explain this to me

[screamingbmwe30]

lets say person "a" spends 2000+ on a 100K+ mile engine...ala m50 swap. avearge do it yourselfer not to mention a crapload of down time.

maybe 15 more horse than a healthy m20 but with more weight. and all up high.

person "b"

european high compression pistons in an m20. still 2.5L but full rebuild

1000 or less...average do it yourselfer. more grunt/power

equal if not more power than a stock m50. still less weight. no headaches.
new/rebuilt engine....is it just to say you have one or is it they are quieter. i am looking for legitimate answers. as i am debating on what to do.

i also dont care about the saying ..the m50 is something to build on later
9/10ths of time the car is r3v'ed or sold before that happens

just curious.

I'm actually going to tell you right now that its alot more down time to take and engine out and rebuild it with high compression pistons than it is to swap an m50.

If you want something with lots of power, stick to your m20, and boost it. Cheap, easy, I'm thinking i should have gone that way... whatever, now i'm boosting an m50.

if you have all the parts and machine shop sourced already how does it take more than 4 days to pull and rebuild an engine? 2 weekends. tops

(i guess if you have to reference the bentley every 2 seconds i could see how.) :roll: ok your boosting the m50. add another 40-80 pounds on the car :?

[screamingbmwe30]

congratulations. you have re-created the mustang GT

right, but see, I have a cabrio- which is 200 pounds heavier anyway (all in the back mind you) so I'm not all that worried about weight with the m50 i figure i'm probably closer to 50/50 now.

As for re-creating the mustang gt- My car isn't that shitty, and I can still leave my friends in the dust in the twisties.

PS Whats with the attitude? chill out.

[screamingbmwe30]

actually ignore my posts alltogether. i am an idiot. really i am

Ok.

A 'streetable', garage-built stroked and bored NA M20 maxes out at about 210-ish whp.
M50- 250-ish whp.

The M50 has much more aftermarket, is MUCH easier to work on, is MUCH smoother, revs higher, get better gas mileage, doesn't fucking tick, ....
I could go on.

The M50 is MUCH easier to work on.

You have obviously never worked on a M50 family head before.

M20's are ALOT more simple to work on, requiring only basic tools for pretty much any job.

Try to disassemble a M50 head without several BMW special tools. You will wind up with 2 snapped cams, and forever incorrect cam timing.

[screamingbmwe30]

thank you jordan. not to mention you have 2x the parts in the head. and brew. i had no idea you could get 250whp from a garage built m50*. thank you for that info :shock: stu's made 235whp. and pete mchenry built it. good to know. looks like i will go with an m50

I have actually, I"m a tech at a BMW Center, Foreign Motors West.

I'm talking about basic maintenance stuff; stuff that the average R3V member can do- oil changes, belts, sensors, etc. The M50 is just all-around easier to work on, in my experience.

[screamingbmwe30]

brew have you been to bmw step? whats your opinion? i thought it was going to be more difficult than this

Floor & Mop tech?

Give most of the members here a M50 serpentine belt, and tell them to install it. No diagram or previous sight of the routing. They will be at it for awhile.

Sensors? Like all the ones under the intake manifold that are all but impossible to reach without pulling the damn manifold? Yeah.. e30's don't have that problem.

Your opinion, valued fairly low.

Not yet. I'm about to start my last year of BMW auto-tech college, and I'm going to STEP next year if I keep my grades and attendance up.

Easy on the sarcasm there killer. OBD1 3.2L can do 250whp, no question. Stu's motor is not really all that "built". Stock 3.0 with headwork, I believe.

[screamingbmwe30]

didnt mean to be sarcastic actually heh sorry. id really like to see some of the dyno graphs. i am more interested in the area under the curve than the peak number. i would LOVE to see m50 dyno graphs. thanks man. im really not trying to be an ass i just suck as a person

[screamingbmwe30]

is the weight that noticeable btw?
