How much power can be extracted for the M42 ?

[Mystikal]

For what he needs, I vote SR20DET.

If that's what he needs, then I vote he buy a 240sx.

Maybe, they do have quite a few natural qualities that are better than E30's for those who just want to go fast.

Anyways let's not turn this into a "it doesn't belong in there" thread, okay guys?

Sorry, didn't mean to start swinging it that way. However, I do believe that there are BMW products just as inherently intuitive and useful to be able to get good amounts of power and learn stuff in the process. And, obviously, the "largest-amount-of-power-for-least-amount-of-money" argument doesn't need apply here. He has the great chance to do something very unique and fun with his car. I think he should not take the simpler swap route.

I agree more with you GreekDriver. But the M42 still has more tuning easibility than the M20 since it's DOHC. I'd still go for the N/A route with the M42 if you've dedicated that kind of money to modifying your car

I totally agree with you too. A N/A Built M42 would rock my world. I don't think it would be enough power for him though. It would be an awesome track car, not a drag racer.

I would love to have an M42 to build N/A or especially an S14. Hell even an M10, any BMW I-4.

there is a S42 that has 300+ hp. A company in the uk builds them... check out this site

I would like something that will handle on rails and still have the power to run most cars in a straight line.

That is why I suggested a Turbo M20. It is light, and will give you 325rwhp. Something an M50 can't do with alot of money. More than 10,000...

My reason for suggesting the twin cam swap idea was due to the miryad of smog legality issues that I have to deal with here in California. Now granted, when it comes to dealing with this, I'm clearly in the minority. Most states in this country (and countries in the world for that matter) don't adhere to the same stringent air quality standards that California has in place as law. For me turbocharging is not a fiscally wise choice. Spending thousands of dollars on a motor that I know will get me in trouble does not appeal to me one bit. The twin-cam 6 gives a nice boost in performance while not ticking off all the tree hungers around me.

Sorry for getting you all worked up.

The M50 swap is a bad idea.

The 318is is SUPPOSE to be lightweight. With that heavy pig M50, your car would suck. The V8 motor from your Holden Monaro is 100lbs lighter than the M50, more reliable, has alot more potential, has ALOT more stock power(double I think) and gets better gas mileage. You might as well swap that if you are considering putting a twin-cam BMW I-6.

You could also put in an M20 out of a E30 325i, and turbo it. There is plenty of information, and the M20 responds really well to a turbo and can take high boost. It would keep front end weight down, so your handling wouldn't be affected as much as with an M50.

There are very few forced induced 318is E30s out there. So there isnt much information. That would be a harder project. The LS1 swap, would be the hardest though.

Dude, get your shit straight. An M20 turbo would easily way as much as an M50. Calling the M50 a "heavy pig" is just ignorant.

That amount of money could get him a very nicely modded M50. Not everyone wants a 325rwhp monster as a daily driver.

and not every turbo m20 actually works out how people think

And from what I have seen they are all but reliable.

how about and s50 or is it s52 (correct me if i'm wrong)

out of an m coupe, all aluminum block. light wieght, i know its lighter then the m20 but i don't know about the m42

someone shed light on this option for the man.

anyone know the weights of some of the popular engines?

They don't?! :shock: I sure would.

How about the 2.8 liter aluminum Z3 motor? That sounds good to me.

Oh, and BTW, I may be soon selling/parting my M42 w/about 50k miles ('93 motor w/knock sensors):
Schrick cams
JC chip
Head studs (have to look up the brand on these, believe they're ARP)
Supersprint exhaust (won't flow enough with my plans)
K&N intake (like it matters)
Bored out throttle body

If anyone's interested. :)
