im saying he m50 engine sucks ass, its a bad idea to swap it into a e30 when the e30 is just as good

the M50 is better engine... but you can have just as much fun with the M20 and some cheap headers, cam, stroker crank, chip. plus the M20 is very reliable and easy to work on.

objec
01-24-2004, 02:55 PM
just because its newer, and has a bit more power than the 325i m20, it haves more weight and restrictions with the computer, the whole design was shitty,with all that plactic covering shit, thats why they did not stick with it, even the e36 m3 for being an m3 sucked ass, still fast but no multi throttle body system. if your an e30 owner and want to make it go faster, it is not cheaper and better to put a m50 in, a m20 with a little mods will do just as good or better. if some one wanted to drop some cash down for an m50 theyd be better off buying a strokers kit for their m20

if you think putting in a cam is a lot of work and swaping engines isnt, have you ever done either? id rather put a cam in, or a new head. remember 200 dollars what what i am working with, but if some one wants to sell me a m50 for 200, sure

Lennon
01-24-2004, 03:59 PM
Haha, who is this guy? Listen, I was giving my opinion, not telling you what to do, so get down off your high horse and relax. And if you think $200 is going to be enough to do your head and cam swap, by all means, go at it, let me know how far you get.

hahahha! last I checked a rebuilt head was $1,100 cdn, and changing the cam is the easy part but they will run you another $500

well you not a very good shopper, ireland engineering will reground my stock cam for 190, thats gets me 2000 more rpms, and 325i heads sell for around 200 on ebay, motha****a, you should have let me do it for you, i would have saved you money

objec
01-24-2004, 04:42 PM
the 325i head will give an 325e block about 2000 more rpms, right, and the cam will to, thats what i was asking in the begining, what whould be better

objec

as long as the head is sealed good, i think it would keeps its compression, beside that bit od dome space might not matter at all, might help , its a larger space, able to make more compression, and the power come from the design inside the head, right, what different from e and i head, is it the cam, both single, right

Jon@Bimmersport
01-24-2004, 05:13 PM
with changing the head...dont u need to change pistons so they dont hit the valves? because the E has different stroke than the I?

at least its like that with the crv motor and vtec head from the hondas...

What are you talking about? how is a reground cam going to give you 2000 extra rpm on top of the 1600 rpm gain you'll get for the "is" head? that M20 isn't a bmw F1 motor.. it will break appart if you rev over 7500. and have fun with a beat up head off e-bay, your just buying someone elses problem. unless your the luckyest person alive

Oh.. excuse me but only my friends are alloud to call me names like that, so watch your mouth Chicago

Hey guys, since cams are the only things holding us back, why don't we all rev like S2000's?

You have a lot to learn about the internal combustion engine.

Jon@Bimmersport
01-24-2004, 10:41 PM
think about the WHOLE valve train...the cam doesnt open and close the valves, it helps..but there are things called valve springs..and they are being compressed REALLY fast..and only made to be compressed at a max of 5000rpm like on ur E..imagine putting an extra 2000rpm on top of what its supposed to take? i dunno about u...but i think that 1000rpm is really fast..if u think about it...think about how many times valves open and close within 1mins time. now imagine making it go 7x faster..thats whats going to happen, u need to beef everything up..not 1 thing.

maybe ill go add those $35 superchargers i see for sale, ill get the 50% power increase...dont worry, i know its true because they said it is. :rolleyes:

ohh..what M3 do u got btw? why dont u mod that..and keep the 325 as a beater..?

objec
01-24-2004, 11:08 PM
dont worry about my m3, i want to know about the cam or head, did any go to the link, in the e30 section he talks about it, and how he does it, says he regrounds them, to gain up to 2000 rpm

objec
01-24-2004, 11:11 PM
dosent a 325i head rev at like 7000, nd the 324e revs at 5300, how does the i get the extra power, is it the cam?

Jase
01-25-2004, 12:35 AM
i have m20 froma 325i . it dosent rev anywhere near 7500( with problems that is.Only the 4 cyl engines rev that high. One of you guys a re welcome to correct me if I am wrong.:)

I'm 19, does that count?

