Also, It doesn't matter if it's structural or not, if the weld cracks you're leaking exhaust all over the place. I was just trying to find out what process is being used for this so that I can decide whether or not to give it a try.

Is Extrude reaaaaally needed? Probably not. However (IMO only) if you're going to go that far with a setup, it's worth doing it right (especialyl if you're really going to drive the car...if it's just a daily driver then I'd probably opt out). I guess that though process could be applied to a most mods, but I'm just trying to be as truthful as possible As far as a reduction in power, that's hard to say beyond educated guessing based upon results and dyno graphs. YOu'll gain faster spool up and torque with the stock manifold, but may loose out a smidge on the top end, which is where the tubular manifold does work best...however it's not a huge amount) Quote:

Looks good Cody, will be seeing me getting this done in the future! Been wanting to go external wastegate for some time now, just havent figured out how far of a set-up I want to go with as in daily driving use. That Swain coating looks real good on the manifold as well.

Stop being a douche. I was asking a question and was looking for an answer. Not some smart ass responses from someone other than the vendor. I have experience welding, I have taken welding classes, and I know many people who have tried to weld cast iron and failed. I looked into having this exact process done to my own manifold in the past and was turned down by local welding shops. I was curious of the process that they used, not trying to cause trouble, I know it can be done but I also know it's not as easy as you are making it out to be. And also, stop being a douche.

Just for the record, I answered your questions....in a respectful manner, then YOU gave a smartass response...if you already think you know, why ask? I'm done cluttering Cody aces thread. Sorry man.
P.s. still want that chicken dinner.

Don't mind my rigging here, but it works. WHat I did was used hardpipe off the flange and welded it down near the steering shaft. Then I welded flexpipe to it. On the downpipe itself I then welded an elbow, that allowed the dump pipe flex section to slide over it, and then used the guientine clamp to secure it, and allow it to be removable. I then wrapped it all with header wrap, and spray painted it with the DEI wrap paint stuff as another layer of heat control.

Yes, while removable, I kept my permanently recirculated. I don't really care for the sound of an open dump pipe asI like toned/quiet exhaust setup on my cars. You don't even hear anything extra this way, helps keep it 'sleeper/oem' to a degree, which is my style.

Yes I have flex Pipe in that piece. I don't really have many pictures of it, as I fabbed it and installed it and called it a day.
On my example, the upper red part is hard pipe. cut at an angle, and welded to the flange. The green part is the flexible tubing that I got from JCwhitney (1.25 or 1.5" I can't recall). The flexible tubing then slides atop more hard tube (again in red at the bottom) where it recirculates back into the downpipe (secured via that guillotine clamp). Could I have fabbed it with all hard pipe? Sure...but the flex tube was available and easy to use. It's a MFer to weld with a mig (I'm also not a perfect welder) so just be careful with it, or have someone tig it. I had the mig super cold, and very fast to keep it from melting.

What about this? Special Turbine Housing T25-EWG-44 : atpturbo.com
Your alternative is a lot cheaper and is tried and true, and I'm sure there will be the same amount of fab required. Just wondering if anyone has went this route. Thanks! |

Hi Codyace. I have something in mind and wanted to ask you first. Is there a phone number I can call you at? Or you can email me back at [email protected]
I looked at the group buy for the cast iron manifold but couldn't find a link. Please, email me as soon as you read this. I am purchasing a non wastegated turbo and I need to know if what I have in mind is going to work. Thanks in advance. |

my thinking exactly. Ive been wanting to do this for a while but cant make up my mind. But i mean if you plan on staying bottom mount for a good while (like i do) then i think its a solid investment/upgrade. Cant wait to do this!

Anybody thought of doing the exact same thing (welding a flange for wastegate) into the turbo rear housing? gate is directly where the exhaust spins turbine so it would exhaust the not needed gas right there rather than way up in manifold? I am doing it this way to my RB20 turbo until i save and buy better manifold and turbo etc.
I like your work on the exhaust manifolds as well though, nice job |

^ atp make a turbine housing already. Their are fitment issues with wastegate and strut tower at the moment...
