What did you do with the internal waste gate? I'm concerned that if I leave it in, it will become permanently fused and if I remove it, I'll never get a proper replacement.

Thanks!

i dont see why it would become fused though, isnt that stuff basically high tech powdercoat? you could just remove the actuator arm and flapper, then weld it on later. The fit on those things is pretty sloppy anyways. I'd say try it. You can always weld up the hole and go to an external wastegate. -Reid

it wouldn't be that hard to get the alignment right again, especially since I could change the arm length of the actuator.

Does yours leak much around the shaft that works the waste-gate? A T3 Garrett (at least with the exhaust adapter I have, doesn't lend itself easily to an external waste-gate. I'm keeping my 9.5:1 pistons, so I don't need all that much boost to make a monster.

Thanks!

but what doesn't. Hardly,just a bit black around the whole. What exhaust adaptor are you using? A volvo 740 turbo unit or a saab 900 turbo both seem to be pretty good. I see them welded up a lot, the flapper is just kind of welded there. I used to have one, no idea where it is now. How much boost do you plan on running? I run 10-12 pounds with flat tops. -Reid

unit. I'm going to first go to EFI / NA and sort everything out. I got a good deal on a dodge Shelby intercooler.

The output flange is a 45o elbow with a two bolt flange. It's the type that takes a metal "O" like an 02 exhaust system.

Anyway, I'm planning only on 5-6 lbs until the the ion sensing ignition that's in the works becomes available. With a stock disti and complete programmability over the squirt (and a WB-O2 sensor), I should be able to keep myself nice, rich and cool.

Once I get an ignition control that will give me maximum advance all the time, I'm going to go to 10 and see how many differentials I can break.

Cheers!!

    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