My 4cy goes to 5500+/-rpm and shuts off, when the engine is at the blue it only does 3-4krpm and shuts off. I find little power above the 4500-5000rpm ranges, wierd :confused:.

listen..here..guys. As he said he can get over 7000rpm he says e36 is crap. he could have had a bit more tact since some of us like the m50. let him ge teh head and lot of HP. Objec you had some guys here that would have offered some good advice but if your going to swear and say stuff is crap expect nothing.even still good luck with your project.

objec
01-25-2004, 07:10 PM
you pussys, if im hurting you feelings then good, if it wasnt for people like me then you would just be chating about the same old crap, i dont want a m50 cause it to much work, and to much money for me. i sarted the thread in the question of which would be a better upgrade a head or a cam, nothing about a m50. if i had the money to buy an engine, i would get a euro 3.6 m5 engine, putting a m50 in is half assing the project.

my 325i can only rev to 6500 and then it hits the rev limiter. the valves dont do anything for stopping the revving of a motor. the only thing you'd have to worry about is floating a valve, which is when the spring cant close the valve fast enough and your piston hits it, this happens a lot on our off road trucks in the deep mud when you really need out in a hurry so you punch the gas as hard as you can. as far as high rpms the motor can handle it, as long as you get racing springs, and aluminun roller rockers for the valves and a racing clutch and flywheel built for the rpms. also the cam is what tells the engine how high to let the motor go, and the distributor. the cam tells the motor when it can make power (rpm range) and the distributor tells it how to advance or retard the spark in those rpm ranges. like my land cruiser had a stock cam, and it would rev to 4200, but now i have an RV cam, now the motor only revs to 3200. but it has over 400 lbs/ft of torque at 1200 rpms! but you cant make the m20 go to those rpms without money. the springs are cheap, the roler rocker are fuc*in expensive. anyway hope this helps.

dude, you have an 800hp e30 and you dont know what to expect from an e and i motor?! i think that you are full of sh%& and that you need to post pics of this awsome e30 or go to school and learn to be a mechanic, because as a mechanic (me) you are wasting my time and time is money, i have tried to be nice but all your stories are BS. this is already got stupid written all over it. anyway the time you are wasting is going to cost you $20. i will send a registered letter to you to collect my money. also if you dont mind stop posting BS. you are not cool, go to a mechanic and let them build you car, because the fact that you have an e30 that should be worth $60,000+ that you and your friend built and cant figure out how to build another race engine out of an engine that is less complicated than the m3 says that you're a fuc*ing moron. you are........JUST STOP POSTING!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

i love that phrase tme is money and money is time.

if you think about it depending upon your job in your case Skunk time is mony for you because you said your a mechanic, which means you get paid by the hour for doing work. where as others of us (myself) don't really get paid for working....

time does not = money and money does not = time. you can get money back but you can't get time back. which is why this thread should be over looked by many of us.

Never mind my confusing post just felt like posting, you can delete if you want.

Didn't read the entire argument but I want to state a few facts.

With my modded to hell m20 2.5i I made 147rwhp/143rwt

With my BONE stock M50 in my E30 I make 162rwhp/159rwt

A 3.0 M20 with mods should put around 200hp to the wheels.

A 2.5 M50 Vano with M3 cams, intake, chip, and exhaust should also put 200 to the wheels. A few people have gotten in the 120-215hp range.

My point? An M50 2.5 Vanos with basic mods will put out more power then a 3.0 m20 modded to hell. Why? The M50 is just a better engine.

There is a reason why anyone who wants serious power yanks the m20.

Want serious power out of the m20? Rebuild it to a low compression 2.8 and add boost.

objec
01-31-2004, 04:16 PM
there are many ways and many things you can do to a car to get power, i still learn new was every day, one would be a fool to think that their car is completed and the max power has been reached, there is always a way to get more power, and from your list above, i say there are alot more (mods) you can do.

Objec ....look for an eta head off an 88 325e, es or 528e. Bore out the cam journal so that you can fit the the seven bearing i cam in the head, do port and polish and you'll probably see a decent gain. If you are looking for more hp than about 15-20 max (with all the add on's , including rrfpr, larger injectors, 325i harness w/ecu wiring and sensors, exhaust, etc, etc, etc) then you would probably be better off looking into the crank from a 524td, 325i head and forced induction. Personally, I have every mod on my 325i that you can think of, I tuned my fuel injection system(runs a little rich), chip, etc, etc, etc, but I still give rubs to heavier cars like the e36 and 46 models. If you do switch over to an M50(blah, blah), you will get more hp, but harnessing it is a different story. My friend has an 36 325i 1995 and I absolutely kill it. From dead stop to high end. Why hp to weight, heavy flywheel, lack of mods. I believe it is a good motor. I am just sick of investing in so called "special tools" to work on motors. And for the M50, you'll need em if you want upgrade cams and install other mods. M20 is simple but practical, but all depends on what you want to do. All I can tell you is that the piston config on the e and i models are different(from seeing them and working on the motors) I has a pop top, e doesn't. What ever you feel inclined to do, do it, because it will be a learning experience for you. Hope all goes well. Latz Jimmyd
