can the air flow meter e30 and e30 m3 be taken out some how? and the car still preforms as good or better.

Your a moron, you need that sensor for the engine to run.

You can take it out, but you need something else besides the stock ECU to control the A/F ratio. Either a stand alone engine management sytem, or just the stand alone fuel management. A couple people use the megasquirt, with a map sensor for the most affordable route. You can't just take out the AFM, and be all said and done, and have your car work fine if that was the case no one on this board would have an AFM in there car.

if the afm is not there it wont start.

Your a moron hahahahahahaha:D

anywqays...the car can start with out the AFM, you can't run you r bimmer with out a AFM...you can swappa bigger AFM from the M30 engine and swapp also the electronic part inside the meter....as I did it and many other guys did it!

what kinda of exhaust manifold you you have, is it custom.
how much psi do you run, do you have a bov, how does the manual boost control thing work on yours.

is it better to put your afm where you have it or inbetween the air filter and turbo?

why does evryone give objec a hard time?

anyway i don't think your car would run.

changin oil one day forgot to reattach and secure the sensor car would start but just barely. it run for three seconds then shutdown. tryed starting and taping the throttle. i pushed the throttle one inch and my RPMs went to 6k easily.

Actually you can completely bypass the AFM, but it would require you to completely reconfigure EFI system, including a new ECU, FMU, Sensors, etc. The system requires you to replace you crank pulse sensor, with a four sensor crank pulse system. I will try to get the info to you. Everything runs about $1500, but you supposedly gain somewhere between 15-30 hp. It would be far easier and cheaper to run a plug in MAF . You can get them from Pro-M and Split Second. They run between $700 and $1000. You make the call.

You should read some of his other posts...thats why everyone gives him a hard time, cuz he's full of $hi#.... He already has an 800hp e30 M3 twin turbo:confused: and his non turbo e30 325e already has 250hp:confused:

see here..--->My Custom Turbo Header (http://www.maxbimmer.com/forums/showthread.php?s=&threadid=28609)

I went that route cuz I thought it will be more accurate in metering the flow rate...you can put the AFM before too, but I don't know how it will respond...some puts before and other after...maybe is not much difference, dunno :confused:

aslo diegom6, do you use a bov, on you turbo system, and how much more boost did that manual boost thing give you.

you cannot, they have different volt siganls..won't work..I tried it...I will do it again once my SMT6 is done and then tune it...yuo have to look at soem type of device that allows you mod the siganl, and then will work

what do you use to measure your psi?
what type of boost gauge?
how would your car run if you did not have he bov? and how is the bov connected to the turbo? where does it fit in at

I got all that no problem! ..i used aluminum intercoolers and welded them to the steel frame of the car.. then i hot glued the quad turbo down pipes together.. you gotta re-glue it once in a while but it sounds amazing when im doing laps in my living room.

Rays is good.. they built my 1500 hp Enzo Farrari..

running the AFM on the compressor side of turbo will not allow the car to start. I tried this when assembling the turbo ETA that i did.

It would crank but not fire. Took off the charge pipe that went to the TB and we saw raw gas coming up through the pipes.

no good.

Put the AFM back to the stock location, havent had a prob since.

Dont bother moving the AFM, but do as diegom6 did and upgrade the AFM internals.

yes i own it and it tells everything that you need to know, but the book is general and you have to study engines to know exactly what it is saying. not saying you have to study engines, but you have to apply the knowledge to your specific engine(s). but the funny thing is, that it explains how to make real turbo engine, not fake ones. real ones like slowered's 550 hp 318, it even has ray's make believe shop in chicago mentioned in the footnotes.

The Corky Bell Book is great. I invested in the supercharger book that he wrote as well. Unfortunately, I have neither the time, nor the patience to work on a turbo system right now. My dream has always been to keep the stock 2.5L M20, bore the crank journals to fit an EVO 3.2 Crank(trust me it has been done), run a CR of 7.8 to 8.3 and either run Vortech Supercharger w/ about 8 lbs of boost max, so I could possibly retain the stock ECU. Just a dream though.

jimmyd1
02-12-2004, 07:35 AM
Sorry about the "either" in the last post, the other option would be to run T03/04 or a T60. I have spoken w/ Pat P several times regarding his forced induction garage. From what I can gather, it takes money, time and patience, two thing of which I do not possess*mumble*

Skunk#1
02-12-2004, 11:21 PM
i need to go to walmart and buy some time and patients. do you have any info on putting an evo crank into an m20, what does that make it, a 3.0L? that is what i want to do, then turbo the motor, i am saving for the 3.0L kit that ireland engineering has as we speak.

jimmyd1
02-12-2004, 11:57 PM
The 3.0L Ireland crank has been milled to be a direct fit. Apperantly all that needs to be done is a 1mm overbore of the cyclinder bores. The 3.2 is a little more complicated. .33 mm overbore required on the crank journals and a modified sump. Also need to do a 1mm overbore on the cylinder bores. The reason why I was going to go the 3.2 route is that I have a friend that works for Zeiss in Munich and he works very closely with the engineers from the BMW plant there. I was told by him that he could pick the crank up for me for about $1300 US. At this point, I just do not have the time to be pulling the engine out of the car and doing a complete bottom end rebuild. I was also considering the turbo idea with this setup and figured the displacement out to 3.1 L following the overbore and installation of the crank. I figured this would be the less expensive route to achieve 300 rwhp. When I finished adding everything up I think I came out with a real $ figure of $4900 for everything, including the turbo setup(everything bought individually).

02-13-2004, 11:12 PM
Objec,

I'm not sure where you live but here in NZ we can get a decent aftermarket ECU for around $1000 kiwi dollars = $700 ish USD. This will replace the AFM with a MAP sensor (you'll need a 2 bar map sensor for boost) MAP is manifold air pressure which is measured by a small rubber device that gets depressed in. The AFM in your car is the flap type device, you can replace it with different kinds of AFMs like a heated wire, this one is much less restrictive. You will however need to modify the signal for your motronic/l-jet ecu to understand it.

The BOV is for when you let your foot off the gas, since the turbo is blowing out a bunch of air and the throttle body is closed it would mean the turbo would stop/slow down very quickly which is not very helpful. The BOV opens and vents the boost to atmosphere and allows the turbo to keep spinning.

If you want to learn more about turbos and how they work get Maximum Boost as people have suggested, a turbo needs to be matched to the motor in terms of exhaust gas, intake flows etc.

Good luck.

BladeRunner
02-14-2004, 02:22 AM
so from what you said nzer the large the BOV the louder and free it flows. This may inturn result in a little less turbo lag?

Jase
02-14-2004, 02:33 AM
What is a safe boost for a stock internals m20/m50 8psi?.
Thought i would ask as I have access to a vortech S/C

89325iturbo
02-14-2004, 02:50 AM
Yes having a BOV will help reduce some lag, in between shifts, or if you get of throttle and back on it quickly. You have to have a BOV that right for your cars psi level. Most are adjustable so its not a big deal. To soft, and it can open early, or to hard and it might not open enough. The sound a BOV makes has no difference on how it works. Different makers have there signature sound. I can't say for the M50, but 8psi is fine for stock internals on the M20, i say you can go higher then that without much worries. Im sure the M50 would be fine at 8psi also.

Skunk#1
