Is the gauge adjustable?
That value of 14.7...is that a standard?

Thanks!

no the gauge isnt adjustable and a narrowband wont tell you your exact afr, it jist gives you an idea if your lean or rich. A wideband will tell you your exact afr. 14.7 is the afr that after combustion there is no oxygen and no fuel left so your neither lean or rich, its a stoichiometric afr.

What kind of machining was required on the M44 crank? Are you using the balancer from the M44 as well? When i look on RealOEM.com, it appears the nose of the crank is quite a bit different.. Also, what about CrankPosition Sensor, are you using the front like M42, or the rear like M44? Thanks so much!

I didn't notice this post till now, no machining was required for the m44 crank, but the crank mounted trigger wheel was removed and the crank required quite a bit of weight to balance it

you mean weight was added back to the crank? or removed?

have you had it on a dyno? what's the ass dyno say?

i'm basically gathering and building the same engine you have, picking up my 5/95 build m42 in a week

$350 w/118k miles on it, 318ti owner swapping to 6 cylinders.

You still running the stock cams?

Weight was added to the crank, last time i dyno'd it made a bit over 180 but alot had been done since the build, wild cams, different head, steel multi-layered head gasket, different exhaust, was running ms2 for a but now its on a custom eprom, hopefully soon it will have a WAR chip

Are you running the stock spark plugs? if not, do you have p/n for colder plugs? how wild of cams? what's the idle like? webcamshafts.com? how much porting of the head?

i'm thinking i will not try to squeeze too much out of this engine, and revamp the engine that's currently in the car for turbo on MS.

I am not sure what plugs are in it, i bought 16 plugs total in 4 different ranges, cams are catcams the wildest ones they have for hydraulic lifters, at idle it cams its ass off if i set it low. for porting, I mainly smoothed out the ports and port matched the intake to the head and the upper to the lower, and ported the throttle body then polished everything. I would not reccomend my cams for a turbo build, they have too much overlap, you may need to have someone make some to your own spec.

Which Aeromotive FPR did you end up going with? I am starting to suspect that my FPR is causing trouble, so I may as well put something adjustable in.

Also, are you still running the stock fuel pump?

sounds like you car has come along way from the original upgrade. Would be good to see an updated dyno run

1991 E30 M42 · « **Reply #86 on:** April 13, 2010, 09:31:37 AM »

I dont know where my printout went but if i find it ill post it. My next step is a turbo build, and when I say turbo build i mean not a budget build, It will be done right I just have to track down the turbo I want and find a decent price on an AEM

e30guydownunder · « **Reply #87 on:** April 15, 2010, 05:49:03 PM »

Sounds Good...I know about doing it right, probably the only issue I have is my tiny turbo

So I am avoiding at all cost the epic..."Uze teh serch button Noob" response by everyone while still getting more info, hence the 2 year old bump.
anyways...
Is this motor still running strong? Ive just bought another m42 motor and was planning on starting something like this. I know everyone really likes the m47 crank idea but i really dont think thats what im going for. I like the m44 crank idea with s50/52 pistons.
My goal isnt a certain number as far as horsepower...really i could care less i just know i want it to be a little faster. I plan on spending more time with the head to get better response.
My dad always taught me there is a difference in a fast car and a quick car. After several hpde and other track events im learning to appreciate this. Ive decided...i dont want a fast car...I want a quick car and thats why i picked the 318 over the I6 motors. Let me know your guys' thoughts and chime in if you have any advice.

thanks

Also in all my countless hours of forums searching i found this link to be of some use and added it to my favorites. Its a stupid personal thing i guess but i like the thought of having a 2.0 Liter. I have owned an ungodly amount of prelude all of which were 2 liter. Just seems like the right thing to do lol.

The M44 crank is a great option for those of us in the US who do not have access to the M47 stuff at decent prices. Alsothe M47 crank gives a less desirable rod ratio.

If I had my engine torn down, I would source a M44 crank to put in it.
