You should find it very useful...

I realide that my engin is a M10 and yours is either M42 or M44 (same diff I say) but do you think any of this would hold true for my 18-21 year old motor.

I thought the M42 was not the prefered motor to place a supercharger/turbocharger onto because of knocking, pinging, and possiblity detonation (or explotion), or is it certain years of the M42 are ok for FI.

ADD: Did anyone mintion a AMF/MAF swap any increase? I believe that if BMWs were equipped with the same intake design as the one on Supra's with a shield there would be a slightly noticable increase in power (minus the location because of water, snow, sleet, ice, etc.).

I'm not too familiar with the M10 motor. I just know it once produced an awesome 1200HP in a '83 formula 1 car. I know the M10 motor is very strong indeed. What's the compression ratio of the M10? The M42 is 10.5:1 I think, I forget.

Anyways, there is a popular supercharger kit for the M42/M44 which produces 175RWHP and it runs at around 7-8psi which is relatively low. This uses the Eaton blower with a kit designed by Downing Atlanta. It's true the M42 doens't like to be turbocharged. I've heard from people who have turbocharged the motor have run into a lot of problems.

The M42 motor was made to be revved. It's been used on the race track in BTCC for 3 years. It was the 2.0L S42 they called it, which was just a highly tunned M42 motor. Just before that they were using the S14 motor in their E36 chassis.

After reading some articles, I read that the M42 motor's technology was based on the 850 motor, I don't know how true this is, but that's what I read. I think the M10 and M42 motors are really quite different.

There was a long discussion about that MAF, it would seem it's a huge restriction on the M42 motor. A lot of people were talking about having custom ones made.

Fuel comsumption has dropped I have noticed. I would say it has almost doubled, but if gas in your area is cheaply priced who cares. I wouold say my sad 0-60 time has gone from 11sec I believe they say to 8-10secs (human counting here).

One more thing your engine will get a little hotter, which might be good for those of you drive your car likes its a M3, meaning you hit 5000+rpm freqeuntly. Moreover, the heater get hotter too.

fuse swaping for higher ratet one ?

Quote:
Here's something that hasn't been posted yet. Switch out the (15 amp brown) fuel delivery fuse (9) in your fuse box for a higher rated one.
It is ok during winter but in hot weather the wiring might melt
because of higher amps going

but hey this is chipest mod i ever heard

Knocking, pinging, and detonation has nothing to do with the engine itself. If the fuel delivery is not properly tuned any engine will ping, knock, and eventually melt a piston or two.

Moreover, m42 is a very good engine to turbo/supercharge because it has a forged crank. All you need is some low compression pistons and a couple more internal items here and there. Then 250rwh is easily archivable.
