Ted B.'s HTA3582 Twinscroll Project
Ted B.'s HTA3582 Twinscroll Project
Well folks, let me begin by saying that I can't tell you yet what type of power it makes, simply because I don't (yet) have enough fuel injection capacity to get there 
, so consider this a sneak preview. But what I can tell you is that even with the dual Walbros flowing 50psi base FP, FIC 1250s at 100+% IDC, and 12.2 AFRs with E85 at 29psi, it's a hoot . . . even with my quick-n-dirty tune.
The HTA3582 with twinscroll T4 really works. I've had a 35R with open .63 A/R before, but it wasn't anything like this. There are no dead spots. It picks up from an idle in 1st gear and just feels like the car is rolling downhill all the way. I'm hitting 20psi almost 1000rpm quicker than I did with the open T3 35R, and the big 1.06 A/R TS T4 flows well enough to see the limits of anything this turbo can deliver on any fuel.
Originally I had the HTA3582 reserved for my BMW and had an HTA3586 on order. When that lingered on for weeks, we just decided to wrap things up with the '82' and check it out. I was so impressed with the response that I canceled the '86' order. I'm staying right where I am. Even when I go to 1450cc injectors, I'll have more turbo than fuel, so I let that be the final determing factor.
A few photos follow below . . .
Anyone recognize those polished billet cams?

Some goodies visible here
Ignore the Dixie beer bottle, we found it to have little performance benefit
Intake side closeup - a few more goodies visible here
This effort was sponsored by no one but myself. Various items were purchased from many of our participating vendors. Others were fabricated or developed to spec (not off-the-shelf items). The basic hardware is listed in my signature. The greatest credit goes to Morgan Performance Fabrication for all the custom fabrication work and engineering support, and Dyno4mance for the assembly and installation expertise.

If that catchcan breaths are you not worried about oil vapors going into your turbo? I mean I know its not gonna hurt the turbo but its gonna give your charge pipes one nice little lathering of oil, or is that what you intended so that the air flows easier lol. <---totally kidding on that part hence the lol. Car looks really good, cant wait to get my TS35r setup together. Does yours have the billet compressor wheel?

This turbo is the HTA3582, so it has a billet compressor wheel.
Thanks for the kind comments everyone.
Thats what i figured when you mentioned Hta. Ive been contemplating the billet compressor wheel, but for the minimal spool and power compliments for the money I will probably just stick with the original compressor wheel. The catch can Im building has an exhaust helper in getting rid of the oil vapors. I forget what they call it but run a line into the downpipe so the exhaust pressure sucks the oil vapors out of the catch can, and aids in getting the pressure out of the head as well. Get some videos of it, car sounds like a blast.
looks great ted...
we are running a TS T4 on our Time attack car... something smaller than yours, on a 2.3... should be VERY responsive...
also, you need a straight shot upper rad hose radiator
