TURBO?!?!

[chuckrussell]

So yeah...I'm sure we have all noticed the supreme lack in the market for a viable turbo manifold for these queer (as in weird) 4 cyl. engines

There are all sorts of turbo kits avail. for the l6 engine but almost none for an l4..because no one makes the manifold.

So I am taking it upon myself to make my own. Unless of course any of you have taken the 6 cyl. maniflod, and just like, chopped 2 cylenders off?

something like

and just cut off the last two cylenders. ater spending a few hours in my engine bay, i assume it will probally fit all the same. But i am wondering if anyone has done it or experienced complications

put a supercharger

Search the forum on this topic. The reason nobody makes a manifold is because nobody would buy it. Every turbo m44 on this forum has blown up. NO FORGED INTERNALS = WEAKNESS.

I was considering the DASC, but I really want the turbo. And I have read through the threads about the lack of forged internals. Sounds like I need some new pistons, and a polished head. Maybe lifters and a new camshaft, but all in all, I really would rather try something that hasn't been done quite that often. I'm not just going to do something half a$sed...But to the real question, is chopping off the two cylenders a possibility or am I going to have to get a custom manifold made?

Plus, who doesn't like the feel of a good turbo lag?

Thanks for the input and helpful advice guys, and keep it coming

I havent researched it, but doesnt the manifold from the TDS in europe work?

m42 turbo manifold from 666 plus a lot of other work. Putting down 283rwhp at 15psi on the first dyno runs... Must be a blast to drive...

And I'm sure it cost a lot more than 800$ and didn't use junk yard parts.

I think that I'll buy neukin manifold from turbogoods for 615$, with a t25 flange and internal wastegate, then I'll need a great turbo for 220-240bhp, without too much lag and fast spool time.

I have doubts between GT25R and GT28R...

I don't want to go over 250hp in the future, so the GT25R is rated for 270hp.. will GT25R have faster spooling time and at low revs than GT28R at same boost and our engines?

thank you

make a manifold

your stock header is tubular, so you already have a flange to go from, or order a flange for a m50 and cut it

i also thought about cutting 2 runners off the 6cyl manifold, i guess someone has already tried it not sure how it went.


so does the m44 have differnt internals then the m42? i have an m42 92 318i and i thought it did have forged internals


supercharger = weaksauce
theres a reason no one really supercharges 4 cyl motors, not sure exactly what it is haha but i HAVE had a jackson racing SC on a 4cyl and it was bogus. later turboed the car, much better.

people that talk about they like the smooth power of a s/c or "feels like stock" are pussys. sorry.

from my little reasearch, it looks like it has totally differnt bolt patterns

unless it just uses less bolts. it has a '. '. '. '. pattern not a :: :: :: ::

The issue on both motors is the crank... The crank in the m42 or m44 isn't going to hold up to a lot of power as neither one is forged. You need to get a forged crank out of a bmw diesel motor.

What is it with the people coming onto this site and attacking people? I guess the pussy's on this site that are running around 10 psi through the superchargers safely will laugh when you blow up your m42 trying to rig it ricer style.

[7808]

10psi gets you what? 200whp on a dyno jet?

I might be getting my buddies 330ti AKA m3Ti this month for 7-8grand...he is on here every now and then. I sooooooo want it!

This isn't bimmerforums. If you want to have an intelligent discussion, feel free to stay here. If you feel the need to insult members on this forum, please leave and forget to come back. It's not wise to insult the small population of m42/m44 owners that are running boost when you clearly need our help.

The SC vs. Turbo argument is lame. It's obvious which way is safest and the most proven. There is no need to try to convince this forum otherwise, since you have absolute zero data to back it up.

Let's keep the discussion polite please.

kthxbye

[chuckrussell]

this wasn't actually inteded to be a turbo vs. super argument. Clearly super wins in both departments, but I was more of asking for help i suppose.

Eh, no matter as I cannot get my car to stop over heating anyways haha. Sound like a great time to take apart my car and replace those internals
