Tips? Suggestions? Past experience?

I now have a means to do some fabrication at home so when I do build a up pipe/down pipe combo I have a few theorys.
I would order some mandrel bent tubing. preferably stainless 1.5 or 1.75 and cut and weld with a engine block as a jig. I would also use heat wrap to keep it hot going into the turbo as that is supposed to help.

rallyruss: i know that theory for low speed power...but it really really makes the engien suffer at the high end, which is where these engines should really be making the power. Its fine for the average street driver, aka non perfomance minded "normal" person, but for some one like me, who is searching for power power power...seriously, look at the peak TQ, 2800 RPM on the turbos. Thats pretty low. The EJ engines have it around 4000. Granted our HP is up there, 4800, and then 5200 from 87+. The TQ drops of past 2800, I would like to move it to the 3000-4000 range, and push those HP figures up as well, not the RPM way, but just increase the figures. That and a DP, I am sure that we would pick up 10-15 HP alone from those mods. I do have the parts to make a Jig (extra turbo, heads, block, engine crossmember)...its jsut that I dont have the time, and I dont ahve a welder. I can get the pipe! Thats about it.

They're up for grabs on Ebay.com. (I bougt a new one and a 1500mi used one in one sale for 300 US$ a while back)

But then again...with an adapter plate...and a complete EJ20....

I should have also mentioned that I am running a modified down pipe on the RX and a subespeed one on thw wagon. they both help performance a good bit.

That DP i made is kinda killer. Too much flow on the little turbo tho. Boost creep. I had a thread about that. didnt you chime in?

The means of zero back pressure behind the turbo, i know that.
Now...before the turbo...thats where I have not gone before. I was thinking...make the pipes from each side the same size as the actual port...then size it down at the "Y" to the turbo.
Also.......massive idea I have had for a while about reducing turbo lag for large turbos....Jet engine exhaust nozzle. hehehehehe.

its a catless unit, but maybe a slightly larger diameter wouldnt be too bad of an idea however ive heard the same thing that rallyruss said.
