Hello to all my good friend BIMMER LOVER! This is Francisco from the BRONX NY. and i need to know , How can i get more HP from e34 m20 engine? Any tips?

with 172,000 on the clock id be wary of squeezing anything out of it over the normal

its a very open ended question, what would you like us to say? press the secret button under the dash that gives u an axtra 20 hp?
it depends what you have to spend and how daft you are, i mean u can stick a turbo unit on there but then for the cost you could get a bigger say 540 engine from a junkyard..

you dont get anything without spending big money, changing stock components gives you nothing to write home about, like air filters etc

Get an E.A.T.chip!

Yeah, with 172K, i'd say get a lower mileage motor and do a rebuild with some goodies:

Bigger valves
Shrick camshaft
Find a good machinist to lighten up the rotating mass (rods, etc.)
Chip
And a ton of chrome.

Or find an m30 motor from a junkyard.

Unfortunately, ALL of the RD headers ever put up on ebay are for the M20 motor, I can't ever find a set for my M50

At least one of the two of us can put them to use. That'd be a good place to start.

172 aint that bad i have 199k miles on mine and i've been beating the **** out of it for almost 80k, i have headers, eat chip, custom oversized throttle body and airflow meter, bigger/better injectors and a little port work on the intake manifold, all of that crap id say added a good honest 25 hp, i don't buy into the advertized gains for this stuff, sometime in the future i am building a 2.9 stroker motor with all of the trimmings that will probably be good for between 200 and 220, just not sure when it will happen as everytime i get close to pulling the trigger something comes up

Yep. Replace the M20 with a M30!

Have you thought about just selling the entire car and buying a 535 or 540 outright? It would be far less work than swapping, engine, transmission, final drive, wiring looms, etc.
