the one I bought is 12mm flange and 44mm pipe. I appreciate your pics and consern. But I think that you missed the part about me making a spot for the external wastegate. So there is a good chance than the turbo position will be moved slightly.

pics asu pics!

Looks like it should do the job well for the price. Jon's manifolds are much superior though, both in design and build quality.

I've heard somewhere that you take a factory manifold, cut the manifold and weld a turbo flange on. Then mount the manifold upside down. I don't know if that will work but it is an intresting idea. Either way, I curious to see if it would be worth the time and effort by going the ebay way. I've seen the prices at the Korman site, ouch. Anyway, Asubimmer, I rootin' for ya.

Screamer I actually have a spare stock manifold here and it could work but the ebay one should be less work and it is more bling lol. If anyone needs a stock manifold let me know before it ends up on ebay!

What about exhaust pulses? It seems that the exhaust manifold pipes are not equally long, which affects the pulse waves. How is that taken into account in that design?

as I know for turbo engine it is not so important.

of course it�s important, it maximises efficiency of the manifold to flow pusles into the turbo without interference from the diffrent pulses

romkasponka · « **Reply #23 on:** January 07, 2007, 07:38:24 AM »

and you will get aditional 2hp?

Gunni · « **Reply #24 on:** January 07, 2007, 12:20:10 PM »

No it�s actually more and quicker spool and better scavenging of the cylenders

With turbo motors it is more important than in NA engines. It really can affect the performance of the turbo, if the exhaust pulses are not taken into account in the manifold design.

show me dyno graph;)

wow so much has happened since i have been in the SUCK. To be honest with you yes jons products are tested,tried and true to be a great product, but its an indefinate monopoly due to the fact no one else makes something for a better price(albeit cheaper product) and I had my hand in the manifold that asu chose back in november and with my collective 5 years turbo experience and asu's experience....and Korman, i have a good mindset that this will work, yea it may need tweaking but hell....even with minor tweaking and adjustment the thing will still be affordable....a few ponies that are bled off due to inefficiencies doesnt really matter in the twistys as where this car is designed for....but this is all just an IMO session. Good job asu looks great and hopefully i can get all my stuff together again, im the only e30 on base hah, and maybe by summer the only boosted e30, got the hobby shop and lifts to make it happen now!

how's it coming?

asubimmer · « **Reply #29 on:** January 22, 2007, 07:49:17 AM »

well its great, it still is in peices but next time I go home I am having it welded up by a mechanic at Korman that has been working there longer than I have been alive lol. I didn't have time to have it welded before I came back up to app. While its not going to be the same as jon's its going to be considerably cheaper and I'd venture to say they won't perform much different either. I would be glad to test his if he sent me one to see if it was even a noticable difference
