    Just too common too pedestrian I don't like the quality or what they try to sell them as. I don't like that everyone who owns one thinks they are perfection. I don't like how they look. I think they are poorly engineered... I hate that they are designed for looks over performance and then sold as performance. I hate that every ford guy is like I can take such and such engine from xyz website and drop it in cuz its the only car ever that works this way (duh) and beat any car ever I can make 5-6-700hp blahblah and it will perfect. I have been unable to find one reasonable ford guy who realizes they their super engines are measured in hours.. haha I guess I just the south and mustangs...

    I can't say they are nice cars or particularly well engineered, but all I am saying is put 700hp in an e36, and 700hp in a fox body with some bolt on suspension and see which gets to the end of the 1/4 first. If the goal is to go drag racing (which mine is) then all BMW chassis are turds. Even for a handling car the latest mustangs are a peach.

    Then why are you in the thread about an e30 with a 9 inch rear end? If drags aren't your thing then I would leave the guy who thinks drags are awesome alone. You aren't going to change each others minds. Lol

    Hey why don't you calm down man, I wasn't saying its wrong to love drag or be all about drag if drags your thing its your thing. I definitely have never tried to change his mind. I checked the thread because he finally posted all his fabrication and his evolution. Which is epic for lack of a more proper word.
    I have not once said I didn't like what he has done nor have I said anything bad about his project. I love it, cars are supposto be individualistic and unique and he has done a fantastic job. OK?

    Someguy2800 - Are you going to retap the head bolts on this one as you've done it once before or leave it as standard?

    Great job with the design on the manifold Perry. I was down the shore this weekend but will catch up with you tomorrow. I have lots of numbers for you.

    finally done with the runner on the manifold. Still need to add the wastegate dumps but close enough. I'm very happy and proud of how it turned out. The only thing I'm not thrilled about is the weld quality on the runners. I played around with gas flow and amperage quite a bit but couldn't get the aesthetics I was looking for. Maybe it was the cheap Chinese weld el's?



    I started with a flange from AR design I bought off ebay. It was quite expensive but the other supplier I found was out of stock. For some reason they thought it would be a good idea to counter bore the flange to fit a round piece of tubing. Stupid and unnecessary in my opinion as the exhaust ports in an M50 is in an oval shape so they don't match anyway. In my case I got a mild steel flange and am using schedule 10 SS tubing so the tubing fit really loose in the counter bore anyway. To match the round tubing to the oval port opening I cut 1 inch pieces of tubing and crushed one end into an oval in the vice. I purposely left a small step at the top and bottom to serve as a reversion step.








    of course anytime you weld a piece of metal it shrinks, which when you weld a flange on one side it causes it to curl up and warp. What I like to do is weld the flange first before any of the tubing.



    then I straighten it in a press. Now you don't have to worry about warping anymore.



    I really like to make collectors out of bends rather than straight tubes. They are much more compact and I think they look nicer because the primaries attach parallel rather than splayed.



    Designed in solidworks. Made out of three elbows cut into a precise profile using a template










    The center is hollow so to attach them to the primary runners you stack up the 3 primary runners leaving a triangular hole in the center. I just weld the center hole shut using steel filler rod. If you felt like it I suppose you could fabricate a cone or peak to weld in the center. Then you just set the collector on top and weld the outside perimeter to seal it all up.



    here is the end result



    The primaries are about 10 inches in length and are all within an inch of each other. the secondaries are about 13 and are also within and inch of each other. I personally don't believe equal length really matters much but it sure looks nice. The extra length should add some considerable top end. For those curious I have about 30-40 hours of work into this, and about $350 in materials and welding gas. There is a very good reason why custom tubular manifolds and headers cost as much as they do!

    Someguy2800 - Did you get those rods from 5nails? Just curious to know the length of it and the weight as well.

    weight = 393 grams
    big end bore = 48mm
    small end bore = 22mm
    length = 135mm

    Same dimensions as M20b25, m50 NV, M52, S50, S52 and others. Also interesting, the rod bolts are only 8mm thread size as opposed to all m5x rods which are 9mm thread.

    After I blow this motor up I'll probably do a rebuild on my 2.8 liter with these rods and some 11:1 wiesco's for 40 psi of boost on a 72mm or 76mm turbo.
