Trying to figure out where to get a down pipe for an HTA35R .82 A/R T3. The only place I have seen T3 flanged downpipes that arent V-band is full race and they want $900 just for the turbo manifold. Also a setup question since I am not near the parts or car.

Have HTA35R with T3 3" 4 bolt inlet hooked to custom tublar mani fold with tial 44mm external wastegate and dump. Am I not running an o2 housing, also how is the downpipe hooked to the turbine exhaust? Been looking around for about an hour and cant find the info I need. If need I will buy a flange to hook to turbine outlet and get a custom downpipe made, but as noted is this the correct setup and is there suppose to be an o2 housing in there or does it not matter. Never run anything but stock turbo before.

 

Bump for any info, someone has to know something.. I know I am not the first person to build a not kit turbo setup...

 

O2 housing is for street and the o2 rarely works right anyway on a non stock system with out an ems

 

If ur not doing a major upgrade I suggest putting in the o2 sensors get a flange welded on

 

Build will be FP HTA35R T3 4 bolt .82 A/R, T3 tubular manifold w/tial 44mm wastegate and dump tube, BR2.3L RPM, JAM built head with supertech dual springs, BR BF 272's, Walbro 440LPH E85 Pump, ID 2000's injectors, AEM EMS, 65mm TB, ported intake mani, 4" ETS intake with speed density, 4" ETS FMIC, ETS lower and upper IC pipes, A/C delete, and all supporting mods.. should easily be a 800+HP car with right turbo but will see mostly street time and want it to be reliable so probably be running between 500-600
