This is why sets for the 350z cost upwards of $1600. Just throwing that out there.

Yup.

You need good quality tubing, with proper filler rod. The most important thing is back purging with argon, or another inert gas as well as a good gas lens for the tig torch.

I had a local customer who brought in a $1100 FD turbo manifold that was built out of SCH 10 pipe (nice and strong). The welding process was all wrong though. The manufacturer did not back purge and then did not weld with full amperage...the manifold was cracked in about 5 places after 6 months of use.

I re-did every single weld on the manifold (using proper welding procedures)...no issues with it after 3 years of abuse.

Feel like fixing some cracked GTM manifolds? Can you do it fast enough for Cosmo to not do something drastic from boost withdrawal?

That's a nice setup. I like those four stroke engines. First time I got in a boat with one I didn't even think it was running.

I have done it before...welding (arc/tig/mig) is not the right way to fix a cast manifold though

Ah, boats. Those things that make project cars seem cheap and reliable. I know, let's take most of the annoying things about engines, and partially immerse them in salt water. What could go wrong?

In all seriousness, that's a very nice rig. I don't want one myself, but I really want one of my close friends to buy one just like it.

Speaking of which Reininger's got one for the beach house

Basically, we're looking for someone to fix these damn things in a reasonable time frame. Seems like you might be able to weld a little bit.

Plus, it's yet another way GTM can continue to be the best salesman for BP's products and services.

You could try contacting speedforce racing but it won't be cheap.

Oh and before you listen to what this guy has to say keep in mind he was trying to tell Charles how to make a fuel return system and got owned....

I didnt get "owened" we agreed my way of doing the return system would work you just cant fit it on the z. If you read it there are things i said that he would like to do, there just isnt room.
