WHAT'S THIS?! HTA35r is off the car??
We had almost the entire kit on the car today.......almost. The header as you see it was bolted on tight, finished the downpipe. Put the wastegate on, it's sweet how it is set up.
The turbo is pretty low but not so low as the drain for the turbo won't work. I do have to get some fittings for it though.
The lower i/c pipe is the worste part and I didn't finish it. I wanted to get the header over to the machine shop for milling before the end of today.
I am HOPING the header is finished being milled tomorrow. If so I'll finish the wastegate dump tube and lower i/c pipe.
I am waiting on my brother to come back from his vacation this week (spending the week out at my house hunting). When he comes back I'll have him swap out this head gasket and then the car will be ready for the dyno.
The inlet to the Tial housing is VERY small comparing it to the Garrett housing. When you start studying it though the "throat" of the turbine housing looks identical. I am hoping it will make atleast the same power that it did before. If so I'll consider it gains as this set up is lighter than the old one.
Runners, I'm not sure if they are longer or shorter than Shearer's or the Full Race I took off. I did measure them today as I was curious how close we got 1/4 compared to 2/3. We were within 1" and that's fine with me. Hell I'd even call that equal length but don't care.
We did some flow bench testing of headers (and intakes too actually) quite a few years back. We did it when we were working heavily on my tube chassis car. We put a head on the flow bench and then spent a few days bolting headers/manifolds and tubing up to the head to see how it effected the head flow. (crazy how many things we done and tested over the years that I forget about)
Anyway, at the time we flowed the Turbonetics manifold, HKS manifold, some other odd ball header and then started putting tubing and bends up to the ports to see how they effected it. At that point I said to the guy who owns the flow bench, "Guess I'll go weld together a header." He went off on me (mildly) about how you can't just put tubes together, you have to know what you are doing etc. etc. I built the first header for the car and when it was done I took it over, had it milled and headed back to the flow bench. We put it on the same head and then put the header on, adding the header was like gaining .250 lift on the exhaust cam, which is freaking HUGE. He looks at me and says, "Well it should work, it's just a bunch of straight pipes." I got a chuckle out of it. The design was similar to what you see here except on the tube chassis car I didn't have to turn the collector down, it mounted straight out, so it was minimal bends. I don't know if Brent Rau's header is still like that or not but his (in my opinion atleast) was modeled after mine on his car.
I suppose we could sell this kit but you have to realize it is for a car with no A/C and I am running the small radiator in my car. In all honesty, I dont' have any desire to sell these. If the housing works though there will eventually be a header built to fit normal EVO's with A/C etc.
Tomorrow, if my header isn't milled, I am starting on another header, same basic design, T3 flange. I may change the location to make the rest of the job easier.

I haven't seen ND's headers, without a small radiator this design is impossible, does he run the small radiator?
9sec9, didn't you know I've built a twin scroll header for the 20GLT? One off too, it is sitting here doing nothing, tried to sell it about a year or so ago, nobody wanted it. Daniel ran it on his car, it's ceramic coated, I relocated the turbo down about 1-2" for a better collector/runner configuration when I did it so it takes a special downpipe, which also just so happens to be sitting here. You have our phone number
Might be REALLY cheap to YOU.
