turbo M42??

[ChItalian1027]

ok i know this is a stupid question but some guy on bimmerforums is planning on turboing his M42 is it possibly and can the M42 take that kind of pressure?? the guys name is 95Compact http://forums.bimmerforums.com/forum...d.php?t=701296 i don't know if i told him correctly but i said that turbos would hurt the M42 but i don't really know!! also i told him that the DASC was a better choose seeing as others on this forum have them. i dunno i think i screwed up by telling him the my opinion!

It's best to let people do thier own thing, this is how progress is made.

General rule of thumb: If you don't know what you are talking about, don't say anything at all.

When are you supercharging yours? From what i read, the m42 engine has forged internals so im guessing it could handle the turbo right? Then Redis blew 3 engines i think, but not sure what engine they were.

They are m42. I have a 93 coupe that now has a 94 m42. my water pump went out so i overheated one. I have also boost spiked at 15 lbs. I just got my turbo back so I am going in for a tune in a couple weeks.

turbos are fine on the m42.

Turbo's are more than fine... At this point for a track car I would take a turbo over a supercharger any day. Mainly because it is much easier to control and maintain lower temps with a turbo charger. You also don't have the parasitic drag associated with the supercharger... The DASC is fine for a daily driver, but if I'm going to be out running 30 minute sessions at 5k+ rpm I'd want either a twin screw SC, or a turbo charger. The OP in that other thread is absolutely correct though, 8PSI is 8PSI. And since you can do a custom intercooler for a turbo for a lot less than what it would cost to do it for the DASC the turbo could be considered a better solution.

To me, the major benefit of the DASC is that a lot of people run them, and I've not heard of anybody having any problems with them other than 1 person who detonated his engine by running a 10-12psi pulley and running the car on the track. And you have a major fabrication shop backing up the product.

The intake manifold and turbo manifold that 666 has looks incredible. There is a guy on BFC building an turbo M42 mod class race car using the 666 components and it looks sick. He is hoping to put down comparable power to a built s14. So I figure he is shooting for 275HP.

Yea verily, howstuffworks.com rocketh mightily!

But, don't forget that Google is your friend.

Wikipedia is quite useful too.

Reference.com even has relevant info.

Turbo is better than a supercharger any day in my opinion. It doesn't have the parasitic loss that a supercharger has. In response to the question will it handle it, sure it will. You could go all out and spend a bunch of money on a turbo and it will make a ton of power. It depends all on what you want and how much you want to spend.

I agree. Buy the supercharger is you want reliable power. It's not insane power, but it IS reliable.

For big power, get a turbo and go wild.
