Super/Turbocharger questions

[Bluebimma]

Theres no reason for the "/discussion" at the end of your post, thats why this is a forum. I gave the OP simple advice that has been given many times before as well as stickied in the FI section. Also, ive heard of people blowing their engines on DASCs so its not like its impossible or never happens. Custom turbo setup take more knowledge, maintenance, and care than a bolt on bolt on supercharger, its as simple as that. Whether turboing the m42/4 has been a failure by few or many, doesnt mean its impossible nor does it mean your engine will blow just because you have a turbo on it. All boost applications put wear and tear on power/drivetrain as well as the rest of the car, just make sure youre aware of that and choose accordingly.

Its crazy how someone with a 1.6 honda can run a turbo set up and never blow his car up but if you do it to a much stronger larger bmw motor that it will blow the car up. Maybe that makes honda a much better car? IDK
Maybe DASC is the way to go if you would like to play it safe but turbo your car if that is what you are looking for. DASC is what is the fave because that is whats avalible to us but that should not stop you from doing a turbo kit just make sure you know what your doing .

Sorry, no offense intended. I'm just sick of this argument, it's ridiculous.

The m42/m44 can't handle boost spikes. Superchargers don't have boost spikes, turbos CAN. It seems like the obvious choice is the one that won't spike and break your internals. Sure a properly designed turbo system can be safe, but be realistic, if the OP was capable of designing a turbo system and tuning it correctly do you think he'd be asking 318ti.org about it? There are few people in the world that can FI tune a OBD2 BMW DME, I bet the OP isn't one of them. (no offense)

There are ZERO turbo kits on the market that actually produce any power. There is only ONE supercharger kit on the market that is tested and proven to be a solid performer.

I don't know how this is even an arguable point.

"I bet the OP isn't one of them. (no offense)"

None taken. I'll admit, I know next to nothing about FI and am learning a little at a time. I will be content with hp gains anywhere from 170-200. The main reason I am going with the DASC is because it's made for the BMW 1.9 liter engine and it comes in a kit with all the installation hardware. I do appreciate the help.

Would the KO Performance supercharger ware the engine down more than the DASC?

....

Last I read that's not a great path to go down. (KO Performance that is)

Stay away from KO. JUNK!

[dogcrapau]

in regards to Blown engines with DASC, what type of engine were they and why>? If i DASC an automatic stock and remain stock, and gun the car, will it blow the engine? (newbie)

I wouldn't say people here are not capable. The main issue is time, money, and motivation. I don't have enough of any of those to be applied towards designing a turbo system for my car. Likely, neither do most people here. That's why we ask these questions.

DustenT, I know this stuff can get. . .repetitive . . . but that's why you leave it to the newer members to answer these questions and talk it to death. We haven't gotten tired of it yet. Also, nobody goes to build a turbo just because someone on a forum said it was a good idea. Believe me, either you are already driven to do something like this or you have tangible evidence of a working setup. Hearsay is never enough to justify potentially doing that much damage to our cars. We love our ti's too much!

If you guys have a chance check out the azavedo motorsports website the have a nasty TI that is turbo that the guy who owns the shop uses often i have seen it in my stop and shop parking lot... That is where i am takeing my car to get turbo charged. It is gonna cost me about the same as a DASC and they give me a warrenty on all parts as well as my engine so i think if you go to the correct place it can be done... ill keep you posted on my car

One of those guys used to post here. I think their turbo experience is with the S52 motor though.

I think the main reason this hasn't been done is money--it's just not good value to turbo the M42/44. With what you would be spending to get a proper setup, you could do a swap or a blueprinted motor.

The issue generally isn't if it can or can't be done, but how much it will cost.

Correct, that's a turbo s52, much easier to do than the m42/m44.

There is a turbo m42 E30 running in club racing that is putting down well over 225hp... He used the 666 turbo manifold and did a lot of custom stuff along with running stand alone engine management... Tuning is key, and there are a limited number of shops that can do a custom tune on a Bosch DME... If you go with a stand alone you can find plenty of people that can tune it as more people are familiar with how to do that...

The only bad thing is that a stand alone, other the MS, costs about what the DASC costs.
