the e12 m30b28 intake manifold for boosted m30b34/35 engines

RED89E34 · Post by **RED89E34** » Jan 12, 2012 7:48 PM

Has any tuner thought of using the intake manifold from the m30b28 engine, particularly a 1978 my 530i for a boosted m30b34/35 engine?

Intake visually looks smaller in runner length and overall volume but the manifold looks cool and not like trapezoid.

And it uses an awful fuel injector design that will not be useful to anyone.

With some work you can install newer injectors.

There are E12 turbos out there. No reason you can't use the intake if you are willing to work at it.

Actually I think 533i injectors are 528i injectors with orings instead of hoses. They all seem like pintle injectors.

Oh, it's the hoses you don't like?

Agree 100%.

I think I will pick it up and just stare at it for a while.

Yeah the securing of the injectors is strange.

I will have another look at the hoses that you all mentioned.

Thanks for the feedback.

dont really understand using a manifold that makes no gain and is a pain in the ass the make it work with normal injectors. Are you trying to go for the look???

I'm guessing the hood doesnt close....

But I like that setup- I just require my hood to close and look stock when it is.

That is an E12 engine bay and the hood does close. That car is a monster and immaculate throughout.

Is that Zane Coker's E12?

Yep, I wonder what's up with him and the car?

I have often wondered that, too.

Do you guys remember the great story he wrote up about driving home from 5erFest in Chattenooga? Something about destroying some dude with a hemi and over-boosting?

I have heard nothing since 5er Fest. Wonder if he went another direction? That car is/was bad ass.

Looks yes but overall I would like better access, removal/install.

Isn't that manifold better for top end? I thought I read Paul B. explaining the differences in the manifolds.

Shadow · Post by **Shadow** » Jan 14, 2012 2:09 AM

That picture takes me back in time to an early 90's car show.

All it needs is the hood to open up like gul wings.

It's easy to use large body, o-ring injectors with the e12 manifold. You can use the stock e12 rubber mounts and hold downs with the injectors clipped to a b34/b35 rail. This is what I have on my Bavaria. The FPR needs to be facing the firewall though.

I need some help with the above. We need to talk next week when I pull rocker shafts.

I've done it before. It isn't difficult. You need to bore the manifolds to clear the pintle caps or retrofit the old style pintle caps. Also, check this action out:

This is from that Alpina turbo E24 thread. Gives you an idea of what they did. Notice they used BMW injector manis and then just made their own upper mani.

I've got a milling machine and a spare set of injector manifolds if you need assistance, but it can be done with a drill and a guide bushing.

Is that an M106 fuel rail?

I think I need to send you a set to machine.

I recently picked up one these manifolds & am considering the mod. Can anyone comment on gains to be had or direct to a thread that has this info?

Hey Guys,

Still around and still have the black car and it still runs great. I have not showed it much or done much of anything other than drive it around on weekends to keep things fresh, even thinking of selling it. I got onto a slippery slope with a Porsche 930 turbo slantnose, acquired a few years ago, now at 2600lbs and 500hp, it rips ass like no other. And I thought engine building was easy! Never touch one of these things! But when done, they are very sick cars that takes much nerve to hang on to and not black out....else kill yourself. I was even thinking of getting a Fla. tag which says "WIDMKR" for widow-maker. haha Anyhow, thanks for all the memories and glad you guys think of me or my car often. You guys are great!

My email is: nastroma@comcast.net

I'll help anyone with advice, knowledge or what have you.

Paul, what's your turn around time in doing a set of these?
Thanks!

I have a set of manifolds. I can make a jig and then the turnaround would be really quick. This weekend is booked, but I can probably crank out the jig next weekend. Do either of you know if the B35 fuel rail has the same mounting points as the B34 rail?

They're the same, save for the b34 has 4 mounting points, the b35 has 3.

I have an extra B35 fuel rail that I can ship to you if you need it, Paul.
