240Z Turbo Posted June 27, 2001 Share Posted June 27, 2001 Well, I have done the rough fitment and weld of the rear turbo setup. I should have it completed tomorrow by midday. I will have the front finished by next Tuesday. Anyway, not the most fun thing I have done, but a learning experience for the front turbo. You will notice that I used a boring bar to bore out 1.75" diameter x .170" depth into each port so that the SS tube would fit into the header flange and give a more secure fit for welding. Anyway, almost 1/2 way there and will post the pics of the finished rear stuff tomorrow. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted June 27, 2001 Share Posted June 27, 2001 Looking real good, nice job! You re-routing your steering shaft with a u-joint? Regards, Lone Quote Link to comment Share on other sites More sharing options...
240Z Turbo Posted June 27, 2001 Author Share Posted June 27, 2001 No, even with my motor set back about 1" it still clears the stearing shaft by about 1". I will take a pic tomorrow with the rear turbo bolted on so you can see the setup and clearances. BTW, I'm getting excited! Quote Link to comment Share on other sites More sharing options...
pparaska Posted June 27, 2001 Share Posted June 27, 2001 Looks great! I'm interested to see what the final header and snails look like on there! Quote Link to comment Share on other sites More sharing options...
Drax240z Posted June 27, 2001 Share Posted June 27, 2001 Looking good man! Am I seeing things, or is the pipe and turbo flange SS, and the head mating surface mild steel? Looking forwards to seeing the final results. Quote Link to comment Share on other sites More sharing options...
jeromio Posted June 27, 2001 Share Posted June 27, 2001 Wow. That looks really nice. I've made headers before which makes me all the more impressed by these pictures. What guage tubing is that, 16? Butt welds, or flare fit? Quote Link to comment Share on other sites More sharing options...

clint78z Posted June 27, 2001 Share Posted June 27, 2001 Fantastic workmanship, it is blended so nicely into the collector. Truely something you can be proud of. Quote Link to comment Share on other sites More sharing options...
Drax240z Posted June 27, 2001 Share Posted June 27, 2001 Ah I see. Thanks for clarifying that. I guess rather than warp, a SS flange that long would potentially crack under thermal expansion. So James, are you going to be turning out a few of these and offering them as a kit? Quote Link to comment Share on other sites More sharing options...
240Z Turbo Posted June 27, 2001 Author Share Posted June 27, 2001 Did you say kit? CHUCKLE! Actually, I am sending this header to my buddy Marcus and he is going to make a jig for the header in case someone wants one. I will not do downpipes at this point and it would be header alone. So to answer the question, yes this header will be available for purchase in the near future. Quote Link to comment Share on other sites More sharing options...
Sean 83ZXT Posted June 28, 2001 Share Posted June 28, 2001 Hrmmm combine the TWM 6 throttle body setup w/ your TT setup and I could have a crazy motor! Quote Link to comment Share on other sites More sharing options...
Drax240z Posted June 28, 2001 Share Posted June 28, 2001 Since we are on the subject, tell us a bit about the mitsu turbos. Does the turbo flange only fit that size of mitsu turbo, or would a smaller turbo fit too? How do their prices or used availability compare to a T3/T04?

240Z Turbo Posted June 28, 2001 Author Share Posted June 28, 2001 The flange is 5/8" from Clifford Performance for $49 and seems to be hot rolled steel. The tubing is .065" 304 Stainless and the turbo flange is 1/2" cold roll steel. I used 309 rod to weld the SS to steel and either 308 or 316 rod for SS to SS. I called several header companies that make good turbo headers and they all said not to use SS for the Header flange because it is too brittle. Alot of turbo headers use mild steel flanges and SS pipe. Trust me, I would not have done it if I didn't know and had not researched it. As far as the welds, they are all heli-ark's(spelling). I put a nice bevel on all the edges and then grinded them and whiped them with Acetone. Not too difficult, but time consuming. I just finished the rear and will post pics of it on my car with the rear turbo. Quote Link to comment Share on other sites More sharing options...
