Damn.

Looks like im going to have tons of room with no coils, no plug wires/wire sheilds, or air conditioning. Hell, I dont even have to keep the impact sensors for the SRS system now that I no longer have an airbag.

are you just straight up making it a track rat?

Nah, I just havnt had my A/C belt on for about 2 years now and havnt missed it a bit, not to mention that its still R12. So there's my reasoning for no A/C.

Coil on plug... well its 160 for just new wires so i figured my coil on plug setup for 130 bucks was a good investment and cleaned up the engine bay.

My Mtech2 wheel deleted my airbag so I mine as well get rid of all the impact sensors. You do know how dangerous our airbags are correct?

So no, I wouldnt consider my car a "track rat" because its never been on the track. More like a tastefully moded bmw technicians daily driver.

I've got an Mtech 2 wheel for that very reason my friend.

I'm happy that the p/o of my car converted the system to r134a...i bought two bottles of that stuff yesterday and now it blows ICE cold!!! $20 a bottle and another $11 for the pressure reader.

back to the manifold thing I would deffiently would be interested in the stock manifold fliped just need to know a price and where to send the cash also what kind of turbo can you run on this manifold does it have to be a specific turbo or can it pretty much be any one?

I plan on doing the stock flipped. It shouldn't be too much but I don't have a ballpark for anyone yet. More than likely the manifold will be for a t3/t4 setup but since I will be having them made I prob can have like a holset or something else welded on instead.

Basically if this works out the way I have it planned right now, you will send a manifold to me and I will have it flipped and modded for your turbo and external or internal wastegate. And then I ship it back to you. So basically you are only paying for shipping and labor not materials, since we will be using the pipes from the stock manifold.

sweet!!!! keep us posted I am not trying to go real huge with a turbo just would like a few extra pony's under the hood

I've never heard anything about the air bags. What's the deal? Sorry about the off topic post.
As to manifolds, cracked welds every year seems a bit much. Sounds like a fabbed to spec stainless with some support to the block maybe the way to go from a reliability standpoint. Sometimes the more expensive one is cheaper in the long run. True if you're redoing a flipped stock header every year.
"Cheap at any price!" has two meanings and both probably apply here.

asubimmer · « **Reply #23 on:** July 04, 2006, 11:35:28 PM »

Well I am 5'8" and 140lbs and the 1st gen airbag was designed for someone like 6'5" and 250lbs IIRC, which = certain death if it goes off on me.

The guy I am having weld up my manifold is plain AWSOME. I really doubt there are going to be any problems w/ the manifold. I can even have a support welded on also to help support the weight of the turbo if it will help everyone sleep at night

I was actually considering it anyway.

what are you planing to do about the engine management with your turbo? I wonder if it would be possible to use a maf like bmwmans and some bigger injetors and have it running well?

bmwman91 · « **Reply #25 on:** July 05, 2006, 09:55:25 AM »

Fuel is only half the battle with a boosted setup. The ignition timing would need to be adjsuted for the new air flow. You would likely have some difficulty going FI and using a performance chip of any type on the M42 as the performance chips get the power gains from more radical ignition timing. It has been rumored that the stock chip should be OK under 10psi boost, but I would be really careful above 6psi.

Fueling can be taken care of with a simple mechanical FMU or an A-FPR + injectors (not the RIGHT way to do it, but it CAN work). Ignition timing on a modern engine like this is not as easy, at all. So, anyone wish they were running a dizzy like the M20 guys? Just turn that cap back a few degrees...problem solved. Lol.

well if i do turbo i will probably get the e36 computer and harness

bmwman91 · « **Reply #27 on:** July 05, 2006, 11:34:34 AM »

Yeah, I suppose knock sensors would be of some help

. The E36 uses the DISA manifold though, so I would imagine that the ECU is programmed to deal with:
a) controlling it
b) is tuned for the two distinctly different running modes. The fuel and spark maps are likely quite different than ours (with pieces of maps for the two different intake states...determined by RPM I believe).

There may even be feedback to the ECU to tell it if the internal flap has malfunctioned, so it may 'freak out' if there is not a flap connected at all.

Being tuned for the E36 manifold, just getting it running drivably with an E30 manifold (no turbo even) would be interesting. If you actually do try this, keep us posted. For your sake I hope am wrong if you do all that work! Maybe by then I will have finished cracking the 175 EPROM and some tuning can be played with.

the knock sensor thing is just a load of poo...

Don't get me wrong they would help but they are in no way necessary. There are TONS of ways to reduce knock (ie detonation) these days. No knock sensors = no problem.

bmwman91 · « **Reply #29 on:** July 05, 2006, 02:08:26 PM »

I do agree about the knock sensors. If it is tuned right you do not need them. They CAN be useful in doing the tuning though. You cannot always hear ALL knock with a loud exhaust and rough road/noisy car though.
