No problem, just put it in there to test fit. Where it turns up to go into the turbo is ~3/4" from the frame rail.

 

Looking good

 

what's the inside diameter on your piping?

 

WHEW!!! that is close!


MWW

 

It's schedule 10 1.5" pipe. It has a ID of 1.68 and a ID of 1.9. The pipe ID is about the same size of the exit of the stock 13B-RE sleeve so I went with it.

 

Heh, you're telling me. Now it's just time to finish welding up the flanges and make my final decision on where I want to tap in for the WG runners.

 

that , my friend is the WORST part of making a header..tying the wg into the DP. here is my best advice: after you get everything close and tack welded take the assembly off of the car, bolt the header up to a dummy engine and make sure ALL of the nuts and bolts are tight before you finish weld. if you dont do this nothing will bolt back together due to the nature of stainless moving around while being welded

 

Thats why I made the engine flange holes 1/2 . I also plan on bolting the old cast exh manifold onto the flange while I weld the outside but not really sure yet what I am going to do when it comes to welding the inside of the tubes. Have any ideas?

 

what do you mean the inside of the tubes? if you are talking welding the engine side of the flange, i dont suggest welding both sides if you are not and experienced welder, the heat will make the SS unstable and soft. weld the outside and if you just have to weld the inside use silicone bronze rod at low heat.

So I should just weld the outside of both flanges? Not on the inside? What if I just welded one side and not the other, is that fine? I can only weld the inside of the turbo flange because of clearance issues (can't get the wand in between the two tubes). Will it eventually crack if I weld both sides (in and out)?

thanks for all the advice by the way

Great advice. You have obviously been there done that many times before. I like the pics I saw of your twin setup. You might like these. I got to see this earlier this month. FYO

 

Another - BTW they are using N20 to spool them

 

Wow! That is one sick intercooler!!!! Nice kit......who's is that? I haven't seen that one around or even heard about it.

 

Home made - the only way -

 

Dam thats a thick IC... are you going to run an oil cooler/coolers? Or is this a drag only car and thus does not need them.

 

I didn't make it. Only took the pics. ( Nice fab work though - well thought out ) Drag only car. I am not into drag racing - too hard on parts and zero room for mistakes. Takes a great deal of talent to stay competitive. I don't want to name names. If they wanted to post they would have.

 

Here is my problem with welding the outside of the pipes on the turbo flange side, just no room to get the TIG in there between the two. Can I get away with welding the pipes inside the turbo flange or will it eventually crack? Now welding the outside of the pipe on the engine flange side will be no problem.

thanks

Welding the inside or outside or both is no prob. Excessive heat with huge welds will damage the material as Turbostreetracer pointed out. Just make sure the material is spotless / CLEAN and you use enough shielding gas even after you finish the weld. ( 3 - 7 seconds ) Good luck and the manifold looks great so far.

 

So I'll be fine if I weld both the inner and outer of the pipes as long as I don't put the pedal to the metal with the TIG? So far I've been only told to weld the outside

 

I think I will get my "white weld" procedure out of the book at work and post it for you guys. Nuclear Helium Leak tight welding to 1 x 10 -6 !!!

 

What exactly is a "white weld" procedure?

 

Well here she is in the car all welded up less the WG runners, still deciding on a WG.

 

another

 

NIce!!!

I haven't had time to post the White-Weld Procedure, It is a method of Cleaning, pre-heating and backpurging to produce a contaminnent free and heat discoloration free wels in SS Steel.

 

I'd say about 95% of my welding was done by using the "fusion" or no filler rod method. Seemed that by doing this the welds turned out looking a lot more pure (maybe because of my lack of experience of TIG welding). I hope this is ok? I did hook up a back purge system and there was a noticeable difference in the weld quality (thanks maxthe7man for telling me to do that!).

banzaitoyota- if you ever get around to posting that white weld procedure I'd really like it. Never thought of preheating the metal..

I do have one question though. My turbo flange did warp little even though I had my turbine housing bolted to it. I was talking to a machinist buddy about machineing it flat for me but he didn't know how he'd clamp it in his mill and suggested just taking it to a belt sander. What have you guys done to re flaten the flanges?
