Boost Brothers manifold mounted in my 2002!

Yes, the first official mounting of a Boost Brothers manifold in an '02. I'll keep the details short and sweet so we can move on to the pictures.

I thought I would be the guinea pig for this mani because it was released at the exact same time I needed one. Having seen the pictures that Hapgilmore posted up, I thought for sure the flange would be way to far forward and I was prepared to cut into the front end. My suspicion was correct, but I would have to cut into the front end to run the charge pipes anyway so it's not a big deal. All in all, I believe the manifold will serve its duty very nicely and I don't forsee any issues with it, although I think a support brace would be a good idea.

Keep in mind I have a small turbine housing on there right now for the break in period of my engine. A larger housing will move the turbo at least a half inch toward the engine.

Specs of engine:

2.1L M10 with e12 head

Ross 91.5mm forged pistons, 8.5:1 comp

Ireland Engineering race bearings

MSIIv3 with EDIS

318i intake with 58mm TB for now

and a shiny Greddy BOV

On to the pics...

It does not interfere with the chain tensioner. About 1/8" clearance.

The compressor housing will end up being clocked so it's pointing nearly straight down...

Nice!

What is your HP objective? How did you size your intercooler, and how did you determine fitment?

Please post more pics as you progress!

Well I'm not too sure but I figure if JRCook can make 240hp on tuned K-Jet and 14psi, I should be able to get close to that after I can produce that much boost with my turbo. It's been said that I should only run about 12psi with this small snail.

As for the intercooler, I have forgotten the dimension of it but it is a bar and plate type just small enough to not interfere with the hood hinge supports or anything else. I bought it off of the same guy I bought my short block from so I didn't pick it out. I'll measure it today or tomorrow.

humm, 240hp with 14 psi is almost mathematicaly impossible, unless the poor venerable M10 has 4 valves per cylinder and over 80% eff.

70% eff. is a very efficient engine already, fully ported and flow matched with a 100% efficient intercooler.

14 psi non intercooled of M10 power gets you around 200hp no more.

once intercooled (properly), and the timing adjusted accordingly (important) expect 220-230hp maximum. this is purely mathematical related to thermodynamics.

My intercooler is in the range of 95-100% eff. Last g-tech runs with 16psi suggested 260hp, that also suggest 70% eff. engine, wich is on the very high mark, only because of the intercooler efficiency.

Did you remove the support brackets that the stock horns mount on?

I imagine that you're planning on keeping the stock fan. It doesn't look like you'll be able to mount an electric pusher in front of the intercooler.

I'm wondering if the intercooler came from Bell Intercoolers. They have a pretty wide range of standard sizes available.

Looking forward to your measurements. the height, length and width of the core is sufficient for me.

Thanks!

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
