Default What is the exhaust flange & dp flange size/type

I am still pondering the whole turbo upgrade ,But dont want to spend $5,000 as Quoted by arnold at pagparts, I'm sure it is a killer kit but that is almost half of what the car cost. just too much to spend on this car. I noticed several ot the garrett gt series use a T25 flange isnt that our exhause flange? so couldnt you use the factory exhaust mani? I know you wouldnt get 100% of the performance you can but, I cant see it hurting the performance insanely. If I had to put a hp # out there I would say around that magic 300hp if it is a little under so be it. and I was wondering what dp flange we have. I know there would be some custom welding for the exhaust because I'm sure the turbo isnt the same width, and some fabrication on the ic pipes. there has got to be a way, by the way in that kit price there was a clutch that would also be needed. and software. using stock ic, using my w/m. it was not just a turbo & some lines

We dont use anything simular to a T25 or any other garrett flange. The ATP elim uses the ko3 style turbine housing but flow is crappy and if you keep your stock manifold, flow sucks more.

If you want a little more punch, the only elim that is worth the money is the gt2x. It is based on the gt20 turbo and has been shown to make ~250whp and 300ftlbs. You can upgrade in stages by getting the turbo, lines, and tuning. Then later down the road you can swap to a free flowing manifold and dp.
