say the stroker is a close run for the m50, maybe I'm crazy?

You are not crazy at all sir. I am a HUGE M20 fan myself and am still on the fence about building a little M20 stroker, or going for the M50. For the money spent, the M20 stroker will be faster (marginally), but the M50 will have DOHC, possibly VANOS (which I could probably do without), it will be a more modern engine as well. Not to mention the M50 will be a stock platform with MANY areas to upgrade in the future. Once you stroke the M20 and do some machine work to make it faster than the M50 you are going to struggle to upgrade from there (and stay N/A). Then there is the increased upkeep (financially) of the M50 (basic engine accessories). Starters and alternators for the M20 are just plain cheaper, by a long shot. Though the M50 has COP ignition which is VERY nice considering the M20's 140$ spark plug wires.

That is some of my take on it, and its a real toss up on this subject for me. I was just trying to be witty and tell the OP to ditch the tank engine.

Put an M50 in it and forget this ever happened.

It's at my mechanics shop right now. I'm positive it has an eta engine in it.

perfect rage cartoon:

buying e30= :)

its a 325i = :)

with an eta motor..



FFFFFFFFFFFFUUUUUUUUUU

Subtract 1hp per year of existence (23), it'll be about right.

ROFL.

Dunno, my car is 25yrs old, never dyno'd it, but I took it to the track and was able to squeeze 16.8 @ 80mph, 2.1 60's. Don't know what they were supposed to do, but I actually just changed out the OEM shocks that were on there for all this time haha. Mileage has more to do with it IMO.

[VinniE30]

So basically what you guys are saying is that my car is probably making no more power than a stock eta and if I bring my car to the redline it will destroy it since the eta is supposed to only rev to ~5000... damn.

[AndrewBird]

Post a picture of the engine and we can tell right away whether it is actually an eta or not.

[bimmer_E30]

etas are good for one thing.


Good gas mileage

What do you mean by pseudo-seta?
