What's the problem with 16 gauge? You're saying it's too thin??? I've never seen a turbo manifold made with anything other than 16 gauge. Maybe I'm not understanding the problem.
I'd still be happy to help with your manifolds Telion. Let me know if there's anything I can do.

 

[reboticon]

What about just porting the stock manifolds? From everything i have read equal length headers are not a huge deal when dealing with a turbo. Especially when its very close to the head and can still flow enough. You might have some strange things happening at 6000+ rpm from extra back pressure on cyl 1 and 4, but the 3 to 1 straight design of them would definitely spool the turbos faster at low rpms.

16 ga. is pretty much where its at for turbo builds.

Stainless steel 16 guage I agree would be fine but a mild steel 16 guage is what is in quetion, I really wnat these headers done though so for all those willing to help I truly appreciate it. What I think I need to do is get a set of stainless steel headers mocked up and weld ready and then possibly send them to Kho or Vic's guy. Kho since you are on here can you look at the last pic and let me know what it would run to weld something like that up via PM considering the welds would be out of stainless and be welded at each bend, at the runners and where the merge is?

"Thin walled mild steel header (generally 16 to 18 gauge) tubing is inexpensive and easy to work with, but is not strong and will fatigue (and crack) quickly from the high temperatures and mechanical stresses a turbocharger will put on it. Thin mild steel also dissipates heat quickly, reducing the turbocharger efficiency. You can wrap the tubes with insulating material, but more heat means the metal fatigues and breaks more quickly." forgot to mention this was a quote from Megasquirt.

Telion just curious the welder you have he IS welding completely around the beads right? As in he welds the outside of the piping and inside? If so that should be enough and won't crack because of weak welds.

 

[Telion]

Well technically at the moment I don't have a welder for this project because he cannot weld stainless steel. So I am going to put my self in a position to just pay for this to be done by whom ever I can get to do it at a reasonable price. But yes the way he was welding did gain full penetration of the metal teh question was not so much the weld as it was the material. I would like these to be able to last a while though so I am going to pay for a little higher end product.

16 ga mild steel is plenty stong enough, especially when properly coated. its what Im using.

Telion I know my welder would be able to weld all metals including stainless if you wanted. He might not come cheap but he does a weld job that would mimic a machine. I had actually talked to him about reversing the obx headers and if they would just cut and mount a flange and make up a downpipe/exhaust. They actually planned it all out with me. IF that was all the welds. But for making complete headers he said look around 1500-2000 fully stainless.

 

[legend coupe]

not a bad price if its as good as you say.

 

[Telion]

Hmm, this is definately the cost effective way to go even once hot jetted. This would allow me to do it locally through mutual aquaintances. This is comforting.

Now for another saga be it good or bad, I received convincing information that my tranny is actually a 5 speed. ECU they said to have come from the same car is a PY3-A04.

 

[Telion]

Just a little bit more space making not much of an update but space is one of the things we lack. PS sorry for the look of the engine bay she is still under renovation. and I am thinking about making something to cover some of this stuff to clean up the look a bit.

I guess I should mention the black box is the relay box that normally connects to the fan shroud.

 

[reboticon]

Did you have to extend the wires or just pull the harness over there? Did you see what Crowing was doing with an extra harness?

 

[Telion]

All I had to do was pull the wiring over, but who knows what else I have done to get it there I have moved or changed such as the projector swap but those are all minor wires to extend so no big deal there. I have see what The Crowing is doing and just didn't want to take all that on if I didn't have to.

 

[DandDEE]

Wow, as I look back what began as a turbo build on a budget has become a full blown project (beyond the budget). Now that I have come this far I am going to press forward as though this is the the final stage of the performance part of Killana's build. Then at a later time I will swap out the turbos for some that are a little more serious.

(and that is just the items I didn't already have)

hey T u wanna stick a price tag on this since i am torn between TBo and SP. and one other thing ( u know i always have questions) is there a specific supercharger kit that would work for our g2 cause my little Project should be coming up soon not to rain on your parade or anything

 

[Telion]

I am stll working on a supercharger kit that I hope to at some point offer as a kit. But as for now I encourage anyone to attempt either and share what you learn along the way as it will assit who ever is trying this themselves, including me
as for the price tag it is going to vary on many of these items depending on what you want to/are willing to spend
Now on a side note the material for the headers have arrived. I thought I would throuw together what I have in mind.

I am still indecisive about the collector

 

[Vic Cardenas]

WTF????? I thought you were going to give me the 350Z headers all cut up.
That would be more easy.

 

[Telion]

Yes it would be easier but I need for this setup to be able to endure an increased desire for power and honestly I think the 350z headers are closer to like 18 guage and with all the reading I have been doing the better way for me to go in this case is the direction above. Don't worry I know this is probably too involved for your guy.

 

[Vic Cardenas]

I'm not worried and no it's not too involved for Joe. If you want I can also find out how thick the 350Z headers are at my shop too.

 

[Vic Cardenas]

What is the flange form? What kind of steel is that and what kind of steel are the pipes?
